DETAILED DESCRIPTION

[0036] The embodiments of the present application are described in detail below, and examples of the embodiments are shown in the accompanying drawings, wherein the same or similar reference numerals throughout represent the same or similar elements or elements having the same or similar functions. The embodiments described below with reference to the accompanying drawings are exemplary and are intended to be used to explain the present application, and should not be construed as limiting the present application.

[0037] During the battery replacement process of new energy vehicles, the power battery is removed from the vehicle body, the battery replacement station transfers the power battery to the battery storage rack, and the power battery needs to be placed in the correct position.

[0038] In some examples, the battery racks of battery swap stations can store dozens of power batteries, so there are dozens of battery rack storage locations. In order to ensure that the power batteries are correctly transported to the correct position of the battery racks so that the charging connectors can smoothly charge the replaced power batteries, in-place sensors are installed at the rear of each battery rack, totaling dozens of sensors and related wiring harnesses. This method of installing in-place sensors at the rear of each battery rack has a large number of sensors, and the debugging consistency of the sensors is poor, which easily leads to the failure to detect the presence of the battery during the battery swap process, affecting the failure rate and high cost.

[0039] Based on this, this application proposes a power battery transfer system, which eliminates the sensors on each layer and centrally arranges the sensors on the hoist fork, thereby reducing the number of sensors and reducing the problem of poor modulation consistency, thereby improving the success rate of battery replacement and ensuring the driver's operating efficiency and battery replacement experience. And centrally arranging the sensors on the hoist fork not only reduces the number of sensors, but also reduces the number of related wiring harnesses and IOLINK (input and output interfaces), saving costs.

[0040] Figure 1 It is a schematic diagram of a power battery transport system according to an embodiment of the present application.

[0041] As an example, Figure 1 As shown, the power battery transport system 100 includes: a bracket module 101; a fork module 102, the fork module 102 is connected to the bracket module 101, and the fork module 102 is configured to move in a preset direction when transporting the power battery to transport the power battery; a sensor module 103, the sensor module 103 is connected to the bracket module 101 and the fork module 102, and the sensor module 103 is configured to determine the moving distance of the fork module when the fork module 102 moves in a preset direction; a charging interface control module 104, the charging interface control module 104 communicates with the sensor module 103, and the charging interface control module 104 is configured to control the charging interface to charge the power battery when the moving distance is a preset distance.

[0042] Exemplarily, the bracket module 101 is used to carry power batteries and serve as a fixed bracket for transporting power batteries. It can be understood that the bracket module 101 is a fixed mechanical mechanism in the battery swap rack. Of course, the bracket module 101 can move in the vertical direction to place the power batteries on different layers. The fork module 102 is mechanically connected to the bracket module 101. When transporting the power battery, the fork module 102 moves in a preset direction to transport the power battery. For example, the battery storage bin includes a left storage bin and a right storage bin. When the power battery needs to be transported to the left storage bin, the fork module 102 moves horizontally to the left to transport the power battery. It should be noted that when the fork module 102 transports the power battery, the power battery has been limited and fixed. For example, the power battery can be limited by rotating the fork. During transportation, the power battery is relatively stationary relative to the fork module 102. The sensor module 103 includes a plurality of sensors, some of which are fixed on the bracket module 101, and some of which are fixed on the fork module 102. When the fork module 102 moves in a preset direction, the sensor module 103 detects the moving distance of the fork module 102. The charging interface control module 104 communicates with the sensor module 103. When the moving distance of the fork module 102 is a preset distance, the charging interface control module 104 controls the charging interface to charge the power battery. For example, the charging interface can be controlled to be pressed down to contact the power battery, and the power battery is charged through the charging interface.

[0043] The power battery transfer system of the present application eliminates the sensors on each layer and centrally arranges the sensors on the lifting machine fork. By monitoring the moving distance of the fork, it determines whether the power battery is transferred in place, which greatly reduces the number of sensors and reduces costs.

[0044] Figure 2 It is a schematic diagram of a power battery transmission process according to an embodiment of the present application.

[0045] like Figure 2 As shown, the power battery 201 is removed from the bottom of the battery swap vehicle and falls onto the power battery transfer slide 202. Figure 2 The power battery at position 1 is shown. The power battery transfer slide 202 transfers the power battery 201 at position 1 to position 2, and the battery at position 2 is parked on a vertically liftable hoist. When the power battery 201 at position 2 is stably parked on the vertically liftable hoist, the cylinder rotating fork 203 can hold the power battery 201 at position 2 tightly and limit it.

[0046] Figure 3 It is a schematic diagram of the process of putting a power battery into a battery compartment according to an embodiment of the present application.

[0047] like Figure 3As shown, the cylinder rotates the fork 203 to hold the power battery 201 at position 2 tightly and then transports the power battery 201 at position 2 to position 3. When the power battery 201 at position 3 is parked stably, the battery in-position sensor 302 will trigger that the battery is already in place. When the PLC (Programmable Logic Controller) receives the signal from the battery in-position sensor 302, it will send an action instruction to the power battery charging interface 301, and the power battery charging interface 301 will complete the connection with the power battery 201 at position 3 to realize the function of charging the low-power battery.

[0048] Among them, the function of the battery in-place sensor 302 is to detect whether the power battery in position 3 is placed in the correct parking position, and to ensure that when the power battery charging interface 301 is pressed down and combined with the power battery, there will be no damage to the equipment due to the docking position deviation. In order to ensure the battery swapping operation capacity in the battery swap station, dozens of batteries need to be stored in a stacked arrangement in the battery swap station. If a battery in-place sensor is installed behind each layer of power battery to implement the power battery charging connector action command, the number of sensors and adapter in-place sensors in the entire station will increase with the number of batteries, and the cost is relatively high.

[0049] During the entire transfer process of the power battery, the cylinder rotating fork 203 completely limits the power battery, and the distance the power battery moves is physically limited. As long as there is no deviation in the process of transferring the power battery from position 2 to position 3, the power battery charging interface 301 will match the power battery 201 at position 3 and there will be no position deviation. Therefore, the present application cancels the sensors on each layer and concentrates the sensors on the hoist fork to detect the stability of the process from position 2 to position 3 to achieve the original function.

[0050] As an example, the fork module includes a first fork sub-module and a second fork sub-module, the preset directions include a horizontal first direction and a horizontal second direction, the first fork sub-module is configured to move in the horizontal first direction when transporting the power battery to transport the power battery; the second fork sub-module is configured to move in the horizontal second direction when transporting the power battery to transport the power battery; wherein the horizontal first direction and the horizontal second direction are opposite.

[0051] Exemplarily, the fork module includes a first fork submodule and a second fork submodule, and the preset direction includes a horizontal first direction and a horizontal second direction. In order to increase the battery swapping operation capacity, dozens of power batteries are stored in a stacked arrangement in the battery swap station. The battery storage compartment may include storage compartments on both sides, for example, Figure 4The schematic diagram of the battery storage bin is shown. The fork module includes a first fork submodule 401 and a second fork submodule 402, and the preset direction includes a first horizontal direction and a second horizontal direction, and the first horizontal direction is opposite to the second horizontal direction. It can be understood that the first fork submodule 401 is used to transport the power battery in the first horizontal direction, and the second fork submodule 402 is used to transport the power battery in the second horizontal direction.

[0052] For example, Figure 4 From the perspective shown, the first horizontal direction may be horizontal to the left, and the second horizontal direction may be horizontal to the right. When transporting the power battery, the first fork module 401 moves horizontally to the left to transport the power battery placed in the storage bin on the left. When transporting the power battery, the second fork module 402 moves horizontally to the right to transport the power battery placed in the storage bin on the right. Of course, the first fork module 401 may also move to the right, and the second fork module 402 may also move to the left. The first fork module 401 and the second fork module 402 have opposite movement directions when transporting the battery.

[0053] For example, Figure 5 As shown, when the first fork module 401 is transporting the power battery, it moves horizontally to the left and places the power battery in the storage bin on the left. Figure 6 As shown, when transporting the power battery, the second fork module 402 moves horizontally to the right and places the power battery in the storage bin on the right.

[0054] As an example, Figure 7 As shown, the first fork submodule includes a first primary fork 10 and a first secondary fork 20, the first primary fork 10 is connected to the bracket module, the first secondary fork 20 is connected to the first primary fork 10, and the first secondary fork 20 and the first primary fork 10 both move in a first horizontal direction.

[0055] For example, Figure 7 The area shown in the middle box is as follows Figure 4 The position of the power battery shown before it is transported to the storage bin can be understood. Figure 7 It is a top view of the power battery when it is transported to the storage bin. The first horizontal direction can be horizontally to the left. The first fork submodule includes a first-level fork 10 and a first-level fork 20, wherein the first-level fork 10 and the first-level fork 20 can both be narrow forks. When transporting the power battery to the left, the first-level fork 10 extends to the left, and when the first-level fork 10 extends to the farthest part of its own travel, the first-level fork 20 continues to extend to the left. The present application designs a first-level fork and a second-level plug-in to cooperate in transporting power batteries, which can save costs. Of course, it is also possible to design only one first-level fork to transport the battery in place at one time.

[0056] As an example, Figure 7 As shown, the sensor module includes a first sensor 1 and a second sensor 2, the first sensor 1 is fixed on the first-level fork 10, and the second sensor 2 is fixed on the bracket module, the first sensor 1 is configured to determine the first moving distance of the first-level fork 20 when the first-level fork 20 moves in the horizontal first direction; the second sensor 2 is configured to determine the second moving distance of the first-level fork 10 when the first-level fork 10 moves in the horizontal first direction.

[0057] Exemplarily, the first sensor 1 is fixed at the front end of the first primary fork 10 to detect the first moving distance of the first secondary fork 20. The second sensor 2 is fixed to the overall frame through a bracket to detect the second moving distance of the first primary fork 10.

[0058] Figure 8 Schematic diagram of a sensor according to an embodiment of the present application.

[0059] like Figure 8 As shown, the first sensor 1 includes a sensor sensing sheet 801 and a sensor fixing structure 802. The first sensor 1 is fixed on the sensor fixing structure 802, and then fixed on the bracket through the sensor fixing structure 802, and is relatively stationary with the first primary shift fork 10. When the first and second shift forks move, the first moving distance of the first and second shift forks 20 is detected. The fixing method of other sensors is similar to that of the first sensor, and will not be repeated.

[0060] As an example, the preset distance includes a first preset distance and a second preset distance, the first sensor 1 and the second sensor 2 both communicate with the charging interface control module 104, and the charging interface control module 104 is configured to control the charging interface to charge the power battery when the first moving distance is the first preset distance and the second moving distance is the second preset distance.

[0061] For example, the first moving distance detected by the first sensor 1 and the second moving distance detected by the second sensor 2 can be measured in advance in an experiment. When the first moving distance is the first preset distance and the second moving distance is the second moving distance, it means that the transportation of the power battery has reached the correct position. At this time, the charging interface control module 104 can control the charging interface to charge the power battery. For example, the charging interface can be controlled to press down and contact the power battery to charge the power battery.

[0062] As an example, if the power battery is transported to the left, the first-level fork 10 moves to the left, and the second sensor 2 is fixed to the overall frame through a bracket to detect the stroke of the first-level fork 10 to see whether the stroke of the first-level fork 10 is in place. The first sensor 1 is fixed to the first-level fork. When the first-level fork 10 moves, the first sensor 1 also moves, so the first sensor 1 is used to detect the movement stroke of the first-level fork 20. When the battery is transported to the left, the first-level fork and the first-level fork both move to the left, and the movement stroke is set. The movement stroke in place indicates that the battery is placed in the correct position. The travel distance detected by the first sensor and the second sensor is set at the beginning of the experiment. For example, the first-level fork stroke is 845mm and the second-level fork stroke is 1690mm. When the first moving distance is the first preset distance, the second sensor 2 is triggered. When the second moving distance is the second preset distance, the first sensor 1 is triggered, and the first sensor 1 and the second sensor 2 both communicate with the charging interface control module 104. The charging interface control module 104 controls the charging interface to charge the power battery when receiving the trigger signal of the first sensor 1 and the second sensor 2.

[0063] In the present application, the first sensor and the second sensor are used as the switch signal determination for the left battery. When the sensor signal is triggered, the charging connector on the battery rack is pressed down to charge the low-power battery.

[0064] By monitoring whether the shift fork has moved the right distance, it can detect whether the power battery has reached the correct position. This method greatly reduces the number of sensors required and solves the problem of poor modulation consistency between sensors, thereby improving the success rate of battery replacement, ensuring the driver's operational efficiency and battery replacement experience, and reducing costs.

[0065] As an example, Figure 7 As shown, the second fork submodule includes a second-level fork 30, a second-level fork 40 and a third-level fork 50, the second-level fork 30 is connected to the bracket module, the second-level fork 40 is connected to the second-level fork 30, the third-level fork 50 is connected to the second-level fork 30, and the second-level fork 30, the second-level fork 40 and the third-level fork 50 all move in the second horizontal direction.

[0066] Exemplarily, the horizontal second direction may be horizontal to the right. The second fork submodule includes a second-level fork 30, a second-level fork 40 and a third-level fork 50, wherein the second-level fork 30, the second-level fork 40 and the third-level fork 50 may all be wide forks. One end of the second-level fork 40 and the third-level fork 50 is fixed on the second-level fork 30. When transporting the power battery to the right, the second-level fork 30 extends to the right, and when the second-level fork 30 extends to the farthest point of its own travel, the second-level fork 40 and the third-level fork 50 continue to extend to the right. The second-level fork 40 and the third-level fork 50 may be symmetrical structures. The present application designs a first-level fork and a second-level plug-in to cooperate with each other to transport the power battery, which can save costs. Of course, it is also possible to design only one first-level fork to transport the battery in place at one time.

[0067] As an example, Figure 7 As shown, the sensor module includes a third sensor 3, a fourth sensor 4 and a fifth sensor 5, the third sensor 3 is fixed on the bracket module, the fourth sensor 4 and the fifth sensor 5 are both fixed on the second-level fork 30, the fourth sensor 4 and the fifth sensor 5 are symmetrically arranged, the third sensor 3 is configured to determine the third moving distance of the second-level fork 30 when the second-level fork 30 moves in the horizontal second direction; the fourth sensor 4 is configured to determine the fourth moving distance of the second-level fork 40 when the second-level fork 40 moves in the horizontal second direction; the fifth sensor 5 is configured to determine the fifth moving distance of the third-level fork 50 when the third-level fork 50 moves in the horizontal second direction.

[0068] Exemplarily, the third sensor 3 is fixed to the overall frame through a bracket, and is used to detect the third moving distance of the second primary fork 30, the fourth sensor 4 is fixed to the second primary fork 30, the fifth sensor 5 and the fourth sensor 4 are symmetrically arranged, and the fifth sensor 5 is also fixed to the second primary fork 30. The fourth sensor 4 is used to detect the fourth moving distance of the second secondary fork 40. The fifth sensor 5 is used to detect the fifth moving distance of the third secondary fork 50.

[0069] As an example, the preset distance includes a third preset distance, a fourth preset distance, and a fifth preset distance. The third sensor 3, the fourth sensor 4, and the fifth sensor 5 all communicate with the charging interface control module 104. The charging interface control module 104 is configured to control the charging interface to charge the power battery when the third moving distance is the third preset distance, the fourth moving distance is the fourth preset distance, and the fifth moving distance is the fifth preset distance.

[0070] Exemplarily, the triggering conditions of the third sensor 3, the fourth sensor 4 and the fifth sensor 5 are similar to those of the first sensor 1 and the second sensor. When the third moving distance detected by the third sensor 3 is the third preset distance, the fourth moving distance detected by the fourth sensor 4 is the fourth preset distance, and the fifth moving distance detected by the fifth sensor 5 is the fifth preset distance, it indicates that the transportation of the power battery has reached the correct position. At this time, the charging interface control module 104 can control the charging interface to charge the power battery.

[0071] The present application utilizes the third sensor, the fourth sensor, and the fifth sensor as the switch signal determination for the right battery. When the sensor signal is triggered, the charging connector on the battery rack is pressed down to charge the low-power battery.

[0072] This application detects whether the power battery has reached the correct position by monitoring whether the fork has moved the right distance. This method greatly reduces the number of sensors to be set up, solves the problem of poor modulation consistency between sensors, thereby improving the success rate of battery replacement, ensuring the driver's operating efficiency and battery replacement experience, and reducing costs.

[0073] As an example, the process of transporting the power battery to the side is similar to the process of transporting the power battery to the left side, and the sensors are used to detect the fork travel. The fork movement travel detected by the third sensor 3 in the middle and the two sensors on the right side is used to determine whether the battery is placed in the correct position. The third sensor in the middle detects the first-stage fork travel, and the two sensors on the right are used to detect the travel of the upper and lower second-stage forks respectively. When the travel of these three sensors reaches the preset travel distance, it means that the battery has been transported to the right place.

[0074] As an example, the third sensor 3 is further configured to determine the position information of the fork module before transporting the power battery; wherein the power battery is transported when the position information of the fork module indicates that the fork module is located at the origin position.

[0075] For example, the original position of the fork module is as follows: Figure 4 As shown, the third sensor 3 can also detect the retraction of the fork module, and start the next transportation when the fork module completes the previous power battery transportation.

[0076] As an example, the position information of the fork module includes the first position information of the first-level fork and the second position information of the second-level fork. When the first position information represents that the first-level fork is located at the origin position and the second position information represents that the second-level fork is located at the origin position, the power battery is transported.

[0077] For example, the third sensor can detect both the second-stage shift fork on the right and the first-stage shift fork on the left. The first-stage shift fork returns after transporting the power battery, and the third sensor in the middle can also be triggered through the mechanical structure. After transporting the battery, the shift fork structures on both sides will retract. The third sensor detects whether the two first-stage shift forks can be retracted to the original position ( Figure 4 ), and determine whether the fork module is at the origin position before the start of transmission. When the first-level fork is at the origin position and the second position information indicates that the second-level fork is at the origin position, the power battery is transported.

[0078] This application adds 5 in-place sensors on the bracket module to replace dozens of in-place sensors on the previous battery rack, saving a large number of in-place sensors and wiring harnesses, reducing the difficulty of debugging and saving costs.

[0079] The present application also proposes a power battery charging method.

[0084] S1001, obtaining position information of a fork module.

[0085] S1002: When the position information of the shift fork module indicates that the shift fork module is located at the origin, control the shift fork module to move in a preset direction.

[0086] As an example, the preset direction includes a first horizontal direction and a second horizontal direction, the first horizontal direction and the second horizontal direction are opposite, the fork module includes a first fork sub-module and a second fork sub-module, and controlling the fork module to move in the preset direction to transport the power battery includes: controlling the first fork sub-module to move in the first horizontal direction to transport the power battery; or controlling the second fork sub-module to move in the second horizontal direction to transport the power battery.

[0087] As an example, the first fork submodule includes a first primary fork and a first secondary fork, and controlling the first fork submodule to move in a first horizontal direction to transport the power battery includes: controlling the first secondary fork and the first primary fork to move in the first horizontal direction to transport the power battery.

[0088] As an example, Fig.11 As shown, the preset distance includes a first preset distance and a second preset distance, and the power battery charging method further includes:

[0089] S1101, obtaining a first moving distance of a first-level shifting fork and a second moving distance of a first-level shifting fork.

[0090] S1102: When the first moving distance is the first preset distance and the second moving distance is the second moving distance, control the charging interface to charge the power battery.

[0091] As an example, the second fork submodule includes a second-level fork, a second-level fork and a third-level fork, and controlling the second fork submodule to move in a second horizontal direction to transport the power battery includes: controlling the second-level fork, the second-level fork and the third-level fork to move in the second horizontal direction to transport the power battery.

[0092] As an example, Fig.12 As shown, the preset distance includes a third preset distance, a fourth preset distance, and a fifth preset distance, and the power battery charging method further includes:

[0093] S1201, obtaining a third moving distance of the second primary shift fork, a fourth moving distance of the second secondary shift fork, and a fifth moving distance of the third secondary shift fork.

[0094] S1202: When the third moving distance is the third preset distance, the fourth moving distance is the fourth preset distance, and the fifth moving distance is the fifth preset distance, control the charging interface to charge the power battery.
