Description

[0001] This application is a divisional application of the Chinese patent application No. CN202110242125.5, filed on March 4, 2021, entitled "Battery charging rack, charging bin and battery swap station or energy storage station with charging bin". TECHNICAL FIELD

[0002] The present application relates to the field of battery swap, in particular to a battery charging rack, a charging bin and a battery swap station or an energy storage station with the charging bin. BACKGROUND

[0003] Nowadays, new energy vehicles are increasingly popular among consumers. The energy used by new energy vehicles is basically electric energy. New energy vehicles need to be charged after the electric energy is used up. Due to the limitations of 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. Therefore, in order to reduce the waiting time of users, replacing the battery when the electric energy of the new energy vehicle is almost exhausted is an effective means.

[0004] The existing battery replacement for electric vehicles is carried out in a battery swap station. In order to quickly replace the battery, the battery swap vehicle takes the depleted battery from the electric vehicle and transports it to the charging area. The battery transfer device transports the depleted battery to the battery charging rack for storage and charging. The battery transfer device takes the fully charged battery from the battery charging rack and transports it to the predetermined position in the battery swap area through the battery conveying equipment. Then, the battery swap vehicle installs the fully charged battery on the electric vehicle.

[0005] The battery charging rack in the charging area includes a plurality of battery bins, each of which is a simple frame structure for carrying a battery pack. The battery transfer device cooperating with the battery charging rack usually includes an extension part. During the transfer of the battery pack, the battery pack is placed above the extension part. The extension part can extend into the battery bin, thereby transferring the battery pack to the inside of the battery bin. However, when the battery pack is transferred in this way, the placement position of the battery pack in the battery bin is likely to deviate, which causes the electrical connector in the battery bin to be unable to accurately align with the battery pack. Since the battery bin is only a frame structure with a carrying function, it is difficult to adjust the position of the battery pack. SUMMARY

[0006] The technical problem to be solved by the present application is to overcome the defect in the prior art that the position of the battery pack in the battery bin is difficult to adjust. Once the placement position deviates from the preset position, the electrical connector cannot accurately align with the battery pack. The present application provides a battery charging rack, a charging bin and a battery swap station or an energy storage station with the charging bin.

[0007] A battery charging rack comprises a plurality of vertically arranged battery compartments, each of which has a battery inlet and outlet for a battery transfer device to place or take out a battery pack from the battery charging rack,

[0008] The battery compartment comprises a first speed-up chain displacement mechanism, which is arranged to extend in a first direction of the battery pack in and out direction within the battery compartment and is used to drive the battery pack to move in the first direction.

[0009] In the present scheme, the first speed-up chain displacement mechanism is arranged, on the one hand, to accurately adjust the position of the battery pack in the first direction, and on the other hand, to drive the battery pack to move from the battery transfer device to the battery compartment or to drive the battery pack to move from the battery compartment to the battery transfer device, thereby reducing the time for the battery pack to transfer between the battery transfer device and the battery compartment and improving the battery replacement efficiency.

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

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

[0012] In the present scheme, when the first speed-up chain displacement mechanism is arranged at the bottom of the battery compartment and the battery pack is located above the first speed-up chain displacement mechanism, the first speed-up chain displacement mechanism can simultaneously serve as a bearing for the battery pack without other components for bearing the battery pack in the battery compartment, thereby saving vertical space and reducing the height of the battery compartment so that more battery compartments can be arranged on the same battery charging rack.

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

[0014] In the present scheme, the first stop mechanism has a limiting effect on the battery pack, so that the battery pack is accurately parked at the preset position in the battery compartment in the first direction.

[0015] Preferably, the first stop mechanism is arranged to be movable in the first direction.

[0016] In this aspect, the position of the first stop mechanism in the first direction is adjustable to adapt to battery packs of different widths in the first direction, so that the battery compartment can carry battery packs of different sizes.

[0017] Preferably, a sensor is arranged on the first stop mechanism, which is in communication connection with the control unit of the first speed chain displacement mechanism.

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

[0019] In this aspect, the sensor is used to determine whether the battery pack is in contact with the first stop mechanism, so as to detect whether the battery reaches the preset position. When the battery pack is in contact with the first stop mechanism, the sensor can immediately send a signal to 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 arranged on one side of the battery compartment close to the battery inlet and outlet, which is used to guide the battery pack to move along a preset path in the battery compartment.

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

[0022] In this aspect, the guide mechanism is arranged on one side of the battery compartment close to the battery inlet and outlet, which 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 placed more stably in the battery compartment.

[0023] Preferably, the battery compartment further comprises a battery carrying part arranged on both sides of the battery compartment adjacent to the battery inlet and outlet, which has a battery carrying surface for carrying the battery pack.

[0024] The first speed chain displacement mechanism is located on the inner side of the battery carrying part.

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

[0026] Preferably, the battery compartment further comprises a first lifting mechanism for moving the first speed chain displacement mechanism in the vertical direction, and the moving path of the first speed chain displacement mechanism in the vertical direction has a first upper limit position and a first lower limit position.

[0027] 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 carrying surface in the vertical direction, so that the first speed chain displacement mechanism drives the battery pack to move in 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 carrying surface in the vertical direction, so that the battery carrying surface carries the battery pack.

[0028] In the scheme, by arranging the first lifting mechanism, the switching between the first speed chain displacement mechanism and the battery carrying part of the battery pack is realized. When the battery pack needs to be moved, the first lifting mechanism drives the first speed chain displacement mechanism to rise, avoiding the interference of the battery carrying surface to the movement of the battery pack. When the battery pack needs to be fixed, 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 part further comprises a ball arranged between the contact surface of the battery carrying part and the battery pack, and the ball is arranged to extend in the first direction.

[0030] In the scheme, by arranging the ball, the battery pack can also be moved on the battery carrying part, so that when the battery pack is moved, the first speed chain displacement mechanism does not need to rise above the battery carrying part, and 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 moving stroke of the first speed chain displacement mechanism in the vertical direction, and achieving the effect of energy saving. 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 the wear of the first speed chain displacement mechanism.

[0031] Preferably, the battery compartment further comprises an electrical connector for connecting to the battery pack to charge the battery pack, the electrical connector is arranged on either side of the battery compartment adjacent to the battery inlet and outlet.

[0032] In this scheme, the electrical connector is arranged on the side of the battery compartment, which is convenient for charging the battery pack.

[0033] Preferably, the battery compartment further comprises a second speed-up chain displacement mechanism, the second speed-up chain displacement mechanism is arranged to extend in a second direction perpendicular to the inlet and outlet direction in the battery compartment, and the second speed-up chain displacement mechanism is used to drive the battery pack to move along the second direction to achieve connection between the battery pack and the electrical connector.

[0034] In this scheme, the second speed-up chain displacement mechanism is used to drive the battery pack to move along the second direction, on the one hand, so that the battery pack can move towards or away from the electrical connector, thereby facilitating the electrical connector to achieve precise electrical connection or disconnection with the battery pack, and being 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 for battery packs with different lengths (corresponding to the second direction), the second speed-up chain displacement mechanism can be changed in moving distance, so that battery packs of different models can be located at the middle position or the 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 is used to move the second speed-up chain displacement mechanism along the vertical direction, and the moving path of the second speed-up 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 bearing part, the battery bearing part is arranged on both sides of the battery compartment adjacent to the battery inlet and outlet, and the battery bearing part has a battery bearing surface for bearing the battery pack.

[0037] The second speed-up chain displacement mechanism is located on the inner side of the battery bearing part.

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

[0039] In the scheme, the second lifting mechanism is arranged to realize the switching of the battery pack between the second speed chain displacement mechanism and the battery carrying part. When the battery pack needs to be moved in the second direction, the second lifting mechanism drives the second speed chain displacement mechanism to rise, avoiding the interference of the battery carrying surface to the movement of the battery pack. When the battery pack needs to be fixed, 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 further comprises a first pushing mechanism located on the same side as the electrical connector, the first pushing mechanism being used to push the electrical connector to move towards or away from the battery pack, so as to electrically connect or disconnect the electrical connector with the battery pack; and / or, the battery compartment further comprises a second pushing mechanism located on the opposite side of the electrical connector, the second pushing mechanism being used to push the battery pack to move towards or away from the electrical connector, so as to electrically connect or disconnect the electrical connector with the battery pack.

[0041] In the scheme, the first pushing mechanism is arranged to enable the electrical connector to move to realize electrical connection or disconnection with the battery pack. Compared with moving the battery pack, only moving the electrical connector makes the stability of the battery pack in the battery compartment better. The second pushing mechanism is arranged to enable the battery pack to move in the second direction to realize electrical connection or disconnection with the battery pack. Alternatively, through the joint action of the first pushing mechanism and the second pushing mechanism, the battery pack and the electrical connector can approach or move away from each other at the same time, improving the connection efficiency.

[0042] Preferably, a second stopping mechanism is arranged on the side of the battery compartment away from the electrical connector, for stopping the battery pack in the second direction perpendicular to the in-out direction, so as to keep the electrical connector electrically connected with the battery pack.

[0043] In the scheme, the second stopping mechanism is arranged to limit the movement of the battery pack away from the electrical connector during the connection of the electrical connector with the battery pack, avoiding the pushing force of the first pushing mechanism being too large to push the battery pack away, thereby facilitating the electrical connection of the electrical connector with the battery pack.

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

[0045] In the scheme, the battery charging rack is applied in the charging bin, which correspondingly reduces the time for the battery pack to transfer between the battery transfer device and the battery bin, improves the battery replacement efficiency, and can accurately adjust the position of the battery pack in the first direction, 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, so that the battery pack storage position is more accurate to facilitate the electrical connector to align in the first direction for charging.

[0046] A battery replacement station or energy storage station, comprising the charging bin as described above.

[0047] In the scheme, the battery charging rack is applied in the charging bin, which correspondingly reduces the time for the battery pack to transfer between the battery transfer device and the battery bin, improves the battery replacement efficiency, and can accurately adjust the position of the battery pack in the first direction, facilitates the connection between the electrical connector and the battery pack, and improves the connection efficiency.

[0048] On the basis of common sense in the art, the above-mentioned preferred conditions can be combined arbitrarily, that is, each preferred example of the present application is obtained.

[0049] The positive progress effect of the present application is that:

[0050] For the battery charging rack, the first speed-up chain displacement mechanism is provided, which can accurately adjust the position of the battery pack in the first direction. Since the electrical connector is usually arranged on the side surface of the battery bin, it is beneficial to align the battery pack with the electrical connector in the first direction, 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 transfer device to the battery bin, or drive the battery pack to move from the battery bin to the battery transfer device, thereby reducing the time for the battery pack to transfer between the battery transfer device and the battery bin, 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-up chain displacement mechanism can be changed, so that different models of battery packs can be located at the middle position or the preset position of the charging bin, thereby being suitable for adjusting battery packs of different sizes, and the universality of the charging bin is high.

[0081] The embodiment discloses a battery charging rack 100. As shown in Figures 1-5 The battery charging rack 100 comprises a plurality of vertically arranged battery compartments 1, each of which has a battery access port 104 for a battery transfer device 200 to store or take out a battery pack 300 from the battery charging rack 100, and each of which comprises two first speed-up chain displacement mechanisms 101 arranged in a first direction of the battery pack 300 and 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 the first speed-up chain displacement mechanisms 101 can be increased or reduced according to actual design requirements.

[0082] In the embodiment, the first speed-up chain displacement mechanisms 101 can drive the battery pack 300 to move from the battery transfer device 200 to the battery compartment 1 or to move from the battery compartment 1 to the battery transfer device 200, thereby reducing the time for the battery pack 300 to transfer between the battery transfer device 200 and the battery compartment 1 and improving the battery replacement efficiency. In addition, the first speed-up chain displacement mechanisms 101 can accurately adjust the position of the battery pack 300 in the first direction a1, which is beneficial to align the battery pack 300 with the electrical connector in the first direction a1 and facilitate the connection between the electrical connector and the battery pack 300. In addition, the first speed-up chain displacement mechanisms 101 adopt the speed-up chain structure, can select the running speed of the chain, and use the speed-up function of the speed-up chain, so that the battery pack 300 supported thereon can run quickly. The conveying speed is accurate and stable, and the battery pack 300 can be accurately conveyed. For different models of battery packs 300, especially for battery packs with different widths (corresponding to the first direction a1), the moving distance of the first speed-up chain displacement mechanisms 101 can be changed, so that different models of battery packs 300 can be located at the middle position or the preset position of the battery compartment 1, thereby being suitable for adjusting battery packs 300 with different sizes, and the battery compartment 1 has high universality.

[0083] It should be noted that, as shown in Figure 1 and Figure 3 The first direction a1 in the embodiment refers to the direction in which the battery pack 300 enters or exits. The first speed-up chain displacement mechanism 101 in the embodiment is based on the speed-up chain structure. The speed-up chain can refer to a material conveying machine taking the chain as a traction and carrying body, which belongs to a conveyor and can convey bulky articles at one time.

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

[0085] The battery compartment 1 can include a first stop mechanism (not shown) arranged at the side of the battery compartment 1 opposite to the battery inlet and outlet 104. The first stop mechanism is used to stop the battery in the 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 set by the operator in advance, which can accurately align the battery pack 300 with the electrical connector 106.

[0086] In a preferred embodiment, the first stop mechanism can be arranged to be movable in the first direction a1. By adjusting the position of the first stop mechanism in the first direction a1, the battery compartment 1 can store battery packs 300 of different sizes by adapting to battery packs 300 of different widths in the first direction.

[0087] In one embodiment, the first stop mechanism can include a driving part and a stopping part. The driving part is used to drive the stopping part to vertically ascend and descend. When the battery pack 300 enters, the driving part drives the stopping part to ascend to stop the battery pack 300. When there is no battery pack 300 entering or the battery pack 300 has been positioned, the driving part drives the stopping part to descend, thereby saving the space inside the battery compartment 1. In another embodiment, the first stop mechanism can only include the stopping part, which is vertically arranged at the side of the battery compartment 1 opposite to the battery inlet and outlet 104, regardless of whether the battery pack 300 enters or not.

[0088] The first stop mechanism can be provided with a sensor (not shown) in communication connection with the control unit of the first 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 speed chain displacement mechanism 101 to stop running. Wherein, the sensor is used to judge whether the battery pack 300 is in contact with the first stop mechanism, so as to detect whether the battery reaches the preset position. When the battery pack 300 is in contact with the first stop mechanism, the sensor can send a signal in time to make the control unit control the first speed chain displacement mechanism 101 to stop running in time. The sensor can be a limit switch, a proximity switch, etc., or other sensors with the same function.

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

[0090] The battery compartment 1 can also include a positioning mechanism (not shown) disposed on both sides of the battery compartment 1 adjacent to the battery inlet and outlet 104, which 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 placed more stably in the battery compartment 1.

[0091] The battery compartment 1 can also include a battery carrying part 103 disposed 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 for carrying the battery pack 300. By providing the battery carrying part 103, after the first speed chain displacement mechanism 101 moves the battery pack 300 to the preset position, the battery pack 300 can be carried only by the battery carrying part 103. In this case, the first speed chain displacement mechanism 101 is only used to adjust the position of the battery pack 300, thereby avoiding excessive wear of the first speed chain displacement mechanism 101, maintaining its accuracy during use, and improving its service life. The battery carrying part 103 includes a carrying plate and a connecting plate, and the carrying plate and the connecting plate form a frame structure. The frame structure not only ensures that the battery charging rack 100 is stable enough, but also reduces the weight of the battery carrying part 103.

[0092] It should be noted that in the present embodiment, the first speed chain displacement mechanism 101 is located on the inner side of the battery carrying portion 103, so that the placement position of the battery pack 300 on the battery carrying portion 103 is more balanced, and the stability of the battery pack 300 is improved. In other alternative embodiments, the first speed chain displacement mechanism 101 can also be arranged on the outer side of the battery carrying portion 103, or part of it is arranged on the outer side and part of it is arranged on the inner side, as long as they do not interfere with each other in the vertical direction.

[0093] It should be noted that in other alternative embodiments, the battery compartment 1 can also not be provided with a battery carrying portion 103, in which case the first speed chain displacement mechanism 101 simultaneously has the functions of adjusting the position of the battery pack 300 and carrying the battery pack 300, simplifying the structure of the entire battery compartment 1 and reducing the cost.

[0094] The battery compartment 1 can further comprise a first lifting mechanism (not shown) for moving the first speed chain displacement mechanism 101 in the vertical direction, the moving path of the first speed chain displacement mechanism 101 in the vertical direction having a first upper limit position and a first lower limit position;

[0095] 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 carrying surface 1031 in the vertical direction, so that the first speed chain displacement mechanism 101 drives the battery pack 300 to move in 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 carrying surface 1031 in the vertical direction, so that the battery carrying surface 1031 carries the battery pack 300.

[0096] By providing the first lifting mechanism, the switching of the battery pack 300 between the first speed chain displacement mechanism 101 and the battery carrying portion 103 is realized. When the battery pack 300 needs to be moved, the first lifting mechanism drives the first speed chain displacement mechanism 101 to rise, avoiding the interference of the battery carrying surface 1031 to 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 portion 103, thereby playing a role of protecting the first speed chain displacement mechanism 101.

[0097] The battery carrying part 103 can also include a plurality of balls 1032 arranged between the battery carrying part 103 and the contact surface of the battery pack 300, and the balls 1032 extend in the direction of the battery pack 300 or the first direction a1. By arranging the balls 1032, the battery pack 300 can also move 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 be raised to be higher than 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, which reduces the moving stroke of the first speed chain displacement mechanism 101 in the vertical direction, and has the effect of saving energy; in addition, when the battery contact surface is at the same height as the battery carrying surface 1031, the battery carrying part 103 can share part of the weight of the battery pack 300, thereby further avoiding wear of the first speed chain displacement mechanism 101.

[0098] The battery compartment 1 also includes an electrical connector 106 for connecting to the battery pack 300 to charge the battery pack 300, and the electrical connector 106 is arranged on either side of the battery compartment 1 adjacent to the battery inlet and outlet 104. The electrical connector 106 is arranged on the side of the battery compartment 1, which facilitates charging of the battery pack 300.

[0099] The battery compartment 1 also includes two second speed chain displacement mechanisms 107, which extend in the second direction a2 in the battery compartment 1, and are used to drive the battery pack 300 to move in the second direction a2 to enable the battery pack 300 to 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 second speed chain displacement mechanisms 107 can be increased or decreased according to actual design requirements.

[0100] The second speed chain displacement mechanism 107 is used to drive the battery pack 300 to move in the second direction, which on the one hand enables the battery pack 300 to move in a direction towards or away from the electrical connector 106, thereby facilitating accurate electrical connection or disconnection of the electrical connector 106 and the battery pack 300, and being suitable for different sizes of battery pack 300, especially battery pack 300 of different lengths in the second direction. On the other hand, when the battery transfer device 200 removes the battery pack 300 from the battery compartment 1, adjusting the position of the battery pack 300 in the second direction facilitates accurate cooperation of the extension part with the battery pack 300, thereby improving the battery replacement efficiency. In addition, for different models of battery packs, especially for battery packs 300 of different lengths (corresponding to the second direction), the moving distance of the second speed chain displacement mechanism 107 can be changed, so that battery packs 300 of different models can be located at the middle position or the 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 first speed chain displacement mechanisms 101 and second speed chain displacement mechanisms 107 can also be multiple, thereby increasing the contact area with the battery pack 300 and improving the stability of the battery pack 300 during movement.

[0102] The battery compartment 1 can also include a second lifting mechanism (not shown) for moving the second speed chain displacement mechanism 107 in the vertical direction, the movement path of the second speed chain displacement mechanism 107 in the vertical direction having 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 portion 103 provided on both sides of the battery compartment 1 adjacent to the battery inlet and outlet 104, the battery carrying portion 103 having a battery carrying surface 1031 for carrying the battery pack 300; the second speed chain displacement mechanism 107 is located inside the battery carrying portion 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 in 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 the second lifting mechanism, the switching of the battery pack 300 between the second speed chain displacement mechanism 107 and the battery carrying portion 103 is realized. When the battery pack 300 needs to be moved in the second direction, the second lifting mechanism drives the second speed chain displacement mechanism 107 to rise, avoiding interference of the battery carrying surface 1031 with the movement of the battery pack 300. When the battery pack 300 needs to be fixed, the second lifting mechanism drives the second speed chain displacement mechanism 107 to descend, and the battery pack 300 falls on the battery carrying portion 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 lifter lifting mechanism, a horizontal screw mechanical lifting mechanism, a hydraulic lifting mechanism, etc. The first lifting mechanism is provided at both ends or below the first speed chain displacement mechanism 101, and the second lifting mechanism is provided at both ends or below the second speed chain displacement mechanism 107, so that the lifting process of the first speed chain displacement mechanism 101 and the second speed chain displacement mechanism 107 is more stable.

[0106] The battery compartment 1 can further include a first pushing mechanism 109 located on the same side as the electrical connector 106, the first pushing mechanism 109 being configured to push the electrical connector 106 to move towards or away from the battery pack 300 to electrically connect or disconnect the electrical connector 106 with the battery pack 300. By providing the first pushing mechanism 109, the electrical connector 106 can be moved to electrically connect or disconnect 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 being arranged on the first pushing platform 1093, the first driving member 1091 providing a driving force to the first pushing member 1092 to push the electrical connector 106. The first driving member 1091 can be a driving mechanism such as a driving motor or a pneumatic cylinder, and the first pushing member 1092 can be a vertically arranged plate-shaped structure to increase the contact area with the electrical connector 106 and make the pushing process more stable.

[0108] The battery compartment 1 can further include a second pushing mechanism 110 located on the opposite side of the electrical connector 106, the second pushing mechanism 110 being configured to push the battery pack 300 to move towards 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 be moved in the second direction to electrically connect or disconnect 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 be simultaneously moved closer to or away from each other, 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 being arranged on the second pushing platform 1103, the second driving member 1101 providing a driving force to the second pushing member 1102 to push the battery pack 300. The second driving member 1101 can be a driving mechanism such as a driving motor or a pneumatic cylinder, and the second pushing member 1102 can be a vertically arranged plate-shaped structure to increase the contact area with the battery pack 300 and make the pushing process more stable.

[0110] It should be noted that in the present embodiment, the battery compartment 1 has both the first pushing mechanism 109 and the second pushing mechanism 110, and in other alternative embodiments, the battery compartment 1 can only have the first pushing mechanism 109 or the second pushing mechanism 110. When only the first pushing mechanism 109 is provided, compared to moving the battery pack 300, only moving the electrical connector 106 makes the stability of the battery pack 300 in the battery compartment 1 better.

[0111] The second stop mechanism (not shown) is arranged on the side of the battery compartment 1 away from the electrical connector 106, and is used to stop the battery pack 300 in the second direction a2 perpendicular to the in-out direction, so as to keep the electrical connector 106 electrically connected with the battery pack 300. By arranging the second stop mechanism, the movement of the battery pack 300 away from the electrical connector 106 can be limited during the connection of the electrical connector 106 and the battery pack 300, so as to avoid that the pushing force of the first pushing mechanism 109 is too large to push the battery pack 300 away, thereby facilitating the electrical connection between the electrical connector 106 and the battery pack 300.

[0112] The embodiment also discloses a charging compartment 400, which comprises the battery transfer device 200 and the battery charging rack 100 as above. The battery transfer device 200 is arranged on the side of the battery charging rack 100 having the battery in-out port, and is used to store or take out the battery pack 300 from the battery charging rack 100, so as to transfer the battery pack 300 between the battery compartments 1 arranged in the vertical direction of the battery charging rack 100 or between the battery charging rack 100 and the battery replacement area.

[0113] The application of the battery charging rack 100 in the charging compartment 400 correspondingly reduces the time for the battery pack 300 to transfer between the battery transfer 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, thereby facilitating the connection between the electrical connector and the battery pack 300 and improving the connection efficiency. At the same time, 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 to facilitate the electrical connector 106 to be aligned in the first direction for charging.

[0114] The embodiment also discloses a battery replacement station 600, which comprises the battery transfer device 200, a battery replacement device, a battery conveying device, a vehicle loading platform 500 and the battery charging rack 100 as above. The battery transfer device 200 is arranged on the side of the battery charging rack 100, and is used to store or take out the battery pack 300 from the battery charging rack 100. The battery pack 300 is transferred between the battery charging rack 100 and the battery replacement device by the battery conveying device. The vehicle loading platform 500 is used to load the electric vehicle. The battery replacement device is arranged below the vehicle loading platform 500, and is used to install the full battery pack 300 to the electric vehicle or to dismount the depleted battery pack 300 from the electric vehicle.

[0115] The application of the battery charging rack 100 in the battery swap station 600 correspondingly reduces the time for the battery pack 300 to transfer between the battery transfer device 200 and the battery compartment 1, thereby improving the battery swap efficiency, and the position of the battery pack 300 in the first direction can be accurately adjusted, facilitating the connection between the electrical connector and the battery pack 300, and improving the connection efficiency.

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