Description

Technical Field

[0001] This utility model relates to the field of vehicle battery swapping technology, and more specifically, to a battery swapping station. Background Technology

[0002] Vehicle battery swapping stations are service facilities used to quickly replace electric vehicle batteries to replenish electrical energy and replace traditional charging methods. At a battery swapping station, vehicles need to be parked in a designated swapping area before the battery is swapped; typically, only one swapping area is provided. Patent document CN113232551B discloses a battery swapping station, which includes a support platform, a driveway, a first detection element, a second detection element, a first charging / swapping assembly, and a second charging / swapping assembly. The driveway is located on the support platform for vehicle passage; both the first and second detection elements are used to detect the vehicle's position. The two charging / swapping assemblies are located on opposite sides of the driveway. Both the first and second charging / swapping assemblies include a charging component and a battery swapping robot. The charging component is used to charge the battery. The battery swapping robot of the first charging / swapping assembly is configured to transfer a fully charged battery to a third preset position to wait when the vehicle arrives at a first preset position, and to place a fully charged battery onto the vehicle after the vehicle arrives at a second preset position and the battery swapping robot of the second charging / swapping assembly removes the battery to be charged.

[0003] During peak battery swapping periods, because there is only one swapping area, subsequent vehicles must queue up and wait for the vehicle in front to complete its swap and leave before entering the swapping area. The swapping equipment can only remove the empty battery pack from the vehicle and begin swapping after the vehicle has parked at its designated swapping location. During the transition between vehicles, the swapping equipment experiences significant downtime, and this efficiency loss during the transition phase directly reduces the overall battery swapping efficiency.

[0037] With the rapid development of new energy vehicles, vehicle battery swapping stations, as a highly efficient energy replenishment facility, have replaced traditional charging methods to a certain extent by quickly replacing electric vehicle batteries. Currently, battery swapping stations generally adopt a fixed swapping model, meaning vehicles must be precisely parked in the swapping area before the swapping equipment performs battery removal, transfer, and installation. However, during peak swapping periods, because there is only one swapping area, subsequent vehicles must wait for the preceding vehicle to complete its swap and leave before entering the swapping area. During the transition between vehicles, the swapping equipment experiences significant idle periods, and this efficiency loss during these transition phases directly reduces the overall swapping efficiency. Optimizing the layout of battery swapping stations to shorten idle periods and improve swapping efficiency has become a pressing technical challenge.

[0038] This embodiment provides a battery swapping station, such as Figure 1As shown, the battery swapping station may include a frame assembly 10, a charging assembly 20, a handling assembly 30, and a control assembly. The frame assembly 10 may include a charging frame unit 11, a first battery swapping frame unit 12, and a second battery swapping frame unit 13. The charging frame unit 11 can form a hollow cavity; the first battery swapping frame unit 12 can form a hollow cavity; and the second battery swapping frame unit 13 can form a hollow cavity. The first battery swapping frame unit 12, the charging frame unit 11, and the second battery swapping frame unit 13 can be connected sequentially along a first direction. The hollow cavities formed by the first battery swapping frame unit 12, the charging frame unit 11, and the second battery swapping frame unit 13 can be connected sequentially along the first direction. This structure forms a continuous working space through the connection of three independent cavities, realizing modular layout and functional zoning of equipment, and providing a foundation for the parallel operation of dual battery swapping areas.

[0039] The charging assembly 20 can be installed in the hollow cavity enclosed by the charging frame unit 11. This arrangement utilizes the central cavity to centrally manage charging resources, and the charging assembly 20 can enter the first frame unit or the second frame unit from two directions, so that the vehicle can be swapped while parked in either the first frame unit or the second frame unit.

[0040] The handling component 30 can be connected to the charging frame unit 11. The handling component 30 can handle the charging component 20, enabling operations such as removing the empty battery box 23, transporting and installing the fully charged battery box 23.

[0041] The control component can be electrically connected to the charging component 20; the control component can also be electrically connected to the transport component 30. The control component can sense the arrival of vehicles and the status of the battery box 23 in the battery swapping station, thereby controlling the transport component 30 to perform battery swapping.

[0042] The battery swapping station can include an operational state and an idle state. In the operational state, a transport assembly 30 and a portion of the charging assembly 20 may be detachably connected. The transport assembly 30 can transport at least a portion of the charging assembly 20, i.e., the battery box 23, to the hollow cavity enclosed by the first battery swapping frame unit 12 or the hollow cavity enclosed by the second battery swapping frame unit 13 for battery swapping. In the idle state, the transport assembly 30 and the charging assembly 20 may be spaced apart, and the transport assembly 30 may retract into the hollow cavity enclosed by the charging frame unit 11.

[0043] In operation, the transport component 30 can flexibly transport the charging component 20 to different battery swapping areas. Thus, when the first battery swapping vehicle in the first battery swapping frame unit 12 has swapped its battery but has not yet left, the transport component 30 can swap the battery of the second battery swapping vehicle that has been parked in the second battery swapping frame unit 13 in advance, thereby maximizing efficiency. In idle state, the transport component 30 retracts to save space, reduce unnecessary energy consumption, rationally arrange the operating status of each component of the battery swapping station, and improve the overall operating efficiency of the battery swapping station.

[0044] In this embodiment, as Figure 1 As shown, the charging assembly 20 may include a charger 21, a charging base 22, and a battery box 23. The charging base 22 and the battery box 23 can be detachably connected. The battery box 23 can be electrically connected to the charger 21 via the charging base 22. The charging base 22 can be connected to the charging frame unit 11. The charger 21 can be connected to the charging frame unit 11. The charger 21 can be electrically connected to a control component, so that the control component can control the charger 21 to charge the battery box 23 when it is not fully charged. This detachable connection structure can achieve electrical connection stability through the charging base 22, and together with the power management of the control component, it forms a standardized charging unit. In some embodiments, there may be multiple battery boxes 23, evenly distributed in the hollow cavity enclosed by the charging frame unit 11, and there may also be multiple corresponding charging bases 22 and chargers 21.

[0045] In this embodiment, as Figure 1 As shown, the charging frame unit 11 may include an upper frame 111 and a lower frame 112. The upper frame 111 can be connected to the lower frame 112. The upper frame 111 can form a hollow cavity, and the lower frame 112 can form a hollow cavity. The hollow cavities formed by the first battery swapping frame unit 12, the upper frame 111, and the second battery swapping frame unit 13 can be sequentially connected along a first direction. The charging base 22 can be connected to the upper frame 111, and the battery box 23 can be disposed in the hollow cavity formed by the upper frame 111. The charger 21 can be connected to the lower frame 112, and the charger 21 can be disposed in the hollow cavity formed by the lower frame 112. By separating battery storage and charging equipment through a hierarchical layout, the upper frame 111 cavity provides battery storage space, and the lower frame 112 cavity bears the weight of the charger 21 and isolates the heat dissipation effect, thus realizing the functional zoning and space optimization of the charging frame unit 11. In some other embodiments, the charger 21 may also be located in the space outside the lower frame 112, which facilitates heat dissipation of the battery box 23 inside the charging frame unit 11.

[0046] In this embodiment, as Figure 1 As shown, the charging frame unit 11 may further include a first battery swapping door 113 and a second battery swapping door 114. The first battery swapping door 113 can be connected to the upper frame 111, and the second battery swapping door 114 can be connected to the upper frame 111. The first battery swapping door 113 can be electrically connected to the control component, and the second battery swapping door 114 can be electrically connected to the control component. This gate control structure establishes the boundary of the battery swapping area, and at the same time, the control component realizes the gate status control, which can control the opening of the first battery swapping door 113 or the second battery swapping door 114 when a battery swapping operation is required.

[0047] The working state can include opening either the first battery swapping door 113 or the second battery swapping door 114, allowing the transport assembly 30 to transport the battery box 23 through the first battery swapping door 113 into the hollow cavity enclosed by the first battery swapping frame unit 12, or the transport assembly 30 to transport the battery box 23 through the second battery swapping door 114 into the hollow cavity enclosed by the second battery swapping frame unit 13, thereby swapping batteries for vehicles parked in the first battery swapping frame unit 12 or the second battery swapping frame unit 13. The idle state can include closing the first battery swapping door 113 and the second battery swapping door 114, isolating the upper frame 111 from the first battery swapping frame unit 12, and isolating the upper frame 111 from the second battery swapping frame unit 13. The opening and closing of the doors controls whether the battery transport path is connected or not; in the working state, the battery swapping channel is open, and in the idle state, the battery box 23 is sealed and protected.

[0048] In this embodiment, as Figure 2 As shown, the transport assembly 30 may include a trolley unit 31 and a trolley unit 32. The trolley unit 31 may include a trolley guide rail 311 and a trolley drive unit 312. The trolley guide rail 311 may be connected to the upper frame 111, and the trolley drive unit 312 may be connected to the trolley guide rail 311. The trolley guide rail 311 may extend along a second direction. The trolley unit 32 may be movably connected to the trolley guide rail 311. A control assembly may be electrically connected to the trolley drive unit 312. The second direction may be perpendicular to the first direction on a horizontal plane.

[0049] The working state can include the connection between the trolley unit 32 and the battery box 23, and the trolley drive unit 312 can drive the trolley unit 32 to move on the trolley guide rail 311. The position of the trolley unit 32 in the width direction of the battery swapping station can be adjusted by moving in the second direction, providing a displacement basis for multi-station operations.

[0050] In this embodiment, as Figure 2 As shown, the trolley unit 32 may include a first guide rail 321, a first drive unit 322, a second guide rail 323, a second drive unit 324, and a trolley body 325. The first guide rail 321 and the first drive unit 322 can be connected, and the second guide rail 323 and the second drive unit 324 can be connected. The first guide rail 321 and the second guide rail 323 can be slidably connected; the trolley body 325 and the second guide rail 323 can be slidably connected; the first guide rail 321 and the main trolley guide rail 311 can be slidably connected. The control component can be electrically connected to the first drive unit 322; the control component can be electrically connected to the second drive unit 324. This nested double guide rail structure forms a composite motion mechanism, with the first guide rail 321 providing a primary displacement track and the second guide rail 323 achieving secondary precise positioning.

[0051] The working state can include the connection between the trolley body 325 and the battery box 23. The second drive unit 324 drives the trolley body 325 to slide along the second guide rail 323 in a first direction, and / or the first drive unit 322 can drive the second guide rail 323 to slide along the first guide rail 321 in a first direction, and / or the trolley drive unit 312 can drive the first guide rail 321 to slide along the trolley guide rail 311 in a second direction. Through multi-level linkage, the trolley body 325 can be precisely positioned in the length direction of the battery swapping station. Combined with the movement of the trolley unit 32 on the trolley guide rail 311, the trolley body 325 can be positioned in the width direction of the battery swapping station. It can be accurately moved to any position of the battery box 23 within the charging frame unit 11 to realize the battery swapping operation.

[0052] In this embodiment, as Figure 3 As shown, the vehicle unit 32 may further include a gripping unit 326. The gripping unit 326 may include a gripping body 3261, a positioning part 3262, a gripping part 3263, a gripping drive part, and a vertical drive part. The gripping body 3261 may be connected to the positioning part 3262, and the positioning part 3262 may protrude from the gripping body 3261 on the side near the battery box 23, thereby enabling precise positioning when gripping the battery box 23. The gripping body 3261 and the gripping part 3263 may be movably connected. The gripping drive part and the gripping part 3263 may be connected. The vertical drive part may be connected to the gripping body 3261; the control component may be electrically connected to the gripping drive part. The control component may be electrically connected to the vertical drive part; the gripping body 3261 and the vehicle body 325 may be movably connected. The control component can control the vertical drive unit to move the gripping body 3261 in the vertical direction to approach the battery box 23; the control component can control the gripping drive unit to perform a gripping action on the battery box 23.

[0053] The working state may include the vertical drive unit driving the gripping body 3261 to move vertically, and / or the gripping drive unit driving the gripping part 3263 to grip the battery box 23. By adjusting the gripping height through vertical displacement to match the position of the battery box 23, and controlling the gripping part 3263 to complete the gripping action, the precise gripping and release of the battery box 23 can be achieved.

[0054] In this embodiment, as Figure 1 As shown, the battery swapping station may also include a fire-fighting component 40, which may include a first fire-fighting unit 41. The first fire-fighting unit 41 may be located in the first battery swapping frame unit 12, so that in the event of an accident in the battery swapping station, the faulty battery box 23 can be transferred to the first fire-fighting unit 41 in a timely manner to implement fire-fighting measures, and then the battery swapping vehicle can be swapped normally in the second battery swapping frame unit 13, ensuring that the battery swapping station still has the ability to swap batteries in the event of an accident and improving the overall battery swapping efficiency.

[0055] The first fire-fighting unit 41 may include a first fire pool 411, a first shielding door 412, and a first fire-fighting actuator. The first fire pool 411 and the first shielding door 412 may be movably connected. The first fire-fighting actuator and the first shielding door 412 may be connected. The first fire-fighting actuator and the control components may be electrically connected. The first fire pool 411 may be recessed relative to the bottom surface of the charging frame unit 11. The top of the first shielding door 412 may be on the same plane as the bottom surface of the charging frame unit 11. The first fire pool 411 and the first shielding door 412 may form a closed fire-fighting space, and the flush design maintains the flatness of the ground.

[0056] The battery swapping station can be in a fire-fighting state and a battery swapping state. In the fire-fighting state, the first shielding door 412 may be open, and the transport assembly 30 may move some of the charging components 20 into the first fire-fighting pool 411. In the battery swapping state, the first shielding door 412 may be closed, and the first shielding door 412 and the first fire-fighting pool 411 may form a sealed space. Fire isolation is achieved through state switching; while fire-fighting operations are being carried out in one battery swapping area, normal battery swapping operations continue in the other area, improving overall battery swapping efficiency.

[0057] In this embodiment, as Figure 1 As shown, the fire-fighting component 40 may also include a second fire-fighting unit 42. The second fire-fighting unit 42 may be installed in the second battery swapping frame unit 13, so that when a vehicle is swapping batteries in the first battery swapping frame unit 12, the second fire-fighting unit 42 in the second battery swapping frame unit 13 can be used directly for fire-fighting operations without having to stop the battery swapping operations in the first battery swapping frame unit 12.

[0058] The second fire-fighting unit 42 may include a second fire pool 421, a second shielding door 422, and a second fire-fighting actuator. The second fire pool 421 and the second shielding door 422 may be movably connected. The second fire-fighting actuator and the second shielding door 422 may be electrically connected. The second fire-fighting actuator and a control assembly may be electrically connected. The second fire pool 421 may be recessed relative to the ground of the charging frame unit 11. The top of the second shielding door 422 may be on the same plane as the bottom surface of the charging frame unit 11.

[0059] In fire-fighting mode, the first shielding door 412 may be opened, and the transport assembly 30 may transport a portion of the charging assembly 20 to the first fire pool 411; or the second shielding door 422 may be opened, and the transport assembly 30 may transport a portion of the charging assembly 20 to the second fire pool 421. In power-swapping mode, the first shielding door 412 may be closed, forming a sealed space with the first shielding door 412 and the first fire pool 411; and the second shielding door 422 may be closed, forming a sealed space with the second shielding door 422 and the second fire pool 421. The first fire-fighting unit 41 and the second fire-fighting unit 42, respectively located in the two power-swapping areas, ensure that even if one power-swapping area is occupied, the fire-fighting assembly 40 in the other power-swapping area can still maintain fire-fighting functionality.

[0060] In this embodiment, as Figure 4 As shown, some charging bases 22 can be connected to the upper frame 111, and the remaining charging bases 22 can be connected to the lower frame 112. Some battery boxes 23 can be placed in the hollow cavity enclosed by the upper frame 111, and the remaining battery boxes 23 can be placed in the hollow cavity enclosed by the lower frame 112, thereby maximizing the use of the internal space of the battery swapping station and accommodating more battery boxes 23 to improve the battery swapping efficiency of the station. The battery boxes 23 can be electrically connected to the charging bases 22. The battery boxes 23 in the upper frame 111 are arranged in two rows, with a battery swapping channel between the two rows of battery boxes 23, which can prevent shaking and collision with adjacent rows of battery boxes 23 when removing the battery boxes 23. The battery boxes 23 in the lower frame 112 are arranged in one row, and the vertical projection of the battery boxes 23 in the lower frame 112 lies between the vertical projections of the two rows of battery boxes 23 in the upper frame 111, so that the transport component 30 does not need to move the position of the battery boxes 23 when grabbing them, and can be directly hoisted. The battery box 23 in the upper frame 111 is vertically closer to the transport component 30, and can be transported to the first battery swapping gate 113 or the second battery swapping gate 114 at a faster speed. Therefore, setting two rows of battery boxes 23 in the upper frame 111 and one row in the lower frame 112 can improve the overall battery swapping efficiency of the battery swapping station.

[0061] In other embodiments, such as Figure 1 As shown, the charging frame unit 11 may include a dustproof plate (not shown in the figure). The dustproof plate can be connected to the upper frame 111. When the first battery swapping door 113 and the second battery swapping door 114 are closed, the dustproof plate, the charging frame, the first battery swapping door 113, and the second battery swapping door 114 can together form a closed space. By forming a dustproof barrier through the coordinated sealing of multiple components, external contaminants are effectively prevented from entering the battery storage area during non-working periods.

[0062] Those skilled in the art will understand that the above embodiments are specific examples of implementing this disclosure, and in practical applications, various changes can be made in form and detail without departing from the scope of this disclosure.
