Description

[0001] This application is a division of a Chinese invention patent with an application date of March 4, 2021, application number CN202110242125.5, and name “Battery charging rack, charging compartment, and battery swap station or energy storage station with charging compartment”. Technical Field

[0002] The present invention relates to the field of battery replacement, and in particular to a battery charging rack, a charging compartment, and a battery replacement station or energy storage station with the charging compartment. Background Art

[0003] New energy vehicles are becoming more and more popular among consumers. The energy used by new energy vehicles is basically electricity. New energy vehicles need to be charged after the electricity is used up. Due to the limitations of current battery technology and charging technology, it takes a long time to fully charge new energy vehicles, which is not as simple and fast as refueling cars directly. Therefore, in order to reduce the waiting time of users, replacing the battery when the power of new energy vehicles is running out is an effective means.

[0004] Currently, electric vehicles are replaced with batteries at battery swap stations. If the battery needs to be replaced quickly, the battery swap cart will remove the deflated battery from the electric vehicle and transport it to the charging area, and the battery transfer device will transport the deflated battery to the battery charging rack for storage and charging; and the battery transfer device will take out the fully charged battery from the battery charging rack and transport it to the predetermined location in the battery swap area through the battery conveying equipment, and then the battery swap cart will install the fully charged battery on the electric vehicle.

[0005] The battery charging rack in the charging area includes a plurality of battery compartments, each of which is a simple frame structure for carrying battery packs. The battery transfer device matched with the battery charging rack usually includes an extension portion. During the process of transferring the battery pack, the battery pack is placed above the extension portion, and the extension portion can extend into the battery compartment, thereby transferring the battery pack to the battery compartment. However, when transferring the battery pack in this way, the final placement position of the battery pack in the battery compartment is very likely to deviate, resulting in the electrical connector in the battery compartment being unable to be accurately aligned with the battery pack. Since the battery compartment is a frame structure with only a load-bearing function, it is difficult to adjust the position of the battery pack. Summary of the invention

[0006] The technical problem to be solved by the present invention is to overcome the defect in the prior art that it is difficult to adjust the position of the battery pack in the battery compartment. Once the placement position deviates from the preset position, the electrical connector cannot be accurately aligned with the battery pack. A battery charging rack, a charging compartment and a battery swap station or energy storage station with a charging compartment are provided.

[0007] A battery charging rack comprises a plurality of vertically arranged battery compartments, each of which has a battery inlet and outlet, and the battery inlet and outlet are used for a battery transport device to store a battery pack on the battery charging rack or to take the battery pack out of the battery charging rack.

[0008] The battery compartment includes a first times-speed chain displacement mechanism, which is extended in the battery compartment along a first direction of the battery pack's entry and exit direction, and is used to drive the battery pack to move along the first direction.

[0009] In the present scheme, a first speed chain displacement mechanism is provided. On the one hand, the position of the battery pack in the first direction can be accurately adjusted. Since the electrical connector is usually provided on the side of the battery compartment, it is beneficial to align the battery pack with the electrical connector in the first direction, thereby facilitating the connection between the electrical connector and the battery pack. On the other hand, it can drive the battery pack to move from the battery transport device to the battery compartment, or drive the battery pack to move from the battery compartment to the battery transport device, thereby reducing the time for transferring the battery pack between the battery transport device and the battery compartment, and improving the battery replacement efficiency.

[0010] For different types of battery packs, especially for battery packs with different widths (corresponding to the first direction), the moving distance of the first double-speed chain displacement mechanism can be changed so that battery packs of different types can be located in the middle or preset position of the battery compartment, thereby being suitable for adjusting battery packs of different sizes, and the battery compartment has high universality. In addition, the first double-speed chain displacement mechanism adopts a double-speed chain structure, which can select the running speed of the chain, and use the speed-increasing function of the double-speed chain, so that the battery pack supported on it can run quickly; the conveying speed is accurate and stable, which can ensure the precise conveying of the battery pack.

[0011] Preferably, the first speed chain displacement mechanism is arranged at the bottom of the battery compartment.

[0012] In this solution, when the first speed chain displacement mechanism is arranged at the bottom of the battery compartment and the battery pack is located above the first speed chain displacement mechanism, when there are no other components in the battery compartment for carrying the battery pack, the first speed chain displacement mechanism can also play the role of carrying the battery pack. At the same time, it can save vertical space, reduce the height of the battery compartment, and arrange more battery compartments on the same battery charging rack.

[0013] Preferably, the battery compartment comprises a first stopping mechanism, which is arranged close to a side of the battery compartment opposite to the battery inlet and outlet, and is used to stop the battery pack in the first direction.

[0014] In this solution, the first stopping mechanism has a limiting effect on the battery pack, so that the battery pack can be accurately parked at a preset position in the battery compartment in the first direction.

[0015] Preferably, the first stopping mechanism is arranged to be movable along the first direction.

[0016] In this solution, the position of the first stopping mechanism in the first direction is adjustable to accommodate battery packs with different widths in the first direction, so that the battery compartment can carry battery packs of different sizes.

[0017] Preferably, a sensor is provided on the first stop mechanism, and the sensor is communicatively connected with a control unit of the first multiple-speed chain displacement mechanism;

[0018] The sensor is used to send a signal to the control unit after detecting that the battery pack is in contact with the first stopping mechanism, so that the control unit controls the first speed chain displacement mechanism to stop operating.

[0019] In this solution, the sensor is used to determine whether the battery pack is in contact with the first stop mechanism, thereby detecting whether the battery has reached the preset position. When the battery pack is in contact with the first stop mechanism, the sensor can immediately send a signal to enable the control unit to immediately control the first speed chain displacement mechanism to stop running.

[0020] Preferably, the battery compartment further comprises a guide mechanism, which is disposed on a side of the battery compartment close to the battery inlet and outlet, and is used to guide the battery pack so that the battery pack moves along a preset path in the battery compartment;

[0021] And / or, the battery compartment further includes a positioning mechanism, the positioning mechanism is arranged on two sides of the battery compartment adjacent to the battery inlet and outlet, and the positioning mechanism is used to position the battery pack.

[0022] In this solution, the guide mechanism is arranged on one side of the battery compartment close to the battery inlet and outlet, and can guide the battery pack to smoothly enter the battery compartment. The positioning mechanism is used to position the battery pack so that the battery pack is more firmly placed in the battery compartment.

[0023] Preferably, the battery compartment further comprises a battery carrying portion, the battery carrying portion is arranged on two sides of the battery compartment adjacent to the battery inlet and outlet, the battery carrying portion has a battery carrying surface, and the battery carrying surface is used to carry the battery pack;

[0024] The first speed chain displacement mechanisms are all located on the inner side of the battery carrying part.

[0025] In this solution, by providing a battery carrying part, after the first times speed chain displacement mechanism moves the battery pack to a preset position, the battery pack can be carried only by the battery carrying part. In this case, the first times speed chain displacement mechanism is only used to adjust the position of the battery pack, thereby avoiding excessive wear of the first times speed chain displacement mechanism, maintaining its accuracy during use, and improving its service life. The first times speed chain displacement mechanisms are all located on the inner side of the battery carrying part, so that the placement of the battery pack on the battery carrying part is more balanced, thereby improving the stability of the battery pack.

[0026] Preferably, the battery compartment further comprises a first lifting mechanism, the first lifting mechanism being used to move the first times-speed chain displacement mechanism in a vertical direction, and a moving path of the first times-speed chain displacement mechanism in the vertical direction has a first upper limit position and a first lower limit position;

[0027] Among them, when the first speed chain displacement mechanism reaches the first upper limit position, the battery contact surface of the first speed chain displacement mechanism is not lower than the battery bearing surface in the vertical direction, so that the first speed chain displacement mechanism drives the battery pack to move along the first direction; when the first speed chain displacement mechanism reaches the first lower limit position, the battery contact surface of the first speed chain displacement mechanism is not higher than the battery bearing surface in the vertical direction, so that the battery bearing surface can bear the battery pack.

[0028] In this solution, the first lifting mechanism is provided to realize the switching of the battery pack between the first speed chain displacement mechanism and the battery carrying part. When the battery pack needs to be moved, the first lifting mechanism drives the first speed chain displacement mechanism to rise, thereby avoiding interference of the battery carrying surface with the movement of the battery pack. When the battery pack needs to be fixedly placed, the first lifting mechanism drives the first speed chain displacement mechanism to descend, and the battery pack falls on the battery carrying part, thereby protecting the first speed chain displacement mechanism.

[0029] Preferably, the battery carrying portion further includes a ball bearing, the ball bearing is arranged between the battery carrying portion and a contact surface of the battery pack, and the ball bearing is extended along the first direction.

[0030] In the present solution, by arranging ball bearings, the battery pack can also be moved on the battery carrying part. Therefore, when the battery pack is moved, the first speed chain displacement mechanism does not need to rise to be higher than the battery carrying part. The battery contact surface of the first speed chain displacement mechanism only needs to be at the same height as the battery carrying surface to move the battery, thereby reducing the vertical movement stroke of the first speed chain displacement mechanism and achieving an energy-saving effect. In addition, when the battery contact surface and the battery carrying surface are at the same height, the battery carrying part can share part of the weight of the battery pack, thereby further avoiding wear of the first speed chain displacement mechanism.

[0031] Preferably, the battery compartment further comprises an electrical connector, which is used to be connected to the battery pack to charge the battery pack, and the electrical connector is arranged on any side of the battery compartment adjacent to the battery inlet and outlet.

[0032] In this solution, the electrical connector is arranged on the side of the battery compartment to facilitate charging of the battery pack.

[0033] Preferably, the battery compartment also includes a second speed chain displacement mechanism, which is extended in the battery compartment in a second direction perpendicular to the entry and exit direction, and the second speed displacement mechanism is used to drive the battery pack to move along the second direction so that the battery pack is connected to the electrical connector.

[0034] In the present solution, the second times-speed chain displacement mechanism is used to drive the battery pack to move in the second direction. On the one hand, it enables the battery pack to move in the direction toward or away from the electrical connector, thereby facilitating accurate electrical connection or disconnection between the electrical connector and the battery pack, and is suitable for battery packs of different sizes, especially battery packs with different lengths in the second direction. On the other hand, for battery packs of different models, especially battery packs with different lengths (corresponding to the second direction), the moving distance of the second times-speed chain displacement mechanism can be changed so that battery packs of different models can be located in the middle position or preset position of the battery compartment, thereby being suitable for adjusting battery packs of different sizes, and the battery compartment has high universality.

[0035] Preferably, the battery compartment further comprises a second lifting mechanism, the second lifting mechanism being used to move the second speed chain displacement mechanism in a vertical direction, and the movement path of the second speed chain displacement mechanism in the vertical direction has a second upper limit position and a second lower limit position;

[0036] The battery compartment further comprises a battery carrying portion, the battery carrying portion is arranged on two sides of the battery compartment adjacent to the battery inlet and outlet, the battery carrying portion has a battery carrying surface, and the battery carrying surface is used to carry the battery pack;

[0037] The second speed chain displacement mechanism is located inside the battery carrying portion;

[0038] Among them, when the first speed chain displacement mechanism reaches the second upper limit position, the battery contact surface of the second speed chain displacement mechanism is not lower than the battery bearing surface in the vertical direction, so that the second speed chain displacement mechanism drives the battery pack to move along the second direction; when the second speed chain displacement mechanism reaches the second lower limit position, the battery contact surface of the second speed chain displacement mechanism is not higher than the battery bearing surface in the vertical direction, so that the battery bearing surface can bear the battery pack.

[0039] In this solution, the switching of the battery pack between the second speed chain displacement mechanism and the battery carrying part is realized by setting a second lifting mechanism. When the battery pack needs to be moved along the second direction, the second lifting mechanism drives the second speed chain displacement mechanism to rise, thereby avoiding interference of the battery carrying surface with the movement of the battery pack. When the battery pack needs to be fixedly placed, the second lifting mechanism drives the second speed chain displacement mechanism to descend, and the battery pack falls on the battery carrying part, thereby protecting the second speed chain displacement mechanism.

[0040] Preferably, the battery compartment also includes a first pushing mechanism, which is located on the same side as the electrical connector, and is used to push the electrical connector toward or away from the battery pack so that the electrical connector is electrically connected to or disconnected from the battery pack; and / or, the battery compartment also includes a second pushing mechanism, which is located on the side opposite to the electrical connector, and is used to push the battery pack toward or away from the electrical connector so that the electrical connector is electrically connected to or disconnected from the battery pack.

[0041] In this solution, by providing a first pushing mechanism, the electrical connector can be moved to achieve electrical connection or disconnection with the battery pack. Compared with moving the battery pack, only moving the electrical connector makes the battery pack more stable in the battery compartment. By providing a second pushing mechanism, the battery pack can also be moved in a second direction to achieve electrical connection or disconnection with the battery pack. Alternatively, through the combined action of the first pushing mechanism and the second pushing mechanism, the battery pack and the electrical connector can move closer to or farther from each other at the same time, thereby improving the connection efficiency.

[0042] Preferably, a second stopping mechanism is provided on a side of the battery compartment away from the electrical connector, for stopping the battery pack in a second direction perpendicular to the entry and exit direction, so that the electrical connector maintains electrical connection with the battery pack.

[0043] In this solution, by providing a second stopping mechanism, during the connection between the electrical connector and the battery pack, the battery pack can be restricted from moving in a direction away from the electrical connector, thereby preventing the first pushing mechanism from being too strong and pushing the battery pack away, thereby facilitating electrical connection between the electrical connector and the battery pack.

[0044] A charging bin, comprising a battery transfer device and the battery charging rack as described above, wherein the battery transfer device is arranged on a side of the battery charging rack having a battery inlet and outlet, and the battery transfer device is used to store a battery pack on the battery charging rack or take the battery pack out of the battery charging rack.

[0045] In this solution, the battery charging rack is applied in the charging bin, which correspondingly reduces the time for transferring the battery pack between the battery transport device and the battery bin, improves the battery replacement efficiency, and can accurately adjust the position of the battery pack in the first direction, which facilitates the connection between the electrical connector and the battery pack and improves the connection efficiency. At the same time, it ensures that the battery pack can be accurately adjusted in the battery charging rack, making the storage position of the battery pack more accurate so as to facilitate the electrical connector to charge in the first direction.

[0046] A battery swap station or energy storage station, wherein the battery swap station or energy storage station comprises the charging compartment as described above.

[0047] In this solution, a charging bin with the above-mentioned battery charging rack is used in a battery swap station or energy storage station, which correspondingly reduces the time for transferring the battery pack between the battery transport device and the battery bin, thereby improving the battery swap efficiency, and can accurately adjust the position of the battery pack in the first direction, facilitating the connection between the electrical connector and the battery pack, thereby improving the connection efficiency.

[0048] On the basis of being in accordance with the common sense in the art, the above-mentioned preferred conditions can be arbitrarily combined to obtain the preferred embodiments of the present invention.

[0049] The positive and progressive effects of the present invention are:

[0050] For the battery charging rack, a first speed chain displacement mechanism is provided. On the one hand, the position of the battery pack in the first direction can be accurately adjusted. Since the electrical connector is usually provided on the side of the battery compartment, it is advantageous to align the battery pack with the electrical connector in the first direction, and facilitate the connection between the electrical connector and the battery pack. On the other hand, it can drive the battery pack from the battery transport device to the battery compartment, or drive the battery pack from the battery compartment to the battery transport device, thereby reducing the time for the battery pack to be transferred between the battery transport device and the battery compartment and improving the battery replacement efficiency. For different models of battery packs, especially for battery packs with different widths, the moving distance of the first speed chain displacement mechanism can be changed so that battery packs of different models can be located in the middle position or preset position of the charging compartment, thereby being suitable for adjusting battery packs of different sizes, and the charging compartment has high universality.

[0081] This embodiment discloses a battery charging stand 100. Figure 1-5 As shown, the battery charging rack 100 includes a plurality of vertically arranged battery compartments 1, each battery compartment 1 having a battery inlet and outlet 104, the battery inlet and outlet 104 being used for the battery transport device 200 to store the battery pack 300 on the battery charging rack 100 or to take the battery pack 300 out of the battery charging rack 100, the battery compartment 1 includes two first times speed chain displacement mechanisms 101, the first times speed chain displacement mechanisms 101 are extended in the battery compartment 1 along the first direction of the battery pack 300 in and out, and are used to drive the battery pack 300 to move, so as to adjust the position of the battery pack 300 in the first direction a1. In other embodiments, the number of first times speed chain displacement mechanisms 101 can be increased or decreased according to actual design requirements.

[0082] In the present embodiment, a first double-speed chain displacement mechanism 101 is provided. On the one hand, it can drive the battery pack 300 to move from the battery transport device 200 to the battery compartment 1, or drive the battery pack 300 to move from the battery compartment 1 to the battery transport device 200, thereby reducing the time for the battery pack 300 to be transferred between the battery transport device 200 and the battery compartment 1, and improving the battery replacement efficiency; on the other hand, it can accurately adjust the position of the battery pack 300 in the first direction a1. Since the electrical connector is usually provided on the side of the battery compartment 1, it is beneficial for the battery pack 300 to be aligned with the electrical connector in the first direction a1, and it is convenient for the electrical connector to be connected to the battery pack 300. In addition, the first double-speed chain displacement mechanism 101 adopts a double-speed chain structure, which can select the running speed of the chain. By using the speed-increasing function of the double-speed chain, the battery pack 300 supported thereon can run quickly; the conveying speed is accurate and stable, which can ensure the accurate conveying of the battery pack 300. For different types of battery packs 300, especially battery packs with different widths (corresponding to the first direction a1), the moving distance of the first speed chain displacement mechanism 101 can be changed so that the different types of battery packs 300 can be located in the middle position or preset position of the battery compartment 1, thereby being suitable for adjusting battery packs 300 of different sizes, and the battery compartment 1 has high universality.

[0083] It should be noted that if Figure 1 and Figure 3 As shown, the first direction a1 in this embodiment refers to the in-and-out direction of the battery pack 300. The first double-speed chain displacement mechanism 101 in this embodiment is based on a double-speed chain structure. The double-speed chain can refer to a material conveying machine that uses a chain as a traction and carrier, which is a type of conveyor and can transport large items at one time.

[0084] In one embodiment, the first times speed chain displacement mechanism 101 is disposed at the bottom of the battery compartment 1. The first times speed chain displacement mechanism 101 is disposed at the bottom of the battery compartment 1, and the battery pack 300 is located above the first times speed chain displacement mechanism 101. In the case where there are no other components in the battery compartment 1 for carrying the battery pack 300, the first times speed chain displacement mechanism 101 can also play the role of carrying the battery pack 300. At the same time, since the first times speed chain displacement mechanism 101 is disposed at the bottom of the battery compartment 1, vertical space can be saved, the height of the battery compartment 1 can be reduced, and more battery compartments 1 can be arranged on the same battery charging rack.

[0085] The battery compartment 1 may include a first stop mechanism (not shown), which is disposed on a side of the battery compartment 1 opposite to the battery inlet and outlet 104, and is used to stop the battery in a first direction. The first stop mechanism has a limiting effect on the battery pack 300, so that the battery pack 300 is accurately parked at a preset position in the battery compartment 1 in the first direction a1. The preset position refers to the position of the battery pack 300 in the battery compartment 1 pre-set by the operator, which allows the battery pack 300 to be accurately aligned with the electrical connector 106.

[0086] In a preferred embodiment, the first stopping mechanism can be configured to be movable in the first direction a1, and the position of the first stopping mechanism in the first direction a1 can be adjusted to accommodate battery packs 300 with different widths in the first direction, so that battery packs 300 of different sizes can be stored in the battery compartment 1.

[0087] In one embodiment, the first stop mechanism may include a driving part and a stop part, the driving part is used to drive the stop part to rise and fall vertically, when a battery pack 300 enters, the driving part drives the stop part to rise to stop the battery pack 300, when no battery pack 300 enters, or after the battery pack 300 has been positioned, the driving part drives the stop part to descend, thereby saving space inside the battery compartment 1. In another embodiment, the first stop mechanism may also include only the stop part, regardless of whether a battery pack 300 enters, the stop part is vertically arranged on the side of the battery compartment 1 opposite to the battery inlet and outlet 104.

[0088] The first stop mechanism may be provided with a sensor (not shown), which is communicatively connected with the control unit of the first times-speed chain displacement mechanism 101; the sensor is used to send a signal to the control unit after detecting that the battery pack 300 is in contact with the first stop mechanism, so that the control unit controls the first times-speed chain displacement mechanism 101 to stop running. The sensor is used to determine whether the battery pack 300 is in contact with the first stop mechanism, so as to detect whether the battery reaches a preset position. When the battery pack 300 is in contact with the first stop mechanism, the sensor can immediately send a signal so that the control unit immediately controls the first times-speed chain displacement mechanism 101 to stop running. The sensor can be a limit switch, a proximity switch, etc., or other sensors with the same function.

[0089] The battery compartment 1 may further include a guide mechanism (not shown), which is disposed on one side of the battery compartment 1 close to the battery inlet and outlet 104, and is disposed on both sides of the first speed chain displacement mechanism 101, and is used to guide the battery pack 300 so that the battery pack 300 moves along a preset path in the battery compartment 1. The guide mechanism is disposed on one side of the battery compartment 1 close to the battery inlet and outlet 104, and can guide the battery pack 300 to smoothly enter the battery compartment 1.

[0090] The battery compartment 1 may further include a positioning mechanism (not shown), which is disposed on both sides of the battery compartment 1 adjacent to the battery inlet and outlet 104 and is used to position the battery pack 300. The positioning mechanism is used to position the battery pack 300 so that the battery pack 300 is more firmly placed in the battery compartment 1.

[0091] The battery compartment 1 may also include a battery carrying portion 103, which is disposed on both sides of the battery compartment 1 adjacent to the battery inlet and outlet 104, and the battery carrying portion 103 has a battery carrying surface 1031, and the battery carrying surface 1031 is used to carry the battery pack 300. By providing the battery carrying portion 103, after the first times speed chain displacement mechanism 101 moves the battery pack 300 to a preset position, the battery pack 300 can be carried only by the battery carrying portion 103. In this case, the first times speed chain displacement mechanism 101 is only used to adjust the position of the battery pack 300, thereby avoiding excessive wear of the first times speed chain displacement mechanism 101, maintaining its accuracy during use, and improving its service life. The battery carrying portion 103 includes a carrying plate and a connecting plate, and the carrying plate and the connecting plate form a frame structure. Being set as a frame structure can reduce the weight of the battery carrying portion 103 while ensuring that the battery charging rack 100 is sufficiently stable.

[0092] It should be noted that, in this embodiment, the first times-speed chain displacement mechanism 101 is located inside the battery carrying part 103, so that the placement of the battery pack 300 on the battery carrying part 103 is more balanced, thereby improving the stability of the battery pack 300. In other alternative embodiments, the first times-speed chain displacement mechanism 101 can also be respectively arranged outside the battery carrying part 103, or one part can be arranged outside and the other part can be arranged inside, as long as the two do not interfere with each other in the vertical direction.

[0093] It should be noted that in other alternative embodiments, the battery compartment 1 may not be provided with the battery carrying portion 103. In this case, the first speed chain displacement mechanism 101 has the functions of adjusting the position of the battery pack 300 and carrying the battery pack 300, which simplifies the structure of the entire battery compartment 1 and reduces the cost.

[0094] The battery compartment 1 may further include a first lifting mechanism (not shown), the first lifting mechanism being used to move the first times-speed chain displacement mechanism 101 in a vertical direction, and the movement path of the first times-speed chain displacement mechanism 101 in the vertical direction has a first upper limit position and a first lower limit position;

[0095] Among them, when the first speed chain displacement mechanism 101 reaches the first upper limit position, the battery contact surface of the first speed chain displacement mechanism 101 is not lower than the battery supporting surface 1031 in the vertical direction, so that the first speed chain displacement mechanism 101 drives the battery pack 300 to move along the first direction a1; when the first speed chain displacement mechanism 101 reaches the first lower limit position, the battery contact surface of the first speed chain displacement mechanism 101 is not higher than the battery supporting surface 1031 in the vertical direction, so that the battery supporting surface 1031 supports the battery pack 300.

[0096] By providing the first lifting mechanism, the battery pack 300 can be switched between the first speed chain displacement mechanism 101 and the battery carrying part 103. When the battery pack 300 needs to be moved, the first lifting mechanism drives the first speed chain displacement mechanism 101 to rise, thereby preventing the battery carrying surface 1031 from interfering with the movement of the battery pack 300. When the battery pack 300 needs to be fixedly placed, the first lifting mechanism drives the first speed chain displacement mechanism 101 to descend, and the battery pack 300 falls on the battery carrying part 103, thereby protecting the first speed chain displacement mechanism 101.

[0097] The battery carrying part 103 may also include a ball bearing 1032, which is disposed between the contact surface of the battery carrying part 103 and the battery pack 300, and the ball bearing 1032 is extended along the in-and-out direction of the battery pack 300 or the first direction a1. By providing the ball bearing 1032, the battery pack 300 can also be moved on the battery carrying part 103, so that when the battery pack 300 is moved, the first speed chain displacement mechanism 101 does not need to rise above the battery carrying part 103, and the battery contact surface of the first speed chain displacement mechanism 101 only needs to be at the same height as the battery carrying surface 1031 to move the battery, thereby reducing the vertical movement stroke of the first speed chain displacement mechanism 101 and achieving energy saving effect; in addition, when the battery contact surface and the battery carrying surface 1031 are at the same height, the battery carrying part 103 can share part of the weight of the battery pack 300, thereby further avoiding the wear of the first speed chain displacement mechanism 101.

[0098] The battery compartment 1 further includes an electrical connector 106, which is used to connect to the battery pack 300 to charge the battery pack 300. The electrical connector 106 is disposed on either side of the battery compartment 1 adjacent to the battery inlet and outlet 104. The electrical connector 106 is disposed on the side of the battery compartment 1 to facilitate charging of the battery pack 300.

[0099] The battery compartment 1 also includes two second speed chain displacement mechanisms 107, which are extended along the second direction a2 in the battery compartment 1 and are used to drive the battery pack 300 to move along the second direction a2 so that the battery pack 300 can be connected to the electrical connector 106; wherein the second direction a2 refers to a direction perpendicular to the first direction a1. In other embodiments, the number of the second speed chain displacement mechanisms 107 can be increased or decreased according to actual design requirements.

[0100] The second times-speed chain displacement mechanism 107 is used to drive the battery pack 300 to move along the second direction. On the one hand, it enables the battery pack 300 to move in the direction toward or away from the electrical connector 106, thereby facilitating the precise electrical connection or disconnection between the electrical connector 106 and the battery pack 300, and is suitable for battery packs 300 of different sizes, especially battery packs 300 of different lengths in the second direction. On the other hand, when the battery transport device 200 takes out the battery pack 300 from the battery compartment 1, by adjusting the position of the battery pack 300 in the second direction, it is beneficial for the extension to accurately match the battery pack 300, thereby improving the battery replacement efficiency. In addition, for different types of battery packs, especially for battery packs 300 with different lengths (corresponding to the second direction), the moving distance of the second times-speed chain displacement mechanism 107 can be changed so that battery packs 300 of different types can be located in the middle position or preset position of the battery compartment 1, thereby being suitable for adjusting battery packs 300 of different sizes, and the battery compartment 1 has high universality.

[0101] In other alternative embodiments, the number of the first speed chain displacement mechanism 101 and the second speed chain displacement mechanism 107 can also be multiple, so as to increase the contact area with the battery pack 300 and improve the stability of the battery pack 300 during movement.

[0102] The battery compartment 1 may also include a second lifting mechanism (not shown), which is used to move the second speed chain displacement mechanism 107 in the vertical direction. The moving path of the second speed chain displacement mechanism 107 in the vertical direction has a second upper limit position and a second lower limit position; and the second speed chain displacement mechanism 107 does not interfere with the first speed chain displacement mechanism 101.

[0103] The battery compartment 1 also includes a battery carrying part 103, which is arranged on both sides of the battery compartment 1 adjacent to the battery inlet and outlet 104, and the battery carrying part 103 has a battery carrying surface 1031, and the battery carrying surface 1031 is used to carry the battery pack 300; the second speed chain displacement mechanism 107 is located on the inner side of the battery carrying part 103; wherein, when the first speed chain displacement mechanism 101 reaches the second upper limit position, the battery contact surface of the second speed chain displacement mechanism 107 is not lower than the battery carrying surface 1031 in the vertical direction, so that the second speed chain displacement mechanism 107 drives the battery pack 300 to move along the second direction; when the second speed chain displacement mechanism 107 reaches the second lower limit position, the battery contact surface of the second speed chain displacement mechanism 107 is not higher than the battery carrying surface 1031 in the vertical direction, so that the battery carrying surface 1031 carries the battery pack 300.

[0104] By providing a second lifting mechanism, the battery pack 300 can be switched between the second speed chain displacement mechanism 107 and the battery carrying part 103. When the battery pack 300 needs to be moved along the second direction, the second lifting mechanism drives the second speed chain displacement mechanism 107 to rise, thereby preventing the battery carrying surface 1031 from interfering with the movement of the battery pack 300. When the battery pack 300 needs to be fixedly placed, the second lifting mechanism drives the second speed chain displacement mechanism 107 to descend, and the battery pack 300 falls on the battery carrying part 103, thereby protecting the second speed chain displacement mechanism 107.

[0105] The first lifting mechanism and the second lifting mechanism can adopt one or more of a screw lifting mechanism, a horizontal screw mechanical lifting mechanism, a hydraulic lifting mechanism, etc. The first lifting mechanism is arranged at both ends or below the first speed chain displacement mechanism 101, and the second lifting mechanism is arranged at both ends or below the second speed chain displacement mechanism 107, so as to make the lifting process of the first speed chain displacement mechanism 101 and the second speed chain displacement mechanism 107 more stable.

[0106] The battery compartment 1 may further include a first pushing mechanism 109, which is located on the same side as the electrical connector 106, and is used to push the electrical connector 106 toward or away from the battery pack 300 to electrically connect or disconnect the electrical connector 106 to the battery pack 300. By providing the first pushing mechanism 109, the electrical connector 106 can be moved to achieve electrical connection or disconnection with the battery pack 300.

[0107] The first pushing mechanism 109 includes a first driving member 1091, a first pushing member 1092 and a first pushing platform 1093. The first driving member 1091 and the first pushing member 1092 are arranged on the first pushing platform 1093. The first driving member 1091 provides a driving force to the first pushing member 1092 so that the first pushing member 1092 pushes the electrical connector 106. The first driving member 1091 can be a driving mechanism such as a driving motor or a cylinder, and the first pushing member 1092 can be a plate-like structure arranged vertically to increase the contact area with the electrical connector 106 and make the pushing process more stable.

[0108] The battery compartment 1 may also include a second pushing mechanism 110, which is located on a side opposite to the electrical connector 106. The second pushing mechanism 110 is used to push the battery pack 300 toward or away from the electrical connector 106 to electrically connect or disconnect the electrical connector 106 with the battery pack 300. By providing the second pushing mechanism 110, the battery pack 300 can also move along the second direction to achieve electrical connection or disconnection with the battery pack 300. The first pushing mechanism 109 and the second pushing mechanism 110 work together, and the battery pack 300 and the electrical connector 106 can move closer to or farther from each other at the same time, thereby improving the connection efficiency.

[0109] The second pushing mechanism 110 includes a second driving member 1101, a second pushing member 1102, and a second pushing platform 1103. The second driving member 1101 and the second pushing member 1102 are arranged on the second pushing platform 1103. The second driving member 1101 provides a driving force to the second pushing member 1102 so that the second pushing member 1102 pushes the battery pack 300. The second driving member 1101 can be a driving mechanism such as a driving motor or a cylinder, and the second pushing member 1102 can be a plate-like structure arranged vertically to increase the contact area with the battery pack 300 and make the pushing process more stable.

[0110] It should be noted that, in this embodiment, the battery compartment 1 has both the first pushing mechanism 109 and the second pushing mechanism 110. In other alternative embodiments, the battery compartment 1 may also be provided with only the first pushing mechanism 109 or the second pushing mechanism 110. When only the first pushing mechanism 109 is provided, compared with moving the battery pack 300, only moving the electrical connector 106 makes the battery pack 300 more stable in the battery compartment 1.

[0111] A second stop mechanism (not shown) is provided on the side of the battery compartment 1 away from the electrical connector 106. The second stop mechanism is used to stop the battery pack 300 in a second direction a2 perpendicular to the entry and exit direction, so that the electrical connector 106 maintains electrical connection with the battery pack 300. By providing the second stop mechanism, during the process of connecting the electrical connector 106 with the battery pack 300, the battery pack 300 can be restricted from moving in a direction away from the electrical connector 106, so as to avoid the battery pack 300 being pushed away by the excessive pushing force of the first pushing mechanism 109, thereby facilitating electrical connection between the electrical connector 106 and the battery pack 300.

[0112] The present embodiment also discloses a charging compartment 400, which includes a battery transfer device 200 and a battery charging rack 100 as described above. The battery transfer device 200 is disposed on a side of the battery charging rack 100 having a battery inlet and outlet. The battery transfer device 200 is used to store a battery pack 300 on the battery charging rack 100 or to remove the battery pack 300 from the battery charging rack 100, so that the battery pack 300 can be transferred between battery compartments 1 arranged along the vertical direction of the battery charging rack 100 or the battery pack 300 can be transferred between the battery charging rack 100 and the battery exchange area.

[0113] The battery charging rack 100 is applied in the charging compartment 400, which correspondingly reduces the time for transferring the battery pack 300 between the battery transport device 200 and the battery compartment 1, improves the battery replacement efficiency, and can accurately adjust the position of the battery pack 300 in the first direction a1, which facilitates the connection between the electrical connector and the battery pack 300 and improves the connection efficiency. At the same time, it ensures that the battery pack 300 can be accurately adjusted in the battery charging rack 100, so that the storage position of the battery pack 300 is more accurate, so as to facilitate the alignment and charging of the electrical connector 106 in the first direction.

[0114] The present embodiment also discloses a battery swap station 600, which includes a battery transfer device 200, a battery swapping device, a battery conveying device, a vehicle loading platform 500 and a battery charging rack 100 as described above; wherein, the battery transfer device 200 is arranged on one side of the battery charging rack 100, and the battery transfer device 200 is used to store the battery pack 300 on the battery charging rack 100 or to take the battery pack 300 out of the battery charging rack 100, and to transfer the battery pack 300 between the battery charging rack 100 and the battery swapping device through the battery conveying device; the vehicle loading platform 500 is used to carry electric vehicles; the battery swapping device is arranged below the vehicle loading platform 500, and is used to install the fully charged battery pack 300 on the electric vehicle, or to remove the low-charged battery pack 300 from the electric vehicle.

[0115] The application of the above-mentioned battery charging rack 100 in the battery exchange station 600 correspondingly reduces the time for transferring the battery pack 300 between the battery transport device 200 and the battery compartment 1, thereby improving the battery exchange efficiency, and can accurately adjust the position of the battery pack 300 in the first direction, which facilitates the connection between the electrical connector and the battery pack 300 and improves the connection efficiency.

[0116] The present embodiment also discloses an energy storage station, which includes a battery transfer device 200 and a battery charging rack 100 as described above; wherein the battery transfer device 200 is arranged on a side of the battery charging rack 100 having a battery inlet and outlet, and the battery transfer device 200 is used to store the battery pack 300 on the battery charging rack 100 or to take the battery pack 300 out of the battery charging rack 100, so that when performing daily maintenance and safety inspections on the battery packs 300 in the energy storage station, the battery packs 300 can be transferred between the battery compartments 1 arranged in the vertical direction of the battery charging rack 100.
