[0053] The present invention is further described below by way of examples, but the present invention is not limited to the scope of the examples.

[0054] Example 1 This embodiment provides a transmission deceleration detection system for battery transportation in a battery swap station. Figure 1-Figure 6The battery swap station includes a battery swap area 880 and a battery rack 881. The battery swap area is provided with a battery swap device 60 for disassembling and assembling batteries of a battery swap vehicle. The transmission deceleration detection system includes: a battery transfer conveyor line 10, a detection unit provided on the battery transfer conveyor line 10 and the battery 70 for cooperating with a trigger unit installed on the battery of the battery swap vehicle. The detection unit is provided at a position on the battery transfer conveyor line at a preset distance from the stop position of the battery. When the detection unit detects the trigger unit, transmission deceleration information is generated. The battery transfer conveyor line 10 is used to transfer the battery 70 between the battery swap area 880 and the battery rack 881. The battery rack 881 is used to store the battery 70 and charge the battery 70 in a low-power state. The specific process is as follows: when the battery swap vehicle enters the battery swap area 880, the battery swap device 60 performs a battery removal operation, removes the exhausted battery from the battery swap vehicle, and transfers it to the battery transfer conveyor line 10. The exhausted battery is transported to the corresponding position of the battery rack at the end through the battery transfer conveyor line 10, and finally the stacker in the battery rack transfers the exhausted battery to the battery compartment for charging. Similarly, after the fully charged battery is taken out of the battery compartment, it is also transported to the position corresponding to the battery swap device 60 through the battery transfer conveyor line 10, so that the battery swap device 60 can install the fully charged battery on the battery swap vehicle.

[0055] Based on the above battery replacement process, in order to realize accurate, efficient, stable and safe transportation of the battery 70 (i.e. the above low-power battery or fully-charged battery), during the transportation of the battery 70, when the detection unit detects the trigger unit, the transmission deceleration information is generated. The generated transmission deceleration information is used to control the transportation deceleration of the battery 70 to ensure that the battery 70 is stably and safely transported to the correct position.

[0056] Based on the transmission deceleration detection system, the battery is transported through the battery transfer conveyor line, and the battery swapping equipment only needs to perform battery disassembly and installation operations in the battery swapping area, which simplifies the structure of the original battery swapping equipment in the battery swapping station and greatly reduces the equipment cost; and reduces the control complexity and accuracy of the corresponding walking control, positioning control, etc., and performs battery transfer operations through the battery transfer conveyor line. The structure is simple, the overall control is simple and reliable, and the positioning operation is easier to achieve through deceleration control, thereby reducing the equipment cost; and, in the battery transfer and transportation process, based on the detection unit provided on the battery transfer conveyor line and the battery for cooperating with the trigger unit installed on the battery of the battery swapping vehicle, the detection unit is provided on the battery transfer conveyor line at a preset distance from the stop position of the battery, and when the detection unit detects the trigger unit, it generates transmission deceleration information, which can accurately detect whether the battery is decelerated for transmission, thereby improving the accuracy, stability and safety of battery transmission.

[0057] The battery transfer conveyor line 10 is provided with a change point 8801 and an exchange point 8811. The change point 8801 is provided at a position corresponding to the battery exchange device 60, and the exchange point 8811 is provided at a position corresponding to the battery rack 881. Figure 2 , the battery transport conveyor line 10 runs through the battery exchange area 880 and extends to both sides. In another optional embodiment, the battery transport conveyor line 10 runs through the battery exchange area 880 and extends to one side.

[0058] The battery is disassembled and assembled at the corresponding position of the battery swapping equipment, and the battery is exchanged at the corresponding position of the battery rack. By setting the exchange position corresponding to the battery swapping equipment and the exchange position corresponding to the battery rack on the battery transfer conveyor line, the battery conveying position can be quickly and accurately controlled, thereby improving the battery conveying efficiency and conveying stability.

[0059] Reference Figure 2 , Figure 3 , Figure 4 , the battery exchange device 60 can be raised and lowered. In another optional embodiment, the battery transfer conveyor line can be raised and lowered.

[0060] The detection unit includes a first detection member 91 arranged at a preset rear position along the battery conveying direction at the exchange position 8801, where the "battery conveying direction" refers to the direction in which a fully charged battery is conveyed from the battery rack 881 to the battery exchange area 880. The detection unit also includes a second detection member 94 arranged at a preset rear position along the battery conveying direction at the exchange position 8811, where the "battery conveying direction" refers to the direction in which a low-charged battery is conveyed from the battery exchange area 880 to the battery rack 881. The first detection member 91 and the second detection member 94 are respectively arranged at corresponding positions along the battery conveying direction at the exchange position and the exchange position. The trigger unit includes a trigger member 92 corresponding to the first detection member 91 and the second detection member 94. The first detection member may be at least one of an infrared sensor, a contact sensor, a proximity sensor, and a visual sensor. The second detection member may be at least one of an infrared sensor, a contact sensor, a proximity sensor, and a visual sensor.

[0061] By arranging a triggering member on the battery and corresponding to the first detecting member and the second detecting member, the corresponding detecting member is accurately triggered to generate transmission deceleration information, which facilitates transmission deceleration control during battery transportation.

[0062] The first detection member and the second detection member are respectively arranged at corresponding positions of the potential change position and the exchange position along the battery conveying direction. In this way, only one trigger member is arranged on the battery to complete the detection of whether the battery reaches the exchange position and the potential change position, making the battery structure simple.

[0063] The battery swapping equipment or battery transfer conveyor line can be raised or lowered, which makes it easy to transfer the battery to the battery swapping equipment after the battery is transported, providing convenience for battery swapping; further, a first detection element is set at a preset position behind the battery swapping point along the battery conveying direction, and during the battery's transportation toward the battery swapping point, it can accurately detect whether the battery has reached a position at a preset distance from the stopping position of the battery and perform precise transmission deceleration control.

[0064] As an optional embodiment, the battery transfer conveyor line 10 is a conveyor roller battery transfer conveyor line. The conveyor roller battery transfer conveyor line includes: a roller 100, and the roller 100 is rotatably arranged along the transmission direction of the battery 70.

[0065] The conveyor roller battery transfer conveyor line also has an avoidance area, so as to avoid the space for the battery exchange equipment 60 to rise and fall and move; when the battery exchange equipment 60 is extended relative to the transmission surface of the drum 100, the battery 70 can be removed or installed according to working conditions; when the battery exchange equipment 60 is located below the transmission surface of the drum 100, the battery 70 can be transferred to the specified position under the action of the drum 100.

[0066] In a specific implementation, a battery transfer conveyor line may have a plurality of rollers 100, and the rollers 100 are parallel to each other to form a transmission surface, and the battery 70 may be arranged on the rollers 100; the rollers 100 may rotate around their own axes, and the battery 70 may move under the rotation of the rollers 100; and, by controlling the rotation direction of the rollers 100, the movement of the battery 70 may be controlled, thereby realizing the transmission of the battery 70 between the battery rack and the battery exchange area 880.

[0067] When the conveyor roller battery transfer conveyor line transfers the battery from the battery rack to the battery replacement area 880, when the first detection member 91 detects the trigger member 92, a transmission deceleration information is generated. The main control unit controls the battery transfer conveyor line 10 to reduce the conveying speed according to the information transmitted in place, and conveys the battery at a preset speed to ensure the accuracy, stability and safety of the conveying.

[0068] As an optional embodiment, the positions of the first detection member 91 and the second detection member 94 can be set according to the conveying length of the battery transport conveyor line, so that there is a relatively long fast conveying section and a relatively short deceleration conveying section during the battery conveying process. The positions of the first detection member 91 and the second detection member 94 can also be reasonably set according to the battery conveying speed of the battery transport conveyor line to ensure the safety and stability of the battery conveying process.

[0069] The battery transport conveyor line 10 has a stop mechanism arranged on at least one side of the potential change and / or exchange position along the conveying direction to limit the battery at the potential change and / or exchange position.

[0070] As an optional embodiment, a transmission in place detection device is provided at the corresponding positions of the potential change and the exchange position. The transmission in place detection device includes a sensing component and a matching component arranged in pairs on the battery transfer conveyor line and the battery, and generates transmission in place information when the sensing component detects the matching component. A first sensing component 95 is provided at the corresponding position of the potential change, and a second sensing component 96 is provided at the corresponding position of the exchange position. In order to simplify the system structure, the matching component on the battery reuses the trigger component 92. When the first sensing component 95 senses the trigger component 92, it indicates that the battery has reached the target position of the potential change, and the battery exchange operation can be accurately implemented. At this time, the first sensing component 95 generates transmission in place information. When the second sensing component 96 senses the trigger component 92, it indicates that the battery has reached the target position of the exchange position, and the battery exchange operation can be accurately implemented. At this time, the second sensing component 96 generates transmission in place information.

[0071] As a preferred embodiment, the battery transfer conveyor line also includes a stopping mechanism, which is arranged relative to the battery exchange area 880 and is used to limit the movement of the battery 70 along the transmission direction so that the battery 70 is located on the battery exchange area 880.

[0072] In specific implementation, the stopping mechanism can be implemented in a variety of ways, such as using a device with a stopper to limit the position, or by detecting the position of the battery 70 and controlling the rotation of the drum 100 to limit the position; or by using a stopper and controlling the rotation speed of the drum 100 to limit the position at the same time.

[0073] As a preferred implementation method, Figure 6 and Figure 7 As shown, the stopping mechanism is a stopper 510, and the stopper 510 is arranged on at least one side of the battery exchange area 880 along the transmission direction. In a specific implementation, a stopper 510 can be provided at both ends of the battery exchange area 880. In addition, the stopper 510 can also be provided on the side of the battery exchange area 880 away from the battery rack, or can be provided at the end of the battery rack. It can be specifically fixed on the battery transfer conveyor line, or a separate rack can be provided, and the position of the stopper 510 can achieve the stopping of the battery 70.

[0074] When the battery transfer conveyor line is in the working condition of installing the battery 70, after the battery 70 is transferred to the battery replacement area 880, the stopper 510 rises to limit the battery 70 from continuing to move; When the battery transfer conveyor line is in the state of disassembling the battery 70, the stopper 510 descends to allow the battery 70 to be transported and moved.

[0075] As a preferred implementation, the stopping mechanism further includes a stopping connection piece, which is connected to the stopping device 510 and is used to fix the stopping device 510 relative to the battery exchange area 880 .

[0076] like Figure 7As shown, the stopper 510 includes a lifting drive mechanism, a third detection member and a blocking unit 511, and the third detection member is used to sense the battery 70 to generate status information for judging the status of the stopper mechanism. The first sensing component 95 transmits the detected transmission in place information to the lifting drive mechanism; the blocking unit 511 is connected to the lifting drive mechanism, and the lifting drive mechanism is used to drive the blocking unit 511 to move up and down according to the status information. If the first sensing component 95 does not detect the battery 70, the first sensing component 95 sends out the first status information, and the lifting drive mechanism drives the blocking unit to be in a lower position according to the first status information, and does not block the battery; if the first sensing component 95 detects the battery 70, the first sensing component 95 sends out the transmission in place information, and the lifting drive mechanism drives the blocking unit to rise according to the transmission in place information to block the battery. The third detection member can be at least one of an infrared sensor, a proximity sensor and a visual sensor. Among them, the lifting direction of the blocking unit 511 can be a direction perpendicular to the transmission direction of the battery 70. When the third detection component senses the trigger component 92 on the battery 70, indicating that the battery has reached the position corresponding to the stop mechanism, the third detection component generates second state information, indicating that the stop mechanism is in a state of rising gear to stop the battery; when the third detection component does not sense the trigger component 92 on the battery 70, indicating that the battery has not reached the position corresponding to the stop mechanism, the third detection component generates third state information, indicating that the stop mechanism is in a state of retracting and not stopping the battery.

[0077] As another preferred embodiment, the stop mechanism is a first sensor and a limit detection element disposed on the battery 70. In a specific implementation, the first sensor can be at least one of an infrared sensor, a contact sensor, a proximity sensor, and a visual sensor.

[0078] When the first sensor detects the limit detection element, the first sensor sends a signal to the driving unit of the drum 100 , and the driving unit controls the drum 100 to stop rotating, thereby enabling the battery 70 to stay on the battery exchange area 880 .

[0079] As a preferred embodiment, the battery transfer conveyor line includes a plurality of roller transmission components 110, each roller transmission component 110 is extended along the transmission direction, and the plurality of roller transmission components 110 are spaced apart perpendicular to the transmission direction.

[0080] like Figure 6 As shown, the battery transfer conveyor line includes two sets of roller transmission assemblies 110, which are arranged at intervals and together form a transmission surface for the battery 70. When the battery 70 is transmitted, the battery 70 is arranged above the two sets of roller transmission assemblies 110 and moves under the action of the two sets of roller transmission assemblies 110.

[0081] In a specific implementation, the battery transfer conveyor line may also use a group of roller 100 transmission units, and the two ends of the battery 70 extend beyond the two ends of the roller 100 in the roller 100 transmission unit.

[0082] As a preferred implementation method, Figure 6 As shown, a first avoidance area 210 is formed between multiple groups of roller transmission assemblies 110 arranged at intervals; and / or, a second avoidance area 220 is provided between the rollers 100 in the roller transmission assembly 110. The first avoidance area 210 and the second avoidance area 220 enable the corresponding disassembly and assembly structure on the battery exchange device 60 to move relative to the transmission surface of the battery 70, and provide a disassembly and assembly space for the battery 70.

[0083] Rollers are provided in the transmission direction of the battery, and the battery can be transmitted between the battery rack and the battery exchange area 880 through the rollers. In addition, the transmission device also has an avoidance area to avoid the lifting and moving space of the battery exchange equipment; when the battery exchange equipment is extended relative to the transmission surface of the roller, the battery can be removed or installed according to the working conditions; when the battery exchange equipment is located below the transmission surface of the roller, the battery can be transmitted to the specified position under the action of the roller.

[0084] In a specific implementation, the battery exchange device 60 has a disassembly structure corresponding to the battery 70 mounting frame of the electric vehicle, through which the battery 70 can be removed from the electric vehicle or installed on the electric vehicle. A corresponding avoidance area can be set according to the disassembly structure, so that the disassembly structure on the battery exchange device 60 can pass through the avoidance area to disassemble and assemble the battery 70.

[0085] As a preferred implementation method, Figure 6 As shown, the roller transmission assembly 110 includes a first roller transmission unit 111 and a second roller transmission unit 112 arranged along the transmission direction; the first roller transmission unit 111 and the second roller transmission unit 112 are driven by a first roller driving unit and a second roller driving unit respectively; the first roller transmission unit 111 and the second roller transmission unit 112 are respectively arranged on both sides of the battery exchange area along the transmission direction.

[0086] The roller transmission assembly 110 also includes a third roller transmission unit 114 disposed on the battery exchange area, and the third roller transmission unit 114 is driven by a third roller driving unit.

[0087] The above-mentioned first roller transfer unit 111, second roller transfer unit 112 and second roller transfer unit 112 can be driven by corresponding driving mechanisms respectively, so that the disassembled old batteries can be transferred to the battery rack on one side of the battery exchange area, and the new batteries in the battery rack on the other side of the battery exchange area can be transferred to the battery exchange area at the same time, and the transmission speeds of the new and old batteries can be controlled separately to avoid interference in the movement of the two batteries and improve the battery replacement efficiency; they can also be driven by the same driving mechanism.

[0088] In a specific implementation, a single roller transmission assembly 110 may include a first roller transmission unit 111, a second roller transmission unit 112 and a third roller transmission unit 114 with the same basic structure, wherein the third roller transmission unit 114 may be located in the battery exchange area, and the first roller transmission unit 111 and the second roller transmission unit 112 may be located on both sides of the battery exchange area, so that the battery 70 may be transferred to the third roller transmission unit 114 under the action of the first roller transmission unit 111 or the second roller transmission unit 112, so as to provide the battery exchange equipment 60 with corresponding disassembly and assembly operations; when the corresponding operation is completed, for example, when the battery 70 on the electric vehicle is disassembled from the third roller transmission unit 114, the third roller transmission unit 114 may also transfer the battery 70 to the first roller transmission unit 111 or the second roller transmission unit 112 and then to the battery rack.

[0089] There is a second avoidance area 220 between the first roller transfer unit 111 and the third roller transfer unit 114, and / or there is a third avoidance area 230 between the second roller transfer unit 112 and the third roller transfer unit 114. The second avoidance area 220 and the third avoidance area 230 are both used for the battery exchange equipment 60 to be raised and lowered to support the battery 70.

[0090] As a preferred embodiment, the roller transmission assembly 110 includes a mounting bracket 113 and a roller 100 , both ends of the roller 100 are respectively mounted on corresponding mounting brackets 113 , and the surface of the roller 100 protrudes from the top surface of the mounting bracket 113 .

[0091] In a specific implementation, the top surface of the outer mounting bracket 113 is higher than the surface of the drum 100, and the top surface of the inner mounting bracket 113 is lower than the surface of the drum 100, so that the drum 100 protrudes from the top surface of the mounting bracket 113. Alternatively, the top surfaces of the inner and outer mounting brackets 113 are lower than the surface of the drum 100, so that the drum 100 protrudes from the top surface of the mounting bracket 113. Among them, the outer mounting bracket 113 refers to the mounting bracket 113 close to the end surface of the battery 70, and the inner mounting bracket 113 refers to the mounting bracket 113 covered by the battery 70.

[0092] As a preferred embodiment, the plurality of rollers 100 are evenly spaced apart, and the distance between two adjacent rollers 100 is less than half of the width of the battery 70 .

[0093] During the process of transporting the battery from the battery rack to the battery exchange area 880, if the first detection member 91 detects the trigger member 92, at this time, the battery is close to the target position on the exchange point where accurate battery exchange can be implemented, so the first detection member 91 generates transmission deceleration information, and according to the transmission deceleration information, controls the battery transfer conveyor line to decelerate, that is, switches to the preset speed range. The preset speed range is a relatively low speed. In this way, the stability of battery transportation can be guaranteed to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the first sensing component 95 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange point where accurate battery exchange can be implemented, so the first sensing component 95 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop transporting the battery. In order to further position the battery, the corresponding exchange point stop mechanism is also controlled to start based on the transmission in place information to stop the battery and position the battery.

[0094] Similarly, in the process of conveying the battery from the battery exchange area 880 to the battery rack, if the second detection member 94 detects the trigger member 92, at this time, the battery is close to the target position on the exchange position where the battery exchange can be accurately implemented, so the second detection member 94 generates transmission deceleration information, and controls the battery transfer conveyor line to decelerate according to the transmission deceleration information, that is, switches to the preset speed range. The preset speed range is a relatively low speed. In this way, the stability of battery transportation can be guaranteed to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the second sensing component 96 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange position where the battery exchange can be accurately implemented, so the second sensing component 96 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop conveying the battery. In order to further position the battery, the stop mechanism corresponding to the exchange position is controlled to start based on the transmission in place information to stop the battery and position the battery.

[0095] This embodiment also provides a transmission deceleration detection method for battery transport. The transmission deceleration detection method is applied to the battery swapping process at a battery swapping station. Figure 8 The battery transport transmission deceleration detection method comprises the following steps: Step S441, based on the battery replacement instruction, control the battery transfer conveyor line to start and perform battery transfer.

[0096] Step S442: Control the battery transfer conveyor line to decelerate based on the transmission deceleration information.

[0097] The batteries are transported through a battery transfer conveyor line, which has a simple structure and simple and reliable overall control. It simplifies the control complexity and accuracy of the walking control, positioning control, etc. of the original battery swap equipment in the battery swap station, reduces the equipment cost, and makes the positioning operation easier to achieve. Specifically, during the battery transportation process, the battery transfer conveyor line is controlled to decelerate and transport the battery based on the transmission deceleration information, which can improve the stability, accuracy and safety of battery transportation.

[0098] In specific implementation, when a battery swap instruction is received, the battery transfer conveyor line is controlled to start and perform battery transfer. When the battery swap instruction is to transfer a low-power battery, the battery transfer conveyor line is controlled to move away from the battery swap area 880; when the battery swap instruction is to transfer a fully charged battery, the battery transfer conveyor line is controlled to move toward the battery swap area 880.

[0099] By properly setting the transport direction according to the low-power or fully-charged property information of the battery and the specific operations of the battery replacement process, accurate transport of the battery can be achieved and the flexibility of control can be improved.

[0100] In an optional embodiment, when there are battery racks on both sides of the battery transfer conveyor line, the battery transfer conveyor line is controlled to transport the low-charged batteries toward the battery rack on the other side opposite to the battery rack where the selected fully-charged batteries are located.

[0101] When there are battery racks on both sides of the battery transfer conveyor line, the fully charged batteries are transported in the direction of the battery exchange area 880 to facilitate battery installation operations, and the battery exchange efficiency is improved while achieving accurate battery transportation.

[0102] As an optional embodiment, during the process of transporting the battery from the battery rack to the battery exchange area 880, if the first detection member 91 detects the trigger member 92, at this time, the battery is close to the target position on the exchange point where accurate battery exchange can be implemented, so the first detection member 91 generates transmission deceleration information, and according to the transmission deceleration information, controls the battery transfer conveyor line to decelerate, that is, switches to a preset speed range. The preset speed range is a relatively low speed. This can ensure the stability of battery transportation to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the first sensing component 95 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange point where accurate battery exchange can be implemented, so the first sensing component 95 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop transporting the battery. In order to further position the battery, the corresponding exchange point stop mechanism is also controlled to start based on the transmission in place information to stop the battery and position the battery.

[0103] Similarly, in the process of conveying the battery from the battery exchange area 880 to the battery rack, if the second detection member 94 detects the trigger member 92, at this time, the battery is close to the target position on the exchange position where the battery exchange can be accurately implemented, so the second detection member 94 generates transmission deceleration information, and controls the battery transfer conveyor line to decelerate according to the transmission deceleration information, that is, switches to the preset speed range. The preset speed range is a relatively low speed. In this way, the stability of battery transportation can be guaranteed to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the second sensing component 96 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange position where the battery exchange can be accurately implemented, so the second sensing component 96 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop conveying the battery. In order to further position the battery, the stop mechanism corresponding to the exchange position is controlled to start based on the transmission in place information to stop the battery and position the battery.

[0104] A stopping mechanism is provided on at least one of the front and rear sides along the battery conveying direction, and the stopping mechanism is used to further ensure that the battery is transmitted in place. The stopping mechanism is controlled to start based on the battery replacement instruction and the transmission in place information generated by the first sensor or the second sensor to position the battery. The stopping mechanism can be started timely and effectively to position the battery, thereby improving the accuracy of battery transmission.

[0105] In an optional embodiment, when the battery is delivered to the battery exchange point, the battery exchange equipment is controlled to lift and obtain the battery on the battery exchange point to perform the battery installation operation.

[0106] In another optional embodiment, when the battery is transported to the battery exchange point, the battery transfer conveyor line is controlled to descend and the battery exchange equipment is enabled to obtain the battery on the battery exchange point to perform the battery installation operation.

[0107] In an optional embodiment, when the battery is delivered to the exchange position, the palletizer is controlled to extend and obtain the low-power battery located at the exchange position so as to place the low-power battery into a designated battery storage position.

[0108] After the battery transfer conveyor line transports the fully charged battery to the battery swapping point and it is in place, the battery swapping equipment can obtain the fully charged battery by controlling the battery swapping equipment to lift or the battery transfer conveyor line to lower. At this time, the fully charged battery is separated from the battery transfer conveyor line, which makes it easier for the battery swapping equipment to perform battery installation operations, simplifying the transfer process of the fully charged battery before installation and improving the battery swapping efficiency.

[0109] Example 2 This embodiment provides a transmission deceleration detection system for battery transport. The difference between the transmission deceleration detection system for battery transport in this embodiment and the transmission deceleration detection system for battery transport in Example 1 is that in this embodiment, the battery transport conveyor line is a double-speed chain battery transport conveyor line.

[0110] Reference Figure 9-13 The double-speed chain battery transfer conveyor line 11 is based on the double-speed chain structure. The double-speed chain can refer to a material conveying machine that uses a chain as a traction and carrier. It is a type of conveyor that can transport bulky items at one time. In this embodiment, by setting the double-speed chain battery transfer conveyor line 11, fully charged batteries or low-charged batteries can be directly transported between the battery rack and the battery exchange area 880 on the double-speed chain battery transfer conveyor line 11. This solution reduces the number of electronic control components, greatly reduces costs, and also simplifies the control process. In addition, the double-speed chain battery transfer conveyor line can select the running speed of the chain, and use the speed-increasing function of the double-speed chain to enable the battery 70 supported thereon to run quickly; the conveying capacity is large and can carry large load batteries; the conveying speed is accurate and stable, which can ensure the precise synchronous conveying of the batteries.

[0111] The battery transfer conveyor line 11 of the double-speed chain is provided with a change point and an exchange position. The change point is provided at the corresponding position of the battery exchange equipment, and the exchange position is provided at the corresponding position of the battery rack 881. A detection unit is provided on the battery transfer conveyor line 11 of the double-speed chain, and a trigger unit is provided on the battery. As an optional embodiment, the detection unit includes a first detection member 91 and a second detection member 94, and the first detection member and the second detection member are respectively arranged at the corresponding positions of the change point and the exchange position along the battery conveying direction. The first detection member 91 is arranged at a preset rear position along the battery conveying direction at the change point 8801; the second detection member 94 is arranged at a preset rear position along the battery conveying direction at the exchange position 8811. The trigger unit includes a trigger member 92 arranged on the battery. The first detection member can be at least one of an infrared sensor, a proximity sensor and a visual sensor. The second detection member can be at least one of an infrared sensor, a proximity sensor and a visual sensor.

[0112] As an optional embodiment, a transmission in place detection device is provided at the corresponding positions of the potential change and the exchange position. The transmission in place detection device includes a sensing component and a matching component arranged in pairs on the battery transfer conveyor line and the battery, and generates transmission in place information when the sensing component detects the matching component. A first sensing component 95 is provided at the corresponding position of the potential change, and a second sensing component 96 is provided at the corresponding position of the exchange position. In order to simplify the system structure, the matching component on the battery reuses the trigger component 92. When the first sensing component 95 senses the trigger component 92, it indicates that the battery has reached the target position of the potential change, and the battery exchange operation can be accurately implemented. At this time, the first sensing component 95 generates transmission in place information. When the second sensing component 96 senses the trigger component 92, it indicates that the battery has reached the target position of the exchange position, and the battery exchange operation can be accurately implemented. At this time, the second sensing component 96 generates transmission in place information.

[0113] In an optional embodiment, the battery exchange equipment can be raised and lowered. In another optional embodiment, the battery transfer conveyor line can be raised and lowered.

[0114] The double-speed chain battery transfer conveyor line 11 may include a stop mechanism 12, which is arranged on the double-speed chain battery transfer conveyor line 11 and is used to limit the movement of the battery 70. The stop mechanism 12 is arranged on the double-speed chain battery transfer conveyor line 11 and can limit the movement of the battery 70 in the conveying direction along the double-speed chain battery transfer conveyor line 11.

[0115] In one embodiment, a stop mechanism 12 is provided on the side of the battery exchange area 880 away from the battery rack. The stop mechanism 12 is provided on the side of the battery exchange area 880 away from the battery rack, and enables the battery 70 to be docked on the battery exchange area 880, thereby facilitating the subsequent replacement of the battery 70 on the battery exchange area 880.

[0116] In one embodiment, the end of the battery rack may also be provided with a stop mechanism 12. The stop mechanism 12 is provided at the end of the battery rack, and can allow the battery 70 to rest on the battery rack, thereby facilitating the subsequent movement of the battery 70 to the battery rack.

[0117] In one embodiment, the stop mechanism 12 has a driving part and a stop part, and the driving part is used to drive the stop part to rise and fall in a direction perpendicular to the plane where the double-speed chain battery transfer conveyor line 11 is located. Among them, by setting the stop part to be liftable, on the one hand, it is possible to stop the fully charged battery, and on the other hand, it is possible to avoid the low-charged battery (or other components such as the battery tray) that needs to continue to move forward. For example, when the battery 70 is being installed, that is, the double-speed chain battery transfer conveyor line 11 carries a fully charged battery to be replaced with the low-charged battery of the vehicle, the battery 70 is transferred to the preset position of the battery replacement area 880, and the driving part drives the stop part to rise to allow the battery 70 to dock and complete the installation process; when the battery 70 is being removed from the vehicle, that is, the battery 70 removed from the vehicle is located on the double-speed chain battery transfer conveyor line 11, the driving part drives the stop part to descend to avoid the low-charged battery and allow the low-charged battery to continue to be transported to the battery rack.

[0118] It should be noted that, in the present embodiment, the stopper stops the battery 70 by lifting and lowering, and in other alternative embodiments, the stopper may adopt other stopper methods. For example, the driving unit is used to drive the stopper to flip onto the speed chain battery conveyor line 11 or flip out of the speed chain battery conveyor line 11. Accordingly, the stopper is set to be flippable, and when the stopper flips to a position higher than the contact surface between the speed chain battery conveyor line 11 and the battery 70, the battery 70 can be limited so that the battery 70 stops moving forward, and when the stopper flips to a position not higher than (flips out of) the contact surface between the speed chain battery conveyor line 11 and the battery 70, the battery can be avoided so that the battery 70 continues to move forward. For example, flipping from a conveying direction perpendicular to the speed chain battery transport conveyor line 11 to a conveying direction parallel to the speed chain battery transport conveyor line 11 can stop fully charged batteries and avoid depleted batteries that need to continue to move forward.

[0119] In one embodiment, the speed chain battery transport conveyor line 11 is provided with a first sensing component 95 adjacent to the battery exchange area 880. The first sensing component 95 can be one or more of a weight sensor, a limit sensor, a contact sensor, etc. The first sensing component 95 is communicatively connected to the control unit of the stop mechanism 12. The first sensing component 95 is used to send a signal to the control unit after detecting that the battery 70 is approaching, so that the control unit controls the drive unit to drive the stop unit to lift or flip. By providing the first sensing component 95 and the control unit, when a battery 70 approaches or enters the battery exchange area 880, it can be ensured that the drive unit can promptly control the lifting or flipping of the stop unit.

[0120] In one embodiment, the double-speed chain battery transport conveyor line 11 is provided with a second sensing component 96 adjacent to the battery rack. The second sensing component 96 is connected to the control unit of the stop mechanism 12 for communication. The second sensing component 96 is used to send a signal to the control unit after detecting the approach of the battery 70, so that the control unit controls the drive unit to drive the stop unit to rise, fall or flip. By providing the second sensing component 96 and the control unit, when a battery 70 approaches or enters the battery rack, it can be ensured that the drive unit controls the rise, fall or flip of the stop unit in time.

[0121] As an optional embodiment, the stop mechanism is provided with a third detection member, which is used to sense the battery 70 to generate status information for determining the state of the stop mechanism. When the third detection member senses the trigger member 92 on the battery 70, indicating that the battery has reached the position corresponding to the stop mechanism, the third detection member generates the second status information, indicating that the stop mechanism is in the state of the battery being stopped at the rising gear; when the third detection member does not sense the trigger member 92 on the battery 70, indicating that the battery has not reached the position corresponding to the stop mechanism, the third detection member generates the third status information, indicating that the stop mechanism is in the state of being retracted and not stopping the battery.

[0122] The double-speed chain battery transfer conveyor line 11 may include a guide positioning mechanism, which is arranged on both sides of the double-speed chain battery transfer conveyor line 11. The guide positioning mechanism is used to guide and position the battery 70 so that the battery 70 moves along a preset path on the double-speed chain battery transfer conveyor line 11. By setting the guide positioning mechanism, the movement of the battery 70 can be guided. The guide positioning mechanism is arranged on both sides of the double-speed chain battery transfer conveyor line 11, which avoids the battery 70 from tilting relative to the conveying direction and improves the stability during the movement.

[0123] Specifically, the guiding and positioning mechanism includes two mutually parallel positioning plates 13, and the two positioning plates 13 are respectively located on both sides of the double-speed chain battery transfer conveyor line 11; the positioning plate 13 includes a main body 131 and a guiding part 132, and the two ends of the main body 131 are respectively provided with guiding parts 132, and the side of the guiding part 132 close to the battery 70 forms an angle with the extension direction of the main body 131, and the spacing between the two opposite guiding parts 132 gradually increases in the direction away from the main body 131 to guide the battery 70. Among them, by providing the guiding part 132, even if a certain amount of offset occurs between the battery 70 and the main body 131 during the transmission process, it can still enter the guiding and positioning mechanism through the guiding effect of the guiding part 132, thereby effectively avoiding the problem that the battery 70 cannot smoothly enter the guiding and positioning mechanism due to the inability to accurately align the battery 70 with the main body 131.

[0124] The guiding and positioning mechanism may include a first guiding and positioning mechanism, which is arranged at a position of the battery transfer conveying line 11 of the double-speed chain close to the battery exchange area 880. The first guiding and positioning mechanism is arranged at a position of the battery transfer conveying line 11 of the double-speed chain close to the battery exchange area 880, and can guide the battery 70 when it enters the battery exchange area 880, so as to ensure that the battery 70 enters the battery exchange area 880 smoothly.

[0125] The first guide positioning mechanism may also be provided in the battery replacement area 880, and is used to make the battery 70 correspond to the position of the vehicle corresponding to the replacement of the battery 70 in the driving direction of the vehicle. The first guide positioning mechanism is provided in the battery replacement area 880, and is used to accurately position the battery 70, so that the battery 70 accurately enters the preset position corresponding to the replacement of the battery 70 of the vehicle, thereby facilitating the subsequent replacement thereof.

[0126] The guiding and positioning mechanism may also include a second guiding and positioning mechanism, which is arranged along the path of the double-speed chain battery transfer conveyor line 11. The second guiding and positioning mechanism can guide the battery 70 during the transmission between the battery exchange area 880 and the battery rack to avoid the battery 70 from being offset and ensure the accuracy of its transportation path.

[0127] The double-speed chain battery transport conveyor line 11 may also include a driving mechanism 14 and a transmission mechanism 15, wherein the input end of the transmission mechanism 15 is connected to the driving mechanism 14, and the output end of the transmission mechanism 15 is connected to the double-speed chain battery transport conveyor line 11. The driving mechanism 14 provides a stable driving force to the transmission mechanism 15, so that the output of the transmission mechanism 15 is more stable, thereby making the movement of the double-speed chain more stable, and improving the stability of the entire system. The driving mechanism 14 can flexibly select one of a motor, a cylinder, a screw rod, and an electric push rod according to actual needs.

[0128] In one embodiment, the double-speed chain battery transfer conveyor line 11 may include two double-speed chain battery conveyor rails 181, which are arranged opposite to each other and arranged on both sides of the battery exchange area 880 in a direction perpendicular to the direction of vehicle travel. Among them, by providing two double-speed chain battery conveyor rails 181, the contact area between the battery 70 and the double-speed chain battery transfer conveyor line 11 is increased, and the battery 70 is prevented from tilting relative to the double-speed chain battery conveyor rails 181, thereby improving the stability during movement. Setting the double-speed chain battery conveyor rails 181 perpendicular to the direction of vehicle travel can reduce the interference between the conveying path and the vehicle travel path, and simplify the structure of the entire system.

[0129] In another embodiment, the double-speed chain battery transfer conveyor line 11 may include four double-speed chain battery conveyor rails 181 arranged in parallel, and pass through the battery exchange area 880 in a direction perpendicular to the direction of vehicle travel. By providing four double-speed chain battery conveyor rails 181, the stability of the battery 70 during movement is further improved.

[0130] As an optional embodiment, during the process of transporting the battery from the battery rack to the battery exchange area 880, if the first detection member 91 detects the trigger member 92, at this time, the battery is close to the target position on the exchange point where accurate battery exchange can be implemented, so the first detection member 91 generates transmission deceleration information, and according to the transmission deceleration information, controls the battery transfer conveyor line to decelerate, that is, switches to a preset speed range. The preset speed range is a relatively low speed. This can ensure the stability of battery transportation to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the first sensing component 95 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange point where accurate battery exchange can be implemented, so the first sensing component 95 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop transporting the battery. In order to further position the battery, the corresponding exchange point stop mechanism is also controlled to start based on the transmission in place information to stop the battery and position the battery.

[0131] Similarly, in the process of conveying the battery from the battery exchange area 880 to the battery rack, if the second detection member 94 detects the trigger member 92, at this time, the battery is close to the target position on the exchange position where the battery exchange can be accurately implemented, so the second detection member 94 generates transmission deceleration information, and controls the battery transfer conveyor line to decelerate according to the transmission deceleration information, that is, switches to the preset speed range. The preset speed range is a relatively low speed. In this way, the stability of battery transportation can be guaranteed to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the second sensing component 96 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange position where the battery exchange can be accurately implemented, so the second sensing component 96 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop conveying the battery. In order to further position the battery, the stop mechanism corresponding to the exchange position is controlled to start based on the transmission in place information to stop the battery and position the battery.

[0132] This embodiment also provides a transmission deceleration detection method for battery transportation. In specific implementation, after receiving a battery replacement instruction, the battery transportation conveyor line is controlled to start so as to perform battery transportation. When the battery replacement instruction is to transport a low-power battery, the battery transportation conveyor line is controlled to move in a direction away from the battery replacement area 880; when the battery replacement instruction is to transport a fully charged battery, the battery transportation conveyor line is controlled to move toward the battery replacement area 880.

[0133] By properly setting the transport direction according to the low-power or fully-charged property information of the battery and the specific operations of the battery replacement process, accurate transport of the battery can be achieved and the flexibility of control can be improved.

[0134] In an optional embodiment, when there are battery racks on both sides of the battery transfer conveyor line, the battery transfer conveyor line is controlled to transport the low-charged batteries toward the battery rack on the other side opposite to the battery rack where the selected fully-charged batteries are located.

[0135] When there are battery racks on both sides of the battery transfer conveyor line, the fully charged batteries are transported in the direction of the battery exchange area 880 to facilitate battery installation operations, and the battery exchange efficiency is improved while achieving accurate battery transportation.

[0136] During the process of transporting the battery from the battery rack to the battery exchange area 880, if the first detection member 91 detects the trigger member 92, at this time, the battery is close to the target position on the exchange point where accurate battery exchange can be implemented, so the first detection member 91 generates transmission deceleration information, and according to the transmission deceleration information, controls the battery transfer conveyor line to decelerate, that is, switches to the preset speed range. The preset speed range is a relatively low speed. In this way, the stability of battery transportation can be guaranteed to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the first sensing component 95 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange point where accurate battery exchange can be implemented, so the first sensing component 95 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop transporting the battery. In order to further position the battery, the corresponding exchange point stop mechanism is also controlled to start based on the transmission in place information to stop the battery and position the battery.

[0137] Similarly, in the process of conveying the battery from the battery exchange area 880 to the battery rack, if the second detection member 94 detects the trigger member 92, at this time, the battery is close to the target position on the exchange position where the battery exchange can be accurately implemented, so the second detection member 94 generates transmission deceleration information, and controls the battery transfer conveyor line to decelerate according to the transmission deceleration information, that is, switches to the preset speed range. The preset speed range is a relatively low speed. In this way, the stability of battery transportation can be guaranteed to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the second sensing component 96 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange position where the battery exchange can be accurately implemented, so the second sensing component 96 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop conveying the battery. In order to further position the battery, the stop mechanism corresponding to the exchange position is controlled to start based on the transmission in place information to stop the battery and position the battery.

[0138] A stopping mechanism is provided on at least one of the front and rear sides along the battery conveying direction, and the stopping mechanism is used to further ensure that the battery is transmitted in place. The stopping mechanism is controlled to start based on the battery replacement instruction and the transmission in place information generated by the first sensor or the second sensor to position the battery. The stopping mechanism can be started timely and effectively to position the battery, thereby improving the accuracy of battery transmission.

[0139] In an optional embodiment, when the battery is delivered to the battery exchange point, the battery exchange equipment is controlled to lift and obtain the battery on the battery exchange point to perform the battery installation operation.

[0140] In another optional embodiment, when the battery is transported to the battery exchange point, the battery transfer conveyor line is controlled to descend and the battery exchange equipment is enabled to obtain the battery on the battery exchange point to perform the battery installation operation.

[0141] In an optional embodiment, when the battery is delivered to the exchange position, the palletizer is controlled to extend and obtain the low-power battery located at the exchange position so as to place the low-power battery into a designated battery storage position.

[0142] After the battery transfer conveyor line transports the fully charged battery to the battery swapping point and it is in place, the battery swapping equipment can obtain the fully charged battery by controlling the battery swapping equipment to lift or the battery transfer conveyor line to lower. At this time, the fully charged battery is separated from the battery transfer conveyor line, which makes it easier for the battery swapping equipment to perform battery installation operations, simplifying the transfer process of the fully charged battery before installation and improving the battery swapping efficiency.

[0143] Example 3 This embodiment provides a transmission deceleration detection system for battery transport. The difference between the transmission deceleration detection system for battery transport in this embodiment and the transmission deceleration detection system for battery transport in Example 1 is that in this embodiment, the battery transport conveyor line is a belt battery transport conveyor line 1.

[0144] Reference Fig.14 , Fig.15 , Fig.16 , the belt battery transfer conveyor line 1 at least partially extends between the battery rack 881 and the battery exchange area 880, that is, the entire belt battery transfer conveyor line 1 extends between the battery rack 881 and the battery exchange area 880, or the belt battery transfer conveyor line 1 partially extends between the battery rack 881 and the battery exchange area 880. The belt battery transfer conveyor line 1 is used to carry and drive the battery 70 to move between the battery rack 881 and the battery exchange area 880. The battery exchange area 880 is used to perform battery exchange operations on battery exchange vehicles, and the battery rack 881 is used to carry the battery 70 and / or charge the battery 70.

[0145] When in use, the battery swapping vehicle is positioned on the battery swapping area 880, the depleted batteries on the battery swapping vehicle are removed and placed on the belt battery transfer conveyor line 1, and the belt battery transfer conveyor line 1 transports the depleted batteries to the battery rack 881 for storage; the fully charged batteries on the battery rack 881 are placed on the belt battery transfer conveyor line 1 and transported to the battery swapping area 880 via the belt battery transfer conveyor line 1, so that the fully charged batteries can be installed in the battery swapping vehicle. This embodiment sets up the belt battery transfer conveyor line 1 to transport batteries, which can transport batteries accurately and at low cost.

[0146] The detection unit includes a first detection member 91 disposed at a preset rear position along the battery conveying direction at the switching position 8801. The detection unit also includes a second detection member 94 disposed at a preset rear position along the battery conveying direction at the exchange position 8811. The first detection member 91 and the second detection member 94 are disposed at corresponding positions of the switching position and the exchange position along the battery conveying direction, respectively. The trigger unit includes a trigger member 92 corresponding to the first detection member 91 and the second detection member 94. The first detection member may be at least one of an infrared sensor, a contact sensor, a proximity sensor, and a visual sensor. The second detection member may be at least one of an infrared sensor, a contact sensor, a proximity sensor, and a visual sensor.

[0147] As an optional embodiment, a transmission in place detection device is provided at the corresponding positions of the potential change and the exchange position. The transmission in place detection device includes a sensing component and a matching component arranged in pairs on the battery transfer conveyor line and the battery, and generates transmission in place information when the sensing component detects the matching component. A first sensing component 95 is provided at the corresponding position of the potential change, and a second sensing component 96 is provided at the corresponding position of the exchange position. In order to simplify the system structure, the matching component on the battery reuses the trigger component 92. When the first sensing component 95 senses the trigger component 92, it indicates that the battery has reached the target position of the potential change, and the battery exchange operation can be accurately implemented. At this time, the first sensing component 95 generates transmission in place information. When the second sensing component 96 senses the trigger component 92, it indicates that the battery has reached the target position of the exchange position, and the battery exchange operation can be accurately implemented. At this time, the second sensing component 96 generates transmission in place information.

[0148] As an optional embodiment, a first sensing component 95 is provided on the belt battery transfer conveyor line 1 for detecting whether the battery 70 moves along the battery rack 881 toward the battery exchange area 880 on the belt battery transfer conveyor line 1 and reaches the first arrival point P ( Figure 1 The dotted line indicates the situation when the battery 70 is at the first arrival point P); the first arrival point P refers to the position where the battery 70 moves to the battery swapping area 880 and is suitable for battery swapping. This position is below the battery swapping area 880. After the fully charged battery reaches this position, the fully charged battery can be installed on the battery swapping vehicle. Alternatively, the first arrival point P refers to the position where the battery 70 moves to a suitable waiting position. This position is below or to the side of the battery swapping area 880. After the fully charged battery reaches this position, its position can be further adjusted for positioning and then installed on the battery swapping vehicle. When the first sensing component 95 detects the triggering member 92 provided on the battery 70, it indicates that the battery 70 has arrived at the first arrival point P, and the first sensing component 95 generates transmission in place information to stop battery transmission.

[0149] When in use, the detection result of the first sensing component 95 can be used as a start / stop signal for related equipment in the battery swap station, and can also be used as reference data for maintenance and repair by maintenance personnel of the battery swap station.

[0150] As an optional embodiment, a second sensing component 96 is provided at the exchange position of the battery rack 881. When the second sensing component 96 detects the trigger member 92 provided on the battery 70, it indicates that the battery 70 has reached the exchange position. The second sensing component 96 generates transmission arrival information to stop the battery transmission.

[0151] In an optional embodiment, the battery exchange equipment can be raised and lowered. In another optional embodiment, the battery transfer conveyor line can be raised and lowered.

[0152] The belt battery transfer conveyor line 1 also includes a stop mechanism 3, which is used to stop the battery 70 at the first arrival point P on the belt battery transfer conveyor line 1. The stop mechanism 3 can be set on the belt battery transfer conveyor line 1 or on the battery replacement area 880. The stop mechanism 3 realizes the positioning of the battery 70 and improves the positioning accuracy of the battery 70.

[0153] The stop mechanism 3 can be raised or lowered or turned over. When in use, the stop mechanism 3 can be raised or turned over to block the battery 70, and the stop mechanism 3 can be reset to accommodate and leave space for other components. The third detection member is arranged on the stop mechanism 3, which can improve the accuracy of the detection structure of the third detection member. If the third detection member does not detect the battery 70, the third detection member sends out a first state information, and drives the stop mechanism 3 to be in a lower position according to the first state information, and does not stop the battery; if the third detection member detects the battery 70, the third detection member sends out a second state information, and drives the stop mechanism 3 to rise according to the second state information to stop the battery. The third detection member can be at least one of an infrared sensor, a proximity sensor, and a visual sensor.

[0154] When the first sensing component 95 detects that the battery 70 arrives at the first arrival point P, the transmission arrival information is generated to control the belt battery transfer conveyor line 1 to stop. In other words, the transmission arrival information is used as a signal for the belt battery transfer conveyor line 1 to stop, ensuring the accurate position of the battery 70.

[0155] A guide bar 5 is also provided on the outside of the belt battery transfer conveyor line 1. The upper surface of the guide bar 5 is higher than the surface of the belt battery transfer conveyor line 1 for supporting the battery 70. The guide bar 5 is used to guide or support the battery 70 so that the battery 70 moves with the belt battery transfer conveyor line 1. In other words, the guide bar 5 can guide the moving battery 70 to position it in one direction, and the guide bar 5 can withstand the gravity of the battery 70 transmitted via the belt.

[0156] The belt battery transfer conveyor line 1 includes a belt body 151 and at least two pulleys 152. A plurality of connected L-shaped holders 153 are provided on the surface of the belt body 151 in contact with the battery 70. The L-shaped holder 153 includes a mounting surface 1031 and a card guide surface 1032 which are perpendicular to each other. The mounting surface 1031 is arranged on the surface of the belt body 151 and is used to connect other equipment for fixation. The card guide surfaces 1032 of the plurality of connected L-shaped holders 153 are fixedly connected to the belt body 151. It should be noted that the card guide surface 1032 can be a structure with a card groove to realize the positioning of the belt body 151 in a direction perpendicular to the transportation direction of the belt battery transfer conveyor line 1.

[0157] As an optional embodiment, during the process of transporting the battery from the battery rack to the battery exchange area 880, if the first detection member 91 detects the trigger member 92, at this time, the battery is close to the target position on the exchange point where accurate battery exchange can be implemented, so the first detection member 91 generates transmission deceleration information, and according to the transmission deceleration information, controls the battery transfer conveyor line to decelerate, that is, switches to a preset speed range. The preset speed range is a relatively low speed. This can ensure the stability of battery transportation to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the first sensing component 95 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange point where accurate battery exchange can be implemented, so the first sensing component 95 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop transporting the battery. In order to further position the battery, the corresponding exchange point stop mechanism is also controlled to start based on the transmission in place information to stop the battery and position the battery.

[0158] Similarly, in the process of conveying the battery from the battery exchange area 880 to the battery rack, if the second detection member 94 detects the trigger member 92, at this time, the battery is close to the target position on the exchange position where the battery exchange can be accurately implemented, so the second detection member 94 generates transmission deceleration information, and controls the battery transfer conveyor line to decelerate according to the transmission deceleration information, that is, switches to the preset speed range. The preset speed range is a relatively low speed. In this way, the stability of battery transportation can be guaranteed to ensure that the battery arrives at the target position accurately and improves the accuracy of battery transportation. Next, when the second sensing component 96 senses the trigger member 92, it indicates that the battery has reached the target position on the exchange position where the battery exchange can be accurately implemented, so the second sensing component 96 generates transmission in place information. According to the transmission in place information, the battery transfer conveyor line is controlled to stop conveying the battery. In order to further position the battery, the stop mechanism corresponding to the exchange position is controlled to start based on the transmission in place information to stop the battery and position the battery.

[0159] This embodiment also provides a method for detecting the arrival of battery transfer. In specific implementation, after receiving a battery replacement instruction, the battery transfer conveyor line is controlled to start and thus perform battery transfer. When the battery replacement instruction is to transfer a low-power battery, the battery transfer conveyor line is controlled to move in a direction away from the battery replacement area 880; when the battery replacement instruction is to transfer a fully charged battery, the battery transfer conveyor line is controlled to move toward the battery replacement area 880.

[0160] By properly setting the transport direction according to the low-power or fully-charged property information of the battery and the specific operations of the battery replacement process, accurate transport of the battery can be achieved and the flexibility of control can be improved.

[0161] In an optional embodiment, when there are battery racks on both sides of the battery transfer conveyor line, the battery transfer conveyor line is controlled to transport the low-charged batteries toward the battery rack on the other side opposite to the battery rack where the selected fully-charged batteries are located.

[0162] When there are battery racks on both sides of the battery transfer conveyor line, the fully charged batteries are transported in the direction of the battery exchange area 880 to facilitate battery installation operations, and the battery exchange efficiency is improved while achieving accurate battery transportation.

[0163] Furthermore, in order to improve the stability of battery transportation, during the battery transportation process, when the distance between the battery and the potential change or exchange position is within a preset distance range, the battery transport conveyor line is controlled to slow down. For example, when the distance between the battery and the potential change is within a preset distance range, the battery transport conveyor line is controlled to slow down to improve the accuracy of battery transportation. When the distance between the battery and the exchange position is within a preset distance range, the battery transport conveyor line is controlled to slow down to improve the accuracy of battery transportation.

[0164] During the battery transportation process, when the distance between the battery and the replacement potential or exchange position is within a preset distance range, the battery transfer conveyor line is controlled to slow down, which can improve the stability of battery transportation.

[0165] As an optional implementation, during the battery transportation process, the stopping mechanism is controlled to start based on the battery replacement instruction and the transmission arrival information generated by the first detection member or the second detection member to position the battery.

[0166] For example, when the battery is transported to the exchange position, the first detection member detects the trigger member, and generates transmission in place information. According to the transmission in place information, the stop mechanism is activated to stop the battery, restricting the battery from moving further, and positioning the battery. When the battery is transported to the exchange position, the second detection member detects the trigger member, and generates transmission in place information. According to the transmission in place information, the stop mechanism is activated to stop the battery, restricting the battery from moving further, and positioning the battery.

[0167] A stopping mechanism is provided on at least one of the front and rear sides along the battery conveying direction, and the stopping mechanism is used to further ensure that the battery is transmitted in place. The stopping mechanism is controlled to start based on the battery replacement instruction and the transmission in place information generated by the first detection component or the second detection component to position the battery. The stopping mechanism can be started timely and effectively to position the battery, thereby improving the accuracy of battery transmission.

[0168] In an optional embodiment, when the battery is delivered to the battery exchange point, the battery exchange equipment is controlled to lift and obtain the battery on the battery exchange point to perform the battery installation operation.

[0169] In another optional embodiment, when the battery is transported to the battery exchange point, the battery transfer conveyor line is controlled to descend and the battery exchange equipment is enabled to obtain the battery on the battery exchange point to perform the battery installation operation.

[0170] In an optional embodiment, when the battery is delivered to the exchange position, the palletizer is controlled to extend and obtain the low-power battery located at the exchange position so as to place the low-power battery into a designated battery storage position.

[0171] After the battery transfer conveyor line transports the fully charged battery to the battery swapping point and it is in place, the battery swapping equipment can obtain the fully charged battery by controlling the battery swapping equipment to lift or the battery transfer conveyor line to lower. At this time, the fully charged battery is separated from the battery transfer conveyor line, which makes it easier for the battery swapping equipment to perform battery installation operations, simplifying the transfer process of the fully charged battery before installation and improving the battery swapping efficiency.

[0172] Although the specific embodiments of the present invention are described above, it should be understood by those skilled in the art that this is only for illustration and the protection scope of the present invention is defined by the appended claims. Those skilled in the art may make various changes or modifications to these embodiments without departing from the principles and essence of the present invention, but these changes and modifications all fall within the protection scope of the present invention.
