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.

[0069] Battery exchange cabinet reference Figures 1 to 3 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.

[0070] 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.

[0071] 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.

[0072] 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.

[0073] 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.

[0074] 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.

[0075] The cabinet body 100 is provided with an entrance and exit 130 for batteries to enter and exit, and the entrance and exit 130 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 130, and sends the fully charged batteries out of the second battery compartment 110 in the cabinet through the entrance and exit 130, thereby completing the automatic battery replacement of the electric vehicle.

[0076] 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.

[0077] In some embodiments, reference Figure 3 The battery exchange transport device 200 includes a frame 220, and a first battery compartment 210 for accommodating a battery is formed in the frame 220.

[0078] At least one end of the frame 220 is provided with a battery inlet and outlet (not shown), and the battery inlet and outlet is connected to the first battery compartment 210. The battery enters the first battery compartment 210 through the battery inlet and outlet. The battery in the first battery compartment 210 is output through the battery inlet and outlet.

[0079] The battery replacement transport device 200 includes a telescopic device 300 , and the telescopic device 300 is disposed in the first battery compartment 210 . Figure 4 FIG. 1 is a structural diagram of the telescopic device 300 when the telescopic device 300 is in a retracted state and viewed from the top side thereof. Figure 5 FIG. 1 is a structural diagram of the telescopic device 300 when the telescopic device 300 is in a retracted state and viewed from the bottom side. Figure 6 FIG. 1 is a structural diagram of the telescopic device 300 when the telescopic device 300 is in an extended state and viewed from the top side. Figure 7 for Figure 6 A structural diagram of the structure viewed from another opposite side, Figure 8 It is a structural diagram observed from the bottom side of the telescopic device 300 when the telescopic device 300 is in the extended state.

[0080] The retractable device 300 includes a fixing portion 310 , and the fixing portion 310 is disposed in the first battery compartment 210 . Fig. 9is a structural diagram of the fixing portion 310 viewed from the top side, Fig.10 It is a structural diagram of the fixing portion 310 observed from the bottom side.

[0081] The telescopic device 300 further includes a moving assembly 320, and the moving assembly 320 is slidably connected to the fixing portion 310. The moving assembly 320 moves in a horizontal direction.

[0082] The telescopic device 300 further includes a driving component, which is configured to drive the moving component 320 to move so that the moving component 320 extends out of or retracts into the first battery compartment 210 through the battery access port.

[0083] The telescopic device 300 further includes a limiting portion 340, which is disposed on the moving assembly 320. The limiting portion 340 is configured to cooperate with the battery to drive the battery to move with the moving assembly 320.

[0084] The battery transfer process is described below by taking the transfer of batteries between the second battery compartment 110 of the battery exchange transfer device 200 and the first battery compartment 210 in the battery exchange cabinet as an example.

[0085] When the battery is loaded into the second battery compartment 110 in the battery swap cabinet using the battery swapping transport device 200, the battery is in the first battery compartment 210, and the limit part 340 cooperates with the battery. According to the position of the target second battery compartment 110, the battery swapping transport device 200 performs translational movement or lifting movement in the alley 120, so that the first battery compartment 210 of the battery swapping transport device 200 is facing the target second battery compartment 110, and the driving component is started, and the driving component drives the moving component 320 to extend out of the first battery compartment 210, and the moving component 320 extends into the target second battery compartment 110, thereby bringing the battery in the first battery compartment 210 into the target second battery compartment 110. The battery is loaded, and the limit part 340 releases the cooperation with the battery, and then the driving component drives the moving component 320 to retract into the first battery compartment 210, waiting for the next execution command.

[0086] When the battery in the second battery compartment 110 of the battery swap cabinet is taken out by using the battery swapping transfer device 200, according to the position of the target second battery compartment 110, the battery swapping transfer device 200 performs translational movement or lifting movement in the alley 120, so that the first battery compartment 210 of the battery swapping transfer device 200 is opposite to the target second battery compartment 110, and the driving component is started, and the driving component drives the moving component 320 to extend out of the first battery compartment 210, and the moving component 320 extends into the target second battery compartment 110, and the limiting portion 340 cooperates with the battery in the target second battery compartment 110, and then the driving component drives the moving component 320 to retract into the first battery compartment 210, thereby bringing the battery in the target second battery compartment 110 into the first battery compartment 210 and taking out the battery.

[0087] In the battery swap cabinet of this embodiment, only the battery swap transport device 200 needs to be equipped with a drive component, and no drive component is required in the second battery compartment 110 of the battery swap cabinet, thereby reducing the probability of failure in the second battery compartment 110. Since the drive component is provided on the battery swap transport device 200, when a failure occurs in the drive component, 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.

[0088] In the battery swap cabinet of this embodiment, only the battery swap transport device 200 needs to be equipped with a drive component, and no drive component is required in the second battery compartment 110 of the battery swap cabinet. The number of drive components is small and the energy consumption is low.

[0089] In some embodiments, battery entrances and exits are respectively disposed at opposite ends of the frame 220 , and the driving assembly is configured to drive the moving assembly 320 to extend or retract into the first battery compartment 210 through any of the battery entrances and exits.

[0090] Reference Figure 3 , the second battery compartments 110 are respectively arranged on opposite sides of the lane 120. The battery entrances and exits are respectively arranged on opposite ends of the first battery compartment 210. According to the position of the target second battery compartment 110, the mobile component 320 extends or retracts through the battery entrance and exit close to the target second battery compartment 110 to complete the battery transfer. In this way, the battery exchange transfer device 200 can complete the battery transfer of the second battery compartments 110 on both sides without setting a rotating mechanism.

[0091] In some embodiments, the telescopic device 300 further includes a lifting part (not shown), which is disposed between the fixing part 310 and the frame 220. For example, the lifting part is disposed between the fixing part 310 and the inner wall of the first battery compartment 210. The lifting part is configured to drive the fixing part 310 to rise and fall in the vertical direction so that the limiting part 340 is engaged with or separated from the battery. For example, the lifting part is a lifting motor.

[0092] When the battery is loaded into the second battery compartment 110 in the battery swap cabinet using the battery swapping transport device 200, the battery is in the first battery compartment 210, and the limiting part 340 cooperates with the battery. According to the position of the target second battery compartment 110, the battery swapping transport device 200 performs translational movement or lifting movement in the alley 120, so that the first battery compartment 210 of the battery swapping transport device 200 is facing the target second battery compartment 110, and the driving component is started, and the driving component drives the moving component 320 to extend out of the first battery compartment 210, and the moving component 320 extends into the target second battery compartment 110, thereby bringing the battery in the first battery compartment 210 into the target second battery compartment 110, and the battery is loaded, and then the lifting part is started, driving the fixed part 310 to move toward the side away from the battery, so that the limiting part 340 is away from the battery, and the limiting part 340 releases the cooperation with the battery, and then the driving component drives the moving component 320 to retract into the first battery compartment 210, waiting for the next execution command.

[0093] When the battery in the second battery compartment 110 of the battery swap cabinet is taken out by using the battery swapping transfer device 200, according to the position of the target second battery compartment 110, the battery swapping transfer device 200 performs translational movement or lifting movement in the alley 120, so that the first battery compartment 210 of the battery swapping transfer device 200 is opposite to the target second battery compartment 110, the driving component is started, and the driving component drives the moving component 320 to extend out of the first battery compartment 210, and the moving component 320 extends into the target second battery compartment 110, and then the lifting part is started to drive the fixed part 310 to move toward the side close to the battery, so that the limiting part 340 is close to the battery, the limiting part 340 cooperates with the battery, and then the driving component drives the moving component 320 to retract into the first battery compartment 210, thereby bringing the battery in the target second battery compartment 110 into the first battery compartment 210 and taking out the battery.

[0094] The telescopic device 300 is lifted and lowered in the vertical direction by the lifting part. The telescopic device 300 moves toward the direction close to the battery, so that the limiter 340 cooperates with the battery; the telescopic device 300 moves toward the direction away from the battery, so that the limiter 340 is separated from the battery. In this way, when the moving component 320 is telescopic, the limiter 340 is prevented from interfering with the battery, so that the moving component 320 cooperates with the battery after being telescoped into place.

[0095] In some embodiments, reference Figure 3 The telescopic device 300 is disposed on the top of the first battery compartment 210 .

[0096] The lifting part drives the fixing part 310 to move downward, so that the limiting part 340 moves toward the direction close to the battery, so that the limiting part 340 is matched with the battery.

[0097] The lifting part drives the fixing part 310 to move upward, so that the limiting part 340 moves in a direction away from the battery, so that the limiting part 340 is separated from the battery.

[0098] In some embodiments, reference Figure 3 and Figure 5 The limiting portion 340 includes two limiting plates, and the two limiting plates are arranged at intervals along the telescopic direction of the moving component 320.

[0099] The two limiting plates are configured to cooperate with the corresponding end sides of the battery. That is, one of the limiting plates abuts against the first end of the battery, and the other limiting portion 340 abuts against the second end of the battery, and the first end is opposite to the second end.

[0100] The two limiting plates are used to clamp and limit the battery, and the battery is pushed and pulled, thereby driving the battery to move horizontally along with the extension and retraction of the moving component 320 .

[0101] In some embodiments, the moving component 320 includes multiple moving parts, which are stacked in sequence, and two adjacent moving parts are slidably connected to each other. A moving part close to the fixed part 310 is slidably connected to the fixed part 310, and a limiting part 340 is set on a moving part away from the fixed part 310.

[0102] The driving assembly is configured to drive the plurality of moving parts to extend and retract step by step.

[0103] Multiple moving parts are stacked in sequence, and the driving components are used to achieve step-by-step extension and retraction. Figure 4 and Figure 5 As shown, the multiple moving parts and the fixed part 310 are stacked up and down, with a small volume and a compact structure. When the multiple moving parts are in the extended state, as shown in FIG. Figures 6 to 8 As shown, multiple moving parts are extended step by step to increase the extension length, so as to increase the conveying distance of the battery.
