Related devices and working methods used in battery replacement equipment

[0001] This application claims priority to the Chinese patent application filed with the China Patent Office on March 29, 2024, with application number "202410380046.4" and invention name "Related devices and working methods applied to battery exchange equipment", all contents of which are incorporated by reference into this application. Technical Field

[0002] The present application relates to the field of battery swapping technology, and specifically to related devices and working methods used in battery swapping equipment. Background Art

[0003] With the development and popularization of new energy vehicles, battery pack quick-swap technology has also developed rapidly. For large vehicles, such as heavy trucks and light trucks, the heavy weight of the body and cargo leads to higher battery pack capacity requirements, requiring a sufficiently large capacity of electricity to support the operation of large vehicles.

[0004] In traditional battery swapping, large new energy vehicles use a top-lift method to secure large battery containers to the vehicle's beams. These containers are located close to the cab, posing significant safety risks to both the driver and the vehicle during operation and during top-lift battery swapping. Furthermore, battery failures can directly harm the driver. Furthermore, the top-lift method places high demands on the site for battery swap stations, requiring sufficient space for lifting equipment to transport and store batteries, resulting in high construction costs.

[0005] Therefore, for large vehicles, there is an urgent need for a safer, more reliable and easy-to-popularize battery swap mode. For example, a chassis-type battery swap mode for passenger cars is adopted. In the chassis-type battery swap mode, it is necessary to control the battery swap equipment to move as a whole to the battery swap position under the battery swap vehicle, and then perform lifting operations and remove or install battery pack operations to complete the entire battery swap process. In this battery swap process, due to the limited underground space of the battery swap vehicle, especially heavy truck battery swap vehicles, which are difficult to drive and park on platforms above the ground, the bottom space of the battery swap vehicle is more limited. If a battery swap device is used for battery swapping, the battery swap device needs to carry the depleted battery pack or the fully charged battery pack to move back and forth and in and out of the bottom of the battery swap vehicle during the battery swap process. In order to meet the power requirements of heavy truck battery swap vehicles, the battery packs are very large, which leads to a great restriction on the available space for the battery swap equipment. At this time, if you want to increase the available space for the battery swapping equipment, you can only move the battery swapping equipment in the space sunken from the ground. Due to the multiple driving of heavy-duty battery swapping vehicles before and after battery swapping, the ground structure under this method will inevitably become unreliable and difficult to bear the multiple loads of the battery swapping vehicles, reducing the life of the equipment structure and posing a safety hazard to the battery swapping vehicles.

[0006] This shows that the many drawbacks of the prior art need to be further improved and enhanced. Summary of the Invention

[0007] In order to solve at least one technical problem existing in the background technology, the present application provides a related device and working method applied to battery replacement equipment.

[0008] The technical solutions adopted in this application are:

[0009] The present application provides a battery exchange device, comprising: a fixed support frame, a battery exchange body arranged between the support frames and capable of being raised and lowered, and a battery exchange device arranged in the battery exchange body and capable of being telescopically moved to the outside of the support frame. The battery exchange device is telescopically moved and the battery exchange body is raised and lowered to achieve battery disassembly and assembly operations on the battery exchange vehicle and / or battery transfer operations between battery compartments of the battery rack.

[0010] The battery swap body can be raised and lowered on the support frame to adjust the height of the battery swap device. When the battery needs to be removed and installed, it is adjusted to the height corresponding to the car chassis and then extended. When a low-charged battery needs to be placed in the battery compartment for charging or a fully charged battery needs to be taken out of the battery compartment, it is adjusted to the height corresponding to the battery compartment and then extended to take and place the battery, thereby realizing battery disassembly and installation operations on the battery swap vehicle and / or battery transfer operations between the battery compartment positions of the battery rack.

[0011] As an embodiment of the present application, the battery exchange device includes a battery exchange device and a battery exchange mechanism arranged on the top surface of the battery exchange device. The battery exchange device drives the battery exchange mechanism to extend into the bottom of the battery exchange vehicle to exchange the battery pack.

[0012] The retractable function of the battery swapping device is realized by setting up a battery swapping device. During battery swapping, the battery swapping device drives the battery swapping mechanism to extend into the bottom of the battery swapping vehicle to swap the battery pack, thereby realizing battery disassembly and assembly operations on the battery swapping vehicle and / or battery transfer operations between the battery compartment positions of the battery rack.

[0013] As an embodiment of the present application, the battery replacement mechanism includes a floating battery tray and an unlocking pin provided on the battery tray;

[0014] The battery tray extends into the bottom of the battery-swapping vehicle through the telescopic movement of the battery-swapping device, and the unlocking pin unlocks or locks the battery pack as the battery tray rises and falls and the telescopic movement of the battery-swapping device.

[0015] The battery tray is used to support the battery pack during the battery swapping process. Under the telescopic movement of the battery swapping device, the battery tray extends into the bottom of the battery swapping vehicle. Since the battery tray is a floating design, the floating characteristics of the battery tray allow it to adapt to the shape and state of different battery swapping vehicle chassis, maintaining contact with the bottom of the vehicle, thereby achieving stable support for the battery pack. The unlocking pin is brought into contact with the unlocking point of the battery pack as the battery tray rises and falls and the telescopic movement of the battery swapping device, thereby unlocking or locking the battery pack, improving the accuracy and efficiency of disassembly and assembly of the battery pack.

[0016] As an embodiment of the present application, the battery exchange mechanism further includes a bracket, the battery tray is arranged higher than the bracket, and an elastic member is provided on the bracket for enabling the battery tray to float.

[0017] The bracket can support the battery tray and improve its stability. The elastic parts on the bracket make the battery tray floatable, which allows the battery tray to adapt to the shape and state of different battery-swapping vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving stability and safety during the battery swap process. In addition, the elastic parts can enable the battery tray to adapt to different surfaces and pressures when contacting the bottom of the battery-swapping vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery swapping, but also ensures the simplicity of battery swapping operations and the safe replacement of battery packs.

[0018] As an embodiment of the present application, the battery exchange mechanism further includes a bracket and a support plate arranged on the bracket, a sinking groove is formed on the support plate, and the battery tray is arranged in the sinking groove.

[0019] The battery tray is placed in the sunken groove on the pallet, which reduces the overall height of the battery tray on the bracket, makes the overall thickness of the battery swap mechanism smaller, and increases the battery swap space. In addition, the battery tray is placed in the sunken groove on the pallet, which can ensure the stable position of the battery tray during the battery swap process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery swap.

[0020] As an embodiment of the present application, the battery tray is further provided with at least two battery positioning pins;

[0021] The battery positioning pins are distributed in the middle area of ​​the battery tray along the length direction of the battery tray.

[0022] The positioning pins provided on the battery tray can ensure the correct position of the battery pack during the battery replacement process, prevent displacement during movement or battery replacement, and thus improve the accuracy and safety of battery replacement. In addition, through the cooperation between the battery positioning pins and the battery pack, a positioning and clamping effect is produced on the battery pack, so as to facilitate the synchronous movement of the battery pack, and also enable the battery pack to better withstand the unlocking force, thereby improving the stability of battery unlocking. As an embodiment of the present application, the battery replacement body includes a compartment and a mobile component provided between the support frames and capable of being lifted and moved along the support frames, the battery replacement device is provided in the compartment, and the compartment can be rotatably connected to the mobile component to adjust the direction of the battery replacement device.

At the same time, the car body and the moving component can be rotatably connected to facilitate the adjustment of the angle of the car body, thereby adjusting the extension angle of the battery exchange device. When the battery exchange electric vehicle is parked at a deflection angle, it can be accurately positioned and extended to achieve precise battery exchange.

[0024] The moving assembly includes at least two moving parts that are arranged in contact with the side walls of two adjacent columns and can be lifted and lowered, and a linkage part connected between the at least two moving parts. The box body can be rotatably connected to the bottom surface of the linkage part.

[0025] By setting up multiple columns on the outer periphery of the car body, the cooperation between the columns and the moving components enables the moving components to drive the car body to rise and fall, thereby adjusting the height of the battery replacement device. By setting up a moving part in the moving component to cooperate with the columns to achieve the lifting function, and by setting up a linkage part to be connected to the car body for rotation, it plays a role in positioning and supporting the car body. In addition, the moving component is set above the car body, and the rotation control is achieved by the top surface of the car body, so that the bottom surface of the car body does not need to be set up with any additional structure, and it can be set close to the ground, so that the battery at any chassis height position can be replaced, which improves the scope of application.

[0034] And / or, the first reinforcement structure includes a plurality of reinforcement plates arranged between the longitudinal beams, and a transition connection plate is further provided on the beam surface at the connection between the reinforcement plates and the longitudinal beams.

[0035] Since the compartment contains a battery exchange device, a battery will be placed on the battery exchange device during use. The first reinforcement part is provided to strengthen the structural strength of the linkage part to prevent deformation.

[0036] In one embodiment, the first reinforcement structure includes a plurality of reinforcement plates fixedly connected to the longitudinal beam and the mounting plate to enhance the structural strength of the entire linkage portion.

[0038] The fixed plate and the column are slidably connected by a slider and rail structure. Whether the slider and rail are located on the fixed plate or the column is not a specific requirement; both arrangements can achieve the desired lifting effect. At least two sliders are positioned sequentially along the lifting direction to define the sliding mechanism's trajectory, preventing deviation during lifting and ensuring stability.

[0039] As an embodiment of the present application, at least two rollers are provided on the two vertical side walls adjacent to the fixed plate and the column, and rolling surfaces that cooperate with the rollers are provided on the two mutually vertical side walls corresponding to the column. Another lifting and lowering cooperation structure adopts the cooperation between the rollers and the rolling surfaces to realize the lifting and lowering of the battery exchange body.

[0040] As an embodiment of the present application, the battery exchange body also includes a compartment, and a sliding mechanism is provided between the battery exchange device and the compartment to enable the battery exchange device to move relative to the compartment in a direction perpendicular to the telescopic direction.

[0041] The body is used to support and fix the battery-changing device, and the battery-changing device is used to extend out of the body to take out the low-charged battery removed from the tram and put it into the battery compartment for charging, and take out the fully charged battery in the battery compartment for easy installation on the tram. Taking into account that the tram that needs battery replacement may have position deviation when parked, a sliding mechanism is provided between the battery-changing device and the body, and the battery-changing device can be moved in a direction perpendicular to the telescopic direction according to the parking position of the tram, so as to align with the battery pack of the tram; on the other hand, the position of the battery-changing device can be adjusted for battery packs in different positions in the battery compartment, and batteries in different positions in the battery compartment can be taken and placed. As an embodiment of the present application, the sliding mechanism includes a fixed part provided in the body along a direction perpendicular to the telescopic direction and a movable part movably provided on the fixed part, and the battery-changing device includes a fixed part connected to the fixed part or the movable part and a telescopic part movably connected to the fixed part.

[0042] By providing a fixed part and a movable part in the sliding mechanism, the two structures cooperate to achieve the function of the battery swap device moving relative to the body in a direction perpendicular to the telescopic direction. The battery swap device is provided with a fixed part, which moves between the sliding mechanism and the body in a direction perpendicular to the telescopic direction, thereby driving the entire battery swap device to move relative to the body in a direction perpendicular to the telescopic direction. The fixed part is provided with a telescopic part, which can be extended outside the body to remove and place batteries. The telescopic movement function of the battery swap device is achieved by the movable connection between the telescopic part and the fixed part.

[0043] As an embodiment of the present application, the battery exchange equipment also includes a guide mechanism arranged between the body and the battery exchange device, and the guide mechanism includes a guide rail and a slider arranged in pairs, one of the guide rail and the slider is fixed to the body, and the other is fixed to the battery exchange device.

[0044] The guide mechanism is used to limit and guide the movement of the battery-exchanging device relative to the car body in a direction perpendicular to the telescopic direction. A pair of matching guide rails and sliders are provided in the guide mechanism. By fixing the slider to any one of the car body and the battery-exchanging device and fixing the other to the guide rail, a sliding fit between the guide rail and the slider is achieved, thereby achieving the role of limiting and guiding the movement of the battery-exchanging device relative to the car body in a direction perpendicular to the telescopic direction.

[0045] As an embodiment of the present application, the fixed part is a rack of a preset length, the movable part is a gear, the gear is provided on the battery exchange device, the rack is provided on the compartment, and the sliding mechanism also includes a drive motor provided on the battery exchange device for driving the gear to rotate.

[0046] By setting the fixed part as a rack of a preset length and the movable part as a gear that cooperates with the rack, the rack is fixed on the car body, and the gear is fixed on the battery exchange device. The gear and the rack are meshed. A driving motor is set on the battery exchange device to drive the gear to rotate. When the gear rotates, an interaction force is generated with the rack. Since the rack is fixed, the gear drives the battery exchange device to move relative to the car body in a direction perpendicular to the telescopic direction.

[0047] As an embodiment of the present application, the drive motor is connected to the adjacent fixed part through a fixed mounting plate, a mounting hole is provided on the fixed mounting plate, and the rotating shaft of the drive motor passes through the mounting hole and is connected to the gear; the bottom of the compartment frame includes a crossbeam arranged in a direction perpendicular to the telescopic direction of the battery exchange device, the rack is fixedly connected to the crossbeam, and the extension direction of the rack is perpendicular to the telescopic direction of the battery exchange device. The gear is driven to rotate by the drive motor so that it moves relative to the rack, thereby driving the battery exchange device to move synchronously.

[0048] The drive motor is fixedly connected to the fixed part of the battery replacement device through a fixed mounting plate, and a mounting hole is opened on the fixed mounting plate to facilitate the fixed connection between the output shaft of the drive motor and the gear to drive the gear to rotate;

[0049] Considering that the moving direction of the battery-exchanging device is perpendicular to the extension direction, the rack is fixed on a beam perpendicular to the extension direction of the battery-exchanging device, and the extension direction of the rack is perpendicular to the extension direction of the battery-exchanging device. When the gear rotates, it can only move in a direction perpendicular to the extension direction, thereby driving the battery-exchanging device to move in a direction perpendicular to the extension direction.

[0050] As an embodiment of the present application, both ends of the fixing part are slidably connected to the crossbeam through the guide mechanism, the two ends of the fixing part are located above the crossbeam, and the lower part of the fixing part includes a downwardly protruding limit base, and the two ends of the limit base are clamped between the two crossbeams.

[0051] The battery swap device is moved in a direction perpendicular to the telescopic direction through a sliding connection between the fixed part and the cross beam. In order to realize the above movement function and limit the movement trajectory of the battery swap device, a guide mechanism and a limit base are set. The guide mechanism includes a slider and a guide rail to realize the sliding connection between the fixed part and the battery swap device. The guide rail also limits the movement trajectory of the fixed part, and it can only move along the length direction of the guide rail. In order to further stabilize the movement trajectory of the battery swap device, a downward protruding limit base is provided on the fixed part, and the two ends of the limit base are clamped between the two cross beams to ensure that the battery swap device can only move in a direction perpendicular to the telescopic direction to prevent angle deviation and affect the accuracy of battery removal and placement.

[0052] As an embodiment of the present application, both of the two beams are provided with positioning grooves facing the fixed portion, the guide rail is at least partially located in the positioning groove, the slider is fixedly connected to the fixed portion, and the slider is slidably engaged with the guide rail.

[0053] By providing a positioning groove on the crossbeam for fixing the guide mechanism, the relative movement trajectory between the battery exchange device and the body is defined. Placing part or all of the guide rail in the guide mechanism in the positioning groove can effectively reduce the thickness of the body and the telescopic mechanism as a whole while improving the strength of the body. By sliding between the slider fixed on the fixed part and the guide rail, the battery exchange device can be moved in a direction perpendicular to the telescopic direction. In one embodiment, the guide rail and the slider are both contained in the positioning groove, and the slider is limited to prevent the slider from detaching from the guide rail. As an embodiment of the present application, the battery exchange device also includes two independent lifting drive mechanisms respectively arranged on both sides of the battery exchange body, the lifting drive mechanism includes a lifting motor, and the support frame includes a plurality of columns arranged around the battery exchange body, each of the columns is provided with a vertically movable counterweight block, the counterweight block is connected to the fixed plate on its corresponding side by a chain, and a sprocket is provided above each column to cooperate with the chain on its side for transmission. The lifting motor drives the synchronous shaft to rotate, thereby simultaneously driving the two chains on the same side of the battery exchange body to drive the moving part to move vertically.

[0054] Two independent lifting drive mechanisms are set up to independently control the lifting height on both sides of the battery swap body, so that the battery swap body can be tilted.

[0055] In actual operation, the chassis of a tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, the tilt angle of the extended part of the battery swap device needs to be adjusted. By independently controlling the lifting height of both sides of the battery swap body, the purpose of tilting the body is achieved. When the body tilts, the battery swap device inside the body is at the same tilt angle as the body, and the extended part can fit well with the tram chassis, allowing battery removal and transportation.

[0056] In one embodiment, the lifting drive mechanism includes a motor. This motor drives the synchronous shaft to rotate, thereby simultaneously driving two chains on the same side of the battery swap body, driving the sliding mechanism to move vertically. This controls the height and tilt angle of the battery swap device, allowing precise battery swapping operations to be performed in close contact with the vehicle chassis. By providing a counterweight, chain, and sprocket at each column and connecting them to the sliding mechanism on the corresponding side, the battery swap body can be raised and lowered synchronously on the same side.

[0057] As an embodiment of the present application, the counterweight block is located on the end side adjacent to or on the opposite side of the battery exchange body.

[0058] There are two settings for the counterweight. One is to be set on the end side adjacent to the battery swap body to facilitate the transportation of batteries between battery compartments. The other is to be set on the other side opposite to the battery swap body to optimize the space utilization efficiency of the battery swap station.

[0059] As an embodiment of the present application, the battery exchange body includes a compartment and a movable assembly provided between the support frames and capable of being lifted and moved along the support frames.

The lifting function is realized by setting a moving part in the moving assembly to cooperate with the support frame, and the positioning and support function of the car body are realized by setting a linkage part.

[0062] In one embodiment, the battery swap body is tilted by rotating the shaft and the through hole, and by moving the shaft and the waist-shaped hole. Whether the shaft, through hole, or waist-shaped hole are located in the battery swap body or the sliding mechanism is not specified; all are capable of achieving the effects of this technology.

[0063] As an embodiment of the present application, the linkage portion includes two beams with both ends respectively arranged corresponding to the columns, and the moving portion includes at least two sliders respectively attached to the side walls of the columns and a connecting rod connecting the sliders on both sides.

[0064] The linkage part is connected to the moving part by setting a crossbeam corresponding to the column. The moving part is connected to the column through a slider. The two sliders on the same side are connected and moved synchronously by setting a connecting rod to realize synchronous lifting of the same side of the car body.

[0065] As an embodiment of the present application, the rotating shaft is provided through the side walls of the beam near both ends, and a shaft sleeve is fixedly provided inside the beam to install the rotating shaft;

[0066] A U-shaped lug is provided on the side wall of the connecting rod facing the battery exchange body, and the through hole or the waist-shaped hole is provided on the lug side wall of the U-shaped lug.

[0067] A rotating shaft and a sleeve for mounting the rotating shaft are provided on the crossbeam. These shafts rotate with the through-holes on the connecting rods and slide with the waist-shaped holes to achieve tilting of the vehicle body and the internal battery exchange device. In this embodiment, a U-shaped lug is provided on the connecting rods, and the through-holes and the waist-shaped holes are arranged on the U-shaped lugs to achieve the connection between the crossbeam and the connecting rods.

[0068] In an actual working environment, the chassis of the tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, it is necessary to adjust the tilt angle of the protruding part of the battery exchange device. By rotatably connecting one end of the crossbeam to the corresponding connecting rod and movably connecting the other end to the corresponding connecting rod, it is possible to raise the two sides of the car body to different heights, thereby achieving the purpose of tilting the car body. When the car body is tilted, the battery exchange device in the car body is at the same tilt angle as the car body, and the protruding part can be well attached to the tram chassis for battery removal and transportation. As an embodiment of the present application, a U-shaped lug is provided on the side wall near the two ends of the connecting rod, and a rotating shaft is passed through the U-shaped lug. Connectors that match the spacing between the two sliding mechanisms are respectively provided at both ends of the crossbeam. A through hole or a movable groove is provided on the connecting member. The through hole is a circular hole that passes through the connecting member and matches the rotating shaft, and the movable groove is a waist-shaped hole that extends along the length direction of the crossbeam and passes through the connecting member.

[0072] The first battery rack and the support frame reuse the columns; or, the first battery rack and the support frame are independent of each other.

[0073] In one embodiment, the battery swapping equipment can be arranged on one or both sides of the battery swapping platform along the driving direction of the battery swapping vehicle, so that single-sided and / or double-sided battery swapping can be realized, thereby improving the battery swapping efficiency; the battery swapping mechanism in the battery swapping equipment can be rotatable, so that the arrangement of the above-mentioned battery storage device is more flexible and more scalable. Preferably, the above-mentioned first battery rack can be arranged around the circumference of the battery swapping equipment, thereby improving space utilization and increasing battery storage capacity; the reuse of columns between the first battery rack and the support frame can shorten the battery transfer distance between the first battery rack and the battery swapping equipment, thereby further improving the battery swapping efficiency, and at the same time can also simplify the equipment structure, save installation space and equipment costs.

[0074] As an embodiment of the present application, the battery storage device further includes a second battery storage device provided on a side of the battery swapping device opposite to the battery swapping platform, the second battery storage device including at least one row of second battery racks arranged toward the battery swapping device, the second battery racks being provided with a plurality of second battery compartments in sequence along the vertical direction;

[0075] The second battery storage device also includes a third battery rack arranged on at least one side of the second battery rack in a direction parallel to the driving direction of the battery-exchange vehicle. The third battery rack has at least one third battery compartment in any horizontal direction. A battery conveying mechanism is arranged between the third battery compartment and the second battery compartment position at the same vertical height. The battery conveying mechanism can transfer battery packs between the second battery compartment and the third battery compartment.

[0076] In the above scheme, the arrangement of the second battery rack and the third battery rack can further utilize the installation space around the battery swapping equipment, and the arrangement of the battery conveying mechanism can enable the transfer of fully charged batteries or low-charged batteries between the third battery rack and the battery swapping equipment by conveying the batteries to the second battery rack, thereby increasing the battery storage space and the number of available batteries in the battery swapping station, effectively utilizing the space in the battery swapping station, and increasing the battery swapping scale of the battery swapping station.

[0077] As one embodiment of the present application, the first battery rack is independent of the support frame, and the support frame can rotate relative to the battery storage device. In the above solution, the independence of the support frame and the first battery rack facilitates the support frame to drive the rotation of the vehicle body as a whole, allowing the extension mechanism and the battery replacement mechanism to operate, which also makes the installation method of the first battery rack more flexible.

[0078] As an embodiment of the present application, when the opening faces the hatch of the battery compartment, the column is arranged outside the horizontal projection range of the opening and / or the hatch.

[0079] This setting can further prevent the pillars from interfering with the rotation of the car body and the extension of the extension mechanism / battery replacement mechanism outside the car body, ensuring smooth battery replacement.

[0080] As an embodiment of the present application, the first battery rack is arranged on both sides of the battery swapping device in a direction parallel to the driving direction of the battery swapping vehicle;

[0081] The first battery rack is fixed, and the second battery rack and the third battery rack can be moved relative to the battery exchange equipment in a direction parallel to the driving direction of the battery exchange vehicle. In the above scheme, the first battery rack and the second battery rack are arranged at a 90° angle on the periphery of the battery exchange equipment. This arrangement makes the single rotation angle of the compartment fixed, which is more convenient for controlling the rotation of the compartment; the second battery rack and the third battery rack can be moved relative to the battery exchange equipment, so when the second battery rack is fully loaded, the second battery rack can be removed, and the third battery rack can be moved to the position of the original second battery rack for standby use, which is beneficial to improving the overall utilization efficiency of the battery storage device. Of course, the relative angle between the first battery rack and the second battery rack can also be adjusted, so that the first battery rack, the second battery rack and the battery exchange platform can be arranged in a pentagon, hexagon or other different arrangements around the battery exchange equipment.

[0082] As an embodiment of the present application, the battery compartment includes a support beam for supporting the battery pack, the support beam is located in the top area of ​​the battery compartment, and the battery pack is suspended and fixed on the support beam;

[0083] Alternatively, the support beam is located in the bottom area of ​​the battery compartment, and the battery pack is supported and placed on the support beam.

[0084] The battery pack is fixed in a suspended manner on the support beam, which is the same as the way the battery pack is fixed on the chassis of the battery swap vehicle. This design allows for easy replacement and maintenance of the battery pack, while also effectively utilizing the space in the battery compartment. The battery pack is supported on the support beam in the bottom area of ​​the battery compartment. This layout helps stabilize the battery pack and simplify the battery loading and unloading process, improving the convenience and safety of storing and accessing the battery pack.

[0085] As an embodiment of the present application, when the bolster is located in the top area of ​​the battery compartment, a battery locking mechanism is provided on the bolster;

[0086] The unlocking pin unlocks or locks the battery locking mechanism as the battery tray rises and falls and the battery replacement device moves telescopically.

[0087] The battery locking mechanism not only fixes the battery pack, but its unlocking and locking principles are the same as those of the battery pack on the battery swap vehicle. The same operation can be used to take or place the battery pack in the battery compartment without adding additional mechanisms or equipment, reducing costs. Therefore, the versatility of the battery swap mechanism in storing and retrieving batteries in the battery compartment and removing and installing batteries at the bottom of the battery swap vehicle is improved, greatly improving the efficiency of battery swapping. As an embodiment of the present application, the battery rack is provided with an electrical connection device, and the interface end of the electrical connection device corresponds to the bay opening of the battery compartment;

[0088] The battery locking mechanism is suitable for fixing the battery pack. When the battery pack is moved to be locked with the battery locking mechanism, the charging port of the battery pack is electrically connected to the interface end of the electrical connection device.

[0089] The electrical connection device can charge the battery pack placed on the battery compartment. Furthermore, after the battery locking mechanism fixes the battery pack, the interface end of the battery pack can be docked with the electrical connection device. This design ensures that the battery pack can be safely charged in the locked state, and is also convenient for management and maintenance.

[0090] A battery swapping method, based on the battery swapping station described above, comprises the following steps:

[0091] Step 1: Before the battery swap vehicle enters the battery swap platform and / or after it parks on the battery swap platform, obtain the vehicle model information of the battery swap vehicle; after the battery swap vehicle parks in place, obtain the position information of the battery swap vehicle along the length direction of the vehicle body;

[0092] Step 2: Based on the vehicle model information, control the movement of the vehicle body relative to the support frame so that the battery swap mechanism corresponds to the battery pack installation area of ​​the battery swap vehicle or the fully charged battery compartment on the battery rack in the vertical direction;

[0093] Step 3: Based on the vehicle model information and the position information, control the movement of the sliding mechanism to move the battery swap mechanism on the battery swap device relative to the compartment along the vehicle body direction and make the battery swap mechanism correspond to the battery pack installation area of ​​the battery swap vehicle along the vehicle body direction;

[0094] Step 4: Based on the vehicle model information and the location information, control the battery swap device to drive the battery swap mechanism to extend toward the battery swap vehicle to below the battery pack installation area and control the battery swap mechanism to remove the low-charged battery from the battery swap vehicle; or control the battery swap device to drive the battery swap mechanism to extend toward the battery rack and control the battery swap mechanism to remove the fully charged battery from the fully charged battery compartment;

[0095] Based on the vehicle model information and the location information, the battery swapping device is controlled to drive the battery swapping mechanism to extend toward the battery rack and the battery swapping mechanism is controlled to place the depleted battery on the battery rack; or, the battery swapping device is controlled to drive the battery swapping mechanism to extend toward the battery swapping vehicle to the bottom of the battery pack installation area and the battery swapping mechanism is controlled to install the fully charged battery on the battery swapping vehicle.

[0096] In the above scheme, before the battery-swapping vehicle enters the battery-swapping platform and / or after it parks on the battery-swapping platform, the vehicle model information of the battery-swapping vehicle is obtained, which facilitates pre-fetching of the fully charged battery of the corresponding model according to the vehicle model information before performing the battery-swapping operation. This can fully utilize the parking time of the battery-swapping vehicle, improve the battery-swapping efficiency, and bring users a better battery-swapping experience. At the same time, the above-mentioned battery-swapping steps can be used to align the battery pack of the battery-swapping vehicle according to the vehicle information and vehicle position information of the battery-swapping vehicle, and adapt to the deviation of the parking position of different vehicles along the driving direction. The battery-swapping steps in the entire battery-swapping process are simple and efficient, and the above-mentioned battery-swapping steps enable the battery-swapping station to realize single-sided / double-sided battery-swapping, and can also adapt to the battery-swapping needs of different models, with higher battery-swapping efficiency and greater versatility.

[0097] As an implementation method of this application, step three includes:

[0098] s1, controlling the battery swapping device to drive the battery swapping mechanism to extend toward the battery swapping vehicle to a preset position;

[0099] s2, controls the movement of the sliding mechanism so that the battery-exchanging device drives the battery-exchanging mechanism to move from the preset position along the direction of the vehicle body relative to the compartment and makes the battery-exchanging mechanism correspond to the battery pack installation area along the direction of the vehicle body.

[0100] The battery swapping device first drives the battery swapping mechanism to extend to the predetermined position, which can provide sufficient displacement space for the subsequent sliding mechanism to drive the battery swapping device and the battery swapping mechanism to move along the direction of the vehicle body, thereby avoiding the battery swapping mechanism and / or the battery swapping device from interfering with the compartment during the movement along the direction of the vehicle body, and can not only accurately correspond the battery swapping mechanism to the battery pack installation area of ​​the battery swapping vehicle, but also ensure the safe operation of the equipment.

[0101] As an implementation method of this application, the step 4 includes:

[0102] a1, based on the vehicle model information and the location information, controlling the battery swap device to move so that the battery swap device drives the battery swap mechanism to extend toward the battery swap vehicle to below the battery pack installation area;

[0103] b1, controlling the battery replacement mechanism to unlock and remove the deflated battery installed in the battery pack installation area and to carry the deflated battery;

[0104] c1, controlling the battery-swapping device to drive the battery-swapping mechanism and the battery-swapping mechanism carrying the depleted battery to retract into the interior of the compartment;

[0105] d1, controlling the carriage to rotate relative to the support frame so that the battery exchange mechanism faces the battery rack;

[0106] e1, controlling the carriage to move vertically relative to the support frame, controlling the sliding mechanism to move the battery-swapping mechanism relative to the carriage, so that the battery-swapping mechanism corresponds to an empty battery compartment on the battery rack, controlling the battery-swapping device to drive the battery-swapping mechanism and the depleted battery carried by the battery-swapping mechanism to extend toward the battery rack, and controlling the battery-swapping mechanism to place the depleted battery in the empty battery compartment;

[0107] f1, controlling the movement of the battery-swapping device to drive the battery-swapping mechanism to retract into the compartment, and controlling the compartment to move vertically relative to the support frame so that the battery-swapping mechanism corresponds to the fully charged battery compartment on the battery rack;

[0108] g1, controlling the battery-swapping device to move the battery-swapping mechanism toward the battery rack and controlling the battery-swapping mechanism to remove the fully-charged battery from the fully-charged battery compartment;

[0109] h1, controlling the movement of the battery-swapping device to drive the battery-swapping mechanism and the battery-swapping mechanism carrying the fully charged battery to retract into the interior of the compartment, and controlling the compartment to rotate relative to the support frame so that the battery-swapping mechanism faces the battery-swapping vehicle;

[0110] i1, controlling the movement of the compartment relative to the support frame so that the battery swap mechanism corresponds to the battery pack installation area in the vertical direction;

[0111] j1, controlling the battery swapping device to move the battery swapping mechanism and the fully charged battery to extend below the battery pack installation area, and controlling the battery swapping mechanism to move the fully charged battery to facilitate installation in the battery pack installation area;

[0112] k1, controls the movement of the battery exchange device to drive the battery exchange mechanism to retract into the compartment.

[0113] In the above scheme, the battery swapping equipment can complete the single battery swapping function of the battery swapping vehicle by sequentially completing the actions of removing the depleted battery - discharging the depleted battery - taking out the fully charged battery - installing the fully charged battery. This working sequence can adapt to the battery swapping needs of most vehicles, has strong versatility, and can greatly improve the battery swapping efficiency in conjunction with the battery storage device arranged around the battery swapping equipment.

[0114] As an embodiment of the present application, the battery swap mechanism includes a first battery swap mechanism and a second battery swap mechanism provided at both ends of the battery swap device along the telescopic direction of the battery swap device; the step four includes:

[0115] a2. Based on the vehicle model information and the location information, control the battery swap device to move so that the battery swap device drives the first battery swap mechanism to extend toward the fully charged battery compartment of the battery rack and control the first battery swap mechanism to take out the fully charged battery from the fully charged battery compartment and carry the fully charged battery;

[0116] b2, controlling the battery-swapping device to drive the first battery-swapping mechanism and the fully charged battery to retract into the compartment;

[0117] c2, controlling the carriage to move vertically relative to the support frame so that the second battery exchange mechanism corresponds to the battery pack installation area in the vertical direction and the direction of the vehicle body;

[0118] d2, controlling the battery-swapping device to move the second battery-swapping mechanism toward the battery-swapping vehicle and extending it to the battery pack installation area, controlling the second battery-swapping mechanism to unlock and remove the depleted battery installed in the battery pack installation area, and carrying the depleted battery;

[0119] e2, controlling the battery-swapping device to drive the second battery-swapping mechanism and the depleted battery to retract into the interior of the compartment;

[0120] f2, controlling the body to rotate relative to the support frame so that the first battery-swapping mechanism and the fully charged battery face the battery-swapping vehicle;

[0121] g2, controlling the carriage to move vertically relative to the support frame and repeating step ss, so that the first battery exchange mechanism corresponds to the battery pack installation area in the vertical direction and the direction of the vehicle body;

[0122] h2, controlling the battery swapping device to move the first battery swapping mechanism and the fully charged battery toward the battery swapping vehicle to below the battery pack installation area, and controlling the first battery swapping mechanism to move the fully charged battery to facilitate installation in the battery pack installation area;

[0123] i2, controlling the operation of the battery-swapping device to retract the first battery-swapping mechanism into the compartment;

[0124] j2, controlling the carriage to move vertically relative to the support frame so that the second battery-exchanging mechanism corresponds to the empty battery compartment on the battery rack, controlling the battery-exchanging device to drive the second battery-exchanging mechanism and the low-power battery to extend toward the battery rack, and controlling the second battery-exchanging mechanism to place the low-power battery in the empty battery compartment;

[0125] k2, controls the movement of the battery exchange device to drive the second battery exchange mechanism to retract into the compartment.

[0126] In the above scheme, the battery swapping equipment immediately takes the appropriate fully charged battery after obtaining the battery swapping vehicle information. After the battery swapping vehicle is parked in place, it directly performs the operation of removing the low-charged battery - retracting the low-charged battery - switching the position so that the fully charged battery is aligned with the battery swapping vehicle - installing the fully charged battery to the battery swapping vehicle - retracting and transferring the low-charged battery to the battery compartment

[0127] As an embodiment of the present application, perpendicular to the vehicle body direction, the distance between the preset position and the compartment is smaller than the distance between the battery-swap vehicle and the compartment.

[0128] Setting the above-mentioned preset position can provide sufficient displacement space for the subsequent sliding mechanism to drive the battery swap device and the battery swap mechanism to move along the direction of the vehicle body, avoiding the interference of the battery swap mechanism and / or the battery swap device with the compartment during the movement along the direction of the vehicle body, and can not only ensure the precise correspondence between the battery swap mechanism and the battery pack installation area of ​​the battery swap vehicle, but also ensure the safe operation of the equipment; and the preset position is set between the battery swap vehicle and the compartment, which is also convenient for more intuitive monitoring of the relative position between the battery swap mechanism and the battery swap vehicle, which is conducive to more accurate completion of the battery swap action.

[0129] As an embodiment of the present application, the position information includes the vehicle body length direction position, vehicle body width direction position and vehicle body height direction position,

[0130] In the step 4, the movement of the sliding mechanism is controlled based on the longitudinal position of the vehicle body;

[0131] In the step four, the battery exchange device is controlled based on the width direction position of the vehicle body to drive the battery exchange mechanism to extend below the battery pack installation area.

[0132] By collecting and identifying the above information, the actions of the battery replacement device, sliding mechanism and battery replacement mechanism in the above scheme can be controlled more accurately, thereby improving the efficiency and completion rate of each step of the action, which is beneficial to improving the overall battery replacement efficiency.

[0133] The present application also provides a battery transport device, comprising: a compartment and a telescopic mechanism disposed in the compartment and capable of being telescoped and moved outward. The battery transport device also comprises a sliding mechanism disposed between the telescopic mechanism and the compartment, so that the telescopic mechanism can move relative to the compartment in a direction perpendicular to the telescopic direction.

[0134] The body supports and secures the telescopic mechanism, which extends outside the body to retrieve depleted batteries removed from the tram and place them in the battery compartment for charging, and to remove fully charged batteries from the compartment for installation on the tram. Considering the potential for misalignment when a tram requiring battery replacement is parked, a sliding mechanism is provided between the telescopic mechanism and the body. This allows the mechanism to be moved perpendicular to the telescopic direction, depending on the tram's parking position, to align the mechanism with the tram's battery pack. Furthermore, the telescopic mechanism can be adjusted to accommodate battery packs located at different locations within the compartment, allowing for access and placement of batteries.

[0135] The sliding mechanism includes a fixed part arranged in the compartment along a direction perpendicular to the telescopic direction and a movable part movably arranged on the fixed part. The telescopic mechanism includes a fixed part connected to the fixed part or the movable part and a telescopic part movably connected to the fixed part.

[0136] By providing a fixed part and a movable part within the sliding mechanism, the two structures cooperate to achieve the telescopic mechanism's ability to move relative to the body in a direction perpendicular to the telescopic direction. The telescopic mechanism is provided with a fixed portion that moves perpendicularly between the sliding mechanism and the body, thereby driving the entire telescopic mechanism to move relative to the body in a direction perpendicular to the telescopic direction. A telescopic portion is provided above the fixed portion, which can extend outside the body to access batteries. The telescopic portion's removable connection with the fixed portion enables the telescopic mechanism's telescopic movement.

[0137] The battery transport device also includes a guide mechanism arranged between the compartment and the telescopic mechanism, and the guide mechanism includes a guide rail and a slider arranged in pairs, one of the guide rail and the slider is fixed to the compartment, and the other is fixed to the telescopic mechanism.

[0138] The guide mechanism is used to play a role of limiting and guiding the movement of the telescopic mechanism relative to the car body in a direction perpendicular to the telescopic direction. A pair of matching guide rails and sliders are provided in the guide mechanism. By fixedly connecting the slider to any one of the car body and the telescopic mechanism and fixing the other to the guide rail, a sliding fit between the guide rail and the slider is achieved, thereby achieving the role of limiting and guiding the movement of the telescopic mechanism relative to the car body in a direction perpendicular to the telescopic direction.

[0139] The fixing member is a rack of a preset length, the moving member is a gear, the gear is arranged on the telescopic mechanism, the rack is arranged on the box body, and the sliding mechanism also includes a driving motor arranged on the telescopic mechanism for driving the gear to rotate.

[0140] By specifically setting the fixed part to a rack of a preset length, and setting the movable part to a gear that cooperates with the rack, the rack is fixed on the car body, and the gear is fixed on the telescopic mechanism, the gear and the rack are meshed, and a driving motor is set on the telescopic mechanism to drive the gear to rotate. When the gear rotates, an interaction force is generated with the rack. Since the rack is fixed, the gear drives the telescopic mechanism to move relative to the car body in a direction perpendicular to the telescopic direction.

[0141] The present application also provides a battery replacement device, including the battery transfer device described in any embodiment of the first aspect above.

[0142] The battery exchange device provided in the embodiment of the second aspect of the present application includes the battery transfer device in any embodiment of the first aspect above, wherein, in the battery transfer device, the compartment is used to support and fix the telescopic mechanism, and the telescopic mechanism is used to extend out of the compartment to take out the low-power battery removed from the tram and put it into the battery compartment for charging, and take out the fully charged battery in the battery compartment for easy installation on the tram. Taking into account that the tram that needs to be replaced may have position deviation when parked, a sliding mechanism is set between the telescopic mechanism and the compartment, and the telescopic mechanism can be moved in a direction perpendicular to the telescopic direction according to the parking position of the tram, so as to align with the battery pack of the tram; on the other hand, the position of the telescopic mechanism can be adjusted for battery packs in different positions in the battery compartment, and batteries in different positions in the battery compartment can be taken and placed. Fully charged batteries are convenient for installation in different positions.

[0143] The battery-exchanging equipment also includes a battery-exchanging mechanism disposed on the top surface of the telescopic mechanism, which drives the battery-exchanging mechanism to extend into the bottom of the battery-exchanging vehicle to replace the battery pack.

[0144] During battery swapping, the battery swap mechanism, located on top of the telescopic mechanism, can be extended directly into the bottom of the vehicle to perform the swap. This not only improves battery swapping efficiency but also makes the swapping operation simpler and faster. The entire battery swapping equipment combines battery removal, installation, and transport functions, ensuring the rapid and safe replacement of battery packs, which is crucial for improving the ease of use and maintenance efficiency of electric vehicles.

[0145] The present application also provides a battery transfer device, comprising: a fixed support frame, a liftable and movable body, and a telescopic mechanism disposed in the body and capable of being telescoped and moved outward. The battery transfer device also comprises a movable component disposed between the support frames and capable of being lifted and lowered along the support frames. The body can be rotatably connected to the movable component to adjust the direction of the telescopic mechanism.

[0146] The height of the telescopic mechanism can be adjusted by setting a movable assembly to move the box up and down along the support frame. At the same time, the box and the movable assembly can be rotatably connected to facilitate the adjustment of the angle of the box, and thus the extension angle of the telescopic mechanism. When the position of the battery to be transported is deflected, the rotation adjustment can accurately position and extend the telescopic mechanism, effectively transporting the battery.

[0147] The moving assembly is arranged above the box body, and the top surface of the box body can be rotatably connected to the bottom surface of the moving assembly, so that the box body drives the telescopic mechanism to rotate synchronously, thereby adjusting the direction of the telescopic mechanism.

[0148] By setting the mobile component above the box and realizing rotation control by the top surface of the box, the bottom surface of the box does not need any additional structure and can be set close to the ground, thereby improving the scope of application for transporting batteries at any height.

[0149] The support frame includes a plurality of columns formed on the outer periphery of the box.

[0150] The moving assembly includes at least two moving parts that are arranged in contact with the side walls of two adjacent columns and can be lifted and lowered, and a linkage part connected between the at least two moving parts. The box body can be rotatably connected to the bottom surface of the linkage part.

[0151] By providing multiple columns on the outer periphery of the box, the columns cooperate with the moving assembly to enable the moving assembly to drive the box up and down, thereby adjusting the height of the telescopic mechanism. The moving assembly is provided with a moving part that cooperates with the columns to achieve the lifting function, and the linkage part is provided to connect with the box for rotation, which plays a role in positioning and supporting the box.

[0152] The linkage portion includes at least two cross beams whose ends are respectively connected to the corresponding moving portions and at least two longitudinal beams connected between the at least two cross beams. The bottom surfaces of the at least two longitudinal beams are formed with mounting surfaces for mounting the car body.

[0153] The linkage part is provided with at least two cross beams for connecting with the moving parts on both sides. At least two longitudinal beams are provided to form a mounting surface for mounting the compartment body. At the same time, the longitudinal beams also strengthen the overall structural strength of the linkage part to prevent deformation.

[0154] The battery transport device further includes a rotating mechanism disposed between the compartment and the linkage portion.

[0155] The rotatable connection between the car body and the linkage part is achieved through a rotating mechanism.

[0156] The present application also provides a battery storage device, comprising the battery transfer device of any embodiment of the first aspect as described above; the battery storage device also includes at least one battery rack arranged on the periphery of the battery transfer device, the battery rack being provided with a plurality of battery positions distributed longitudinally, and the battery positions having a position opening facing the compartment body.

[0157] In the above scheme, the battery rack is set up flexibly and has strong scalability. It can adapt to the installation conditions of different installation environments, improve space utilization, and increase the storage capacity of battery packs. The circumferential arrangement of multiple battery racks around the battery transfer device can make full use of the installation space on the side of the battery transfer device, and by cooperating with the rotatable compartment, the battery transfer device can interact with battery racks at any position for battery packs, thereby improving battery transfer efficiency.

[0158] There are multiple battery racks, and the multiple battery racks are arranged around the circumference of the battery transport device. The battery racks and the support frame reuse the columns; or the battery racks and the support frame are independent of each other.

[0159] In one embodiment, three battery racks are arranged at a 90° angle around the battery exchange equipment. This arrangement fixes the single rotation angle of the car body, which is more convenient for controlling the rotation of the car body. Of course, the relative angles between the battery racks can also be adjusted, so that the battery racks and the battery exchange platform can be arranged in more different arrangements such as pentagons and hexagons around the battery exchange equipment. In the above scheme, the reuse of columns by the battery rack and the support frame further improves the structural strength between the battery rack and the battery transfer device, which is beneficial to improving the safety of battery transfer. At the same time, this arrangement is conducive to simplifying the structure of the battery rack and / or support frame, saving equipment costs. The independence of the battery rack and the support frame facilitates the overall rotation of the battery transfer device, avoids interference of the columns with the rotation of the car body, and is more conducive to the flexible turning of the car body and the flexible arrangement of the battery rack.

[0160] The present application provides a battery exchange device, comprising: a support frame, a battery exchange body arranged between the support frames and capable of being raised and lowered, and a battery exchange device arranged in the battery exchange body and capable of being telescopically moved to the outside of the support frame. The battery exchange device also includes a plurality of sliding mechanisms slidably arranged on the side walls of a plurality of columns of the support frame. The battery exchange body is connected between the plurality of sliding mechanisms, and one end of the battery exchange body is rotatably connected to the corresponding sliding mechanism, and the other end is movably connected to the corresponding sliding mechanism.

[0161] The battery exchange body can be raised and lowered on the support frame. Specifically, it is connected by sliding multiple sliding mechanisms to adjust the height of the battery exchange device. When the battery needs to be removed and installed, it is adjusted to the height corresponding to the car chassis and then extended. When a low-charged battery needs to be placed in the battery compartment for charging or a fully charged battery needs to be taken out of the battery compartment, it is adjusted to the corresponding height of the battery compartment and then extended to take and place the battery.

[0162] In actual working environments, the chassis of a tram may have a certain tilt angle and is not horizontal. To adapt to the tilt angle of the tram chassis, the tilt angle of the extended portion of the battery swap device needs to be adjusted. One end of the battery swap body is rotatably connected to the corresponding sliding mechanism, and the other end is movably connected to the corresponding sliding mechanism. By making the two sides of the battery swap body present at different heights, the extended portion of the battery swap device can be well fitted to the tram chassis, facilitating battery removal and transportation.

[0163] A rotating shaft is provided on the end face of one of the battery exchange body and the sliding mechanism, and a through hole or a waist-shaped hole is provided on the end face of the other, thereby realizing a rotating connection or a movable connection between the battery exchange body and the sliding mechanism.

[0164] In one embodiment, the battery swap body is tilted by rotating the shaft and the through hole, and by moving the shaft and the waist-shaped hole. Whether the shaft, through hole, or waist-shaped hole are located in the battery swap body or the sliding mechanism is not specified; all are capable of achieving the effects of this technology.

[0165] The support frame includes a plurality of columns respectively arranged on the sides of the battery replacement body.

[0166] The plurality of sliding mechanisms are respectively provided corresponding to two adjacent columns.

[0167] The battery exchange body includes a compartment provided with the battery exchange device and a mounting portion provided on the top surface of the compartment, and the mounting portion is connected between the plurality of sliding mechanisms.

[0168] By setting up multiple columns around the battery swap body, the battery swap body can be raised and lowered through the cooperation between the columns and the sliding mechanism, thereby adjusting the height of the battery swap device. The battery swap device is fixedly supported by the box body, and the upper part of the box body is connected to the sliding mechanism through the mounting part, so that the box body and the battery swap device inside can be raised and lowered by the sliding mechanism.

[0169] The battery exchange equipment also includes two independent lifting drive mechanisms respectively arranged on both sides of the battery exchange body.

[0170] Two independent lifting drive mechanisms are set up to independently control the lifting height on both sides of the battery swap body, so that the battery swap body can be tilted.

[0171] In actual operation, the chassis of a tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, the tilt angle of the extended part of the battery swap device needs to be adjusted. By independently controlling the lifting height of both sides of the battery swap body, the purpose of tilting the body is achieved. When the body tilts, the battery swap device inside the body is at the same tilt angle as the body, and the extended part can fit well with the tram chassis, allowing battery removal and transportation.

[0172] The battery exchange equipment also includes a counterweight block, and the lifting drive mechanism includes a motor. Each of the columns is provided with a vertically movable counterweight block, and the counterweight block is connected to the sliding mechanism on its corresponding side through a chain. A sprocket is provided above each column to cooperate with the chain on its side for transmission. The motor drives the synchronous shaft to rotate, thereby simultaneously driving the two chains located on the same side of the battery exchange body to drive the sliding mechanism to move vertically.

[0173] In one embodiment, the lifting drive mechanism includes a motor. This motor drives the synchronous shaft to rotate, thereby simultaneously driving two chains on the same side of the battery swap body, driving the sliding mechanism to move vertically. This controls the height and tilt angle of the battery swap device, allowing precise battery swapping operations to be performed in close contact with the vehicle chassis. By providing a counterweight, chain, and sprocket at each column and connecting them to the sliding mechanism on the corresponding side, the battery swap body can be raised and lowered synchronously on the same side.

[0174] There are four upright posts, and the mounting portion includes two beams with two ends respectively arranged corresponding to the upright posts;

[0175] The sliding mechanism includes at least two sliding blocks respectively attached to the side walls of the column and a connecting rod connecting the sliding blocks on both sides.

[0176] The mounting portion is connected to the slider corresponding to the side wall of the column in the sliding mechanism by setting a crossbeam corresponding to the column. The sliding mechanism is slidably connected to the column through the slider. The two sliders on the same side are connected and moved synchronously by setting a connecting rod, thereby realizing synchronous lifting of the same side of the car body.

[0177] The present application also provides a battery swapping device, including a telescopic mechanism and a floating battery tray arranged on the telescopic mechanism. An unlocking pin is provided on the battery tray. The battery tray is extended into the bottom of the battery swapping vehicle through the telescopic movement of the telescopic mechanism. The unlocking pin unlocks or locks the battery pack as the battery tray rises and falls and the telescopic movement of the telescopic mechanism.

[0178] In one embodiment, the battery tray is used to support the battery pack during the battery swapping process. Under the telescopic movement of the battery swapping device, the battery tray extends into the bottom of the battery swapping vehicle. Since the battery tray is a floating design, the floating characteristics of the battery tray allow it to adapt to the shape and state of different battery swapping vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack. The unlocking pin abuts the unlocking point of the battery pack as the battery tray rises and falls and the telescopic movement of the battery swapping device, thereby unlocking or locking the battery pack, thereby improving the accuracy and efficiency of disassembly and assembly of the battery pack.

[0179] Furthermore, the battery exchange device also includes a bracket, the battery tray is arranged higher than the bracket, and the bracket is provided with an elastic member for enabling the battery tray to float.

[0180] In one embodiment, the bracket can support the battery tray and improve the stability of the battery tray. The elastic member on the bracket makes the battery tray floatable, which allows the battery tray to adapt to the shape and state of different battery swap vehicle chassis and maintain contact with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving the stability and safety of the battery swap process. In addition, the elastic member can enable the battery tray to adapt to different surfaces and pressures when contacting the bottom of the battery swap vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery swapping, but also ensures the simplicity of battery swapping operations and the safe replacement of battery packs.

[0181] Furthermore, the battery exchange equipment also includes a bracket and a support plate arranged on the bracket, a sinking groove is formed on the support plate, and the battery tray is arranged in the sinking groove.

[0182] In one embodiment, the battery tray is placed in a sunken groove on the pallet, which reduces the overall height of the battery tray on the bracket, makes the overall thickness of the battery swap mechanism smaller, and increases the battery swap space. In addition, the battery tray is placed in the sunken groove on the pallet, which can ensure the stable position of the battery tray during the battery swap process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery swap.

[0183] Furthermore, at least two battery positioning pins are provided on the battery tray; the battery positioning pins are distributed in the middle area of ​​the battery tray along the length direction of the battery tray.

[0184] In one embodiment, positioning pins on the battery tray ensure the correct position of the battery pack during battery swapping, preventing it from shifting during movement or swapping, thereby improving the accuracy and safety of battery swapping. Furthermore, the battery positioning pins cooperate with the battery pack to create a positioning and clamping effect on the battery pack, facilitating synchronous movement of the battery pack. This also makes the battery pack more resilient to unlocking forces, improving the stability of battery unlocking.

[0185] Furthermore, the battery exchange device further comprises a compartment, and the telescopic mechanism is slidably disposed within the compartment;

[0186] Wherein, the sliding direction of the telescopic mechanism is perpendicular to the telescopic direction of the telescopic mechanism.

[0187] In one embodiment, the carriage supports and secures the telescopic mechanism, which extends outside the carriage to retrieve depleted batteries removed from the electric vehicle and place them in the battery compartment for charging, and to retrieve fully charged batteries from the battery compartment for installation in the electric vehicle. Considering that electric vehicles requiring battery replacement may be misaligned when parked, the telescopic mechanism can be moved perpendicular to the telescopic direction based on the parked position of the electric vehicle to align the battery packs. Furthermore, the position of the telescopic mechanism can be adjusted to accommodate battery packs located at different locations within the battery compartment, allowing for access to and placement of batteries from different locations within the compartment.

The telescopic mechanism is provided with a fixed portion that moves perpendicular to the telescopic direction between the sliding mechanism and the body, thereby driving the entire telescopic mechanism to move relative to the body in a direction perpendicular to the telescopic direction. A telescopic portion is provided above the fixed portion, which can extend outside the body to access and place batteries.

[0226] In order to more clearly illustrate the overall concept of the present application, a detailed description is given below in an illustrative manner in conjunction with the accompanying drawings.

[0227] The following description sets forth many specific details to facilitate a thorough understanding of the present application. However, the present application may also be implemented in other ways than those described herein, and therefore, the scope of protection of the present application is not limited by the specific embodiments disclosed below. It should be noted that the embodiments of the present application and the features of each embodiment may be combined with each other unless there is a conflict.

They are only for the convenience of describing the present application and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, be constructed and operated in a specific orientation. Therefore, they cannot be understood as limitations on the present application.

[0229] In this application, unless otherwise expressly specified or limited, terms such as "installed," "connected," "connect," and "fixed" should be understood in a broad sense. For example, they may refer to fixed connection, detachable connection, or integration; mechanical connection, electrical connection, or communication; direct connection or indirect connection through an intermediate medium; and internal communication between two components or interaction between two components. Those skilled in the art will understand the specific meanings of the above terms in this application based on specific circumstances.

[0230] In this application, unless otherwise expressly specified and limited, a first feature "above" or "below" a second feature may be that the first and second features are in direct contact, or the first and second features are in indirect contact through an intermediate medium. In the description of this specification, the description with reference to the terms "one embodiment", "some embodiments", "example", "specific example", or "some examples" means that the specific features, structures, materials or characteristics described in conjunction with the embodiment or example are included in at least one embodiment or example of the present application. In this specification, the schematic representation of the above terms does not necessarily refer to the same embodiment or example. Moreover, the specific features, structures, materials or characteristics described may be combined in an appropriate manner in any one or more embodiments or examples.

[0231] Example 1:

[0232] As shown in Figures 1 to 5, the battery exchange equipment 1 includes a fixed support frame 11, a battery exchange body 12 arranged between the support frames 11 and capable of being raised and lowered, and a battery exchange device 13 arranged in the battery exchange body 12 and capable of being telescopically moved to the outside of the support frame 11. The battery disassembly and assembly operations of the battery exchange vehicle and / or the battery transfer operations between the battery compartment positions of the battery rack are realized through the telescopic movement of the battery exchange device 13 and the lifting and lowering movement of the battery exchange body 12.

[0233] The battery exchange body 12 can be raised and lowered on the support frame 11 to adjust the height of the battery exchange device 13. When the battery needs to be removed and installed, it is adjusted to the height corresponding to the car chassis and then extended. When a low-charged battery needs to be placed in the battery compartment for charging or a fully charged battery needs to be taken out of the battery compartment, it is adjusted to the height corresponding to the battery compartment and then extended to take and place the battery, thereby realizing battery disassembly and assembly operations on the battery exchange vehicle and / or battery transfer operations between battery compartment positions of the battery rack.

[0234] Furthermore, the battery-swapping device 13 includes a battery-swapping device 13 and a battery-swapping mechanism 132 disposed on the top surface of the battery-swapping device 13 . The battery-swapping mechanism 132 is driven by the battery-swapping device 13 to extend into the bottom of the battery-swapping vehicle to replace the battery pack.

[0235] By setting up the battery swap device 13, the telescopic function of the battery swap device 13 is realized. During battery swapping, the battery swap device 13 drives the battery swap mechanism 132 to extend into the bottom of the battery swap vehicle to swap the battery pack, thereby realizing battery disassembly and assembly operations on the battery swap vehicle and / or battery transfer operations between battery compartments of the battery rack.

[0236] Furthermore, the battery swap mechanism 132 includes a floating battery tray 1321 and an unlocking pin 1322 provided on the battery tray 1321. The battery tray 1321 extends into the bottom of the battery swap vehicle through the telescopic movement of the battery swap device 13. The unlocking pin 1322 unlocks or locks the battery pack as the battery tray 1321 rises and falls and the battery swap device 13 telescopes. The battery tray 1321 is used to support the battery pack during the battery swap process. As the battery swap device 13 telescopes, the battery tray 1321 extends into the bottom of the battery swap vehicle. Since the battery tray 1321 is a floating design, the floating characteristics of the battery tray 1321 allow it to adapt to the shape and state of different battery swap vehicle chassis, maintaining contact with the bottom of the vehicle, thereby achieving stable support for the battery pack. The unlocking pin 1322 abuts against the unlocking point of the battery pack as the battery tray 1321 rises and falls and the battery swap device 13 telescopes, thereby unlocking or locking the battery pack, improving the accuracy and efficiency of battery pack disassembly and assembly.

[0237] Furthermore, the battery exchange mechanism 132 also includes a bracket 1323, and the battery tray 1321 is arranged higher than the bracket 1323. The bracket 1323 is provided with an elastic member 1324 for making the battery tray 1321 floatable. The bracket 1323 can support the battery tray 1321 and improve the stability of the battery tray 1321. The elastic member 1324 on the bracket 1323 makes the battery tray 1321 have a floating characteristic, which allows the battery tray 1321 to adapt to the shape and state of different battery exchange vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving the stability and safety during the battery exchange process. In addition, the elastic member 1324 can enable the battery tray 1321 to adapt to different surfaces and pressures when contacting the bottom of the battery exchange vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery exchange, but also ensures the simplicity of battery exchange operation and the safe replacement of battery packs.

[0238] In one example, the battery exchange mechanism 132 further includes a bracket 1323 and a support plate 1326 disposed on the bracket 1323 , a sinking groove 13261 is formed on the support plate 1326 , and the battery tray 1321 is disposed in the sinking groove 13261 .

[0239] The battery tray 1321 is placed in the sunken groove 13261 on the support plate 1326, which reduces the overall height of the battery tray 1321 on the bracket 1323, making the overall thickness of the battery exchange mechanism 132 smaller and increasing the battery exchange space. In addition, the battery tray 1321 is placed in the sunken groove 13261 on the support plate 1326, which can ensure the stable position of the battery tray 1321 during the battery exchange process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery exchange.

[0240] As an embodiment of the present application, at least two battery positioning pins 13211 are further provided on the battery tray 1321; the battery positioning pins 13211 are distributed in the middle area of ​​the battery tray 1321 along the length direction of the battery tray 1321. The positioning pins provided on the battery tray 1321 can ensure the correct position of the battery pack during the battery replacement process, prevent displacement during movement or battery replacement, thereby improving the accuracy and safety of battery replacement. In addition, through the cooperation between the battery positioning pins 13211 and the battery pack, a positioning and clamping effect is generated on the battery pack, so as to facilitate the synchronous movement of the battery pack, and also enable the battery pack to better withstand the unlocking force, thereby improving the stability of the battery unlocking.

[0241] Furthermore, the battery exchange body 12 includes a compartment 121 and a movable component 122 arranged between the support frame 11 and capable of being raised and lowered and moved along the support frame 11. The battery exchange device 13 is arranged in the compartment 121, and the compartment 121 can be rotatably connected to the movable component 122 to adjust the direction of the battery exchange device 13.

[0242] By setting up a moving assembly 122 to drive the body 121 to move up and down along the support frame 11, the height of the battery-swapping device 13 can be adjusted. At the same time, the body 121 and the moving assembly 122 are rotatably connected, which facilitates the adjustment of the angle of the body 121, thereby adjusting the extension angle of the battery-swapping device 13. When the battery-swapping electric vehicle is parked at a deflection angle, it can be accurately positioned and extended to achieve precise battery swapping.

[0243] In one example, the support frame 11 includes a plurality of columns 111 formed on the outer peripheral side of the body 121, the moving assembly 122 includes at least two moving parts 1221 that are attached to the side walls of two adjacent columns 111 and can be raised and lowered, and a linkage part 1222 connected between the at least two moving parts 1221, and the body 121 can be rotatably connected to the bottom surface of the linkage part 1222.

[0244] By providing a plurality of columns 111 on the outer periphery of the body 121, the columns 111 cooperate with the movable assembly 122 to enable the movable assembly 122 to drive the body 121 up and down, thereby adjusting the height at which the battery exchange device 13 is extended. By providing a movable portion 1221 in the movable assembly 122 to cooperate with the columns 111 to achieve the lifting function, and by providing a linkage portion 1222 to be rotatably connected to the body 121, the body 121 is positioned and supported.

[0245] As an embodiment of the present application, the linkage part 1222 includes at least two cross beams 12221 whose two ends are respectively connected to the corresponding moving parts 1221 and at least two longitudinal beams 12222 connected between the at least two cross beams 12221, and the bottom surfaces of the at least two longitudinal beams 12222 are formed with installation surfaces for installing the car body 121.

[0246] The linkage part 1222 is provided with at least two cross beams 12221 for connecting with the moving parts 1221 on both sides. At least two longitudinal beams 12222 are provided to form an installation surface for installing the compartment 121. At the same time, the longitudinal beams 12222 also strengthen the overall structural strength of the linkage part 1222 to prevent deformation.

[0247] Furthermore, the battery transporter also includes a rotating mechanism 14 disposed between the body 121 and the linkage portion 1222. The rotating mechanism 14 includes a slewing bearing assembly 141 disposed between the mounting surface and the body 121, and a driving assembly 142 for rotating the slewing bearing assembly 141. The rotatable connection between the body 121 and the linkage portion 1222 is achieved via the rotating mechanism 14.

[0248] One embodiment: The rotating mechanism 14 uses a slewing support assembly 141 and a driving assembly 142 . The driving assembly 142 is used to drive the slewing support assembly to rotate, thereby driving the car body 121 to rotate.

[0249] In one example, the drive assembly 142 includes a rotating shaft 1421 extending through the mounting surface, a gear 1422 disposed on the rotating shaft 1421 and meshing with the slewing support assembly, and a rotating motor 1423 disposed on the top surface of the mounting plate and configured to rotate the rotating shaft 1421. Furthermore, the operating principle for achieving rotation between the carriage 121 and the mounting plate is as follows: the drive assembly 142 includes the rotating motor 1423 and the rotating shaft 1421, the rotating shaft 1421 being provided with a gear 1422, which meshes with the slewing support assembly. The motor drives the gear 1422 to rotate, thereby driving the slewing support assembly to rotate, thereby driving the carriage 121 to rotate.

[0250] As an implementation mode of an embodiment of the present application, the linkage portion 1222 also includes a first reinforcement portion 12223 arranged at least corresponding to the mounting surface, the first reinforcement structure includes a plurality of reinforcement plates 122231, the two ends of the reinforcement plate 122231 are respectively fixedly connected to the longitudinal beams 12222 at the two ends, the bottom of the reinforcement plate 122231 is fixedly connected to the mounting plate, and / or, the first reinforcement structure includes a plurality of reinforcement plates 122231 arranged between the longitudinal beams 12222, and a transition connection plate 122232 is also provided on the beam surface at the connection between the reinforcement plate 122231 and the longitudinal beam 12222.

[0251] Since the compartment 121 includes a battery exchange device 13, batteries will be placed on the battery exchange device 13 during use, and the weight is supported only by the linkage part 1222. The structural strength of the linkage part 1222 is strengthened by providing a first reinforcement part 12223 to prevent deformation.

[0252] In one embodiment, the first reinforcement structure includes a plurality of reinforcement plates 122231, which are fixedly connected to the longitudinal beams 12222 and the mounting plate to enhance the structural strength of the entire linkage portion 1222. To further enhance the structural strength of the linkage portion 1222, a transition connecting plate 122232 may be provided on the beam surface where the reinforcement plates 122231 connect to the longitudinal beams 12222.

[0253] In one example, the moving portion 1221 includes a connecting rod 12211 and a vertically arranged fixed plate 12212 fixed at both ends of the connecting rod 12211. At least two sliders 152 are sequentially provided on the side wall of each column 111 and one of the fixed plates 12212 along the lifting and moving direction, and a slide rail 1112 that cooperates with the slider 152 is provided on the side wall of the other column. The fixed plate 12212 and the column 111 are slidably connected through the structural cooperation of the slider 152 and the slide rail 1112. As for whether the slider 152 and the slide rail 1112 are specifically arranged on the fixed plate 12212 or the column 111, there is no limitation. Both arrangements can achieve the technical effect of lifting and lowering. At least two sliders 152 are sequentially provided along the lifting and lowering direction to limit the running track of the sliding mechanism 124, prevent deviation during lifting and lowering, and improve stability.

[0254] In another example, at least two rollers 122121 are provided on two perpendicular side walls of the fixing plate 12212 adjacent to the column 111, and rolling surfaces 1113 that cooperate with the rollers 122121 are provided on two mutually perpendicular side walls corresponding to the column 111. Another lifting and lowering cooperation structure uses the cooperation between the rollers 122121 and the rolling surfaces 1113 to achieve the lifting and lowering of the battery exchange body 12.

[0255] Furthermore, the battery-exchanging body 12 also includes a compartment 121 , and a sliding mechanism 124 is provided between the battery-exchanging device 13 and the compartment 121 so that the battery-exchanging device 13 can move relative to the compartment 121 in a direction perpendicular to the telescopic direction.

[0256] The compartment 121 is used to support and fix the battery-changing device 13. The battery-changing device 13 is used to extend out of the compartment 121 to take out the low-charged battery removed from the tram and put it into the battery compartment for charging, and to take out the fully charged battery in the battery compartment for easy installation on the tram. Taking into account that the tram that needs battery replacement may have position deviation when parked, a sliding mechanism 124 is set between the battery-changing device 13 and the compartment 121. The battery-changing device 13 can be moved in a direction perpendicular to the extension direction according to the parking position of the tram, so as to align with the battery pack of the tram; on the other hand, the position of the battery-changing device 13 can be adjusted for battery packs at different positions in the battery compartment, and batteries at different positions in the battery compartment can be taken and placed.

[0257] In one example, the sliding mechanism 124 includes a fixed part 1241 arranged in the compartment 121 along a direction perpendicular to the telescopic direction and a movable part 1242 movably arranged on the fixed part 1241. The battery exchange device 13 includes a fixed part 1311 connected to the fixed part 1241 or the movable part 1242 and a telescopic part 1312 movably connected to the fixed part 1311.

[0258] By providing a fixing part 1241 and a moving part 1242 in the sliding mechanism 124, the two structures cooperate to realize the function of the battery exchange device 13 moving relative to the body 121 in a direction perpendicular to the telescopic direction. A fixing part 1311 is provided in the battery exchange device 13, and the fixing part 1311 moves between the sliding mechanism 124 and the body 121 in a direction perpendicular to the telescopic direction, thereby driving the entire battery exchange device 13 to move relative to the body 121 in a direction perpendicular to the telescopic direction. A telescopic part 1312 is provided on the fixing part 1311, and the telescopic part 1312 can be extended out of the body 121 to take and place the battery, and the telescopic movement function of the battery exchange device 13 is realized by the movably connection between the telescopic part 1312 and the fixed part 1311.

[0259] As an embodiment of the present application, the battery exchange equipment 1 also includes a guide mechanism 15 arranged between the body 121 and the battery exchange device 13, the guide mechanism 15 includes a guide rail 151 and a slider 152 arranged in pairs, one of the guide rail 151 and the slider 152 is fixed to the body 121, and the other is fixed to the battery exchange device 13.

[0260] The guide mechanism 15 is used to play a role of limiting and guiding the movement of the battery exchange device 13 relative to the body 121 in a direction perpendicular to the telescopic direction. A pair of matching guide rails 151 and sliders 152 are provided in the guide mechanism 15. By fixing the slider 152 to any one of the body 121 and the battery exchange device 13, and fixing the other to the guide rail 151, a sliding fit between the guide rail 151 and the slider 152 is achieved, so that the battery exchange device 13 can be limited and guided when it moves relative to the body 121 in a direction perpendicular to the telescopic direction.

[0261] In one embodiment, the fixed member 1241 is a rack of a preset length, the movable member 1242 is a gear 1422, the gear 1422 is provided on the battery exchange device 13, the rack is provided on the body 121, and the sliding mechanism 124 further includes a drive motor 1243 provided on the battery exchange device 13 for driving the gear 1422 to rotate. By specifically setting the fixed member 1241 as a rack of a preset length, and setting the movable member 1242 as a gear 1422 that cooperates with the rack, the rack is fixed on the body 121, the gear 1422 is fixed on the battery exchange device 13, and the gear 1422 and the rack are meshed. By providing a drive motor 1243 on the battery exchange device 13 to drive the gear 1422 to rotate, the gear 1422 generates an interaction force with the rack while rotating. Since the rack is fixed, the gear 1422 drives the battery exchange device 13 to move relative to the body 121 in a direction perpendicular to the telescopic direction.

[0262] Furthermore, the drive motor 1243 is connected to the adjacent fixed part 1311 through a fixed mounting plate 12431. A mounting hole is provided on the fixed mounting plate 12431, and the rotating shaft 1421 of the drive motor 1243 passes through the mounting hole and is connected to the gear 1422; the bottom of the frame of the compartment 121 includes a beam 12221 arranged in a direction perpendicular to the telescopic direction of the battery exchange device 13, and the rack is fixedly connected to the beam 12221. The extension direction of the rack is perpendicular to the telescopic direction of the battery exchange device 13. The gear 1422 is driven to rotate by the drive motor 1243 to move relative to the rack, thereby driving the battery exchange device 13 to move synchronously.

[0263] The driving motor 1243 is fixedly connected to the fixed part 1311 in the battery exchange device 13 through the fixed mounting plate 12431, and a mounting hole is opened on the fixed mounting plate 12431 to facilitate the fixed connection between the output shaft of the driving motor 1243 and the gear 1422 to drive the gear 1422 to rotate; considering that the moving direction of the battery exchange device 13 is perpendicular to the telescopic direction, the rack is fixed on the beam 12221 perpendicular to the telescopic direction of the battery exchange device 13, and the extension direction of the rack is perpendicular to the telescopic direction of the battery exchange device 13. When the gear 1422 rotates, it can only move in a direction perpendicular to the telescopic direction, thereby driving the battery exchange device 13 to move in a direction perpendicular to the telescopic direction.

[0264] Furthermore, both ends of the fixing portion 1311 are slidably connected to the crossbeam 12221 through the guide mechanism 15, and the two ends of the fixing portion 1311 are located above the crossbeam 12221. The lower part of the fixing portion 1311 includes a downwardly protruding limit base 13111, and the two ends of the limit base 13111 are clamped between the two crossbeams 12221.

[0265] The battery exchange device 13 is moved in a direction perpendicular to the extension direction through the sliding connection between the fixed part 1311 and the crossbeam 12221. In order to realize the above movement function and limit the movement trajectory of the battery exchange device 13, a guide mechanism 15 and a limit base 13111 are provided. The guide mechanism 15 includes a slider 152 and a guide rail 151 to realize the sliding connection between the fixed part 1311 and the battery exchange device 13. The guide rail 151 also limits the movement trajectory of the fixed part 1311, and it can only move along the length direction of the guide rail 151. In order to further stabilize the movement trajectory of the battery exchange device 13, a downwardly protruding limit base 13111 is provided on the fixed part 1311, and the two ends of the limit base 13111 are clamped between the two crossbeams 12221 to ensure that the battery exchange device 13 can only move in a direction perpendicular to the extension direction to prevent angle deviation and affect the accuracy of battery removal and placement.

[0266] In one example, both beams 12221 are provided with a positioning groove 12111 facing the fixing portion 1311 , the guide rail 151 is at least partially located in the positioning groove 12111 , the slider 152 is fixedly connected to the fixing portion 1311 , and the slider 152 is slidably engaged with the guide rail 151 .

[0267] By providing a positioning groove 12111 on the crossbeam 12221 for fixing the guide mechanism 15, the trajectory of relative movement between the battery exchange device 13 and the body 121 is defined. Placing part or all of the guide rail 151 in the guide mechanism 15 in the positioning groove 12111 can effectively reduce the thickness of the body 121 and the battery exchange device 13 as a whole while improving the strength of the body 121. By sliding the slider 152 fixed on the fixing portion 1311 in cooperation with the guide rail 151, the battery exchange device 13 can be moved in a direction perpendicular to the telescopic direction.

[0268] In one embodiment, the guide rail 151 and the slider 152 are both contained in the positioning groove 12111 , which limits the slider 152 and prevents it from detaching from the guide rail 151 .

[0269] Furthermore, the battery exchange device 1 also includes two independent lifting drive mechanisms 16 respectively arranged on both sides of the battery exchange body 12. The lifting drive mechanism 16 includes a lifting motor 161. The support frame 11 includes a plurality of columns 111 arranged around the battery exchange body 12. Each column 111 is provided with a vertically movable counterweight block 162. The counterweight block 162 is connected to the fixed plate 12212 on the corresponding side through a chain 163. A sprocket 164 is provided above each column 111 to cooperate with the side chain 163 for transmission. The lifting motor 161 drives the synchronous shaft to rotate, thereby simultaneously driving the two chains 163 located on the same side of the battery exchange body 12 to drive the moving part 1221 to move vertically.

[0270] Two independent lifting drive mechanisms 16 are set to independently control the lifting height on both sides of the battery-exchanging body 12, so that the battery-exchanging body 12 can be tilted. In actual operation, the chassis of the tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, the tilt angle of the protruding part of the battery-exchanging device 13 needs to be adjusted. By independently controlling the lifting height on both sides of the battery-exchanging body 12, the purpose of tilting the car body 121 is achieved. When the car body 121 is tilted, the battery-exchanging device 13 in the car body 121 is at the same tilt angle as the car body 121, and the protruding part can be well attached to the tram chassis for battery disassembly and transportation.

[0271] In one embodiment, the lifting drive mechanism 16 includes a motor. This motor drives the synchronous shaft to rotate, thereby simultaneously driving two chains 163 on the same side of the battery swap unit 12, which in turn drive the sliding mechanism 124 to move vertically. This controls the height and tilt angle of the battery swap unit 13, allowing precise battery swapping operations to be performed in close contact with the vehicle chassis. By providing a counterweight 162, chain 163, and sprocket 164 on each column 111 and connecting them to the sliding mechanism 124 on the corresponding side, synchronous lifting and lowering of the battery swap unit 12 on the same side is achieved.

[0272] Furthermore, the counterweight block 162 is located on the end side adjacent to or on the opposite side of the battery swap body 12. The counterweight block 162 has two settings: one is to be set on the end side adjacent to the battery swap body 12 to facilitate battery transportation between battery compartments; the other is to be set on the other side opposite to the battery swap body 12 to optimize the space utilization efficiency of the battery swap station 2.

[0273] Furthermore, the battery exchange body 12 includes a compartment 121 and a movable component 122 arranged between the support frames 11 and capable of being raised and lowered along the support frames 11. The movable component 122 includes at least two movable parts 1221 arranged in contact with the side walls of two adjacent columns 111 and capable of being raised and lowered, and a linkage part 1222 connected between the at least two movable parts 1221. A rotating shaft 1421 is provided on the end face of one of the linkage part 1222 and the movable part 1221, and a through hole 12214 or a waist-shaped hole is provided on the end face of the other end face, thereby realizing a rotational connection or movable connection between the battery exchange body 12 and the movable component 122.

[0274] Through the cooperation between the support frame 11 and the moving component 122, the moving component 122 drives the compartment 121 to rise and fall, thereby adjusting the height of the battery exchange device 13. The lifting function is achieved by setting a moving part 1221 in the moving component 122 to cooperate with the support frame 11, and the positioning and supporting function of the compartment 121 is achieved by setting the linkage part 1222. Specifically, the battery exchange body 12 is tilted by the rotation cooperation of the rotating shaft 1421 and the through hole 12214, and the movement cooperation of the rotating shaft 1421 and the waist-shaped hole, thereby achieving the tilt of the battery exchange device 13. As for whether the rotating shaft 1421, the through hole 12214, and the waist-shaped hole are specifically set in the battery exchange body 12 or the sliding mechanism 124, there is no specific limitation, and the effect of this technology can be achieved.

[0275] In one example, the linkage portion 1222 includes two crossbeams 122211211, each of which is disposed at its ends corresponding to the column 111. The movable portion 1221 includes at least two sliders 1521, each of which is fitted on the sidewalls of the column 111, and a connecting rod 12211 connecting the sliders 152 on both sides. The linkage portion 1222 is connected to the movable portion 1221 by providing the crossbeams 12221 corresponding to the column 111. The movable portion 1221 is connected to the column 111 via the sliders 152. The connecting rod 12211 is provided to connect the two sliders 152 on the same side for synchronous movement, thereby achieving synchronous lifting and lowering of the same side of the carriage 121.

[0276] Furthermore, a rotating shaft 1421 is provided through the side walls of the crossbeam 12221 near both ends, and a shaft sleeve is fixed inside the crossbeam 12221 to install the rotating shaft 1421; a U-shaped lug 122111 is provided on the side wall of the connecting rod 12211 facing the battery exchange body 12, and a through hole 12214 or a waist-shaped hole is provided on the lug side wall of the U-shaped lug 122111.

[0277] A rotating shaft 1421 and a sleeve for mounting the rotating shaft 1421 are provided on the crossbeam 12221, which are rotatably matched with the through hole 12214 on the connecting rod 12211 and are slidably connected with the waist-shaped hole, so as to realize the tilting of the car body 121 and the internal battery exchange device 13. In this embodiment, a U-shaped lug 122111 is specifically provided on the connecting rod 12211, and the through hole 12214 and the waist-shaped hole are provided on the U-shaped lug 122111 to realize the connection between the crossbeam 12221 and the connecting rod 12211. In an actual working environment, the chassis of the tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, the tilt angle of the protruding part of the battery exchange device 13 needs to be adjusted. By rotatably connecting one end of the crossbeam 12221 to the corresponding connecting rod 12211 and movably connecting the other end to the corresponding connecting rod 12211, the two sides of the car body 121 can be raised to different heights, thereby achieving the purpose of tilting the car body 121. When the car body 121 is tilted, the battery exchange device 13 in the car body 121 is at the same tilt angle as the car body 121, and the protruding part can be well attached to the tram chassis for disassembly and transportation of the battery.

[0278] In one embodiment, a U-shaped lug 122111 is provided on the side wall near both ends of the connecting rod 12211, and a rotating shaft 1421 is provided through the U-shaped lug 122111. Connectors that match the spacing between the two sliding mechanisms 124 are provided at both ends of the crossbeam 12221. The connectors are provided with through holes 12214 or movable grooves. The through holes 12214 are circular holes that pass through the connectors and match the rotating shaft 1421. The movable grooves are waist-shaped holes that extend along the length of the crossbeam 12221 and pass through the connectors. In this embodiment, specifically, a connector is provided on the crossbeam 12221, the through holes 12214 and the waist-shaped holes are provided on the connectors, and the rotating shaft 1421 is provided on the connecting rod 12211, which can also achieve the tilting of the compartment 121 and the internal battery exchange device 13.

[0279] Furthermore, the present application also provides a battery swap station 2, comprising the above-mentioned battery swap equipment 1, battery swap platform 21 and battery storage device 22; the battery swap equipment 1 is arranged on at least one side of the battery swap platform 21 along the driving direction of the battery swap vehicle; the battery storage device 22 at least includes a first battery storage device 221 arranged on at least one side of the battery swap equipment 1 in a direction parallel to the driving direction of the battery swap vehicle, the first battery storage device 221 includes a first battery rack 2211 arranged with an opening toward the battery swap equipment 1, and the first battery rack 2211 is vertically arranged with multiple first battery compartments 22111 in sequence; the first battery rack 2211 and the support frame 11 reuse the column 111; or, the first battery rack 2211 and the support frame 11 are independent of each other.

[0280] In one embodiment, the battery exchange device 1 can be arranged on one side or both sides of the battery exchange platform 21 along the driving direction of the battery exchange vehicle, so that single-sided and / or double-sided battery exchange can be achieved, thereby improving the battery exchange efficiency; the battery exchange mechanism 132 in the battery exchange device 1 can be steered to make the arrangement of the above-mentioned battery storage device 22 more flexible and more scalable, and the above-mentioned first battery rack 2211 can be arranged around the circumference of the battery exchange device 1, thereby improving space utilization and increasing battery storage capacity; the first battery rack 2211 and the support frame 11 reuse the column 111 to shorten the battery transfer distance between the first battery rack 2211 and the battery exchange device 1, thereby further improving the battery exchange efficiency, and at the same time it can also simplify the equipment structure, save installation space and equipment costs.

[0281] Furthermore, the battery storage device 22 also includes a second battery storage device 222 arranged on the side of the battery swap device 1 opposite to the battery swap platform 21. The second battery storage device 222 includes at least one row of second battery racks 2221 arranged toward the battery swap device 1. The second battery rack 2221 is vertically arranged with a plurality of second battery compartments 22211 in sequence.

[0282] The second battery storage device 222 also includes a third battery rack 2222 arranged on at least one side of the second battery rack 2221 in a direction parallel to the driving direction of the battery-swap vehicle. The third battery rack 2222 has at least one third battery compartment 22221 in any horizontal direction. A battery conveying mechanism is arranged between the third battery compartment 22221 and the second battery compartment 22211 at the same vertical height. The battery conveying mechanism can transfer battery packs between the second battery compartment 22211 and the third battery compartment 22221.

[0283] In the above scheme, the setting of the second battery rack 2221 and the third battery rack 2222 can further utilize the installation space around the battery exchange equipment 1, and the setting of the battery conveying mechanism can transport the fully charged batteries to a location closer to the battery exchange equipment 1 for easy access, and the low-charged batteries are transported to a location farther away from the battery exchange equipment 1 for charging and standby use. This makes the management and allocation of fully charged batteries and low-charged batteries in the entire battery exchange station 2 more reasonable, which is conducive to further improving the battery exchange efficiency.

[0284] As an embodiment of the present application, the first battery rack 2211 and the support frame 11 are independent of each other, and the support frame 11 can rotate relative to the battery storage device 22 .

[0285] In the above scheme, the support frame 11 and the first battery rack 2211 are independent of each other, which makes it convenient for the support frame 11 to drive the body 121 to rotate as a whole, so that the extension mechanism and the battery replacement mechanism 132 can achieve 360° operation, which makes the setting method of the first battery rack 2211 more flexible.

[0286] When the opening faces the battery compartment opening, the column 111 is positioned outside the horizontal projection of the opening and / or the compartment opening. This arrangement further prevents the column 111 from interfering with the rotation of the compartment 121 and the extension mechanism / battery swapping mechanism 132 outside the compartment 121, thereby ensuring smooth battery swapping.

[0287] As an embodiment of the present application, the first battery rack 2211 is arranged on both sides of the battery swapping device 1 along a direction parallel to the driving direction of the battery swapping vehicle; the first battery rack 2211 is fixedly arranged, and the second battery rack 2221 and the third battery rack 2222 can be moved relative to the battery swapping device 1 along a direction parallel to the driving direction of the battery swapping vehicle.

[0288] In the above scheme, the first battery rack 2211 and the second battery rack 2221 are arranged at a 90° angle on the side of the battery exchange device 1. This arrangement makes the single rotation angle of the compartment 121 fixed, which makes it more convenient to control the rotation of the compartment 121; the second battery rack 2221 and the third battery rack 2222 can move relative to the battery exchange device 1. When the second battery rack 2221 is fully loaded, the second battery rack 2221 can be moved away, and the third battery rack 2222 can be moved to the position of the original second battery rack 2221 for standby use, which is beneficial to improving the overall utilization efficiency of the battery storage device 22. Of course, the relative angle between the first battery rack 2211 and the second battery rack 2221 can also be adjusted, so that the first battery rack 2211, the second battery rack 2221 and the battery exchange platform 21 can be arranged in a pentagon, hexagon or other different arrangements on the side of the battery exchange device 1.

[0289] Furthermore, the battery compartment includes a support beam 221111 for supporting the battery pack, the support beam 221111 is located in the top area of ​​the battery compartment, and the battery pack is suspended and fixed on the support beam 221111; or, the support beam 221111 is located in the bottom area of ​​the battery compartment, and the battery pack is supported and placed on the support beam 221111.

[0290] The battery pack is fixed in a suspended manner on the support beam 221111. This fixing method is the same as the fixing method of the battery pack on the chassis of the battery swap vehicle. This design can facilitate the replacement and maintenance of the battery pack, and can also effectively utilize the space in the battery compartment; the battery pack is supported and placed on the support beam 221111 in the bottom area of ​​the battery compartment. This layout helps to stabilize the battery pack and simplify the loading and unloading process of the battery, thereby improving the convenience and safety of storing and retrieving the battery pack.

[0291] When the support beam 221111 is located in the top area of ​​the battery compartment, a battery locking mechanism 221112 is provided on the support beam 221111; the unlocking pin 1322 unlocks or locks the battery locking mechanism 221112 as the battery tray 1321 rises and falls and the battery exchange device 13 extends and contracts.

[0292] The battery locking mechanism 221112 can not only fix the battery pack, but its unlocking and locking principles are the same as the unlocking and locking principles of the battery pack on the battery swap vehicle. Therefore, it improves the versatility of the battery swap mechanism 132 in storing and retrieving batteries in the battery compartment and disassembling and installing batteries at the bottom of the battery swap vehicle, greatly improving the battery swap efficiency.

[0293] Furthermore, an electrical connection device 22112 is provided on the battery rack, and the interface end of the electrical connection device 22112 corresponds to the compartment opening of the battery compartment; the battery locking mechanism 221112 is suitable for fixing the battery pack, and when the battery pack is moved to be locked with the battery locking mechanism 221112, the charging port of the battery pack is electrically connected to the interface end of the electrical connection device 22112.

[0294] The electrical connection device 22112 can charge the battery pack placed on the battery compartment. Furthermore, after the battery locking mechanism 221112 fixes the battery pack, the interface end of the battery pack can be docked with the electrical connection device 22112. This design ensures that the battery pack can be safely charged in a locked state, and is also convenient for management and maintenance.

[0295] The present application also provides a battery swap method, which is applied to the above-mentioned battery swap station 2 and includes the following steps:

[0296] Step 1: Before the battery swap vehicle enters the battery swap platform 21 and / or after it parks on the battery swap platform 21, obtain the vehicle model information; after the battery swap vehicle parks in place, obtain the position information of the battery swap vehicle along the length direction of the vehicle body;

[0297] Step 2: Based on the vehicle model information, control the movement of the compartment 121 relative to the support frame 11 so that the battery swap mechanism 132 corresponds to the battery pack installation area of ​​the battery swap vehicle or the fully charged battery compartment on the battery rack in the vertical direction;

[0298] Step 3: Based on the vehicle model information and position information, the sliding mechanism 124 is controlled to move so that the battery swap mechanism 132 on the battery swap device 13 moves relative to the compartment 121 along the vehicle body direction and the battery swap mechanism 132 corresponds to the battery pack installation area of ​​the battery swap vehicle along the vehicle body direction;

[0299] Step 4: Based on the vehicle model information and location information, the battery swap device 13 is controlled to move so that the battery swap device 13 drives the battery swap mechanism 132 to extend toward the battery swap vehicle to below the battery pack installation area and the battery swap mechanism 132 is controlled to move to remove the low-charged battery from the battery swap vehicle; alternatively, the battery swap device 13 is controlled to move so that the battery swap device 13 drives the battery swap mechanism 132 to extend toward the battery rack and the battery swap mechanism 132 is controlled to move to remove the fully charged battery from the fully charged battery compartment;

[0300] Based on the vehicle model information and location information, the battery swap device 13 is controlled to drive the battery swap mechanism 132 to extend toward the battery rack and the battery swap mechanism 132 is controlled to place the low-charged battery on the battery rack; or, the battery swap device 13 is controlled to drive the battery swap mechanism 132 to extend toward the battery swap vehicle to the bottom of the battery pack installation area and the battery swap mechanism 132 is controlled to install the fully charged battery on the battery swap vehicle.

[0301] In the above scheme, before the battery-swapping vehicle enters the battery-swapping platform 21 and / or after it parks on the battery-swapping platform 21, the vehicle model information of the battery-swapping vehicle is obtained, so that the fully charged battery of the corresponding model can be pre-fetched according to the vehicle model information before the battery-swapping operation is performed. The time before and after the battery-swapping vehicle is parked and during the waiting period for battery-swapping can be fully utilized to improve the battery-swapping efficiency and bring a better battery-swapping experience to users. At the same time, the above-mentioned battery-swapping steps can be adopted to align the battery pack of the battery-swapping vehicle according to the vehicle information and vehicle position information of the battery-swapping vehicle. The battery-swapping steps in the entire battery-swapping process are simple and efficient, and the above-mentioned battery-swapping steps enable the battery-swapping station 2 to realize single-sided / double-sided battery-swapping, and can also adapt to the battery-swapping needs of different models, with higher battery-swapping efficiency and greater versatility.

[0302] In one embodiment, step three includes:

[0303] s1, control the battery swap device 13 to drive the battery swap mechanism 132 to extend to a preset position toward the battery swap vehicle;

[0304] s2, controls the sliding mechanism 124 to move, so that the battery-changing device 13 drives the battery-changing mechanism 132 to move from the preset position along the direction of the vehicle body relative to the compartment 121 and makes the battery-changing mechanism 132 correspond to the battery pack installation area along the direction of the vehicle body.

[0305] The battery-swapping device 13 first drives the battery-swapping mechanism 132 to extend to a predetermined position, which can provide sufficient displacement space for the subsequent sliding mechanism 124 to drive the battery-swapping device 13 and the battery-swapping mechanism 132 to move along the direction of the vehicle body, thereby avoiding interference between the battery-swapping mechanism 132 and / or the battery-swapping device 13 and the compartment 121 during the movement along the direction of the vehicle body, and can ensure that the battery-swapping mechanism 132 accurately corresponds to the battery pack installation area of ​​the battery-swapping vehicle and can also ensure the safe operation of the equipment.

[0306] In one embodiment, step four includes:

[0311] e1, control the carriage 121 to move vertically relative to the support frame 11, control the sliding mechanism 124 to move the battery-swapping mechanism 132 relative to the carriage 121, so that the battery-swapping mechanism 132 corresponds to the empty battery compartment on the battery rack, control the battery-swapping device 13 to drive the battery-swapping mechanism 132 and the low-charge battery carried by the battery-swapping mechanism 132 to extend toward the battery rack, and control the battery-swapping mechanism 132 to place the low-charge battery in the empty battery compartment;

[0312] f1, control the battery swap device 13 to drive the battery swap mechanism 132 to retract into the compartment 121, and control the compartment 121 to move vertically relative to the support frame 11 so that the battery swap mechanism 132 corresponds to the fully charged battery compartment on the battery rack;

[0313] g1, control the battery swap device 13 to drive the battery swap mechanism 132 to extend toward the battery rack and control the battery swap mechanism 132 to take out the fully charged battery from the fully charged battery compartment;

[0314] h1, control the battery swap device 13 to drive the battery swap mechanism 132 and the battery swap mechanism 132 carrying the fully charged battery to retract into the compartment 121, and control the compartment 121 to rotate relative to the support frame 11 so that the battery swap mechanism 132 faces the battery swap vehicle;

[0315] i1, control the carriage 121 to move relative to the support frame 11 so that the battery swap mechanism 132 corresponds to the battery pack installation area in the vertical direction, and repeat steps s1-s2;

[0316] j1, control the battery swap device 13 to drive the battery swap mechanism 132 and the fully charged battery to extend below the battery pack installation area, and control the battery swap mechanism 132 to move the fully charged battery to facilitate installation in the battery pack installation area;

[0317] k1, control the battery exchange device 13 to drive the battery exchange mechanism 132 to retract into the compartment 121;

[0318] l1, repeat steps a1-k1.

[0319] In the above scheme, the overall working sequence of the battery exchange equipment 1 can be simply summarized as taking out the depleted battery - discharging the depleted battery - taking out the fully charged battery - installing the fully charged battery. This working sequence can adapt to the battery exchange needs of most vehicles, has strong versatility, and is combined with the battery storage device 22 arranged around the battery transfer device to greatly improve the battery exchange efficiency.

[0320] In another embodiment, the battery swap mechanism 132 includes a first battery swap mechanism 132 and a second battery swap mechanism 132 provided at both ends of the battery swap device 13 along the telescopic direction of the battery swap device 13; step four includes:

[0321] a2, based on the vehicle model information and location information, controls the battery swap device 13 to move so that the battery swap device 13 drives the first battery swap mechanism 132 to extend toward the fully charged battery compartment of the battery rack and controls the first battery swap mechanism 132 to move out of the fully charged battery compartment and carry the fully charged battery;

[0322] b2, control the battery exchange device 13 to drive the first battery exchange mechanism 132 and the fully charged battery to retract into the compartment 121;

[0323] c2, control the compartment 121 to move vertically relative to the support frame 11 and repeat steps s1-s2, so that the second battery exchange mechanism 132 corresponds to the battery pack installation area in the vertical direction and the direction of the vehicle body;

[0324] d2, control the battery swap device 13 to drive the second battery swap mechanism 132 to extend toward the battery swap vehicle to the battery pack installation area, control the second battery swap mechanism 132 to unlock and remove the low-charge battery installed in the battery pack installation area and carry the low-charge battery;

[0325] e2, control the battery exchange device 13 to drive the second battery exchange mechanism 132 and the low-power battery to retract into the compartment 121;

[0326] f2, control the car body 121 to rotate relative to the support frame 11 so that the first battery swap mechanism 132 and the fully charged battery face the battery swap vehicle;

[0327] g2, control the compartment 121 to move vertically relative to the support frame 11 and repeat steps s1-s2, so that the first battery exchange mechanism 132 corresponds to the battery pack installation area in the vertical direction and the direction of the vehicle body;

[0328] h2, control the battery swap device 13 to drive the first battery swap mechanism 132 and the fully charged battery to extend to the battery swap vehicle below the battery pack installation area, and control the first battery swap mechanism 132 to move the fully charged battery to facilitate installation in the battery pack installation area;

[0329] i2, control the battery exchange device 13 to drive the first battery exchange mechanism 132 to retract into the compartment 121;

[0330] j2, control the compartment 121 to move vertically relative to the support frame 11 so that the second battery-exchanging mechanism 132 corresponds to the empty battery compartment on the battery rack, control the battery-exchanging device 13 to drive the second battery-exchanging mechanism 132 and the low-power battery to extend toward the battery rack, and control the second battery-exchanging mechanism 132 to place the low-power battery in the empty battery compartment;

[0331] k2, control the battery exchange device 13 to drive the second battery exchange mechanism 132 to retract into the compartment 121;

[0332] l2, repeat steps a2-k2.

[0333] In the above scheme, the battery swapping device 1 immediately takes a suitable fully charged battery after obtaining the battery swapping vehicle information. After the battery swapping vehicle is parked in place, it directly performs the operation of removing the low-charged battery - retracting the low-charged battery - switching the position so that the fully charged battery is aligned with the battery swapping vehicle - installing the fully charged battery on the battery swapping vehicle - retracting and transferring the low-charged battery to the battery compartment, making full use of the parking time of the battery swapping vehicle, and performing the low-charged battery transfer operation after the battery swapping vehicle is fully charged for installation, which effectively shortens the overall battery swapping time and further improves the battery swapping efficiency.

[0334] As an embodiment of the present application, perpendicular to the vehicle body direction, the distance between the preset position and the compartment 121 is smaller than the distance between the battery-swap vehicle and the compartment 121.

[0335] Setting the above-mentioned preset position can provide sufficient displacement space for the subsequent sliding mechanism 124 to drive the battery swap device 13 and the battery swap mechanism 132 to move along the direction of the vehicle body, thereby avoiding the interference between the battery swap mechanism 132 and / or the battery swap device 13 and the compartment 121 during the movement along the direction of the vehicle body, and can ensure that the battery swap mechanism 132 and the battery pack installation area of ​​the battery swap vehicle are accurately aligned and the safe operation of the equipment; and the preset position is set between the battery swap vehicle and the compartment 121, which is also convenient for more intuitive monitoring of the relative position between the battery swap mechanism 132 and the battery swap vehicle, which is conducive to more accurate completion of the battery swap action.

[0336] As an embodiment of the present application, the position information includes the position in the length direction of the vehicle body, the position in the width direction of the vehicle body, and the position in the height direction of the vehicle body. In step four, the sliding mechanism 124 is controlled to move based on the position in the length direction of the vehicle body; in step four, the battery exchange device 13 is controlled based on the position in the width direction of the vehicle body to drive the battery exchange mechanism 132 to extend to the bottom of the battery pack installation area.

[0337] By collecting and identifying the above information, the actions of the battery exchange device 13, the sliding mechanism 124 and the battery exchange mechanism 132 in the above scheme can be controlled more accurately, thereby improving the efficiency and effectiveness of each action, thereby helping to improve the overall battery exchange efficiency.

[0338] Example 2:

[0339] As shown in Figures 6 to 11, a battery transport device 1 includes: a compartment 11 and a telescopic mechanism 12 arranged in the compartment 11 and capable of being telescopically moved outward. The battery transport device 1 also includes a sliding mechanism 13 arranged between the telescopic mechanism 12 and the compartment 11 to enable the telescopic mechanism 12 to move relative to the compartment 11 in a direction perpendicular to the telescopic direction.

[0340] The body 11 is used to support and secure the telescopic mechanism 12. The telescopic mechanism 12 is used to extend outside the body 11 to remove depleted batteries from the tram and place them in the battery compartment for charging, and to remove fully charged batteries from the battery compartment for installation on the tram. Considering that a tram requiring battery replacement may experience positional deviations when parked, a sliding mechanism 13 is provided between the telescopic mechanism 12 and the body 11. The telescopic mechanism 12 can be moved perpendicular to the telescopic direction according to the tram's parking position, thereby aligning the tram's battery pack. Furthermore, the position of the telescopic mechanism 12 can be adjusted to accommodate battery packs at different locations within the battery compartment, allowing for access to batteries at different locations within the compartment.

[0341] The sliding mechanism 13 includes a fixed part 131 arranged in the compartment 11 along a direction perpendicular to the telescopic direction and a movable part 132 movably arranged on the fixed part 131. The telescopic mechanism 12 includes a fixed part 121 connected to the fixed part 131 or the movable part 132 and a telescopic part 122 movably connected to the fixed part 121.

[0342] By providing a fixed member 131 and a movable member 132 within the sliding mechanism 13, the two structures cooperate to enable the telescopic mechanism 12 to move relative to the body 11 in a direction perpendicular to the telescopic direction. The telescopic mechanism 12 is provided with a fixed portion 121, which moves perpendicular to the telescopic direction between the sliding mechanism 13 and the body 11, thereby driving the entire telescopic mechanism 12 to move relative to the body 11 in a direction perpendicular to the telescopic direction. The fixed portion 121 is provided with a telescopic portion 122, which can extend outside the body 11 to remove and place batteries. The telescopic movement of the telescopic mechanism 12 is achieved through the movable connection between the telescopic portion 122 and the fixed portion 121.

[0343] The battery transport device 1 also includes a guide mechanism 14 arranged between the body 11 and the telescopic mechanism 12. The guide mechanism 14 includes a guide rail 141 and a slider 142 arranged in pairs. One of the guide rail 141 and the slider 142 is fixed to the body 11, and the other is fixed to the telescopic mechanism 12.

[0344] The guide mechanism 14 is used to play a role of limiting and guiding the movement of the telescopic mechanism 12 relative to the car body 11 in a direction perpendicular to the telescopic direction. A pair of matching guide rails 141 and sliders 142 are provided in the guide mechanism 14. By fixing the slider 142 to any one of the car body 11 and the telescopic mechanism 12, and fixing the other to the guide rail 141, a sliding fit between the guide rail 141 and the slider 142 is achieved, so that the telescopic mechanism 12 can be limited and guided in the direction perpendicular to the telescopic direction relative to the car body 11.

[0345] The fixed part 131 is a rack of preset length, the movable part 132 is a gear, the gear is arranged on the telescopic mechanism 12, and the rack is arranged on the box body 11. The sliding mechanism 13 also includes a driving motor 133 arranged on the telescopic mechanism 12 for driving the gear to rotate.

[0346] By specifically setting the fixed part 131 to a rack of a preset length, and setting the movable part 132 to a gear that cooperates with the rack, the rack is fixed on the car body 11, and the gear is fixed on the telescopic mechanism 12. The gear and the rack are meshed, and a driving motor 133 is set on the telescopic mechanism 12 to drive the gear to rotate. When the gear rotates, an interaction force is generated with the rack. Since the rack is fixed, the gear drives the telescopic mechanism 12 to move relative to the car body 11 in a direction perpendicular to the telescopic direction.

[0347] The driving motor 133 is connected to the adjacent fixed part 121 through a fixed mounting plate 1331. A mounting hole is provided on the fixed mounting plate 1331, and the rotating shaft of the driving motor 133 passes through the mounting hole and is connected to the gear; the bottom of the frame of the compartment 11 includes a crossbeam 111 arranged in a direction perpendicular to the telescopic direction of the telescopic mechanism 12, and the rack is fixedly connected to the crossbeam 111. The extension direction of the rack is perpendicular to the telescopic direction of the telescopic mechanism 12. The gear is driven to rotate by the driving motor 133 to move relative to the rack, thereby driving the telescopic mechanism 12 to move synchronously.

[0348] The drive motor 133 is fixedly connected to the fixed portion 121 of the telescopic mechanism 12 through a fixed mounting plate 1331. A mounting hole is provided on the fixed mounting plate 1331 to facilitate the fixed connection between the output shaft of the drive motor 133 and the gear to drive the gear to rotate.

[0349] Considering that the moving direction of the telescopic mechanism 12 is perpendicular to the telescopic direction, the rack is fixed on the beam 111 perpendicular to the telescopic direction of the telescopic mechanism 12, and the extension direction of the rack is perpendicular to the telescopic direction of the telescopic mechanism 12. When the gear rotates, it can only move in the direction perpendicular to the telescopic direction, thereby driving the telescopic mechanism 12 to move in the direction perpendicular to the telescopic direction.

[0350] Both ends of the fixing portion 121 are slidably connected to the beam 111 through the guide mechanism 14 . Both ends of the fixing portion 121 are located above the beam 111 . The lower part of the fixing portion 121 includes a downwardly protruding limiting base 1211 , and both ends of the limiting base 1211 are clamped between the two beams 111 .

[0351] The telescopic mechanism 12 is moved in a direction perpendicular to the telescopic direction through the sliding connection between the fixed part 121 and the cross beam 111. In order to realize the above movement function and limit the movement trajectory of the telescopic mechanism 12, a guide mechanism 14 and a limit base 1211 are provided. The guide mechanism 14 includes a slider 142 and a guide rail 141 to realize the sliding connection between the fixed part 121 and the telescopic mechanism 12. The guide rail 141 also limits the movement trajectory of the fixed part 121, and it can only move along the length direction of the guide rail 141. In order to further stabilize the movement trajectory of the telescopic mechanism 12, a downwardly protruding limit base 1211 is provided on the fixed part 121, and the two ends of the limit base 1211 are clamped between the two cross beams 111 to ensure that the telescopic mechanism 12 can only move in a direction perpendicular to the telescopic direction, thereby preventing angle deviation and affecting the accuracy of battery removal and placement.

[0352] Both beams 111 are provided with a positioning groove 1111 facing the fixing portion 121 . The guide rail 141 is at least partially located in the positioning groove 1111 . The slider 142 is fixedly connected to the fixing portion 121 , and the slider 142 is slidably engaged with the guide rail 141 .

[0353] By providing a positioning groove 1111 on the crossbeam 111 for fixing the guide mechanism 14, the trajectory of relative movement between the telescopic mechanism 12 and the body 11 is defined. Placing part or all of the guide rail 141 in the guide mechanism 14 in the positioning groove 1111 can effectively reduce the overall thickness of the body 11 and the telescopic mechanism 12 while improving the strength of the body 11. By sliding with the slider 142 fixed on the fixing portion 121 and the guide rail 141, the telescopic mechanism 12 can be moved in a direction perpendicular to the telescopic direction. In one embodiment, the guide rail 141 and the slider 142 are both contained in the positioning groove 1111, which limits the slider 142 and prevents it from detaching from the guide rail 141.

[0354] A battery exchange device 2 includes the battery transfer device 1 in any embodiment of the first aspect above.

[0355] The battery exchange device 2 provided in the embodiment of the second aspect of the present application includes the battery transfer device 1 in any embodiment of the first aspect, wherein, in the battery transfer device 1, the compartment 11 is used to support and fix the telescopic mechanism 12, and the telescopic mechanism 12 is used to extend out of the compartment 11 to take out the low-charged battery removed from the tram and put it into the battery compartment for charging, and take out the fully charged battery in the battery compartment for easy installation on the tram. Taking into account that the tram that needs to be replaced may have position deviation when parked, a sliding mechanism 13 is provided between the telescopic mechanism 12 and the compartment 11, and the telescopic mechanism 12 can be moved in a direction perpendicular to the telescopic direction according to the parking position of the tram, so as to align the battery pack of the tram, thereby improving the battery disassembly and assembly accuracy of the battery exchange device 2; on the other hand, the position of the telescopic mechanism 12 can be adjusted for battery packs at different positions in the battery compartment, and batteries at different positions in the battery compartment can be taken and placed, thereby improving the battery exchange flexibility and efficiency of the battery exchange device 2.

[0356] The battery-swapping device 2 also includes a battery-swapping mechanism 21 disposed on the top surface of the telescopic mechanism 12 . The telescopic mechanism 12 drives the battery-swapping mechanism 21 to extend into the bottom of the battery-swapping vehicle to replace the battery pack.

[0357] During the battery swap operation, the battery swap mechanism 21 located on the top surface of the telescopic mechanism 12 can be directly extended into the bottom of the battery swap vehicle through the telescopic mechanism 12 to perform the battery swap operation. This not only improves the efficiency of battery swapping, but also makes the battery swap operation simpler and faster. The entire battery swap device 2 has the functions of battery removal, installation, and battery transportation, which can ensure the rapid and safe replacement of battery packs, which is crucial to improving the convenience of use and maintenance efficiency of electric vehicles.

[0358] The battery replacement mechanism 21 includes a floating battery tray 211 and an unlocking pin 212 provided on the battery tray 211;

[0359] The battery tray 211 extends into the bottom of the battery-swapping vehicle through the telescopic movement of the telescopic mechanism 12, and the unlocking pin 212 unlocks or locks the battery pack as the battery tray 211 rises and falls and the telescopic movement of the telescopic mechanism 12.

[0360] The battery tray 211 is used to support the battery pack during the battery swapping process. Under the telescopic movement of the telescopic mechanism 12, the battery tray 211 extends into the bottom of the battery swapping vehicle. Since the battery tray 211 is a floating design, the floating characteristics of the battery tray 211 allow it to adapt to the shape and state of different battery swapping vehicle chassis, maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack. The unlocking pin 212 is brought into contact with the unlocking point of the battery pack as the battery tray 211 rises and falls and the telescopic movement of the telescopic mechanism 12, thereby unlocking or locking the battery pack, thereby improving the accuracy and efficiency of disassembly and assembly of the battery pack.

[0361] The battery exchange mechanism 21 also includes a bracket 213 , and the battery tray 211 is arranged higher than the bracket 213 . An elastic member 214 is provided on the bracket 213 for enabling the battery tray 211 to float.

[0362] The bracket 213 can support the battery tray 211 and improve the stability of the battery tray 211. The elastic member 214 on the bracket 213 makes the battery tray 211 floatable, which allows the battery tray 211 to adapt to the shape and state of different battery swap vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving the stability and safety during the battery swap process. In addition, the elastic member 214 can enable the battery tray 211 to adapt to different surfaces and pressures when contacting the bottom of the battery swap vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery swapping, but also ensures the simplicity of battery swapping operations and the safe replacement of battery packs.

[0363] The battery exchange mechanism 21 also includes a bracket 213 and a support plate 215 arranged on the bracket 213 . A sinking groove 2151 is formed on the support plate 215 , and the battery tray 211 is arranged in the sinking groove 2151 .

[0364] The battery tray 211 is placed in the sunken groove 2151 on the support plate 215, which reduces the overall height of the battery tray 211 on the bracket 213, making the overall thickness of the battery exchange mechanism 21 smaller and increasing the battery exchange space. In addition, the battery tray 211 is placed in the sunken groove 2151 on the support plate 215, which can ensure the stable position of the battery tray 211 during the battery exchange process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery exchange.

[0365] The battery tray 211 is also provided with at least two battery positioning pins 2111 ;

[0366] The battery positioning pins 2111 are distributed in the middle area of ​​the battery tray 211 along the length direction of the battery tray 211 .

[0367] The positioning pins on the battery tray 211 ensure the correct position of the battery pack during battery replacement, preventing it from shifting during movement or battery replacement, thereby improving the accuracy and safety of battery replacement. In addition, the battery positioning pins 2111 cooperate with the battery pack to produce a positioning and clamping effect on the battery pack, facilitating synchronous movement of the battery pack, making the battery pack more resistant to unlocking forces, and improving the stability of battery unlocking.

[0368] The battery exchange device 2 also includes a fixed support frame 22, and the compartment 11 can be raised and lowered and moved between the support frames 22. The lifting and lowering movement of the compartment 11 drives the battery exchange mechanism 21 to rise and fall synchronously to perform locking and unlocking operations on the battery pack.

[0369] The support frame 22 plays a vital role in the battery swap device 2. It provides stable support for the compartment 11, allowing the compartment 11 to be raised and lowered and moved therein. The lifting and lowering of the compartment 11 drives the battery swap mechanism 21 to be lifted and lowered synchronously. The unlocking pin 212 on the battery swap mechanism 21 can be accurately aligned with the battery pack to lock or unlock, thereby improving the safety and efficiency of the battery swap process, and increasing the flexibility of the battery swap device 2, making the battery pack replacement process more efficient and safe.

[0370] Example 3:

[0371] As shown in Figures 12 to 16, a battery transfer device 1 includes: a fixed support frame 11, a liftable compartment 12, and a telescopic mechanism 13 provided in the compartment 12 and capable of being telescoped and moved outward. The battery transfer device 1 also includes a moving component 14 provided between the support frames 11 and capable of being lifted and lowered along the support frames 11. The compartment 12 can be rotatably connected to the moving component 14 to adjust the direction of the telescopic mechanism 13.

[0372] The moving assembly 14 is provided to drive the body 12 to move up and down along the support frame 11, thereby adjusting the height of the telescopic mechanism 13. At the same time, the body 12 and the moving assembly 14 are rotatably connected, which facilitates the adjustment of the angle of the body 12, thereby adjusting the extension angle of the telescopic mechanism 13. When the battery-swapping electric vehicle is parked at a deflection angle, it can be accurately positioned and extended to achieve precise battery swapping.

[0373] The moving assembly 14 is disposed above the body 12 , and the top surface of the body 12 is rotatably connected to the bottom surface of the moving assembly 14 , so that the body 12 drives the telescopic mechanism 13 to rotate synchronously, thereby adjusting the direction of the telescopic mechanism 13 .

[0374] By setting the mobile component 14 above the compartment 12 and realizing rotation control by the top surface of the compartment 12, the bottom surface of the compartment 12 does not need any additional structure and can be set close to the ground, thereby improving the scope of application for transporting batteries at any height.

[0375] The support frame 11 includes a plurality of columns 111 formed on the outer periphery of the body 12.

[0376] The moving assembly 14 includes at least two moving parts 141 that are attached to the side walls of two adjacent columns 111 and can be lifted and lowered, and a linkage part 142 connected between the at least two moving parts 141 . The body 12 is rotatably connected to the bottom surface of the linkage part 142 .

[0377] By providing a plurality of columns 111 on the outer periphery of the body 12, the columns 111 cooperate with the movable assembly 14 to enable the movable assembly 14 to drive the body 12 up and down, thereby adjusting the extension height of the telescopic mechanism 13. The movable portion 141 provided in the movable assembly 14 cooperates with the columns 111 to achieve the lifting function, and the linkage portion 142 is provided to be rotatably connected to the body 12, thereby playing a role in positioning and supporting the body 12.

[0378] The linkage portion 142 includes at least two cross beams 1421 whose ends are respectively connected to the corresponding moving portions 141 and at least two longitudinal beams 1422 connected between the at least two cross beams 1421 . The bottom surfaces of the at least two longitudinal beams 1422 are formed with mounting surfaces for mounting the car body 12 .

[0379] The linkage part 142 is provided with at least two cross beams 1421 for connecting with the moving parts 141 on both sides. At least two longitudinal beams 1422 are provided to form an installation surface for installing the car body 12. At the same time, the longitudinal beams 1422 also strengthen the overall structural strength of the linkage part 142 to prevent deformation.

[0380] The battery transport device 1 further includes a rotating mechanism 15 disposed between the body 12 and the linkage portion 142 .

[0381] The rotatable connection between the body 12 and the linkage portion 142 is achieved through a rotating mechanism 15 .

[0382] The rotating mechanism 15 includes a slewing bearing assembly 151 disposed between the mounting surface and the body 12 and a driving assembly 152 for driving the slewing bearing assembly 151 to rotate.

[0383] One embodiment: The rotating mechanism 15 adopts a slewing support assembly 151 and a driving assembly 152 . The driving assembly 152 is used to drive the slewing support assembly to rotate, thereby driving the car body 12 to rotate.

[0384] The linkage portion 142 further includes a mounting plate 1423 fixed to at least the bottom surface of the longitudinal beam 1422. The surface of the mounting plate 1423 is formed with a mounting surface.

[0385] The driving assembly 152 includes a rotating shaft 1521 passing through the mounting surface, a gear 1522 disposed on the rotating shaft 1521 and meshing with the slewing support assembly, and a motor 1523 disposed on the top surface of the mounting plate 1423 and used to drive the rotating shaft 1521 to rotate.

[0386] The mounting plate 1423 is rotatably connected to the body 12 and is located between the longitudinal beams 1422 to ensure structural strength and to support the body 12 to prevent deformation.

[0387] In one embodiment, the driving assembly 152 includes a motor 1523 and a rotating shaft 1521. The rotating shaft 1521 is provided with a gear 1522. The gear 1522 is engaged with the slewing support assembly. The motor 1523 drives the gear 1522 to rotate, driving the slewing support assembly to rotate, thereby driving the car body 12 to rotate.

[0388] The linkage portion 142 further includes a first reinforcement portion 1424 disposed at least corresponding to the mounting surface.

[0389] Since the compartment 12 includes the telescopic mechanism 13 , a battery will be placed on the telescopic mechanism 13 during use. The first reinforcing portion 1424 is provided to strengthen the structural strength of the linkage portion 142 to prevent deformation.

[0390] The first reinforcement structure includes a plurality of reinforcement plates 14241. The two ends of the reinforcement plates 14241 are fixedly connected to the longitudinal beams 1422 at the two ends respectively, and the bottom of the reinforcement plates 14241 is fixedly connected to the mounting plate 1423.

[0391] And / or, the first reinforcement structure includes a plurality of reinforcement plates 14241 provided between the longitudinal beams 1422 , and a transition connection plate 14242 is further provided on the beam surface at the connection between the reinforcement plates 14241 and the longitudinal beams 1422 .

[0392] In one embodiment, the first reinforcement structure includes a plurality of reinforcement plates 14241, which are fixedly connected to the longitudinal beams 1422 and the mounting plate 1423 to enhance the structural strength of the entire linkage portion 142. To further enhance the structural strength of the linkage portion 142, a transition connecting plate 14242 may be provided on the beam surface where the reinforcement plates 14241 connect to the longitudinal beams 1422.

[0393] One end of the linkage portion 142 is rotatably connected to the corresponding moving portion 141 , and the other end of the linkage portion 142 is movably connected to the corresponding moving portion 141 .

[0394] In actual working environments, the chassis of a tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, it is necessary to adjust the tilt angle of the extended portion of the telescopic mechanism 13. By rotatably connecting one end of the linkage portion 142 to the corresponding movable portion 141 and movably connecting the other end to the corresponding movable portion 141, the two sides of the car body 12 can be raised to different heights, thereby achieving the purpose of tilting the car body 12. As the car body 12 tilts, the telescopic mechanism 13 inside the car body 12 is at the same tilt angle as the car body 12, and the extended portion can be well attached to the tram chassis, allowing battery removal and transportation.

[0395] One of the linkage portion 142 and the moving portion 141 is provided with a rotatable shaft 1521 , and the other is provided with a rotation hole 1412 or a moving groove 1413 matching the shaft 1521 .

[0396] In one embodiment, the body 12 is tilted by the rotational engagement of the rotating shaft 1521 with the rotating hole 1412, and the movement engagement of the rotating shaft 1521 with the movable slot 1413, thereby tilting the telescopic mechanism 13. Whether the rotating shaft 1521, rotating hole 1412, and movable slot 1413 are specifically disposed in the linkage portion 142 or the movable portion 141 is not specifically limited; the effects of the present technology can be achieved in either case.

[0397] The rotating hole 1412 is a circular hole matching the rotating shaft 1521 , and the moving groove 1413 is a waist-shaped hole extending along the length direction of the crossbeam 1421 .

[0398] In one embodiment, the circular hole cooperates with the rotating shaft 1521 to realize a rotational connection, and the waist-shaped hole cooperates with the rotating shaft 1521 to realize a rotational and movable connection.

[0399] The linkage portion 142 further includes a second reinforcement portion 1425 disposed near the moving portion 141 .

[0400] The linkage portion 142 includes a second reinforcement portion 1425, which can improve the structural strength of the connection area between the linkage portion 142 and the movable portion 141. Such reinforcement measures help ensure that during the battery pack transportation process, even under heavy loads, the battery transportation device 1 can remain stable and avoid deformation or damage due to weight, thereby improving the safety and reliability of battery transportation.

[0401] The second reinforcement portion 1425 includes a first reinforcement rib plate 14251;

[0402] The first reinforcing rib plate 14251 is provided at the connection portion of the transverse beam 1421 and the longitudinal beam 1422 , and is located on two upper and lower opposite beam surfaces of the transverse beam 1421 and the longitudinal beam 1422 .

[0403] First ribs 14251 are located at the junction of crossbeam 1421 and longitudinal beam 1422, and are arranged on two opposing beam surfaces. They provide additional structural support in both the horizontal and vertical directions, enhancing the stability and load-bearing capacity of crossbeam 1421 and longitudinal beam 1422, particularly at the junction, which is typically subject to greater stress. This reinforcement helps crossbeam 1421 and longitudinal beam 1422 resist deformation and damage during battery pack transportation, ensuring the safety of the battery pack.

[0404] The second reinforcement portion 1425 further includes a second reinforcement rib plate;

[0405] The edge of the second reinforcing rib abuts against the side wall of the horizontal beam 1421 and the side wall of the longitudinal beam 1422 .

[0406] The edge of the second reinforcing rib abuts against the side walls of the crossbeam 1421 and the longitudinal beam 1422, which can further improve the stability and deformation resistance of the battery transfer device 1 when subjected to lateral force, ensuring that during the battery pack transfer process, even if it is subjected to large lateral pressure, the battery transfer device 1 can maintain its structural stability.

[0407] The second reinforcement portion 1425 includes a diagonal beam 14253, which is arranged at the corner connection position of the horizontal beam 1421 and the longitudinal beam 1422, and the two ends of the diagonal beam 14253 are respectively connected to the horizontal beam 1421 and the longitudinal beam 1422, so that the diagonal beam 14253, the horizontal beam 1421 and the longitudinal beam 1422 form a triangular frame structure.

[0408] The triangular frame structure formed by the cable-stayed beam 14253, the cross beam 1421 and the longitudinal beam 1422 can provide better stability and load-bearing capacity, especially at the corner part where the cross beam 1421 and the longitudinal beam 1422 are connected, which is usually also the area where the force is concentrated. The triangular structure is stable and can effectively disperse and bear the load, thereby enhancing the structural strength and durability of the entire battery transport device 1.

[0409] A battery storage device 2 includes the battery transfer device 1 as described in any embodiment of the first aspect above; the battery storage device 2 also includes at least one battery rack 21 arranged on the side of the battery transfer device 1, and the battery rack 21 is provided with multiple battery positions distributed along the longitudinal direction, and the battery positions have a bay opening facing the compartment 12.

[0410] In the above scheme, the setting method of the battery rack 21 is flexible and highly scalable, and can adapt to the installation conditions of different installation environments, thereby improving space utilization and increasing the storage capacity of battery packs; the circumferential arrangement of multiple battery racks 21 around the battery transfer device 1 can make full use of the installation space on the side of the battery transfer device 1, and by cooperating with the rotatable compartment 12, the battery transfer device 1 can interact with the battery rack 21 at any position for battery packs, thereby improving the battery transfer efficiency.

[0411] There are multiple battery racks 21, which are arranged around the circumference of the battery transport device 1. The battery racks 21 and the support frame 11 share the same columns 111; alternatively, the battery racks 21 and the support frame 11 are independent of each other.

[0412] In one embodiment, three battery racks 21 are arranged at a 90° angle on the periphery of the battery exchange equipment 3. This arrangement fixes the single rotation angle of the compartment 12, making it more convenient to control the rotation of the compartment 12. Of course, the relative angles between the battery racks 21 can also be adjusted, so that the battery racks 21 and the battery exchange platform can be arranged in a pentagonal, hexagonal or other different arrangements on the periphery of the battery exchange equipment 3; in the above scheme, the battery rack 21 and the support frame 11 reuse the columns 111, further improving the structural strength between the battery rack 21 and the battery transfer device 1, which is beneficial to improving the safety of battery transfer; at the same time, this arrangement is beneficial to simplifying the structure of the battery rack 21 and / or the support frame 11, saving equipment costs; the battery rack 21 and the support frame 11 are independent of each other, which facilitates the overall rotation of the battery transfer device 1, avoids the interference of the columns 111 on the rotation of the compartment 12, and is more conducive to the flexible turning of the compartment 12 and the flexible arrangement of the battery rack 21.

[0413] Example 4:

[0414] As shown in Figures 17 to 19, a battery exchange device 1 includes: a support frame 11, a battery exchange body 12 arranged between the support frames 11 and capable of being raised and lowered, and a battery exchange device 13 arranged in the battery exchange body 12 and capable of being telescopically moved to the outside of the support frame 11. The battery exchange device 1 also includes a plurality of sliding mechanisms 14 that can be slidably arranged on the side walls of a plurality of columns 111 of the support frame 11. The battery exchange body 12 is connected between the plurality of sliding mechanisms 14, and one end of the battery exchange body 12 is rotatably connected to the corresponding sliding mechanism 14, and the other end is movably connected to the corresponding sliding mechanism 14.

[0415] The battery exchange body 12 can be raised and lowered on the support frame 11. Specifically, it is connected by sliding multiple sliding mechanisms 14 to adjust the height of the battery exchange device 13. When the battery needs to be removed and installed, it is adjusted to the height corresponding to the car chassis and then extended. When a low-charged battery needs to be placed in the battery compartment for charging or a fully charged battery needs to be taken out of the battery compartment, it is adjusted to the corresponding height of the battery compartment and then extended to take and place the battery.

[0416] In actual working environments, the chassis of a tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, it is necessary to adjust the tilt angle of the extended portion of the battery swap device 13. One end of the battery swap body 12 is rotatably connected to the corresponding sliding mechanism 14, and the other end is movably connected to the corresponding sliding mechanism 14. This allows the two sides of the battery swap body 12 to be raised to different heights, so that the extended portion of the battery swap device 13 can be well attached to the tram chassis for battery removal and transportation.

[0417] A rotating shaft 141 is provided on the end face of one of the battery exchange body 12 and the sliding mechanism 14, and a through hole 142 or a waist-shaped hole is provided on the other end face, thereby realizing a rotating connection or a movable connection between the battery exchange body 12 and the sliding mechanism 14.

[0418] In one embodiment, the battery swap body 12 is tilted by the rotational coordination of the rotating shaft 141 and the through hole 142, and the movement coordination of the rotating shaft 141 and the waist-shaped hole, thereby tilting the battery swap device 13. There is no specific limitation on whether the rotating shaft 141, through hole 142, and waist-shaped hole are specifically arranged on the battery swap body 12 or the sliding mechanism 14; all can achieve the effects of this technology.

[0419] The support frame 11 includes a plurality of columns 111 respectively arranged on the sides of the battery replacement body 12.

[0420] The plurality of sliding mechanisms 14 are respectively provided corresponding to two adjacent columns 111.

[0421] The battery-exchanging body 12 includes a body 121 provided with a battery-exchanging device 13 and a mounting portion 122 provided on the top surface of the body 121 , wherein the mounting portion 122 is connected between a plurality of sliding mechanisms 14 .

[0422] By setting a plurality of columns 111 around the battery-swapping body 12, the battery-swapping body 12 can be raised and lowered through the cooperation between the columns 111 and the sliding mechanism 14, thereby adjusting the height of the battery-swapping device 13. The compartment 121 is provided to provide a fixed support for the battery-swapping device 13. The upper part of the compartment 121 is connected to the sliding mechanism 14 through the mounting portion 122, so that the compartment 121 and the battery-swapping device 13 inside can be raised and lowered by the sliding mechanism 14.

[0423] The battery swapping device 1 also includes two independent lifting drive mechanisms 15 respectively arranged on both sides of the battery swapping body 12.

[0424] Two independent lifting drive mechanisms 15 are provided to independently control the lifting heights on both sides of the battery-exchanging body 12 , thereby enabling the battery-exchanging body 12 to be tilted.

[0425] In actual operation, the chassis of the tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, it is necessary to adjust the tilt angle of the extended part of the battery swap device 13. By independently controlling the lifting height of both sides of the battery swap body 12, the purpose of tilting the compartment 121 is achieved. When the compartment 121 tilts, the battery swap device 13 inside the compartment 121 is at the same tilt angle as the compartment 121, and the extended part can be well attached to the tram chassis for battery removal and transportation.

[0426] The battery exchange device 1 also includes a counterweight 16, and the lifting drive mechanism 15 includes a motor 151. Each column 111 is provided with a vertically movable counterweight 16, and the counterweight 16 is connected to the sliding mechanism 14 on its corresponding side through a chain 152. A sprocket 153 is provided above each column 111 to cooperate with the chain 152 on its side for transmission. The motor 151 drives the synchronous shaft to rotate, thereby simultaneously driving the two chains 152 located on the same side of the battery exchange body 12 to drive the sliding mechanism 14 to move vertically.

[0427] In one embodiment, the lifting drive mechanism 15 includes a motor 151. This motor 151 rotates the synchronous shaft, thereby simultaneously driving two chains 152 on the same side of the battery swap body 12, which in turn drive the sliding mechanism 14 to move vertically. This controls the height and tilt angle of the battery swap device 13, allowing precise battery swapping operations to be performed in close contact with the vehicle chassis. By providing a counterweight 16, chain 152, and sprocket 153 on each column 111 and connecting them to the sliding mechanism 14 on the corresponding side, synchronous lifting and lowering of the battery swap body 12 on the same side is achieved.

[0428] The counterweight 16 is located on the end side adjacent to or on the other side opposite to the battery-changing body 12 .

[0429] There are two settings for the counterweight 16. One is to be set on the end side adjacent to the battery swap body 12 to facilitate battery transportation between battery compartments. The other is to be set on the other side opposite to the battery swap body 12 to optimize the space utilization efficiency of the battery swap station.

[0430] There are four columns 111, and the mounting portion 122 includes two beams 1221 disposed at both ends corresponding to the columns 111.

[0431] The sliding mechanism 14 includes at least two sliding blocks 143 respectively mounted on the side walls of the pillar 111 and a connecting rod 144 connecting the sliding blocks 143 on both sides.

[0432] The mounting portion 122 is connected to the slider 143 in the sliding mechanism 14 that is corresponding to the side wall of the column 111 by setting a crossbeam 1221 that is set corresponding to the column 111. The sliding mechanism 14 is slidably connected to the column 111 through the slider 143. The two sliders 143 on the same side are connected and moved synchronously by setting a connecting rod 144, thereby realizing synchronous lifting and lowering of the same side of the compartment 121.

[0433] A rotating shaft 141 is provided on the side walls of the crossbeam 1221 near both ends, and a shaft sleeve 12212 is fixed inside the crossbeam 1221 to install the rotating shaft 141; a U-shaped lug 1441 is provided on the side wall of the connecting rod 144 facing the battery exchange body 12, and a through hole 142 or a waist-shaped hole is provided on the lug side wall of the U-shaped lug 1441.

[0434] A rotating shaft 141 and a sleeve 12212 for mounting the rotating shaft 141 are provided on the crossbeam 1221. The sleeve 12212 rotates with the through hole 142 on the connecting rod 144 and slides with the waist-shaped hole to achieve tilting of the body 121 and the internal battery exchange device 13. In this embodiment, a U-shaped lug 1441 is specifically provided on the connecting rod 144, and the through hole 142 and the waist-shaped hole are provided on the U-shaped lug 1441 to achieve the connection between the crossbeam 1221 and the connecting rod 144.

[0435] In an actual working environment, the chassis of the tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, it is necessary to adjust the tilt angle of the extended part of the battery-exchanging device 13. By rotatably connecting one end of the crossbeam 1221 to the corresponding connecting rod 144 and movably connecting the other end to the corresponding connecting rod 144, it is possible to raise the two sides of the car body 121 to different heights, thereby achieving the purpose of tilting the car body 121. When the car body 121 is tilted, the battery-exchanging device 13 in the car body 121 is at the same tilt angle as the car body 121, and the extended part can be well attached to the tram chassis for battery removal and transportation.

[0436] A U-shaped lug 1441 is provided on the side wall near both ends of the connecting rod 144, and a rotating shaft 141 is passed through the U-shaped lug 1441. Connectors 12213 matching the spacing between the two sliding mechanisms 14 are respectively provided at both ends of the crossbeam 1221. A through hole 142 or a movable groove is provided on the connecting member 12213. The through hole 142 is a circular hole that passes through the connecting member 12213 and matches the rotating shaft 141. The movable groove is a waist-shaped hole extending along the length direction of the crossbeam 1221 and passing through the connecting member 12213.

[0437] In this embodiment, a connecting piece 12213 is specifically provided on the crossbeam 1221, a through hole 142 and a waist-shaped hole are provided on the connecting piece 12213, and a rotating shaft 141 is provided on the sliding mechanism 14, which can also realize the tilting of the compartment 121 and the internal battery exchange device 13.

[0438] The sliding mechanism 14 includes a connecting rod 144 and a vertically arranged fixed plate 145 fixed at both ends of the connecting rod 144. At least two sliders 143 are sequentially provided on the side wall of each column 111 and one of the fixed plates 145 along the lifting direction, and a slide rail 146 that cooperates with the slider 143 is provided on the other side wall.

[0439] The fixed plate 145 and the column 111 are slidably connected via a slider 143 and a slide rail 146. Whether the slider 143 and slide rail 146 are positioned on the fixed plate 145 or the column 111 is not a specific requirement; both arrangements can achieve the desired lifting effect. The presence of at least two sliders 143 in sequence along the lifting direction defines the trajectory of the sliding mechanism 14, preventing deviation during lifting and improving stability.

[0440] At least two rollers 1451 are provided on two perpendicular side walls of the fixing plate 145 adjacent to the pillar 111 , and rolling surfaces 1111 cooperating with the rollers 1451 are provided on two mutually perpendicular side walls corresponding to the pillar 111 .

[0441] Another lifting coordination structure uses the coordination of the roller 1451 and the rolling surface 1111 to achieve the lifting and lowering of the battery replacement body 12.

[0442] The mounting portion 122 further includes a plurality of longitudinal beams 1222 vertically fixedly connected to the cross beam 1221, and a first reinforcement portion 1223 and a second reinforcement portion 1224.

[0443] The first reinforcement portion 1223 includes a plurality of reinforcement plates connecting two adjacent longitudinal beams 1222.

[0444] The second reinforcement portion 1224 includes a plurality of transition connection plates, and the transition connection plates are provided on the beam surface at the connection between the reinforcement plate and the longitudinal beam 1222 .

[0445] Since the compartment 121 includes a battery exchange device 13 and a battery is placed on the battery exchange device 13 during use, a reinforcing structure is required to strengthen the structural strength of the mounting portion 122 to prevent deformation.

[0446] In one embodiment, a plurality of reinforcing plates are designed, and transition connecting plates are provided on the beam surface at the connection between the reinforcing plates and the longitudinal beam 1222 .

[0447] The transition connecting plate includes a first reinforcing rib plate 12241;

[0448] The first reinforcing rib plate 12241 is provided at the connection portion between the connecting rod 144 and the longitudinal beam 1222 , and is located on two upper and lower opposite beam surfaces of the connecting rod 144 and the longitudinal beam 1222 .

[0449] First reinforcing ribs 12241 are located at the junction of connecting rod 144 and longitudinal beam 1222, and are arranged on two opposing beam surfaces. They provide additional structural support in both the horizontal and vertical directions, enhancing the stability and load-bearing capacity of connecting rod 144 and longitudinal beam 1222, especially at the junction, which is typically subjected to greater stress. This reinforcement helps connecting rod 144 and longitudinal beam 1222 better resist deformation and damage during battery pack transportation, ensuring the safety of the battery pack.

[0450] The transition connecting plate includes a second reinforcing rib plate 12242;

[0451] The edge of the second reinforcing rib 12242 abuts against the side wall of the connecting rod 144 and the side wall of the longitudinal beam 1222 .

[0452] The edge of the second reinforcing rib plate 12242 abuts against the side walls of the connecting rod 144 and the longitudinal beam 1222, which can further improve the stability and deformation resistance of the battery exchange body 12 when subjected to lateral force, and ensure that during the transportation of the battery pack, even if it is subjected to greater lateral pressure, the battery exchange body 12 can maintain its structural stability.

[0453] The second reinforcement part 1224 also includes a diagonal beam 12243, which is arranged at the corner connection position of the connecting rod 144 and the longitudinal beam 1222, and the two ends of the diagonal beam 12243 are respectively connected to the connecting rod 144 and the longitudinal beam 1222, so that the diagonal beam 12243, the connecting rod 144 and the longitudinal beam 1222 form a triangular frame structure.

[0454] The triangular frame structure formed by the cable-stayed beam 12243, the connecting rod 144 and the longitudinal beam 1222 can provide better stability and load-bearing capacity, especially at the corner part where the connecting rod 144 and the longitudinal beam 1222 are connected, which is usually an area where the force is more concentrated. The triangular structure is stable and can effectively disperse and bear the load, thereby enhancing the structural strength and durability of the entire battery exchange body 12.

[0455] The battery replacement device 13 includes a telescopic mechanism 131, a floating battery tray 132 provided on the telescopic mechanism 131, and an unlocking pin 133 provided on the battery tray 132;

[0456] The battery tray 132 extends into the bottom of the battery-swapping vehicle through the telescopic movement of the telescopic mechanism 131, and the unlocking pin 133 unlocks or locks the battery pack as the battery tray 132 rises and falls and the telescopic movement of the telescopic mechanism 131.

[0457] The battery tray 132 is used to support the battery pack during the battery swapping process. Under the telescopic movement of the telescopic mechanism 131, the battery tray 132 extends into the bottom of the battery swapping vehicle. Since the battery tray 132 is a floating design, the floating characteristics of the battery tray 132 allow it to adapt to the shape and state of different battery swapping vehicle chassis, maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack. The unlocking pin 133 is brought into contact with the unlocking point of the battery pack as the battery tray 132 rises and falls and the telescopic movement of the telescopic mechanism 131, thereby unlocking or locking the battery pack, thereby improving the accuracy and efficiency of disassembly and assembly of the battery pack.

[0458] The battery exchange device 13 also includes a bracket 134 , and the battery tray 132 is arranged higher than the bracket 134 . An elastic member 135 is provided on the bracket 134 for enabling the battery tray 132 to float.

[0459] The bracket 134 can support the battery tray 132 and improve the stability of the battery tray 132. The elastic member 135 on the bracket 134 makes the battery tray 132 floatable, which allows the battery tray 132 to adapt to the shape and state of different battery-swapping vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving the stability and safety during the battery-swapping process. In addition, the elastic member 135 can enable the battery tray 132 to adapt to different surfaces and pressures when contacting the bottom of the battery-swapping vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery swapping, but also ensures the simplicity of battery swapping operations and the safe replacement of battery packs.

[0460] The battery exchange device 13 further includes a bracket 134 and a support plate 136 arranged on the bracket 134 . A sinking groove 1361 is formed on the support plate 136 , and the battery tray 132 is arranged in the sinking groove 1361 .

[0461] The battery tray 132 is placed in the sunken groove 1361 on the support plate 136, which reduces the overall height of the battery tray 132 on the bracket 134, making the overall thickness of the battery exchange mechanism 151 smaller and increasing the battery exchange space. In addition, the battery tray 132 is placed in the sunken groove 1361 on the support plate 136, which can ensure the stable position of the battery tray 132 during the battery exchange process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery exchange.

[0462] The battery tray 132 is also provided with at least two battery positioning pins 1321;

[0463] The battery positioning pins 1321 are distributed in the middle area of ​​the battery tray 132 along the length direction of the battery tray 132 .

[0464] The positioning pins on the battery tray 132 ensure the correct position of the battery pack during battery replacement, preventing it from shifting during movement or battery replacement, thereby improving the accuracy and safety of battery replacement. In addition, the battery positioning pins 1321 cooperate with the battery pack to produce a positioning and clamping effect on the battery pack, facilitating synchronous movement of the battery pack, making the battery pack more resistant to unlocking forces, and improving the stability of battery unlocking.

[0467] In one embodiment, the battery tray 12 is used to support the battery pack during the battery swapping process. Under the telescopic movement of the battery swapping device, the battery tray 12 extends into the bottom of the battery swapping vehicle. Since the battery tray 12 is a floating design, the floating characteristics of the battery tray 12 allow it to adapt to the shape and state of different battery swapping vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack. The unlocking pin 13 is brought into contact with the unlocking point of the battery pack as the battery tray 12 rises and falls and the telescopic movement of the battery swapping device, thereby unlocking or locking the battery pack, thereby improving the accuracy and efficiency of disassembly and assembly of the battery pack.

[0468] Furthermore, the battery exchange device 1 also includes a bracket 14, the battery tray 12 is arranged higher than the bracket 14, and an elastic member 15 is provided on the bracket 14 for enabling the battery tray 12 to float.

[0469] In one embodiment, the bracket 14 can support the battery tray 12 and improve the stability of the battery tray 12. The elastic member 15 on the bracket 14 makes the battery tray 12 floatable, which allows the battery tray 12 to adapt to the shape and state of different battery swap vehicle chassis and maintain fit with the bottom of the vehicle, thereby achieving stable support for the battery pack and further improving the stability and safety during the battery swap process. In addition, the elastic member 15 can enable the battery tray 12 to adapt to different surfaces and pressures when contacting the bottom of the battery swap vehicle, ensuring that the battery pack can be smoothly unlocked or locked. This structural design not only improves the efficiency of battery swapping, but also ensures the simplicity of battery swapping operations and the safe replacement of battery packs.

[0471] In one embodiment, the battery tray 12 is placed in the sunken groove 161 on the support plate 16, which reduces the overall height of the battery tray 12 on the bracket 14, makes the overall thickness of the battery exchange 2323 mechanism smaller, and increases the battery exchange space. In addition, the battery tray 12 is placed in the sunken groove 161 on the support plate 16, which can ensure the stable position of the battery tray 12 during the battery exchange process and prevent displacement or tilting during the process of carrying the battery pack, thereby improving the safety and reliability of the battery exchange.

[0472] As an embodiment of the present application: at least two battery positioning pins 17 are further provided on the battery tray 12;

[0473] The battery positioning pins 17 are distributed in the middle area of ​​the battery tray 12 along the length direction of the battery tray 12 .

[0474] In one embodiment, the positioning pins provided on the battery tray 12 can ensure the correct position of the battery pack during the battery swap process, preventing it from shifting during movement or swapping, thereby improving the accuracy and safety of battery swapping. In addition, the battery positioning pins 17 cooperate with the battery pack to produce a positioning and clamping effect on the battery pack, facilitating synchronous movement of the battery pack, making the battery pack more resistant to unlocking forces, and improving the stability of battery unlocking.

[0475] As an embodiment of the present application, the battery swapping device 1 further includes a compartment 18 , and the telescopic mechanism 11 is slidably disposed in the compartment 18 ;

[0476] The sliding direction of the telescopic mechanism 11 is perpendicular to the telescopic direction of the telescopic mechanism 11 .

[0477] In one embodiment, the housing 18 supports and secures the telescopic mechanism 11. The telescopic mechanism 11 extends beyond the housing 18 to remove depleted batteries from the electric vehicle and place them in the battery compartment for charging, and to remove fully charged batteries from the compartment for installation in the electric vehicle. Considering that electric vehicles requiring battery replacement may be misaligned when parked, the telescopic mechanism 11 can be moved perpendicular to the telescopic direction based on the vehicle's parking position to align the battery packs. Furthermore, the position of the telescopic mechanism 11 can be adjusted to accommodate battery packs located at different locations within the battery compartment, allowing for access and placement of batteries from different locations within the compartment.

[0478] Furthermore, a sliding mechanism 19 is provided between the telescopic mechanism 11 and the body 18. The sliding mechanism 19 includes a fixed part 191 provided in the body 18 in a direction perpendicular to the telescopic direction and a movable part 192 movably provided on the fixed part 191. The telescopic mechanism 11 includes a fixed part 111 connected to the fixed part 191 or the movable part 192 and a telescopic part 112 movably connected to the fixed part 111.

[0479] In one embodiment, a fixed member 191 and a movable member 192 are provided within the sliding mechanism 19. The cooperation of these two structures enables the telescopic mechanism 11 to move perpendicularly relative to the housing 18 in a direction perpendicular to the telescopic direction. The telescopic mechanism 11 is provided with a fixed portion 111. This portion 111 moves perpendicularly between the sliding mechanism 19 and the housing 18, thereby driving the entire telescopic mechanism 11 to move perpendicularly relative to the housing 18 in a direction perpendicular to the telescopic direction. The fixed portion 111 is provided with a telescopic portion 112, which can extend outside the housing 18 to access batteries. The telescopic movement of the telescopic mechanism 11 is achieved through the movable connection between the telescopic portion 112 and the fixed portion 111.

[0480] In one embodiment, a guide mechanism 20 is provided between the telescopic mechanism 11 and the body 18 . The guide mechanism 20 includes a guide rail 201 and a slider 202 arranged in pairs. One of the guide rail 201 and the slider 202 is fixed to the body 18 , and the other is fixed to the telescopic mechanism 11 .

[0481] In one embodiment, the guide mechanism 20 is used to serve as a limit guide for the telescopic mechanism 11 to move relative to the car body 18 in a direction perpendicular to the telescopic direction. A pair of matching guide rails 201 and sliders 202 are provided in the guide mechanism 20. By fixing the slider 202 to any one of the car body 18 and the telescopic mechanism 11 and fixing the other to the guide rail 201, a sliding fit between the guide rail 201 and the slider 202 is achieved, thereby achieving a limit guide for the telescopic mechanism 11 to move relative to the car body 18 in a direction perpendicular to the telescopic direction.

[0482] Furthermore, the fixed part 191 is a rack of a preset length, the movable part 192 is a gear 2322, the gear 2322 is arranged on the telescopic mechanism 11, the rack is arranged on the box 18, and the sliding mechanism 19 also includes a drive motor 193 arranged on the telescopic mechanism 11 for driving the gear 2322 to rotate.

[0483] In one embodiment, the fixed member 191 is specifically set as a rack of a preset length, and the movable member 192 is set as a gear 2322 that cooperates with the rack. The rack is fixed on the body 18, and the gear 2322 is fixed on the telescopic mechanism 11. The gear 2322 and the rack are engaged. A driving motor 193 is set on the telescopic mechanism 11 to drive the gear 2322 to rotate. When the gear 2322 rotates, an interaction force is generated with the rack. Since the rack is fixed, the gear 2322 drives the telescopic mechanism 11 to move relative to the body 18 in a direction perpendicular to the telescopic direction.

[0484] Furthermore, the drive motor 193 is connected to the adjacent fixed portion 111 through a fixed mounting plate 2223, and a mounting hole is provided on the fixed mounting plate 2223, through which the rotating shaft 2321 of the drive motor 193 passes through the mounting hole and is connected to the gear 2322; the bottom of the frame of the compartment 18 includes a crossbeam 2221 arranged in a direction perpendicular to the telescopic direction of the telescopic mechanism 11, and the rack is fixedly connected to the crossbeam 2221, and the extension direction of the rack is perpendicular to the telescopic direction of the telescopic mechanism 11. The gear 2322 is driven to rotate by the drive motor 193 to move relative to the rack, thereby driving the telescopic mechanism 11 to move synchronously.

[0485] In one embodiment, the drive motor 193 is fixedly connected to the fixed portion 111 of the telescopic mechanism 11 via a fixed mounting plate 2223. A mounting hole is provided on the fixed mounting plate 2223 to facilitate the fixed connection between the output shaft of the drive motor 193 and the gear 2322 to drive the gear 2322 to rotate.

[0486] Considering that the moving direction of the telescopic mechanism 11 is perpendicular to the telescopic direction, the rack is fixed on the beam 2221 perpendicular to the telescopic direction of the telescopic mechanism 11, and the extension direction of the rack is perpendicular to the telescopic direction of the telescopic mechanism 11. When the gear 2322 rotates, it can only move in a direction perpendicular to the telescopic direction, thereby driving the telescopic mechanism 11 to move in a direction perpendicular to the telescopic direction.

[0487] Furthermore, both ends of the fixing portion 111 are slidably connected to the beam 2221 through the guide mechanism 20, and the two ends of the fixing portion 111 are located above the beam 2221. The lower part of the fixing portion 111 includes a downwardly protruding limit base 1111, and the two ends of the limit base 1111 are clamped between the two beams 2221.

[0488] In one embodiment, the telescopic mechanism 11 is moved in a direction perpendicular to the telescopic direction by a sliding connection between the fixed portion 111 and the crossbeam 2221. In order to realize the above movement function and limit the movement trajectory of the telescopic mechanism 11, a guide mechanism 20 and a limit base 1111 are provided. The guide mechanism 20 includes a slider 202 and a guide rail 201 to realize the sliding connection between the fixed portion 111 and the telescopic mechanism 11. The guide rail 201 also limits the movement trajectory of the fixed portion 111, and it can only move along the length direction of the guide rail 201. In order to further stabilize the movement trajectory of the telescopic mechanism 11, a downwardly protruding limit base 1111 is provided on the fixed portion 111, and the two ends of the limit base 1111 are clamped between the two crossbeams 2221 to ensure that the telescopic mechanism 11 can only move in a direction perpendicular to the telescopic direction, thereby preventing angle deviation and affecting the accuracy of battery removal and placement.

[0489] Furthermore, both cross beams 2221 are provided with a positioning groove 1811 facing the fixing portion 111 , the guide rail 201 is at least partially located in the positioning groove 1811 , the slider 202 is fixedly connected to the fixing portion 111 , and the slider 202 is slidably engaged with the guide rail 201 .

[0490] In one embodiment, positioning slots 1811 are provided on the crossbeam 2221 to secure the guide mechanism 20, thereby defining a trajectory for relative movement between the telescopic mechanism 11 and the body 18. Placing the guide rail 201 of the guide mechanism 20 partially or entirely within the positioning slots 1811 improves the strength of the body 18 while effectively reducing the overall thickness of the body 18 and the telescopic mechanism 11. The sliding engagement between the slider 202 secured to the fixing portion 111 and the guide rail 201 allows the telescopic mechanism 11 to move perpendicular to the telescopic direction.

[0491] In one embodiment, the guide rail 201 and the slider 202 are both contained in the positioning groove 1811 , which limits the position of the slider 202 and prevents the slider 202 from detaching from the guide rail 201 .

[0492] As an embodiment of the present application, the battery swapping device 1 further includes a compartment 18, and the telescopic mechanism 11 is slidably disposed in the compartment 18, wherein the sliding direction of the telescopic mechanism 11 is perpendicular to the telescopic direction of the telescopic mechanism 11;

[0494] By setting up a moving assembly 22, the body 18 is driven to move up and down along the support frame 21, thereby adjusting the height of the telescopic mechanism 11. At the same time, the body 18 and the moving assembly 22 are rotatably connected, which facilitates the adjustment of the angle of the body 18, thereby adjusting the extension angle of the telescopic mechanism 11. When the battery-swapping electric vehicle is parked at a deflection angle, it can be accurately positioned and extended to achieve precise battery swapping.

[0495] Furthermore, the moving assembly 22 is arranged above the box body 18, and the top surface of the box body 18 can be rotatably connected to the bottom surface of the moving assembly 22, so that the box body 18 drives the telescopic mechanism 11 to rotate synchronously to adjust the direction of the telescopic mechanism 11.

[0496] In one embodiment, since the battery-swap tram is parked manually, the body of the tram may be misaligned or have a certain deflection angle when parking. By setting a rotatable connection between the car body 18 and the moving component 22, when it is detected that the parking position of the tram has an angle deviation from the standard parking position, the car body 18 is controlled to rotate. While the car body 18 rotates, it drives the telescopic mechanism 11 to rotate synchronously, so that the extension direction of the telescopic mechanism 11 is perpendicular to the length direction of the tram body, so that the telescopic mechanism 11 can be accurately positioned and matched with the tram battery, and the battery can be accurately disassembled and placed.

The columns 211 cooperate with the movable assembly 22 to enable the movable assembly 22 to move the body 18 up and down, thereby adjusting the extended height of the telescopic mechanism 11. A movable portion 221 is provided in the movable assembly 22 to cooperate with the columns 211 to achieve the lifting function, and a linkage portion 222 is provided to be rotatably connected to the body 18, thereby providing positioning and support for the body 18.

[0500] Furthermore, the linkage portion 222 includes at least two cross beams 2221 whose ends are respectively connected to the corresponding moving portions 221 and at least two longitudinal beams 2222 connected between the at least two cross beams 2221 , and the bottom surfaces of the at least two longitudinal beams 2222 are formed with mounting surfaces for mounting the car body 18 .

[0508] In one embodiment, the mounting plate 2223 is rotatably connected to the body 18 , and the mounting plate 2223 is located between the longitudinal beams 2222 , thereby ensuring structural strength and supporting the body 18 to prevent deformation.

[0509] Furthermore, the driving assembly 232 includes a motor 2323 and a rotating shaft 2321. The rotating shaft 2321 is provided with a gear 2322. The gear 2322 is engaged with the slewing support assembly. The motor 2323 drives the gear 2322 to rotate, driving the slewing support assembly to rotate, thereby driving the car body 18 to rotate.

[0510] In one embodiment, one end of the linkage portion 222 is rotatably connected to the corresponding moving portion 221 , and the other end of the linkage portion 222 is movably connected to the corresponding moving portion 221 .

[0511] In one embodiment, in an actual working environment, the chassis of a tram may have a certain tilt angle and is not horizontal. In order to adapt to the tilt angle of the tram chassis, it is necessary to adjust the tilt angle of the extended portion of the telescopic mechanism 11. By rotatably connecting one end of the linkage portion 222 to the corresponding movable portion 221 and movably connecting the other end to the corresponding movable portion 221, the two sides of the car body 18 can be raised to different heights, thereby achieving the purpose of tilting the car body 18. As the car body 18 tilts, the telescopic mechanism 11 inside the car body 18 is at the same tilt angle as the car body 18, and the extended portion can be well attached to the tram chassis, allowing battery removal and transportation.

[0512] Furthermore, one of the linkage portion 222 and the moving portion 221 is provided with a rotatable shaft 2321 , and the other one is provided with a rotation hole or a moving groove matching the shaft 2321 .
