Description

TECHNICAL FIELD

[0001] The application belongs to the technical field of vehicle battery replacement, and particularly relates to a battery replacement device and a battery replacement station. BACKGROUND

[0002] Compared with traditional fuel vehicles, electric vehicles have the advantages of green environmental protection and high intelligence, and are of great significance to energy saving and emission reduction and urban traffic intelligence, and therefore gradually become the strategic development direction of future automobile industry.

[0003] The existing charging mode of electric vehicles is generally divided into two types of battery replacement and direct charging. In the prior art, a corresponding battery replacement station is built for the above-mentioned electric vehicles with battery replacement, and a user drives to the battery replacement station to replace the battery when the battery needs to be replaced. Since electric vehicles are various in types, the corresponding battery models, i.e. battery styles, are also different, so that the battery packs have different lengths or widths. In order to enable the battery replacement station to replace the batteries of various electric vehicles, some battery replacement stations are provided with multiple battery replacement positions and battery replacement devices to adapt to different forms of battery packs. The battery replacement device usually includes a battery replacement trolley that walks along a preset path to transfer the battery pack. The battery replacement trolley is usually provided with a battery replacement platform for unlocking and carrying the battery pack, and the battery pack is transferred by being carried by the battery replacement platform. In order to improve the battery replacement efficiency, multiple battery replacement trolleys are required to disassemble and install the battery pack, so as to avoid that the vehicle waits for a long time at the battery replacement position. On the one hand, since the battery replacement trolley has many components and a complex structure, increasing the number of battery replacement trolleys will increase the battery replacement cost. On the other hand, since the battery replacement trolley is provided with the battery replacement platform, when the walking of the battery replacement trolley or the unlocking of the battery replacement platform fails, the whole battery replacement trolley cannot be used, and the after-sales and maintenance costs are high and difficult. UTILITY MODEL CONTENTS

[0004] The application provides a battery replacement device and a battery replacement station, which improve the battery replacement efficiency of the battery replacement station and reduce the battery replacement cost by arranging a split type transport trolley and a battery replacement platform.

[0005] The technical scheme adopted by the application is as follows:

[0006] A battery replacement device for disassembling and transporting a battery to be replaced during battery replacement, the battery replacement device comprising:

[0007] A battery replacement platform for removing and installing the battery to be replaced;

[0008] A transport trolley for carrying the battery to be replaced for transfer, the transport trolley being provided with a first avoiding opening through which the battery replacement platform passes, and the battery replacement platform moving up and down relative to the transport trolley through the first avoiding opening to realize the interactive connection of the battery to be replaced between the battery replacement platform and the transport trolley.

[0009] The battery replacement device of the scheme is used for replacing the battery of an electric vehicle. After the vehicle to be replaced is parked and positioned above the battery replacement platform, the battery replacement platform is raised to disassemble the battery pack of the electric vehicle. After the battery replacement platform completes the disassembly of the depleted battery pack, the battery replacement platform drives the depleted battery pack to descend to contact the transport trolley. Then, the battery replacement platform continues to descend, so that the depleted battery pack is completely loaded on the transport trolley. When the battery replacement platform descends below the bottom of the transport trolley, the transport trolley drives the depleted battery pack to move horizontally to the charging bin for the transfer of the battery pack. The battery replacement platform is arranged to disassemble and assemble the battery pack of the electric vehicle. The separate transport trolley is arranged to receive the battery pack disassembled by the battery replacement platform, transfer the battery pack, and carry the full battery pack to the battery replacement platform. Then, the battery replacement platform assembles the full battery pack to the electric vehicle. During the transfer of the battery pack, the battery replacement platform does not move with the transport trolley. In addition, a single battery replacement platform can be arranged at the battery replacement position, and two transport trolleys are arranged to cooperate with each other. One transport trolley transports the depleted battery pack, and the other transport trolley transports the full battery pack to the battery replacement platform for assembly, so that the battery replacement device can realize efficient and rapid battery replacement without arranging multiple battery replacement platforms to cooperate with the transport trolleys, thereby reducing the cost of battery replacement.

[0010] Meanwhile, the transport trolley is provided with a first avoiding opening to cooperate with the battery replacement platform. After the battery replacement platform takes the battery to be replaced from the vehicle, the battery replacement platform carrying the battery pack descends below the first avoiding opening, and the taken battery pack is carried by the transport trolley and stays above the first avoiding opening, and is disconnected from the battery replacement platform and connected to the transport trolley. When the battery to be replaced needs to be assembled, the transport trolley carries the full battery pack above the battery replacement platform to the corresponding position, the battery replacement platform moves upward to the first avoiding opening to contact the full battery pack, and the full battery pack on the top of the transport trolley is lifted to disconnect the full battery pack from the transport trolley and load the full battery pack on the battery replacement platform. The battery replacement platform is raised to the battery replacement height adapted to the vehicle to assemble the battery pack. The first avoiding opening allows the battery replacement platform to pass through, but the battery pack cannot pass through, so that the battery pack is connected between the transport platform and the transport trolley during the lifting of the battery replacement platform.

[0011] In a preferred implementation manner of the battery replacement device, the transport trolley includes a vehicle body frame for carrying the battery to be replaced. The vehicle body frame includes a bottom plate provided with a first avoiding opening and a support portion vertically upwardly arranged on the bottom plate. The battery replacement platform moves vertically along the first avoiding opening to carry the battery pack from the support portion or place the battery pack on the support portion.

[0012] The support part provided on the bottom plate enables the battery pack to be carried by the support part during the lowering of the battery replacement platform, so that the transport trolley supports and carries the battery pack, or during the rising of the battery replacement platform, the battery replacement platform contacts the battery to be replaced when reaching the height of the support part, and drives the battery to be replaced to continue moving upward to the vehicle, so that the battery to be replaced is separated from the support part. By setting the structure of the bottom plate and the support part, the support strength of the transport trolley on the battery to be replaced located on the top of the transport trolley is strengthened, the carrying stability of the transport trolley during the transfer of the battery pack is ensured, the battery pack is prevented from falling, and the reliability of the battery replacement device is improved.

[0013] In a preferred implementation manner of the battery replacement device, the battery replacement platform comprises a first carrying part and a second carrying part for carrying the battery to be replaced, and the transport trolley comprises at least two first avoiding openings, the two first avoiding openings correspond to the first carrying part and the second carrying part respectively, and a partition beam is arranged between the two first avoiding openings.

The transport trolley is correspondingly provided with two first avoiding openings, which facilitates the alignment of the transport trolley with the first carrying part and the second carrying part through the two first avoiding openings, facilitates the smooth completion of the transfer of the battery pack between the transport trolley and the battery replacement platform in the height direction, and thus realizes the stable receiving of the battery to be replaced by the two. The partition beam arranged between the two first avoiding openings can make up for the strength loss caused by the arrangement of the two first avoiding openings on the transport trolley, so as to further ensure the movement stability of the transport trolley and the carrying capacity of the battery to be replaced.

[0057] The present application provides a battery replacement device, such as Figures 1 to 5 As shown, for disassembling and transporting the battery pack to be replaced during the battery replacement process, the battery replacement device comprises:

[0058] The battery replacement platform 100 is used to remove and install the battery pack to be replaced;

[0059] The transport trolley 200 is used to carry the battery pack to be replaced for transfer, and the transport trolley 200 is provided with a first avoiding opening 212 for the battery replacement platform 100 to pass through. The battery replacement platform 100 moves up and down relative to the battery replacement trolley through the first avoiding opening 212 to realize the interactive connection of the battery pack to be replaced between the battery replacement platform 100 and the transport trolley 200.

[0060] The battery replacement device of the scheme replaces the battery of the electric vehicle. After the vehicle to be replaced is parked and positioned above the battery replacement platform 100, the battery replacement platform 100 is raised to disassemble the battery pack of the electric vehicle. When the battery replacement platform 100 completes the disassembly of the depleted battery pack, the battery replacement platform 100 drives the depleted battery pack to descend to the contact of the transport trolley 200. When the depleted battery pack is completely loaded on the transport trolley 200, the battery replacement platform 100 continues to descend to below the bottom of the transport trolley 200. The transport trolley 200 drives the depleted battery pack to move horizontally to the charging bin for the transfer of the battery pack. By setting a separate transport trolley 200, the battery pack disassembled by the battery replacement platform 100 is transferred by the transport trolley 200. The full battery pack is loaded on the transport trolley 200, and the full battery pack is exchanged to the battery replacement platform 100. Then, the full battery pack is installed on the electric vehicle by the battery replacement platform 100. During the transfer of the battery pack, the battery replacement platform 100 does not move with the transport trolley 200. In other embodiments, a single battery replacement platform 100 is provided at the battery replacement position, and two transport trolleys 200 are provided. One transport trolley 200 transports the depleted battery pack, and the other transport trolley 200 transports the full battery pack to the battery replacement platform 100 for installation, thereby achieving efficient and rapid battery replacement. The battery replacement device does not need to set multiple battery replacement platforms 100 to work with the transport trolley 200, thereby reducing the cost of battery replacement.

[0061] At the same time, the transport trolley 200 is provided with a first avoiding port 212 cooperating with the battery replacement platform 100. After the battery replacement platform 100 takes the battery to be replaced from the vehicle, the battery replacement platform 100 loaded with the battery is lowered below the first avoiding port 212, and the removed battery is loaded by the transport trolley 200 and remains above the first avoiding port 212, and is separated from the battery replacement platform 100. When the battery to be replaced needs to be installed, the transport trolley 200 loads the full battery pack above the battery replacement platform 100 at the corresponding position. The battery replacement platform 100 moves up to above the first avoiding port 212 to contact the full battery pack. During the continuous upward movement of the battery replacement platform 100, the full battery pack on the top of the transport trolley 200 is lifted to make the full battery pack separate from the transport trolley 200 and be loaded on the battery replacement platform 100. The battery replacement platform 100 is raised to the battery replacement height adapted to the vehicle to install the battery pack. The battery replacement platform 100 passes through the first avoiding port 212, and the battery pack cannot pass through, thereby realizing the connection between the battery pack and the transport platform and the transport trolley 200 during the lifting of the battery replacement platform 100.

[0062] In one embodiment, as Figure 2 , Figure 4As shown, the transport trolley 200 includes a vehicle frame 210 for carrying the battery pack to be replaced, the vehicle frame 210 includes a bottom plate 211 provided with a first avoiding opening 212 and a support portion vertically upwardly arranged on the bottom plate 211, the battery swap platform 100 moves along the first avoiding opening 212 in the vertical direction to carry the battery pack from the support portion or place the battery pack on the support portion.

[0063] The present scheme sets the support portion on the bottom plate, so that during the lowering of the battery swap platform 100, the battery pack is carried on the support portion, realizing the support and carrying of the battery pack by the transport trolley 200, or during the rising of the battery swap platform 100, when reaching the height of the support portion, the battery swap platform 100 contacts the battery pack to be replaced and drives the battery pack to be replaced to continue moving upward to the vehicle, so that the battery pack to be replaced is separated from the support portion. By setting the structure of the bottom plate 211 and the support portion, the support strength of the transport trolley 200 to the battery pack to be replaced on the top of the transport trolley 200 is strengthened, the carrying stability of the transport trolley 200 during the transfer of the battery pack is ensured, the battery pack is prevented from falling, and the reliability of the battery swap device is improved.

[0064] Further, the battery swap platform 100 includes a first carrying portion 110 and a second carrying portion 120 for carrying the battery pack, the battery swap platform 100 includes two first avoiding openings 212, the two first avoiding openings 212 correspond to the first carrying portion 110 and the second carrying portion 120 respectively, and a partition beam 213 is arranged between the two first avoiding openings 212, the first carrying portion 110 and the second carrying portion 120 are respectively realized to move up and down in the vertical direction through the corresponding first avoiding openings 212. When the battery pack is located on the transport trolley 200, the partition beam 213 is used to carry the battery pack.

[0065] By setting the first carrying portion 110 and the second carrying portion 120 on the battery swap platform 100, the split type carrying of the battery pack to be replaced by the battery swap platform 100 is realized, which is beneficial to reduce the overall weight, reduce the consumption materials, reduce the cost, and facilitate the use and promotion, compared with the integrated setting of the carrying portion. The transport trolley 200 is correspondingly provided with two first avoiding openings 212, which is convenient for realizing the alignment of the transport trolley 200 with the first carrying portion 110 and the second carrying portion 120 through the two first avoiding openings 212, facilitating the smooth completion of the transfer of the battery pack between the transport trolley 200 and the battery swap platform 100 in the height direction, so as to realize the stable carrying of the battery pack to be replaced by the two. The partition beam 213 arranged between the two first avoiding openings 212 can make up for the strength loss caused by the setting of the two first avoiding openings 212 on the transport trolley 200, so as to further ensure the moving stability of the transport trolley 200 and the carrying strength of the battery pack to be replaced.

[0066] Further, as shown in FIG. 1, Figure 2 , Figure 5As shown, the support part includes first support plates 214 arranged on both sides along the moving direction of the transport trolley 200, which are arranged on the bottom plate 211.

[0067] The first support plates 214 are arranged on both sides along the length direction of the transport trolley 200, and long-distance support contact with the battery pack to be replaced is achieved from both sides, which is beneficial to the stable placement of the battery pack to be replaced on the transport trolley 200.

[0068] In addition, since the partition beam 213 is located between the two first avoiding openings 212, the top of the partition beam 213 can achieve support of the battery pack at the outer edge of the first support plates 214 at both ends, which realizes the stable placement of the battery pack to be replaced on the transport trolley 200, avoids uneven stress and offset and falling, and is beneficial to the operation stability and reliability of the transport trolley 200.
