Obviously, the drawings described below are only some embodiments of the present application. For those skilled in the art, other drawings can be obtained based on these drawings without creative work.

[0023] Figure 3 It is a schematic diagram of the architecture of an automatic battery swap station according to an embodiment of the present application. DETAILED DESCRIPTION

[0024] Research has found that the reason for the low battery replacement efficiency in the existing technology is at least that the effective use area of ​​the battery replacement station in the existing technology is small, so the number of battery replacement devices accommodated is limited. When replacing batteries for multiple vehicles to be replaced, the battery boxes are likely to be insufficient, which will reduce the battery replacement efficiency.

[0025] The study also found that the reason why the power exchanger in the prior art has a short service life is that the power exchanger cannot be repaired in time when it is damaged, so its service life is short.

[0026] Therefore, the present application proposes an automatic battery swap station, which can increase the effective use area of ​​the battery swap station within a limited floor space, thereby increasing the number of battery swap devices accommodated in the battery swap station. In addition, an operation and maintenance room is added to the automatic battery swap station, which can repair and maintain the battery swap devices, so as to extend the service life of the battery swap station.

[0027] The following is a clear and complete description of the technical solution of the automatic battery swap station in the embodiment of the present application in combination with the embodiments and drawings.

The third power exchange space 3, the second power exchange space 2 and the first power exchange space 1 are connected to form a space with the same end at the beginning and the end.

[0031] In this embodiment, since the space formed by the third battery exchange space 3, the second battery exchange space 2 and the first battery exchange space 1 is a curved structure with the same end at the beginning and the end, the effective use area of ​​the automatic battery exchange station is increased, and more battery exchange appliances can be installed to improve the battery exchange efficiency. In addition, since an operation and maintenance room is provided, the operation and maintenance of the battery exchange appliances can be realized in the automatic battery exchange station, which greatly extends the service life of the battery exchange appliances.

[0032] In one embodiment, the first battery exchange space 1 and the second battery exchange space 2 are of equal length and aligned at both ends, the third battery exchange space 3 is connected to the first maintenance space 101 and the second maintenance room 201, and there is a placement space between the first battery exchange space 1 and the second battery exchange space 2, forming a "C"-shaped or "U"-shaped automatic battery exchange station.

[0035] In this embodiment, the battery replacement operation can be performed for at least two vehicles 8 to be replaced at the same time.

[0036] In this embodiment, there is a certain placement space between the first battery exchange space 1 and the second battery exchange space 2, and the placement space can accommodate at least one vehicle 8 to be exchanged. The size of the placement space can be adjusted by setting the distance between the first battery exchange space 1 and the second battery exchange space 2. The size of the third battery exchange space 3 is related to the size of the placement space.

[0037] Please refer to Figure 3 , is a schematic diagram of the architecture of an automatic battery swap station according to an embodiment of the present application.

[0038] In this embodiment, the first port 301 of the third battery exchange space 3 is connected to the first operation and maintenance room 101, and the second port 302 of the third battery exchange space 3 is connected to the second operation and maintenance room 201, forming the automatic battery exchange area 303.

[0039] The automatic battery swap station has symmetrical entrances and exits. In one embodiment, the entrance includes positions corresponding to the head and tail ends of the placement space. The vehicle 8 to be replaced with a battery can enter the placement space from the positions corresponding to the head and tail ends to wait for or perform battery replacement. The exit includes the lower area of ​​the third battery swap space 3. After the vehicle 8 to be replaced with a battery completes the battery swap, it can exit from the exit. In one embodiment, the head and tail ends are arranged relative to the lower area of ​​the third battery swap space, so the vehicle 8 to be replaced with a battery has a straight route from entering the automatic battery swap station to exiting the automatic battery swap station, which can save the battery replacement time of the vehicle 8 to be replaced with a battery.

[0040] In one embodiment, the height range of the inlet and outlet of the automatic battery swap station is 2855 mm to 3780 mm, and the width range is 2100 mm to 2490 mm. Other technicians in this field can adjust the appropriate height and width according to actual engineering needs.

[0041] Please refer to Figure 2 , which is a side structural diagram of an automatic battery swap station according to an embodiment of the present application.

In other embodiments, the connection mode of the support structure unit can be determined according to the scale of the battery swap station.

[0045] In one embodiment, the automatic battery exchange station has a two-layer structure, the first battery exchange space 1 or the second battery exchange space 2 is formed by stacking four supporting structure units, and the third battery exchange space 3 is built in the air by one supporting structure unit.

[0046] In one embodiment, the first battery exchange space 1 or the second battery exchange space 2 is formed by stacking four supporting structure units, and the third battery exchange space 3 is formed by suspended construction of two supporting structure units.

[0047] In other embodiments, the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3 can be constructed by any number of supporting structure units, as long as the internal space of the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3 can place the battery exchange equipment and the height of the automatic battery exchange station can pass the vehicle 8 to be replaced.

[0048] Please refer to Figure 3 , is a schematic diagram of the architecture of an automatic battery swap station according to an embodiment of the present application.

[0050] In one embodiment, the first battery exchange space 1 or the second battery exchange space 2 is formed by stacking four supporting structure units, and the third battery exchange space 3 is formed by suspended construction of two supporting structure units.

[0051] In other embodiments, the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3 can be constructed by any number of supporting structure units, as long as the internal space of the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3 can place the battery exchange equipment and the height of the automatic battery exchange station can pass the vehicle 8 to be replaced.

In one embodiment, the support structure unit is connected by thread, which can be easily disassembled and installed. In other embodiments, the connection mode of the support structure unit can be determined according to the scale of the automatic battery swap station.

[0053] The connecting beam 10 in the automatic battery exchange station is arranged at one end of the first battery exchange space 1 and the second battery exchange space 2, which can improve the stability of the automatic battery exchange station.

[0054] The support structure unit is made of a material with certain rigidity, strength, high temperature resistance and corrosion resistance, such as any one of aluminum alloy, steel, titanium alloy and galvanized steel. In one embodiment, the frame structure has a tensile strength of 310MPa, a yield strength of 276MPa, a thermal expansion coefficient of 23.6-25.0μm / m·k and an aluminum alloy plate with an operating temperature of -60℃ to 120℃. Other technicians in this field can select materials that meet the requirements according to actual engineering needs.

[0057] In this embodiment, not only the battery box 4 required for battery replacement is provided, but also a charging pile 5 is provided to charge the battery box 4. In one embodiment, the connection between the charging pile 5 and the battery box 4 is achieved by the automatic battery replacement robot or the battery replacement equipment or manually.

[0058] In an embodiment, the battery box 4 and the charging pile 5 are arranged in the space below the first battery swap station 102 or the second battery swap station 202, and the setting positions of the battery box 4 and the charging pile 5 correspond one to one, so that the battery box 4 can be connected to the charging pile 5, and the charging pile 5 can charge the battery box 4.

[0059] Below the third battery swapping space 3 is an automatic battery swapping area, which is used for battery swapping of at least one of the vehicles 8 to be swapped, and the automatic battery swapping area can pass through at least one of the vehicles 8 to be swapped. The automatic battery swapping area 303 is used for battery swapping of at least one of the vehicles 8 to be swapped, and the automatic battery swapping area 303 can pass through at least one of the vehicles 8 to be swapped.

[0060] In one embodiment, the first operation and maintenance room 101 is connected to the first battery exchange station room 102 and the third battery exchange space 3, and the second operation and maintenance room 201 is connected to the second battery exchange station room 202 and the third battery exchange space 3.

[0061] The automatic battery exchange station also includes a guide rail, which is arranged in the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3, and is located in the upper space of the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3.

[0062] The automatic battery swap station also includes at least one automatic battery swap robot, which can move along the guide rail and interact with the vehicle to be replaced 8 and the battery swap device, so as to realize the battery swap operation of the vehicle to be replaced 8. The automatic battery swap robot can clamp and install the battery box 4 of the vehicle to be replaced 8 to perform the battery swap operation.

[0063] Since the guide rail is located in the upper space of the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3, movement space is reserved for the automatic battery exchange robot. The automatic battery exchange robot can dive down or retract to interact with the battery exchange device or perform battery exchange operations.

[0064] In one embodiment, the automatic battery-changing robot includes a guide wheel mechanism, an identification and analysis module, and a clamping mechanism, wherein: the guide wheel mechanism is used to connect to the guide rail, and the automatic battery-changing robot can move along the guide rail through the guide wheel mechanism; the identification and analysis module is used to identify and analyze the battery replacement position of the vehicle 8 to be replaced, the required battery box model of the vehicle 8 to be replaced, and identify the model and position of the battery in the battery replacement device; the clamping mechanism is connected to the identification and analysis module, and is used to disassemble and install the battery box according to the identification and analysis results of the identification and analysis module.

[0065] The guide rail includes a detachable sub-guide rail for disassembly and movement. The sub-guide rail includes a first sub-guide rail 601 that matches the length and shape of the first battery swap station 102, a second sub-guide rail 602 arranged in the first operation and maintenance room 101, a third sub-guide rail 605 that matches the length and shape of the third battery swap space 3, a fourth sub-guide rail 604 arranged in the second operation and maintenance room 201, and a fifth sub-guide rail 603 that matches the length and shape of the second battery swap station 202.

[0066] In one embodiment, matching threads are respectively provided at both ends of each sub-guide rail, and one sub-guide rail can be screwed with the other sub-guide rail, thereby realizing a detachable connection between the two sub-guide rails. In fact, a detachable connection of each sub-guide rail can also be provided as required.

[0067] In one embodiment, the space is in a "C" shape or a "U" shape with both ends aligned, and the shape of the guide rail matches the shape of the placement space, and is also in a "C" shape or a "U" shape with both ends aligned, so that the automatic battery exchange robot mounted on the guide rail can move along the guide rail to any position of the first battery exchange space 1, the second battery exchange space 2 and the third battery exchange space 3.

[0068] In one embodiment, since the second sub-guide rail 602 is set in the first operation and maintenance room 101, and the fourth sub-guide rail 604 is set in the second operation and maintenance room 201, the first operation and maintenance room 101 and the second operation and maintenance room 201 are respectively connected to the two ends of the third battery exchange space 3. Therefore, in order to achieve a smoother connection, to facilitate the movement of the automatic battery exchange robot assembled on the guide rail, and to prevent the automatic battery exchange robot and the like from vibrating due to the shape of the guide rail when moving on the guide rail, causing the battery exchange equipment grasped by the automatic battery exchange robot and the like to fall or be damaged, the second sub-guide rail 602 and the fourth sub-guide rail 604 are set as arc-shaped guide rails, so that the battery exchange robot and the battery exchange equipment assembled on the guide rail can smoothly enter the third battery exchange space 3.

[0069] Assembling a track structure with a non-linear design can also make the overall spatial layout of the battery swap station more reasonable, overcoming the drawbacks of the traditional design being too narrow and long and occupying a large amount of land.

[0070] In this embodiment, the center angle of the arc guide rail is less than or equal to 90°. In one embodiment, the center angle of the arc guide rail ranges from 60° to 90°. In fact, the center angle of the arc guide rail can be set according to actual needs.

[0071] In this embodiment, the first sub-guide rail 601 and the fifth sub-guide rail 603 are both linear guide rails to adapt to the size of the vehicle to be replaced.

[0072] In fact, the shape of the guide rail can also be set as needed. The battery replacement equipment is distributed along the guide rail, which facilitates the automatic battery replacement robot or the battery replacement equipment installed on the guide rail to grab the battery box during movement, thereby improving the battery replacement efficiency.

[0073] In another embodiment, the first sub-rail 601, the second sub-rail 602, the fourth sub-rail 604, and the fifth sub-rail 603 are all straight rails. The straight rails are laid along the length direction of the first battery exchange space 1 or the second battery exchange space 2, the battery boxes 4 are distributed along the length direction of the straight rails, and the battery boxes 4 correspond to the charging piles 5 one by one.

[0074] In one embodiment, the first sub-guide rail 601, the second sub-guide rail 602, the fifth sub-guide rail 603, the fourth sub-guide rail 604 and the third sub-guide rail 605 are made of metal materials with certain hardness, corrosion resistance and high and low temperature resistance.

[0075] In one embodiment, the material for preparing the sub-guide rail has a hardness range of 255 to 207HB, a thermal expansion coefficient range of 23.6 to 25.0, and an operating temperature range of -60°C to 120°C, and may be CrWMn material, etc. In one embodiment, the second sub-guide rail 602 and the fourth sub-guide rail 604 have a central angle of 60° to 90°, so the bendability of the material for preparing the sub-guide rail also needs to be considered. Other technicians in this field can select suitable materials and bendable angles according to actual engineering requirements, as long as they can support 2 to 3 times the weight of the automatic battery replacement robot and the battery box at the same time.

[0076] In one embodiment, the first sub-rail 601, the second sub-rail 602, the fifth sub-rail 603, the fourth sub-rail 604 and the third sub-rail 605 are connected in sequence to form a "C"-shaped rail; in one embodiment, the first sub-rail 601, the second sub-rail 602, the fifth sub-rail 603, the fourth sub-rail 604 and the third sub-rail 605 are connected in sequence to form a "Z"-shaped rail. In other embodiments, the length of the rail can be adjusted according to actual engineering requirements, as long as the curvature and material requirements of the rail can meet the actual engineering requirements.

[0077] In one embodiment, the guide rail is a single-track guide rail. In this case, the guide wheel mechanism is a single-wheel mechanism, and the single-wheel mechanism is arranged on the guide rail. The guide wheel mechanism is more flexible and can perform turning operation. Compared with the solution using a double-track guide rail and a double-wheel mechanism, the single-track guide rail and single-wheel mechanism in this embodiment can even make the movement path of the automatic battery swapping robot circular, so that the battery swapping equipment package can be evenly distributed on both sides of the automatic battery swapping station, overcoming the shortcomings of the automatic battery swapping robot being unable to turn due to the use of a double-track guide rail and the overall design of the track of the battery swapping station being too long.

[0078] The identification and analysis module is arranged on the automatic battery-changing robot to determine the position and model of the battery to be replaced; the clamping mechanism adjusts the opening width of the clamp according to the structure of the identification and analysis module.

[0079] Structurally, unlike the traditional double-track battery-changing trolley, this design uses a single-track lifting trolley to achieve a circular track that the double-track lifting trolley in the traditional design cannot achieve.

[0080] In one embodiment, the automatic battery-changing robot includes: the automatic battery-changing robot 10 and the automatic battery-changing robot 9.

[0081] The automatic battery-changing robot can work in a "two-person mode", that is, the automatic battery-changing robot 10 and the automatic battery-changing robot 9 work together, including two sub-working modes: the automatic battery-changing robot 10 draws power and the automatic battery-changing robot 9 loads power and the automatic battery-changing robot 9 draws power and the automatic battery-changing robot 10 loads power.

[0082] In another embodiment, the battery-swapping robot can work in a "single-person mode", that is, the automatic battery-swapping robot 10 and the automatic battery-swapping robot 9 work separately, including: the automatic battery-swapping robot 10 completes the work of taking and installing electricity, and the automatic battery-swapping robot 9 performs maintenance and the automatic battery-swapping robot 9 completes the work of taking and installing electricity, and the automatic battery-swapping robot 10 performs maintenance. Other technicians in this field can set an appropriate amount of the automatic battery-swapping robots according to actual engineering needs, as long as the automatic battery-swapping robots can improve the battery-swapping efficiency of the automatic battery-swapping station.

[0083] In this embodiment, two automatic battery-changing robots are designed, and these two automatic battery-changing robots can work independently or cooperate with each other to complete the entire automatic battery-changing process. When independently changing batteries, they can serve two heavy trucks at the same time; when working in cooperation with each other, one lifting automatic battery-changing robot takes the old battery pack connected to the heavy truck, and the other lifting automatic battery-changing robot takes the fully charged new battery pack. The two devices work together to shorten the replacement time to 1 / 2 of the traditional solution.

[0084] In one embodiment, the battery replacement steps of the automatic battery replacement robot include: Step 1: The automatic battery replacement robot opens the battery box lock of the vehicle to be replaced 8; Step 2: The automatic battery replacement robot 9 or the automatic battery replacement robot 10 clamps and takes out the battery box to be replaced of the vehicle to be replaced 8, and transports it to the charging area; Step 3: The automatic battery replacement robot 9 or the automatic battery replacement robot 10 clamps the fully charged battery box and runs to the battery replacement area, and places the fully charged battery box in the original battery box area of ​​the vehicle to be replaced 8; Step 4: The automatic battery replacement robot 9 or the automatic battery replacement robot 10 closes the battery box lock of the vehicle to be replaced 8 to complete the battery replacement operation.

[0085] In one embodiment, the battery replacement steps of the automatic battery replacement robot include: Step 1: The automatic battery replacement robot 9 runs to the top of the battery box to be replaced and opens the battery box lock of the vehicle to be replaced 8, and at the same time, the automatic battery replacement robot 10 grabs the fully charged battery box 4 and waits in the automatic battery replacement area 303; Step 2: The automatic battery replacement robot 9 clamps and takes out the battery box to be replaced of the vehicle to be replaced 8, and transports it to the charging area. The automatic battery replacement robot places the clamped fully charged battery box 4 into the original battery box position of the vehicle to be replaced 8, and closes the battery box lock of the vehicle to be replaced 8 to complete the battery replacement operation.

[0086] In one embodiment, the automatic battery exchange station also includes a membrane structure, a first gate is provided at the port of the first battery exchange space 1, and a second gate is provided at the port of the second battery exchange space 2; when the gates are closed, the membrane structure and the first gate surround the first battery exchange space 1, and the membrane structure and the second gate surround the second battery exchange space 2.

[0087] After the membrane structure and the first gate enclose the first battery exchange space 1, dust can be reduced from entering the first battery exchange space 1. After the membrane structure and the second gate enclose the second battery exchange space 2, dust can be reduced from entering the second battery exchange space 2. In this way, the service life of the battery exchange devices placed in the first battery exchange space 1 and the second battery exchange space 2 is longer.

[0088] The automatic battery swap station further includes a connecting beam 10 and a gate 7. The connecting beam 10 is a rigid structure, suspended to connect the head and tail ends of the space, and the gate 7 is arranged below the connecting beam 10. In one embodiment, the head end of the placement space corresponds to the first battery swap station room 102, and the tail end of the placement space corresponds to the second battery swap station room 202.

[0089] The connecting beam 10 and the gate 7 can be used as the entrance and exit of the automatic battery swap station. The gate 7 has the characteristics of thermal insulation, high strength and strong resistance to wind and dust. In one embodiment, the gate 7 is made of a double-layer high-quality color steel plate with a thickness ranging from 0.5mm to 1mm, and there is a filling material between the double-layer high-quality color steel plates, and the filling material includes any one of polyurethane foam material, phenolic resin foam material and foamed polystyrene material. Other technicians in this field can select filling materials suitable for the environment and application according to actual engineering needs.

[0090] In one embodiment, all the battery swapping spaces of the automatic battery swapping station are modularly arranged and can be divided as needed for transportation. When in use, they only need to be assembled into a unified whole on site.

[0091] In one embodiment, the automatic battery swap station can be organically divided into 9 parts, including 8 main structure modules composed of the support frame, and 1 battery swap module composed of the automatic battery swap robot and guide rails, etc. In some embodiments, the size of the main structure module is similar to that of a standard container, and the structural size of a battery swap module is equivalent to 1 / 3 of the container size.

[0092] The modular structure makes it very convenient to disassemble and assemble the battery swap station. After serving an area, the battery swap station can be immediately disassembled into 9 modules, and ordinary vehicles can be used to transport and transfer the station to continue serving the next area. At the same time, most of the installation and commissioning work of the modular design is completed in the factory, which greatly reduces the on-site construction of the factory and the on-site installation and commissioning time of the equipment, saving construction costs. At the construction site, only 9 modules need to be stacked and connected. After forming a whole, the equipment can be operated. There are basically no requirements for local civil engineering / housing construction.

[0093] Different from traditional civil construction schemes, the integrated modular battery swap station designed in this invention does not require on-site construction of houses, foundation / pile making and other civil construction operations; the combination of equipment can rely only on the interface connection between steel structures and rely on its own weight to achieve the stability of the overall structure. No on-site construction is required, and no expensive foundation manufacturing costs are required.

[0094] The above descriptions are merely embodiments of the present application and are not intended to limit the patent scope of the present application. Any equivalent structural or equivalent process transformations made using the contents of the specification and drawings of the present application, such as the mutual combination of technical features between the embodiments, or direct or indirect application in other related technical fields, are also included in the patent protection scope of the present application.
