Description

Technical Field

[0001] The utility model relates to the technical field of electric vehicles, and in particular to a battery exchange transport device and a battery exchange cabinet. Background Art

[0002] There are two main ways to charge the batteries of electric vehicles, one is charging piles, and the other is charging and swapping battery stations, referred to as battery swapping stations. Among them, charging the battery through a charging and swapping battery station is to drive the electric vehicle into the charging and swapping battery station, remove the low-power battery from the car, and then replace the fully charged battery with the car. The replaced low-power battery is transported to the charging device for charging. The car does not need to wait on site for the low-power battery to be charged, and the charging efficiency is high. This car charging mode is called battery swapping, which has become a gradually popular car charging mode.

[0003] A battery swap station is usually equipped with a battery swap cabinet, in which a battery swap device is installed to transfer low-power batteries or fully-charged batteries between the battery compartment in the battery swap cabinet and the battery compartment in the electric vehicle. A first battery compartment is installed in the battery swap device, and multiple second battery compartments are installed in the cabinet. When an electric vehicle needs to have its battery swapped, the electric vehicle enters the battery swap station, and the battery swap cabinet recognizes the electric vehicle entering. After interacting with the electric vehicle, the battery swap process begins. The battery is sent from the bottom of the vehicle into the first battery compartment of the battery swap device, and the battery swap device transports the old battery to the second battery compartment of the battery swap cabinet for charging, and takes out the fully-charged battery and transfers it to the vehicle, completing the battery swap process.

[0004] Rollers are provided at the bottom of the first battery compartment in the battery exchange device and the second battery compartment in the battery exchange cabinet. The rollers in the battery exchange device are driven by a motor to send the battery into the second battery compartment in the battery exchange cabinet, while the rollers in the second battery compartment use a motor or other mechanical external force to collect the battery into the second battery compartment. The battery output process is the opposite of the above process.

[0005] The rollers in the battery compartment of the battery swap cabinet and the battery swap device are driven by motors, which consumes corresponding electricity and has high energy consumption. If a gear structure is used to drive the rollers through mechanical external force, it needs to be precisely connected to the transmission structure of the battery swap device. If the transmission structure in the battery compartment of the battery swap cabinet fails, because its components are located inside the battery swap cabinet, personnel need to enter the battery swap cabinet to repair the failure during replacement and maintenance, which is inconvenient to operate.

[0006] The above information disclosed in the background technology is only used to increase the understanding of the background technology of the present application, and therefore, it may include information that does not constitute the prior art known to ordinary technicians in the field. Summary of the invention

[0046] The present embodiment discloses a battery swap cabinet, which is used to swap batteries for electric vehicles. Low-charged batteries in the battery compartment of the electric vehicle are placed in the battery compartment of the battery swap cabinet for charging, and fully-charged batteries in the battery compartment of the battery swap cabinet are replaced in the battery compartment of the electric vehicle.

[0047] Battery exchange cabinet reference Figure 1 and Figure 2 The cabinet 100 includes a plurality of battery compartments, which are designated as second battery compartments 110. The second battery compartments 110 are used to store low-power batteries or fully-charged batteries. Low-power batteries enter the second battery compartments 110, which are provided with charging contacts for docking with the charging interface of the battery, so as to automatically charge the low-power batteries in the second battery compartments 110.

[0048] The second battery compartment 110 in the cabinet 100 is arranged in multiple layers, thereby increasing the number of compartments and the storage capacity of batteries in the cabinet. Figure 2 Shown is a top view of the cabinet layout.

[0049] A battery exchange transfer device 200 is provided in the cabinet body 100, and the battery exchange transfer device 200 is used to transfer batteries between the battery compartment of the electric vehicle and the second battery compartment 110 of the battery exchange cabinet. Specifically, the depleted batteries in the battery compartment of the electric vehicle are transferred to the second battery compartment 110 of the battery exchange cabinet for charging, and the fully charged batteries in the second battery compartment 110 of the battery exchange cabinet are transferred to the battery compartment of the electric vehicle.

[0050] An alley 120 is provided in the cabinet 100, and a second battery compartment 110 is arranged next to the alley 120. The battery replacement transport device 200 is provided in the alley 120. The battery replacement transport device 200 moves along the alley 120 to transport the battery to the corresponding second battery compartment 110 or take the battery out of the corresponding second battery compartment 110.

[0051] The battery replacement transport device 200 can perform lifting and lowering movements, horizontal movement, and vertical movement in the alley 120 to transport the battery to the corresponding second battery compartment 110 at different heights, or to take the battery out of the corresponding second battery compartment 110 at different heights.

[0052] The device for driving the battery exchange transport device 200 to lift, move horizontally, and move vertically can refer to the prior art, and this embodiment will not be described in detail. For example, a common chain drive, screw drive, etc. can be used.

[0053] The cabinet body 100 is provided with an entrance and exit 140 for batteries to enter and exit, and the entrance and exit 140 is connected to the lane 120. The battery replacement transport device 200 receives the depleted batteries replaced from the battery compartment of the electric vehicle through the entrance and exit 140, and sends the fully charged batteries out of the second battery compartment 110 in the cabinet through the entrance and exit 140, thereby completing the automatic battery replacement of the electric vehicle.

[0054] The battery exchange transfer device 200 is built into the battery exchange cabinet, and an independent installation space is provided for it through the alley 120. The second battery compartment 110 is arranged on both sides of the alley 120. The structure layout inside the cabinet is compact, the space utilization rate inside the cabinet is high, and the battery storage capacity is increased.

[0055] In some embodiments, reference Figure 3 The battery exchange transport device 200 includes a frame 280, and a first battery compartment 210 for accommodating a battery 300 is formed in the frame 280.

[0056] At least one end of the frame 280 is provided with a battery inlet and outlet (not shown), which is connected to the first battery compartment 210. The battery 300 enters the first battery compartment 210 through the battery inlet and outlet. The battery 300 in the first battery compartment 210 is discharged through the battery inlet and outlet.

[0057] The battery exchange transport device 200 includes a driving wheel 220, which is disposed at the bottom of the first battery compartment 210. The driving wheel 220 is configured to carry and transport the battery 300 transported through the battery entrance and exit. The driving wheel 220 is configured with a driving device (not shown), and when the battery 300 is located in the first battery compartment 210, the battery 300 is placed on the driving wheel 220.

[0058] The battery exchange transport device 200 includes a pressure wheel 240, which is disposed on the top of the first battery compartment 210. The pressure wheel 240 is configured to contact the top side of the battery.

[0059] When transferring the battery 300 in the first battery compartment 210 to the second battery compartment 110 in the battery exchange cabinet, the battery exchange transfer device 200 moves in the alley 120 according to the position of the target second battery compartment 110, so that the first battery compartment 210 is opposite to the second battery compartment 110, and the battery entrance and exit of the first battery compartment 210 is opposite to the battery entrance and exit of the second battery compartment 110, the bottom side of the battery 300 is in contact with the driving wheel 220, and the top side of the battery 300 is in contact with the pressure wheel 240. The driving wheel 220 rotates under the drive of the driving device, and the friction between the battery 300 and the driving wheel 220 and the pressure wheel 240 is used to transport the battery 300, so that the battery 300 in the first battery compartment 210 moves toward the direction close to the second battery compartment 110 until the battery 300 moves into the second battery compartment 110.

[0060] When transferring the battery 300 in the second battery compartment 110 to the first battery compartment 210 of the battery exchange transport device 200, the battery exchange transport device 200 moves in the alley 120 according to the position of the target second battery compartment 110, so that the first battery compartment 210 is opposite to the second battery compartment 110, and the battery entrance and exit of the first battery compartment 210 is opposite to the battery entrance and exit of the second battery compartment 110. One end of the battery 300 in the second battery compartment 110 enters the first battery compartment 210 through the battery entrance and exit. At this time, a part of the battery 300 enters the first battery compartment 210, the bottom side of the battery 300 contacts the driving wheel 220, and the top side of the battery 300 contacts the pressure wheel 240. The driving wheel 220 rotates under the drive of the driving device, and the friction between the battery 300 and the driving wheel 220 and the pressure wheel 240 is used to realize the transportation of the battery 300, so that the battery 300 moves toward the inside of the first battery compartment 210 until the battery 300 moves into the first battery compartment 210.

[0061] In the battery exchange transport device 200, only the driving wheel 220 needs to be equipped with a driving device, and the pressure wheel 240 on the top does not need to be equipped with a driving device. The battery 300 uses the drive of the driving wheel 220 and the friction between the driving wheel 220 and the pressure wheel 240 to achieve transport and transportation, thereby reducing the manufacturing cost of the battery exchange transport device 200.

[0062] In one embodiment, the driving wheel 220 is a Furley driving wheel.

[0063] In some embodiments, reference Figure 3 A rolling portion 130 , such as a Furley wheel, is disposed at the bottom of the second battery compartment 110 .

[0064] Taking the transportation of the battery 300 into the second battery compartment 110 as an example, the battery replacement transport device 200 moves to a position facing the target second battery compartment 110, the battery entrance and exit of the first battery compartment 210 faces the battery entrance and exit of the second battery compartment 110, and the driving wheel 220 and the rolling part 130 are in the same plane. As the driving wheel 220 rotates, the battery 300 in the first battery compartment 210 is transported into the second battery compartment 110, and the bottom of the battery 300 contacts the rolling part 130. The rolling part 130 acts as a driven wheel, and the battery 300 is continuously transported to the interior of the second battery compartment 110.

[0065] There is no need to configure a driving device in the second battery compartment 110 of the battery swap cabinet, and the rolling part 130 is a driven wheel, which reduces the probability of failure in the second battery compartment 110. Since the driving device is arranged on the battery swap transport device 200, when the driving device fails, the battery swap transport device 200 can be moved to the outside of the battery swap cabinet for maintenance, thereby improving the convenience of maintenance.

[0066] In some embodiments, a lifting plate is provided in the first battery compartment 210, which is referred to as a first lifting plate 250, and a driving wheel 220 is provided on the first lifting plate 250. The first lifting plate 250 serves as a mounting carrier for multiple driving wheels 220, so that the multiple driving wheels 220 are on the same plane.

[0067] An installation space is formed between the first lifting plate 250 and the bottom of the frame 280 , and a first lifting driving unit 260 is disposed in the installation space. The first lifting driving unit 260 is used to drive the first lifting plate 250 to move upward or downward.

[0068] In a specific embodiment, the first lifting drive unit 260 is a lifting motor. A plurality of lifting motors are provided, and the plurality of lifting motors are symmetrically arranged relative to the center of the first lifting plate 250 to improve the movement stability and reliability of the first lifting plate 250.

[0069] When the battery 300 is transported from the outside to the first battery compartment 210, the first lifting plate 250 is first in a low position. At this time, the distance between the first lifting plate 250 and the pressure wheel 240 increases, which facilitates the battery 300 to enter the first battery compartment 210. After one end of the battery 300 enters the first battery compartment 210, the first lifting plate 250 rises, and the distance between the first lifting plate 250 and the pressure wheel 240 decreases, so that the lower side of the battery 300 contacts the driving wheel 220, and the upper side of the battery 300 contacts the pressure wheel 240. The battery 300 relies on the rotation of the driving wheel 220 and the friction between the driving wheel 220 and the pressure wheel 240 to achieve transportation into the first battery compartment 210.

[0070] In some embodiments, a second lifting plate (not shown) is disposed in the first battery compartment 210, and a pressing wheel 240 is disposed on the second lifting plate. The second lifting plate serves as a mounting carrier for the plurality of pressing wheels 240, so that the plurality of pressing wheels 240 are on the same plane.

[0071] An installation space is formed between the second lifting plate and the bottom of the frame 280 , and a second lifting driving unit (not shown) is disposed in the installation space. The second lifting driving unit is used to drive the second lifting plate to move upward or downward.

[0072] In a specific embodiment, the second lifting drive unit is a lifting motor. A plurality of lifting motors are provided, and the plurality of lifting motors are symmetrically arranged relative to the center of the second lifting plate, thereby improving the movement stability and reliability of the second lifting plate.

[0073] When the battery 300 is transported from the outside to the first battery compartment 210, the second lifting plate is first in a high position. At this time, the distance between the second lifting plate and the driving wheel 220 increases, which facilitates the battery 300 to enter the first battery compartment 210. After one end of the battery 300 enters the first battery compartment 210, the second lifting plate descends, and the distance between the second lifting plate and the driving wheel 220 decreases, so that the lower side of the battery 300 contacts the driving wheel 220, and the upper side of the battery 300 contacts the pressure wheel 240. The battery 300 relies on the rotation of the driving wheel 220 and the friction between the driving wheel 220 and the pressure wheel 240 to achieve transportation into the first battery compartment 210.

[0074] In some embodiments, the battery 300 placed in the second battery compartment 110 has a portion extending out of the second battery compartment 110 . In other words, when the battery 300 is placed in the second battery compartment 110 , a portion of the battery 300 extends out of the second battery compartment 110 .

[0075] When taking out the battery 300 in the second battery compartment 110, the battery exchange transport device 200 moves horizontally in the direction approaching the target second battery compartment 110. At this time, the distance between the driving wheel 220 and the pressure wheel 240 is greater than the thickness of the battery 300, so that the extended part of the battery 300 can be smoothly inserted into the first battery compartment 210 without resistance. Then the distance between the driving wheel 220 and the pressure wheel 240 is reduced, so that the lower side of the battery 300 contacts the driving wheel 220, and the upper side of the battery 300 contacts the pressure wheel 240. The battery 300 relies on the rotation of the driving wheel 220 and the friction between the driving wheel 220 and the pressure wheel 240 to achieve transportation into the first battery compartment 210.

[0076] When the battery 300 is placed in the second battery compartment 110, the battery exchange transport device 200 moves to a position facing the target second battery compartment 110, and the battery 300 is transported to the outside of the first battery compartment 210 by relying on the rotation of the driving wheel 220 and the friction between the driving wheel 220 and the pressure wheel 240. The battery 300 moves into the second battery compartment 110, and the bottom side of the battery 300 contacts the rolling portion 130 at the bottom of the second battery compartment 110. When the battery 300 moves into place in the second battery compartment 110, a portion of the battery 300 extends out of the second battery compartment 110, which means that a portion of the battery 300 is still located in the first battery compartment 210 at this time. Then the distance between the driving wheel 220 and the pressure wheel 240 increases, and the battery exchange transport device 200 moves horizontally away from the second battery compartment 110. The pressure wheel 240 and the driving wheel 220 release the pressure on the battery 300, and the battery exchange transport device 200 detaches from the battery 300.

[0077] Arranging a portion of the battery 300 to extend out of the second battery compartment 110 , on the one hand, helps to reduce the cost of the battery swap cabinet; on the other hand, it also facilitates the transfer of the battery 300 between the first battery compartment 210 and the second battery compartment 110 .

[0078] In some embodiments, when the battery 300 is placed in the second battery compartment 110, along the length direction of the battery 300, two-thirds of the battery 300 is located in the second battery compartment 110, and one-third of the battery 300 is located outside the second battery compartment 110. Such a configuration helps to ensure the placement reliability of the battery 300 in the second battery compartment 110 and prevent the battery 300 from falling out of the second battery compartment 110.

[0079] In some embodiments, the battery 300 placed in the first battery compartment 210 has a portion extending out of the first battery compartment 210 .

[0080] In other words, when the battery 300 is placed in the first battery compartment 210 , a portion of the battery 300 protrudes out of the first battery compartment 210 .

[0081] When transporting the battery 300 in the first battery compartment 210 to the second battery compartment 110, the battery exchange transport device 200 moves horizontally toward the target second battery compartment 110, so that the extended portion of the battery 300 can be just inserted into the second battery compartment 110, and the battery 300 is transported to the second battery compartment 110 by the rotation of the driving wheel 220 and the friction between the driving wheel 220 and the pressure wheel 240. After the battery 300 is transported to the second battery compartment 110, the distance between the driving wheel 220 and the pressure wheel 240 increases, and the battery exchange transport device 200 moves horizontally away from the second battery compartment 110, and the pressure wheel 240 and the driving wheel 220 release the pressure on the battery 300, and the battery exchange transport device 200 is separated from the battery 300.

[0082] Arranging a portion of the battery 300 to extend outward from the first battery compartment 210 , on the one hand, helps to reduce the manufacturing cost of the battery replacement transport device 200 ; on the other hand, it also facilitates the transport of the battery 300 between the first battery compartment 210 and the second battery compartment 110 .

[0083] In some embodiments, when the battery 300 is placed in the first battery compartment 210, along the length direction of the battery 300, two-thirds of the battery 300 is located in the first battery compartment 210, and one-third of the battery 300 is located outside the first battery compartment 210. Such a configuration helps to ensure the placement reliability of the battery 300 in the first battery compartment 210 and prevent the battery 300 from falling out of the first battery compartment 210.

[0084] In some embodiments, reference Figure 3 A battery entrance and exit is set at one end of the frame 280, and a driving wheel 220 and a roller 230 are set at the bottom of the first battery compartment 210. The driving wheel 220 is set close to the battery entrance and exit, and the roller 230 is set away from the battery entrance and exit.

[0085] The driving wheel 220 is arranged close to the battery entrance and exit, so that the battery 300 can enter and exit the first battery compartment 210 under the drive of the driving wheel 220 , thereby facilitating the transportation of the battery 300 .

[0086] In some embodiments, the pressure wheel 240 is located above the driving wheel 220, so that the battery 300 is pressed between the driving wheel 220 and the pressure wheel 240, thereby increasing the friction between the battery 300 and the two and improving the reliability of the battery 300 transportation.

[0087] In some embodiments, second battery compartments 110 are respectively disposed on opposite sides of the lane 120 .

[0088] The battery swapping transport device 200 includes a rotating part 270, which is used to drive the battery swapping transport device 200 to rotate so that the battery entrance and exit are directly opposite to the first battery compartment 210 of the battery swapping cabinet.

[0089] As for the specific structure of the rotating part 270 , a geared disc or other structure in the prior art may be adopted, and this embodiment does not make any specific limitation.
