However, all descriptions should not be construed as limiting the present utility model in any way.

[0033] Furthermore, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in the various drawings, the present invention still allows for any combination or deletion of these technical features (or their equivalents) without any technical obstacle. Therefore, these further embodiments according to the present invention should also be considered within the scope of the description herein.

[0034] It should also be noted that the terms “inner,” “outer,” “upper,” “lower,” etc., indicate the orientation or positional relationship based on the orientation or positional relationship of the battery compartment and the battery swapping station including it shown in the accompanying drawings. They are only for the convenience of describing this disclosure and simplifying the description, and are not intended to indicate or imply that the device or component referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this disclosure.

[0035] Furthermore, the terms "first" and "second" are used for descriptive purposes only and should not be construed as indicating or implying relative importance or implicitly specifying the number of technical features indicated. Thus, a feature defined with "first" or "second" may explicitly or implicitly include at least one of that feature.

[0036] In the description of this disclosure, "multiple" means at least two, such as two, three or more, unless otherwise expressly and specifically limited.

[0037] from Figure 1 As can be seen, the battery swapping station 9 of this utility model includes a vehicle swapping station 8 for parking vehicles waiting to be swapped, and battery compartments 1 located on both sides of the vehicle swapping station 8. The battery compartments 1 include a lifting device 7 and battery racks 13 respectively located on both sides of the lifting device 7. The lifting device 7 is used to transport the batteries removed from the vehicle to the battery racks 13, and to transport the fully charged batteries on the battery racks 13 to the vehicle, so as to complete the replacement of the vehicle battery.

[0038] It should be noted that in this embodiment, each battery rack 13 includes several sub-battery racks 131 arranged side by side. The connection method between these sub-battery racks 131 is not limited; it can be a detachable connection method such as a pin connection or a bolt connection, allowing for convenient and quick increases or decreases in the number of sub-battery racks 131 in each battery rack 13. The arrangement of the sub-battery racks 131 in each battery rack 13 can be as follows: Figure 1 As shown in the embodiment, the battery racks 13 are arranged along their length, which is also the length of the vehicle. Two battery racks 13 are arranged side by side on both sides of the lifting device 7 along their length, and the sum of the lengths of the two battery racks 13 and the lifting device 7 is less than or equal to the longitudinal length of the vehicle's power exchange 8. In other embodiments, each battery rack 13 may also include several rows of battery racks arranged laterally, i.e., in the width direction of the vehicle.

[0039] Optionally, the number of sub-cell holders 131 in each cell holder 13 is unlimited, and can be as follows: Figure 1 The two shown can also be one or more. The number of sub-battery racks 131 can be increased or decreased according to the actual capacity of the battery swapping station 9.

[0040] Specifically, such as Figure 2 As shown, the sub-battery rack 131 is formed by multiple horizontal and vertical support rods, creating multiple battery storage compartments 12. Each battery storage compartment 12 is open towards the lifting device 7 (e.g., Figure 1 As shown), each battery storage unit 12 is equipped with a transmission device 2, which enables the battery storage units 12 on the same floor of the side-by-side sub-battery racks 131 to transfer batteries to each other.

[0041] Furthermore, the battery compartments 12 in the sub-battery rack 131 can have different specifications to store batteries of different specifications, thereby meeting the battery swapping needs of more types of vehicles.

[0042] Optionally, as shown in the figure, the transmission devices 2 can be respectively installed on both sides of the battery compartment 12, that is, the middle of the battery compartment 12 is hollowed out, so that maintenance personnel can inspect and repair the various components of the battery rack 13 through the hollowed-out area. When the battery is placed in the battery compartment 12, the two sides of the battery are located on the transmission devices 2 on both sides.

[0043] Combination Figure 3 As can be seen, the transmission device 2 includes multiple rollers 24 evenly distributed from one end of the battery storage compartment 12 to the other end, a conveyor belt 23 connecting the multiple rollers 24, a drive motor 21, and a drive shaft 22 connecting the drive motor 21 to the main roller of the rollers 24. The drive motor 21 is fixed on the transverse support rod on the outside of the roller 24, so as not to hinder the placement and transmission of batteries.

[0044] When the transmission devices 2 are respectively located on both sides of the battery storage compartment 12, the two ends of the drive shaft 22 are respectively connected to the main rollers of the two transmission devices 2, and the batteries placed in the battery storage compartment 12 are located on the rollers 24 of the two transmission devices 2. It can be understood that in other embodiments, each of the two main rollers may be provided with a drive shaft 22 and a drive motor 21.

[0045] In use, the drive motor 21 of the transmission device 2 drives the main roller to rotate via the drive shaft 22. The main roller drives other rollers 24 to rotate via the conveyor belt 23, so as to move the batteries located on the rollers 24 to the end of the battery storage position 12.

[0046] Thus, the transmission device 2 can receive batteries from the lifting device 7, and can also transfer batteries from the battery rack 13 to the lifting device 7. Furthermore, the transmission device 2 can transfer batteries between the battery racks 13 arranged side by side.

[0047] Furthermore, from Figure 4 As can be seen, a side limiting device 6 and an elastic limiting member 4 near the end of the battery compartment 12 can be provided on the outer edge support rod 14 of each battery compartment 12, and a charging rack 11 can be provided on the upper support rod of each battery compartment 12. The charging rack 11 is used to install charging equipment to charge the batteries in the battery compartment 12.

[0048] Combination Figure 5As can be seen, the inner side of the area enclosed by the overlapping support rods of the battery rack 13 includes a first mounting base 62 disposed on the edge support rod 14, a first wheel mounting frame 63 mounted on the first mounting base 62, and a first guide wheel 61 disposed inside the first wheel mounting frame 63. The first wheel mounting frame 63 is roughly U-shaped, and the first guide wheel 61 is mounted inside the U-shaped structure.

[0049] according to Figure 5 In one embodiment, the first mounting base 62 is L-shaped, and the L-shaped first mounting base 62 has a base plate 64 and side plates 65. The base plate 64 is fixed to the edge support rod 14. The first wheel mounting frame 63 is disposed between the side plates 65 of the two first mounting bases 62, and the opening of the U-shaped structure of the first wheel mounting frame 63 faces the inner roller 24 (e.g., Figure 6 (As shown).

[0050] The top and bottom surfaces of the first wheel mounting frame 63 are provided with the axle of the first guide wheel 61 (not shown in the figure). The axle is evenly arranged along the length of the first wheel mounting frame 63. Multiple first guide wheels 61 are correspondingly arranged on multiple axles, and the first guide wheels 61 protrude inward toward the inner roller 24. When the battery passes through the roller 24, the side wall of the battery moves against the first guide wheel 61, so that the first guide wheel 61 can laterally limit the battery from both sides. This can prevent the battery from sliding out of the battery rack 13 when it moves, and also ensure that when the battery is placed in the battery storage position 12, its charging port can be aligned with the charging device.

[0051] Combination Figure 7 and Figure 8 It can be clearly seen that the elastic limiting member 4 is located on at least one side of the side limiting device 6 along the direction of battery movement. The elastic limiting member 4 and the side limiting device 6 can be located on the same edge support rod 14. The elastic limiting member 4 includes a second mounting base 5 fixed to the edge support rod 14, a lever arm 53 pivotally connected to the second mounting base 5, a second guide wheel 41 provided at the end of the lever arm 53, and an elastic member 42 (e.g., ...) provided inside the second mounting base 5 and sleeved outside the lever arm 53. Figure 8 (as shown), and the support rod 43 that is close to the elastic member 42 and abuts against the lever arm 53.

[0052] Specifically, as shown in the figure, the second mounting base 5 is provided with a first mounting member 51 and a second mounting member 52. The second mounting base 5, the first mounting member 51, and the second mounting member 52 can all be L-shaped plates. The bottom panel of the L-shaped plate of the second mounting base 5 is fixedly connected to the battery holder 13 (e.g., ...). Figure 4 As shown), the area enclosed by the support rod of the battery rack 13 is the inner side 15, and the area formed by the side panel and bottom panel of the L-shaped plate faces the inner side 15.

[0053] The L-shaped plate of the second mounting base 5 has an inner side facing inward 15. A first mounting member 51 is installed near the top of the inner side of the second mounting base 5, and a second mounting member 52 is installed near the bottom of the inner side of the second mounting base 5. One panel of the L-shaped plate of the first mounting member 51 is installed on the second mounting base 5, and the other panel is a top panel 44. The top panel 44 is located at the top of the area formed by the L-shaped plate of the second mounting base 5 and protrudes inward 15.

[0054] The second mounting member 52 has the same shape and structure as the first mounting member 51, and is disposed opposite to the first mounting member 51. The second mounting member 52 also has a bottom panel 45. Thus, the first mounting member 51, the second mounting member 52, and the second mounting base 5 enclose an installation space 46 (e.g., ...). Figure 8 (As shown).

[0055] The mounting space 46 is provided with a mounting shaft 58. The two ends of the mounting shaft 58 are fixed to the top panel 44 and the bottom panel 45 respectively, and an elastic element 42 is sleeved on the outer periphery of the mounting shaft 58.

[0056] Lever arm 53 has a central portion 55 mounted in the mounting space 46 (e.g., Figure 7 (as shown), a wheel mounting portion 54 extending from the center portion 55 toward the second guide wheel 41, and a rod portion 56 extending from the center portion 55 toward a direction away from the second guide wheel 41.

[0057] Specifically, the central part 55 is provided with an upper panel 47 and a lower panel 48 (e.g., Figure 8 As shown, the upper panel 47 is close to the top panel 44 of the first mounting member 51, and the lower panel 48 is close to the bottom panel 45 of the second mounting member 52. The mounting shaft 58 passes through the top panel 44, upper panel 47, lower panel 48, and bottom panel 45 in sequence, mounting the center part 55 in the mounting space 46. The elastic member 42 is a torsion spring, with one end abutting against the inner side of the second mounting base 5, and the other end abutting against the center part 55 of the lever arm 53.

[0058] like Figure 7 As shown, the upper panel 47 and lower panel 48 of the central part 55 extend toward the second guide wheel 41 to form a wheel mounting part 54. The end of the wheel mounting part 54 is provided with a shaft 57. The two ends of the shaft 57 are fixedly connected to the upper panel 47 and the lower panel 48 respectively, and the second guide wheel 41 is sleeved on the outer periphery of the shaft 57, that is, the second guide wheel 41 can rotate about the shaft 57 as the central axis.

[0059] The width of the lever arm 53's rod portion 56 can be smaller than the width of the center portion 55, and the end of the rod portion 56 extends into the mounting space 46.

[0060] Figure 7 and Figure 8The diagram shows the positions of the components of the elastic limiting member 4 in its normal state. The wheel mounting portion 54 protrudes inward 15 towards the battery compartment 12, while the rod portion 56 extends towards the side panel of the second mounting base 5 and abuts against it. The support rod 43 can be a screw, and its length extending into the mounting space 46 can be adjusted by turning the screw. This adjusts the distance between the contact point of the lever arm 53 and the support rod 43 and the side panel of the second mounting base 5. Combined with the abutment of the rod portion 56 against the second mounting base 5, the tilt angle of the lever arm 53 relative to the second mounting base 5 can be adjusted, thereby adjusting the depth of the second guide wheel 41 protruding into the battery compartment 12. This allows the second guide wheel 41 to abut against both sides of the battery, thus adjusting and limiting the battery.

[0061] When the battery is in battery compartment 12, the two sides of the battery contact the second guide wheel 41, causing the second guide wheel 41 to shift outwards. This causes the lever arm 53 to apply pressure to the elastic element 42, which generates elastic force. This force is transmitted back to the second guide wheel 41 through the lever arm 53, causing the second guide wheel 41 to apply force to both sides of the battery. This ensures that the battery is always located in the middle of battery compartment 12 and prevents it from shifting.

[0062] Combination Figure 2 and Figure 9 It can be seen that the battery storage compartment 12 is provided with an end limiting device 3 at its end. The end limiting device 3 is located at the upper or lower support rod at the end of the battery storage compartment 12. The end limiting device 3 is used to limit the two ends of the battery located in the battery storage compartment 12, so as to cooperate with the side limiting device 6 to limit the battery in the battery storage compartment 12, so that its charging port can be aligned with the charging equipment.

[0063] Specifically, the end limiting device 3 includes a movable limiting member 31 and a limiting block 32 located at one end of the battery storage compartment 12, and a stop bar 33 located at the other end of the battery storage compartment 12 (e.g., Figure 2 As shown), the stop bar 33 can be fixedly installed at the end of the battery compartment 12 of the sub-battery rack 131 furthest from the lifting device 7, so as to abut the end of the battery. From Figure 2As can be seen, the stop bar 33 extends from the top to the bottom of the sub-battery rack 131, intersecting with the support rod at the end of the sub-battery rack 131, so that each battery compartment 12 arranged along the height direction of the sub-battery rack 131 has a stop bar 33 at its end. The stop bar 33 is used to limit the end of the battery located in the battery compartment 12 at the end of the sub-battery rack 131, and together with the side limiting device 6, fixes the battery in the battery compartment 12 and aligns the battery charging port with the charging device. In other embodiments, an independent stop bar 33 can also be provided at the end of each battery compartment 12, so that the corresponding stop bar 33 can be lowered when needed. The raising and lowering of the stop bar 33 can be operated manually or controlled by a control device. When controlled by a control device, a drive element (e.g., a motor) can be provided at one end of the stop bar 33, and the drive element can be used to drive the stop bar 33 to raise or lower.

[0064] from Figure 10 As can be seen, the movable limiting component 31 has a mounting plate 36. One end of the mounting plate 36 is equipped with a motor 34. The motor 34 is fixed to the upper support rod of the battery compartment 12, and its output shaft is connected to the mounting plate 36, enabling it to drive the mounting plate 36 to rotate. Specifically, the output shaft of the motor 34 can be welded to the mounting plate 36, or the cross-section of the motor 34's output shaft can be non-circular, and the output shaft can be inserted into the corresponding mounting hole on the mounting plate 36. The other end of the mounting plate 36 has a protruding battery limiting part 35. The shape of the battery limiting part 35 matches the shape of the positioning groove at the end of the battery, so that the battery limiting part 35 can be engaged in the positioning groove at the end of the battery to fix and limit the position of the battery. Figure 10 It can also be seen that the mounting plate 36 may be provided with reinforcing plates extending along its length on both sides to enhance the strength of the mounting plate 36.

[0065] Figure 9 As shown in the figure, when the movable limiting member 31 is in the retracted position, the battery limiting part 35 of the mounting plate 36 is placed parallel to the upper support rod of the battery compartment 12. When the battery limiting part 35 is retracted, the battery can enter the interior of the battery compartment 12 through the end of the battery compartment 12, or enter the battery compartment 12 on the same layer next to it through the battery compartment 12.

[0066] Figure 11As shown in the figure, when the movable limiting member 31 is in the blocking position, when the battery is stored in the corresponding battery compartment 12, the motor 34 is started, causing the movable limiting member 31 to rotate around the output shaft of the motor 34, lowering the battery limiting part 35, so that the mounting plate 36 is perpendicular to the upper support rod of the battery compartment 12. The battery limiting part 35 can be inserted into the positioning groove at the end of the battery to abut against the battery, thereby restricting the storage position and posture of the battery from the end, so that the battery can be stored more stably in the battery compartment 12.

[0067] The working principle of the battery compartment of this utility model is as follows: The lifting device 7 of the battery compartment is used to lift the battery removed from the vehicle to be swapped to the battery storage space 12 to be stored. Then, it is transferred between the battery storage spaces 12 arranged side by side by the transmission device 2. During the transfer, the side limiting device 6 limits the battery from both sides to straighten the battery and prevent the battery from shifting.

[0068] When the battery is transferred to the corresponding battery storage location 12, the side limiting device 6 and the end limiting device 3 restrict the storage position of the battery from both sides and the end, respectively, so that the charging port of the battery is aligned with the charging equipment for charging.

[0069] Next, the lifting device 7 is raised to the height of the battery compartment 12 where the fully charged battery is located. After the battery is transferred from the battery compartment 12 to the lifting device 7 via the transmission device 2, the lifting device 7 transfers the fully charged battery to the vehicle swapping device 8 to complete the battery swapping operation.

[0070] The battery compartment of this invention features side-by-side sub-battery racks 131 that are closely fitted together, resulting in a compact structure that maximizes battery storage space within the battery swapping station 9 to meet the charging needs of more vehicles. Furthermore, multiple battery racks 13 share a single lifting device 7, reducing the battery compartment's footprint and lowering costs. The side-by-side sub-battery racks 131 are also equipped with a transmission device 2, which is integrated with the battery storage compartments 12 to facilitate battery transfer and storage between compartments on the same level.

[0071] This utility model also provides a battery swapping station 9, which has all the features of the aforementioned battery compartment 1, and therefore also has its corresponding advantages.

[0072] The technical scope of this utility model is not limited to the contents of the above description. Those skilled in the art can make various modifications and variations to the above embodiments without departing from the technical concept of this utility model, and all such modifications and variations should fall within the scope of this utility model.
