Description

Technical Field

[0001] This application belongs to the technical field of battery swapping stations, and particularly relates to the technical field of charging bins. Background Art

[0002] In response to the global call for energy conservation and emission reduction, in recent years, mechanical equipment powered by fuel has gradually been replaced by electric mechanical equipment. However, problems such as short battery life, slow charging, and rapid battery decay in electric mechanical equipment also restrict the application of electric machinery. To solve this problem, battery swapping stations that directly swap batteries for electric devices are provided on the market. Multiple fully charged battery boxes are stored in the battery swapping station. A vehicle with a discharged battery can drive to the battery swapping station, unload the discharged battery box into the charging bin of the battery swapping station, and load a fully charged battery box in the battery swapping station into the vehicle.

[0003] Existing heavy truck battery swapping stations mainly use overhead rail swapping stations. The whole station adopts a structural form of overhead rail, gantry robot, winch lifting, double-row battery bin layout, and upper and lower sub-boxes in the station building. The existing battery swapping stations have the following defects:

[0004] 1) The battery swapping time of the battery swapping station is long and the battery swapping efficiency is low;

[0005] 2) The degree of freedom of the battery swapping mechanism is insufficient. There is no rotational degree of freedom in the R direction, and the tolerance distances in the X and Y directions are small. The success rate of a single battery swap of the battery swapping structure is low;

[0006] 3) The accuracy requirement for the vehicle parking position is extremely high. The driver needs to move the vehicle repeatedly, and the driver's battery swapping experience is poor;

[0007] 4) The heat dissipation of the station building is poor, and high temperatures in summer will trigger shutdown;

[0008] 5) In high-load scenarios, the steel wire ropes of the lifting mechanism (winch) frequently come out of the groove, get tangled, and break, requiring frequent maintenance;

[0009] 6) The overhead rail is installed on the upper box of the station building. After the battery swapping robot runs for a long time, the deformation of the station building increases. The box transformer of the station building will cause water leakage, and at the same time, it will cause the parallelism of the overhead rail to become larger, and the robot is prone to jamming;

[0010] 7) The battery swapping robot is installed on the overhead rail, which is not convenient for maintenance;

[0011] 8) Lack of a fire-fighting maintenance workbench;

[0012] 9) The station building is too wide, which is not convenient for transportation. It needs to be reported in advance before it can be driven on the road, and the transportation cost is high. Summary of the Invention

[0127] This embodiment provides a heavy truck battery swapping station for shortening the battery swapping time and improving the battery swapping efficiency.

[0128] The following will combine Figures 1 to 24 to elaborate in detail the principle and implementation manner of a charging structure of the heavy truck battery swapping station in this embodiment, so that those skilled in the art can understand the charging structure of the heavy truck battery swapping station in this embodiment without creative labor.

[0129] As Figure 1 shown, this embodiment provides a heavy truck battery swapping station, including: a battery swapping station building 1 and a battery swapping channel 2; an arc-shaped charging bin 11, a linear charging bin 12, and a battery swapping robot 13 are provided in the battery swapping station building 1.

[0130] Among them, in this embodiment, as Figure 2As shown, the arc-shaped charging bin 11 is composed of a plurality of battery bins 10 arranged in an arc shape. Preferably, the plurality of battery bins 10 are arranged in a 1 / 4 circular arc shape. The linear charging bin 12 is composed of a plurality of battery bins 10 arranged in a linear shape. In this embodiment, the battery bins 10 in the heavy truck battery swapping station adopt a combined layout structure of arc shape and linear shape, with short battery swapping time and high battery swapping efficiency.

[0131] The following will detail the arc-shaped charging bin 11 and the linear charging bin 12 of this embodiment.

[0132] In a possible implementation manner, each of the battery bins 10 in the arc-shaped charging bin 11 and the linear charging bin 12 is directly placed or fixed in the battery swapping station building 1. In this embodiment, as Figures 3 to 11 shown, the battery bin 10 includes: a mounting rack, a bottom tray, and a charger. The bottom tray is used to install the battery box, is installed on the mounting rack, and determines the installation position on the mounting rack according to the application state scenario. The bottom tray is provided with a connector for the battery box; the charger is connected to the connector of the battery box through a wire harness.

[0133] In this embodiment, the bottom tray 120 mainly stores the battery box, for example, is connected to the mounting rack 110 by bolts.

[0134] In another possible implementation manner, the arc-shaped charging bin 11 and the linear charging bin 12 are respectively a modular charging bin. The arc-shaped charging bin 11 and the linear charging bin 12 respectively include: a charging rack. As Figures 3 to 11 shown, in this embodiment, the mounting racks of each of the battery bins 10 are arranged on the top of the charging rack; a protective plate is installed on the surrounding sides of the charging rack, so that a closed space is formed inside the charging rack; at least one louver is installed on the side of the charging rack and close to the charger for dissipating heat from the charger; an air inlet, an air outlet, a fan, and an air duct. The air inlet and the air outlet are respectively arranged at both ends of the charging rack. The fan is fixed inside the charging rack, and the air duct is formed in the closed space formed inside the charging rack to discharge the heat of the charger.

[0135] In this embodiment, the bottom tray 120 mainly stores the battery box, for example, is connected to the mounting rack 110 by bolts.

[0136] In one embodiment, as Figures 3 to 5 shown, the mounting rack 110 is inclined at a preset angle relative to the edge of the charging rack 100.

[0137] In a possible implementation manner, in a non-working state scenario, as Figures 3 to 5As shown, the installation positions of the multiple base trays 120 on each mounting frame 110 are such that the edges of each base tray 120 are all within the charging rack 100. For example, during transportation, the base tray 120 is adjusted to within the width range of the charging bin to ensure that the transportation does not exceed the width limit. During operation, the base tray 120 is adjusted to the shown working state.

[0138] Among them, when the battery compartment 10 is placed in the arc-shaped charging bin 11, a circular arrangement is formed among the multiple base trays, and the center lines of each base tray intersect at a point, such that the multiple battery compartments 10 are arranged in an arc shape; when the battery compartment 10 is placed in the linear charging bin 12, a linear arrangement is formed among the multiple base trays, such that the multiple battery compartments 10 are arranged in a linear shape.

[0139] In a possible implementation manner, when the battery compartment 10 is placed in the arc-shaped charging bin 11, as Figures 8 to 11 shown, in the working state scenario, a circular arrangement is formed among the multiple base trays 120, and the center lines of each base tray 120 intersect at a point. That is, a circular arrangement is formed among the base trays 120, and the center lines of each base tray 120 intersect at a point (the rotation center of the battery box transfer device). The battery box transfer device can achieve the transfer function of the battery box only through rotational movement at this point.

[0140] In another embodiment, the mounting frame 110 is parallel to the edge of the charging rack 100. Figures 8 to 11 It shows another assembly structure schematic diagram of the mounting frame 110 and the charging rack 100 of the heavy truck battery swapping station of the present application.

[0141] In a possible implementation manner, when the battery compartment 10 is placed in the linear charging bin 12, in the working state scenario, a linear arrangement is formed among the multiple base trays 120. Each base tray 120 is arranged linearly, and the battery box transfer device transports the battery box to different positions on the line through linear movement to achieve the conversion of different positions of the battery box.

[0142] In this embodiment, the charger 150 (including the connector) mainly provides electrical energy for the battery box and is fixed to the charging rack 100 by, but not limited to, bolts. For the sake of heat dissipation, the charger 150 is preferably arranged in the area of the charging rack 100 close to the outside. In a possible implementation manner, the charger 150 is fixed to the rear end inside the charging rack 100.

[0143] In this embodiment, the protective plate 130 is installed on the surrounding sides of the charging rack 100, such that a sealed space is formed inside the charging rack 100. Each protective plate 130 mainly functions to seal and insulate, and is installed on the side of the charging bin, such that a sealed space is formed inside the charging rack 100.

[0144] In this embodiment, it includes at least one louver 140, and each louver 140 is installed on the side of the charging rack 100 and close to the charger 150 for dissipating heat from the charger 150. Figure 12 It shows a structural example diagram of the louver 140 of the heavy truck battery swapping station of the present application. In this embodiment, the louver 140 is mainly for facilitating heat dissipation of the charger 150 and is installed on the side of the charging bin, close to the charger 150.

[0145] Specifically, in this embodiment, as Figure 13 shown, a rain shield 141, a dust filter 142 and a sound-absorbing cotton 143 are provided on the louver 140; locking tongues 144 are provided around the louver for assembling and connecting with the charging rack 100. Among them, the rain shield 141 is installed around the window of the louver 140, the dust filter 142 faces the window of the louver 140 and is installed inside the rain shield 141, and the sound-absorbing cotton 143 is installed around the dust filter 142. The louver 140 is fixed on the charging rack 100 through the locking tongues 144. As Figure 15 and Figure 16 shown, the charger 150 is fitted and assembled with the louver 140, and the rear end of the charger 150 is directly opposite to the window of the louver 140. Among them, the rain shield 141 in the louver 140 can not only play a rain-proof role, but also form an air duct between the charger 150 and the louver 140, so that the heat discharged from the charger 150 is directly discharged to the outside of the charging bin through the louver 140.

[0146] In this embodiment, the air inlet and the air outlet are respectively arranged at both ends of the charging rack 100, and the fan 160 is fixed inside the charging rack 100 to form an air duct in the sealed space formed in the inner cavity of the charging rack 100 to discharge the heat of the charger 150. Figure 17 It shows a structural example diagram of the fan 160 of the heavy truck battery swapping station of the present application. The fan 160 mainly discharges the heat in the charging bin to the outside of the charging bin to ensure that the charger 150 works at a rated temperature. The fan 160 is fixed on the charging rack 100 by, but not limited to, bolts.

[0147] That is, in this embodiment, the charger is built inside the charging rack. The charger inhales cold air through the air duct, the air outlet of the charger is closely attached to the sound-absorbing cotton on the louver of the charger, and the hot air discharged from the charger is discharged out of the station house through the louver.

[0148] In a possible implementation manner, the fan 160 can be configured as a blower 160 or an exhaust fan 160.

[0149] As Figure 18 and Figure 20As shown, in a possible implementation, the arc-shaped charging bin 11 and the linear charging bin 12 are spliced and combined; in the working state scenario, a circular arrangement is formed among multiple bottom trays 120 in the arc-shaped charging bin 11, and the center lines of each bottom tray 120 intersect at a point, and a linear arrangement is formed among multiple bottom trays 120 in the linear charging bin 12.

[0150] That is, in this embodiment, both the arc-shaped charging bin 11 and the linear charging bin 12 include a charging rack 100, and a bottom tray 120 of the battery box, a charger 150 (including a connector), a drum (exhaust) fan 160 (hereinafter referred to as the fan 160), a louver 140, a protective cover, etc. are installed on the charging rack 100, forming an independent charging module. The arc-shaped charging bin 11 and the linear charging bin 12 form a ring-shaped + linear battery box arrangement, achieving the optimal solution that can not only shorten the battery replacement time but also be expandable.

[0151] The arc-shaped charging bin 11 and the linear charging bin 12 are spliced and combined together through a connecting beam 180. Figure 19 It shows a schematic diagram of the connecting beam 180 in an embodiment of the charging structure of the present application.

[0152] In a possible implementation, after the arc-shaped charging bin 11 and the linear charging bin 12 are spliced and combined, the inner cavities of the two charging racks 100 form a sealed space, wherein the fan 160 in the arc-shaped charging bin 11 is set as a blower 161, and the fan 160 in the linear charging bin 12 is set as an exhaust fan 162.

[0153] In a possible implementation, in the arc-shaped charging bin 11, multiple battery bins 10 are arranged in an arc shape of more than one layer; in the linear charging bin 12, multiple battery bins 10 are arranged in a linear shape of more than one column.

[0154] When the number of battery bins 10 in the battery swapping station needs to be expanded, the number of rows of the battery bins 10 can be increased, and the width of the battery swapping station building 1 can be increased. Specifically, in this embodiment, the placement position of the battery bins 10 can be expanded through different combinations. In the layout structure combined with the arc-shaped charging bin 11 and the linear charging bin 12, layouts such as arc-shaped + linear + arc-shaped and arc-shaped + linear + linear are also formed, which is convenient for the subsequent expansion of the battery swapping station, and the expandability of the number of battery bins 10 is strong.

[0155] As can be seen from the above, in this embodiment, the charging bin structure is composed of an arc-shaped charging bin 11, a linear charging bin 12, a connecting beam 180 and mounting bolts, and the overall structure is an "L" shape. The arc-shaped charging bin 11 and the linear charging bin 12 are connected by the connecting beam 180 and mounting bolts.

[0156] The bottom trays 120 of the arc-shaped charging bin 11 are arranged in a ring shape, and the center lines of the bottom trays 120 intersect at a point. The battery box transfer device (such as the battery swapping robot 13) can achieve the conversion of the battery box between different bins through rotational motion at this point. The bottom trays 120 of the linear charging bin 12 are arranged in a linear shape, and the battery box transfer device transports the battery box to different bins on the line through linear motion to achieve the conversion of the battery box between different bins. Therefore, in this embodiment, the bottom trays 120 of the arc-shaped charging bin 11 and the linear charging bin 12 in the charging bin structure adopt a ring-shaped + linear arrangement, which can not only shorten the battery swapping time but also has scalability to meet the subsequent expansion requirements of the battery swapping station.

[0157] After the arc-shaped charging bin 11 and the linear charging bin 12 are combined, a sealed space is formed inside the charging bin cavity (the arc-shaped charging bin 11 and the linear charging bin 12 can also be used as a sealed body by installing a protective plate 130); one of the two fans 160 can be set as a blower 160, and the other is set as an exhaust fan 160. The fan 160 forms an air duct with the sealed space inside the charging bin cavity, which can take out the heat dissipated during the operation of the charger 150, ensure that the charger 150 operates at the rated working temperature, effectively guarantee the operation reliability of the charger 150, and ensure the charging efficiency.

[0158] Therefore, in this application, the battery bin 10 is arranged on the charging rack, the charging rack is enclosed by a protective plate (skin), and an inner cavity forms a cavity, which is used as a heat dissipation air duct. Air inlets and outlets (with filters) are arranged at both ends of the charging rack, and fans are used for blowing and exhausting; the inner edge of the louver (with filter) window is pasted with sound-absorbing cotton on the outside of the charging rack; both the air inlets and outlets of the closed air duct and the louver window have filters, with good dust-proof effect, ensuring the cleanliness of the environment where the charger is used.

[0159] The arc-shaped charging bin 11 and the linear charging bin 12 can expand the placement positions of the battery boxes through different combinations. Combining two types of charging bins, namely the heavy truck battery swapping station with a ring-shaped layout and the heavy truck battery swapping station with a linear layout, can also form layout schemes such as ring-shaped + linear-shaped + ring-shaped, ring-shaped + linear-shaped + linear-shaped, etc., which is convenient for the subsequent expansion of the battery swapping station.

[0160] In this embodiment, the arc-shaped charging bin 11 and the linear charging bin 12 in the battery swapping station building 1 can adopt modular design respectively, and the modules are not over-wide, and they are transported to the site for rapid assembly.

[0161] In a possible implementation manner, a first switch door 15 is opened on the wall of the battery swapping station building 1 (near the door 17) that is in contact with the heavy rail of the battery swapping robot 13, and the heavy truck battery swapping station further includes a fire protection and maintenance warehouse 14 arranged outside the first switch door 15.

[0162] The fire-fighting maintenance warehouse 14 is located outside the battery swapping station building 1. When the battery in the battery swapping station building 1 undergoes thermal runaway, the battery swapping robot 13 can automatically grab the thermally runaway battery and quickly move it to the fire-fighting maintenance warehouse 14 outside the battery swapping station building 1, with little safety hazard.

[0163] As can be seen from the above, in this embodiment, the battery warehouse 10 adopts a layout of 1 / 4 arc + 1 row + 1 fire-fighting maintenance warehouse 14. The fire-fighting maintenance warehouse 14 is arranged outside the battery swapping station building 1. The layout of the arc-shaped battery positions shortens the X-direction travel of the battery swapping robot 13, reduces the battery swapping time, and improves the battery swapping efficiency. When the battery undergoes thermal runaway or needs maintenance, the battery swapping robot 13 can transfer the battery to the fire-fighting maintenance warehouse 14 outside the station building for operation.

[0164] In this embodiment, an entrance and an exit are respectively provided at the front end and the rear end of the battery swapping channel 2. A second switch door 19 is opened on the wall of the battery swapping station close to the battery swapping channel 2, and the battery swapping station building 1 and the battery swapping channel 2 are connected through the second switch door 19 (sliding door).

[0165] When the depleted battery 31 of the battery swapping vehicle 3 needs to be replaced, the battery swapping vehicle 3 stops at the battery swapping area of the battery swapping channel 2. The second switch door 19 (sliding door) is opened, and the battery swapping robot 13 removes the battery from the battery swapping vehicle 3 and transfers it to the battery warehouse 10 for charging. Specifically as follows:

[0166] In this embodiment, a monitoring room 18 (close to the door 17) is provided in the battery swapping station building 1. When the battery swapping vehicle 3 enters the entrance of the battery swapping channel 2, the license plate is recognized through the vehicle vision recognition system for vehicle authentication. After the battery swapping vehicle 3 enters the battery swapping channel 2, the sliding door is opened. The cantilever and spreader of the battery swapping robot 13 extend to remove the depleted battery 31 of the vehicle and transfer it to the empty battery warehouse 10 in the battery swapping station. The battery swapping robot 13 grabs a fully charged battery from the battery warehouse 10 and installs it on the battery swapping vehicle 3. After the battery swapping is completed, the robot cantilever and spreader retract into the station building, the sliding door is closed, and the dustproof effect is good. The battery swapping robot 13 transfers the depleted battery 31 on the empty warehouse to the charging position for charging. The battery swapping vehicle 3 drives away from the battery swapping channel 2 from the exit.

[0167] A canopy is provided above the battery swapping area of the battery swapping channel 2 to prevent rain and snow from falling on the vehicle battery connector. Guardrails or steel-cast deceleration strips 21 are provided on both sides of the battery swapping channel 2 to guide the vehicle. A steel-cast deceleration strip 21 is provided in the battery swapping area of the battery swapping channel 2 to position the wheels, realizing rough positioning of the battery swapping vehicle 3. In this embodiment, a lidar 22 is also provided at the battery swapping channel 2 for positioning the battery swapping vehicle 3, and a point laser is used for precise battery positioning with high positioning accuracy. According to the positioning information, the battery swapping robot 13 actively adjusts the battery swapping posture. In addition, the battery swapping channel 2 is also equipped with a display screen, a voice broadcaster, traffic lights, etc. to guide the battery swapping vehicle 3.

[0168] When the power-depleted battery 31 needs battery replacement maintenance or thermal runaway occurs, the rolling shutter door opens, and the battery replacement robot 13 grabs the battery and transfers it to the fire repair warehouse 14 for repair and maintenance. The thermally runaway battery is separated from the battery replacement station building 1, ensuring safety and reliability.

[0169] In this embodiment, the battery replacement robot 13 is used to interchange the battery in the battery compartment 10 with the battery of the battery replacement vehicle 3 parked in the battery replacement channel 2. The battery replacement robot 13 is configured with an electric control box 131, and buffer bumpers are provided in the battery replacement station building. As Figure 21 shown, the battery replacement robot 13 includes: a heavy rail 220, an RGV car 220, a slewing bearing 230, a rotating platform 240, a translation table 250, a gantry lifting mechanism 260, a cantilever 270, and a lifting tool 280.

[0170] As Figures 22 to 24 shown, the RGV car 220 is arranged on the heavy rail 220 and moves along the heavy rail 220 through a car driving mechanism; the slewing bearing 230 is arranged between the RGV car 220 and the rotating platform 240, and the rotating platform 240 is rotated through a slewing driving mechanism; a platform guide rail 245 is arranged on the rotating platform 240, and the translation table 250 moves along the platform guide rail 245 through a translation slider 242 and a platform driving mechanism; the gantry lifting mechanism 260 is arranged on the translation table 250, and the gantry lifting mechanism 260 includes an I-beam column 262, lifting guide rails 262 arranged on both sides of the I-beam column 262, a lifting platform 264 connected to the lifting guide rails 262 through a lifting slider 263, and a lifting driving mechanism for driving the lifting platform 264 to move along the lifting guide rails 262; a cantilever 270, with the first end fixed to the lifting platform 264 of the gantry lifting mechanism 260 and the second end fixed to the lifting tool 280; the lifting tool 280 includes a battery hook locking mechanism for connecting with the battery.

[0171] The following specifically describes the heavy rail 220, RGV car 220, slewing bearing 230, rotating platform 240, translation table 250, gantry lifting mechanism 260, cantilever 270, and lifting tool 280 of this embodiment.

[0172] In a possible implementation manner, anti-collision columns 222 are provided at both ends of the heavy rail 220. The anti-collision columns 222 are, for example, polyurethane buffer anti-collision columns.

[0173] The wheels 222 of the RGV cart 220 are placed on the heavy rail 220 and move along the heavy rail 220 through the cart drive mechanism. The span of the walking cart is large. In various battery swapping postures of the battery swapping robot 13, the center of gravity falls within the area of the four wheels 222 and is far from the edges of the wheels 222, making the movement of the battery swapping robot 13 more stable.

[0174] In a possible implementation manner, the RGV cart 220 adopts eccentric bolt rollers, and a laser guiding mechanism is provided on the RGV cart 220. Among them, the use of eccentric bolt rollers can perform limit correction of the wheels 222, and the laser guiding mechanism is used to realize the laser guiding of the RGV cart 220 in the X direction.

[0175] In a possible implementation manner, a grease pump 223 and a corresponding distribution valve 224 (such as a progressive distribution valve) are installed on the RGV cart 220. The cart drive mechanism includes a cart servo motor 225 and a planetary reducer; the cart servo motor 225 is connected to the drive shaft 226 and the wheels 222 of the RGV cart 220 through the planetary reducer. The drive shaft 226 is in two roots and is connected by a cart coupling 222. One cart servo motor 225 drives two drive shafts 226, which can ensure the synchronism of the movement of the wheels 222.

[0176] In addition, a drag chain 202 can be provided on the RGV cart 220, and a drag chain groove 203 is provided on the ground. The drag chain 202 is arranged in the drag chain groove 203, and the RGV cart 220 is dragged through the drag chain 202 on the RGV cart 220.

[0177] In this embodiment, the slewing bearing 230 is arranged between the RGV cart 220 and the rotating platform 240, and the rotation of the rotating platform 240 is realized through the slewing drive mechanism.

[0178] In a possible implementation manner, as Figure 22 shown, the slewing bearing 230 is a helical slewing bearing. The slewing drive mechanism includes a slewing servo motor, a reducer, and a slewing gear 232 (helical); the reducer is connected between the slewing servo motor and the slewing gear 232. The slewing gear 232 meshes with the helical slewing bearing 230 to drive the slewing bearing 230 to rotate, and the slewing bearing 230 drives the rotating platform 240 to rotate.

[0179] That is, a helical slewing bearing is installed on the RGV cart 220. The slewing bearing 230 is connected to the bottom of the rotating platform 240. The slewing servo motor is connected to the slewing gear 232 (helical) through the reducer. The high-precision R-direction rotation of the rotating platform 240 is realized through the meshing of the slewing gear 232 (helical) and the slewing bearing 230.

[0180] In this embodiment, as Figure 24 shown, a platform guide rail 245 is provided on the rotating platform 240. Collision columns 246 are provided at both ends of the platform guide rail 245. The translation stage 250 moves along the platform guide rail 245 through translation sliders 242 and a platform driving mechanism.

[0181] In a possible implementation manner, the platform driving mechanism includes a gear 242, a rack 243, a platform servo motor 244, and a platform speed reducer. Among them, the platform servo motor 244 drives the gear 242 to rotate through the platform speed reducer. The gear 242 meshes with the rack 243, and the rack 243 drives the translation slider 242 to move along the platform guide rail 245 on the rotating platform 240.

[0182] That is, a linear platform guide rail 245, a rack 243 (helical gear), and collision columns 246 are provided on the rotating platform 240. A linear slider, a servo motor, a speed reducer, and a gear 242 (helical gear) are installed at the bottom of the translation stage 250. The rotating platform 240 and the translation stage 250 are connected together through the sleeving of the guide rail and the slider. The motor drives the gear 242 to mesh with the rack 243 to realize the Y-direction movement of the translation stage 250.

[0183] The slewing bearing 230, the driving gear 242, the gear 242 of the translation stage 250, and the rack 243 of the rotating platform 240 all adopt helical gear meshing, so that the movement accuracy of the battery swapping robot 13 is higher and the movement is smoother.

[0184] In this embodiment, as Figure 23 shown, the gantry lifting mechanism 260 is provided on the translation stage 250. The gantry lifting mechanism 260 includes an I-beam column 262, lifting guide rails 262 provided on both sides of the I-beam column 262, a lifting table 264 connected to the lifting guide rails 262 through lifting sliders 263, and a lifting driving mechanism for driving the lifting table 264 to move along the lifting guide rails 262.

[0185] In this embodiment, the end of the rotating platform 240 is counterweighted. When the robot grabs the battery, it can well balance the tipping moment and prevent the battery swapping robot 13 from tipping over, making the overall equipment more stable and reliable.

[0186] In a possible implementation manner, the lifting driving mechanism includes a lead screw transmission pair 267, an upper fixed seat 267a and a lower fixed seat 267b fixed at both ends of the lead screw transmission pair 267, and a lead screw motor 266 for driving the lead screw transmission pair 267. The lifting table 264 is sleeved on the lead screw of the lead screw transmission pair 267. The lead screw motor 266 drives the lead screw to realize the movement of the lifting table 264 along the lifting guide rails 262.

[0187] That is, in this embodiment, the gantry lifting mechanism 260 is fixed on the translation stage 250 by bolts; the gantry lifting mechanism 260 is composed of I-beam columns 262, linear guides (lifting guides 262), linear sliders (lifting sliders 263), lead screw transmission pairs 267, motor fixing seats 266a, lower fixing seats 267b, lifting platforms 264, upper fixing seats 267a, motors, bearings 265, couplings 269, etc.; the I-beam columns 262 are connected to the motor fixing seats 266a, lower fixing seats 267b, and upper fixing seats 267a by bolts, and both ends of the lead screw transmission pair 267 are respectively fixed to the lower fixing seat 267b and the upper fixing seat 267a through bearings 265. Among them, buffer pads 268a and buffer pads 268b can be provided between the lead screw transmission pair 267 and the lower fixing seat 267b and the upper fixing seat 267a. The lifting platform 264 is connected to the lifting guide 262 on the column through the lifting slider 263. The lifting platform 264 is sleeved with the lead screw, and the motor drives the lead screw to realize the Z-direction movement of the lifting platform 264.

[0188] Among them, the gantry structure of the I-beam column 262 can withstand large eccentric loads, the deformation of the gantry is small, and it has no influence on the movement of the lead screw transmission pair 267, linear guide, and slider in the gantry lifting system. The movement is smooth, without jamming, and has high movement accuracy, which improves the service life of the moving parts. Moreover, the battery swapping robot 13 uses a lead screw transmission pair 267 and guide rail sliders to lift and lower instead of a traditional winch, with low failure rate, high precision, simple and convenient maintenance, and no faults such as broken wire strands, tangled ropes, and running ropes of the steel wire ropes.

[0189] In this embodiment, the first end of the cantilever 270 is fixed to the lifting platform 264 of the gantry lifting mechanism 260, and the second end is fixed to the spreader 280. Among them, the cantilever 270 is spliced into a double-row steel box girder structure using high-strength steel, with good structural mechanical properties and small deflection.

[0190] In a possible implementation manner, as Figure 22 shown, two openings are provided at the second end of the cantilever 270. Graphite copper sleeves are installed in each opening, and cantilever electric cylinders 272 are respectively provided. Each cantilever electric cylinder 272 is respectively connected to and drives a locking column 272 to expand and contract in the opening; the locking column 272 is connected to the spreader 280, and the lower end of the locking column 272 has two-stage tapers for tolerance.

[0191] That is to say, one end of the cantilever 270 is fixed on the lifting platform 264 of the gantry lifting mechanism 260 and moves in the Z direction together with the lifting platform 264; the other end of the cantilever 270 is drilled and a graphite copper bushing is installed. The cantilever electric cylinder 272 is installed above the hole position through a fixed seat. The cantilever electric cylinder 272 drives the locking column 272 to stretch up and down inside the graphite copper bushing. The lower end of the locking column 272 has two-stage tapers for tolerance. The cantilever electric cylinder 272 drives the locking column 272 to stretch to lock and unlock the spreader 280. The locking column 272 with two-stage tapers has good tolerance. The battery swapping robot 13 can perform compound movement in X / Y / Z / R directions and can also perform the locking action of the spreader 280 simultaneously. The battery swapping beat is a compound movement, the battery swapping time is short, and the battery swapping efficiency is high.

[0192] In a possible implementation manner, the spreader 280 is fixed to the cantilever 270 through a chain 273. Two tapered holes 285 are provided at the upper end of the spreader 280, and each of the tapered holes 285 is respectively connected in cooperation with the locking column 272 on the cantilever 270.

[0193] Specifically, as Figure 22 shown, the spreader 280 is fixed under the other end of the cantilever 270 through a chain 273. The spreader 280 is provided with two tapered holes 285, and these two tapered holes 285 cooperate with the locking column 272 of the cantilever 270. The locking column 272 extends and is inserted into the tapered hole 285 to lock the spreader 280. The locking column 272 is pulled out of the tapered hole 285 to unlock the spreader 280. The locked spreader 280 is placed to prevent shaking during movement. The unlocked spreader 280 floats through the chain 273, avoiding rigid contact when the spreader 280 grabs and lowers the battery, and at the same time, it can also tolerate errors, improving the success rate of battery swapping.

[0194] Therefore, in this embodiment, the spreader 280 floats through the chain 273, avoiding rigid contact between the battery frame and the vehicle-mounted bottom tray and the guiding column of the battery compartment 10. The impact of the spreader 280 on the cantilever 270 is greatly reduced, improving the service life of the battery swapping robot 13.

[0195] In this embodiment, the spreader 280 is used to hook the battery. Specifically, the spreader 280 includes a battery hook locking mechanism for connecting with the battery.

[0196] Specifically, in a possible implementation manner, the battery hook-locking mechanism is disposed at the lower end of the spreader 280. The battery hook-locking mechanism includes a spreader electric cylinder 282, a locking tongue 282, a lock hole fixing seat 283, a limiting block 284 for the locking tongue 282, and an electric cylinder fixing seat. The spreader electric cylinder 282 is hinged to the locking tongue 282 and drives the locking tongue 282 to extend and retract. The locking tongue 282 is internally disposed in the lock hole with a clearance fit. After the locking tongue 282 extends, it can hook the battery to realize the connection between the spreader 280 and the battery. After the locking tongue 282 retracts, the separation between the spreader 280 and the battery is realized.

[0197] It can be seen that in this embodiment, the battery swapping robot 13 has multiple degrees of freedom. The RGV cart is used to move in the X direction on the ground rail (heavy rail). The rotating platform is driven to rotate in the R direction by the helical slewing bearing. The helical gear and the rack cooperate with the linear guide slider to drive the translation stage to move in the Y direction. The lead screw transmission pair drives the lifting stage, the cantilever, and the spreader to move in the Z direction. The electric cylinder locking tongue mechanism and the secondary taper locking post are used to lock the battery box. The spreader is floated by the endless chain. With helical transmission and lead screw transmission, the battery swapping robot 13 has a high repeat positioning accuracy. The battery swapping robot 13 can perform X / Y / Z / R direction compound movements. The battery swapping beats can be carried out simultaneously, and the battery swapping time is greatly reduced, improving the battery swapping efficiency.

[0198] Therefore, the battery swapping robot 13 in this embodiment can effectively prevent the battery swapping robot 13 from tipping over. The overall equipment is more stable and reliable. In a high-load battery swapping scenario, the battery swapping robot 13 can work stably, continuously, and reliably for a long time, with a long maintenance cycle and simple maintenance. It can perform compound movements in X / Y / Z / R directions, has a high degree of freedom, a short battery swapping time, a high battery swapping efficiency, and high movement accuracy.

[0199] In summary, the battery compartment 10 of the heavy truck battery swapping station in this embodiment adopts a combined layout structure of arc and straight line, with a short battery swapping time and a high battery swapping efficiency. The battery swapping robot 13 can perform X / Y / Z / R direction compound movements. The battery swapping beats can be carried out simultaneously, and the battery swapping time is greatly reduced, improving the battery swapping efficiency.
