In addition, for any single technical feature described or implied in the embodiments mentioned herein, or any single technical feature shown or implied in each drawing, the present utility model still allows the use of these technical features ( or their equivalents) to continue any combination or deletion, so it should be considered that these more embodiments according to the present invention are also within the scope of the description herein. In addition, for the sake of simplifying the drawings, the same or similar parts and features may only be marked at one or several places in the same drawing.

Figure 1 schematically shows the basic layout and structural composition of an embodiment of a quick power exchange system according to the present invention in a top view, and Figure 2 further provides an example of the quick power exchange system embodiment Schematic diagram of the decomposition structure, the utility model will be described in detail below through the above examples.

In this given embodiment, the quick battery swap system includes a battery swap platform 1 and a battery storage and transportation component, the battery storage and transportation component may include a battery connection device 2 and a battery compartment 3, and the battery swap platform 1, The battery connection device 2 and the battery compartment 3 are arranged side by side as shown in FIG. 1 , which facilitates the formation of a compact layout.

As shown in FIG. 1 and FIG. 2 , the battery exchange platform 1 is the main platform for performing vehicle battery exchange operations, and it may be provided with a lifting mechanism, a dismounting mechanism 14 and a transmission mechanism 15 . As for the lifting mechanism, it is used to provide the function of lifting the vehicle parked on the power exchange platform 1 to a high degree, so that the battery on the vehicle can be replaced later. In an optional situation, for example, as shown in FIGS. 1 to 4 , the above-mentioned lifting mechanism can be configured to have a front wheel lifting device 12 and a rear wheel lifting device 13, and they are respectively arranged on the sides of the power exchange platform 1. The front part and the rear part are used to make corresponding contact with the front and rear wheels 60 and 61 of the vehicle 6 to raise the height of the vehicle. In addition, the positioning operation of the vehicle on the power exchange platform 1 can also be realized through the front wheel lifting device 12 and the rear wheel lifting device 13 .

Different from the way that the existing battery swapping station must lift the vehicle to a certain height so as to allow the RGV to drive to the space at the bottom of the lifted vehicle for battery replacement, in the above-mentioned battery swapping platform 1, only the lifting mechanism can be used To make the vehicle leave the working surface of the battery swap platform 1 and reach a preset height, the battery swap operation can be performed on the vehicle. That is, the preset height may be the minimum height at which the wheels of the vehicle are separated from the working surface of the power exchange platform 1 and the battery can be disassembled and installed, for example, the distance for the vehicle to be suspended by air, which can ensure that the vehicle body passes through when replacing the vehicle battery. The self-weight can prevent the vehicle from moving on the power exchange platform 1 . That is to say, when the vehicle 6 passes through the ramp 11 of the power exchange platform 1 and drives into place, it is only necessary to lift the vehicle 6 slightly so that the wheels 60, 61 are detached from the working surface of the power exchange platform 1, and then the Subsequent battery swap operations.

Therefore, the preset height is significantly smaller than the vehicle lifting height required by the existing power exchange station, which will significantly shorten the vehicle's lift formation time and the entire power exchange operation time, and is conducive to reducing the power consumption during the power exchange. Improve the user's battery replacement experience. In actual application occasions, the utility model allows flexible selection and setting of the aforementioned preset height according to specific requirements and the vehicle itself.

After the vehicle is lifted to the above preset height, the vehicle battery can be disassembled and assembled through the dismounting mechanism 14 provided in the battery exchange platform 1 , so as to complete the battery replacement work. After the battery (such as a dead battery, a faulty battery, etc.) Then the battery is transferred to the battery compartment 3 for storage, charging and other operations. In addition, the transfer mechanism 15 can also receive the charged battery transferred from the battery connection device 2, such a charged battery can be a fully charged battery from the battery compartment 3, and then transfer the charged battery to the vehicle 6 place (for example, under the vehicle), so that the charged battery can then be installed on the vehicle 6 by the dismounting mechanism 14 .

In practical applications, the above-mentioned dismounting mechanism 14 and the transmission mechanism 15 can be integrated and arranged in a frame structure, and such a frame structure can be installed, for example, in the middle of the power exchange platform 1, so as to be compatible with the The position of the battery at the bottom is corresponding to facilitate the operation of battery replacement.

After the battery is removed from the vehicle, this embodiment of the battery exchange system adopts a completely different method from the existing battery exchange system in terms of the battery’s transmission movement, which can be found by comparing Figure 5 and Figure 6 Significant difference.

In the existing battery replacement system shown in Figure 5, for the vehicle battery removed from the battery replacement platform, it needs to be rotated 90 degrees as shown by the rotation arrow in the figure and placed on the RGV, and then placed on the RGV by RGV transports it to the battery compartment, obviously the above rotation operation will consume extra time.

For this embodiment of the battery replacement system, after the battery is removed from the vehicle, it is not necessary to make any direction adjustments to the battery, but it is directly moved along the direction shown by the arrow in the figure via the transmission mechanism 15 D1 is transmitted outward, that is, to the battery connection device 3 which will be described in detail below, but the latter can finally be transmitted to the battery compartment 3 for storage, charging and other operations. Compared with the prior art shown in Figure 5, since there is no need to implement additional battery rotation adjustment in this battery swap system, removing this link can effectively improve the speed of the battery swap operation and increase the success rate of the battery swap operation .

In an optional situation, the control unit 16 for controlling the battery swapping operation can be integrated into the battery swapping platform 1, which will help to further optimize the same space layout, form a more compact overall structure, and facilitate operation and application.

In the example given, the exemplary map shows that the control unit 16 can be arranged at the rear of the power exchange platform 1, since in this implementation a ramp 11 is provided for the vehicle to enter or Driving out of the battery swapping platform 1 means that the vehicle will not drive into the rear area of the battery swapping platform 1 , so this area can be fully utilized for arranging the above-mentioned control unit 16 . Of course, in some embodiments, the control unit 16 can also be arranged, for example, on the side of the power exchange platform 1 , or in any suitable location such as the rear or side of the power exchange platform 1 .

It should be pointed out that in the prior art, the control cabinet and the power exchange platform are usually arranged independently. This layout method has long been commonplace in the industry, and has been used by those skilled in the art and has become the standard configuration mode in the industry. . Compared with this, in this embodiment, the control unit 16 with the same or similar functions as the existing control cabinet is integrated and arranged in the power exchange platform, which not only breaks through the traditional layout design, but also makes the entire equipment structure layout It is more compact and beautiful, and facilitates equipment installation and battery replacement operations, which are quite convenient, fast, safe and reliable.

Please refer to FIG. 7 and FIG. 8 , which schematically show the basic structural composition of the example of the battery connection device in the embodiment of the above-mentioned quick battery swapping system.

In this example, the battery docking device 2 is arranged between the battery exchange platform 1 and the battery compartment 3 for transferring batteries, and the battery exchange platform 1 and the battery compartment 3 can be respectively arranged at the battery interface shown in FIG. 1 . The left and right sides of the barge device 2 will help to form a very compact overall layout and effectively improve the space utilization rate.

As shown in FIGS. 7 and 8 , the battery connecting device 2 may include a lifting unit 22 , a translation unit 23 and a battery transfer unit 24 . Wherein, a lifting mechanism 221 is provided in the lifting unit 22, and the lifting mechanism 221 can adopt, for example, a scissor lifting mechanism or any other suitable mechanism for lifting in the first direction D1 as shown in FIG. 7 . Movement, the first direction D1 is perpendicular to the working surface of the power swapping platform 1, and generally speaking, it is the vertical direction of the quick power swapping system site.

In an optional situation, the lifting unit 22 can be made of a frame structure, which can not only ensure that it has a good overall structural strength, but also can effectively save materials, and can be efficiently processed by using various suitable processing techniques such as welding. Production. As an alternative, the lifting mechanism 221 can be directly installed on the frame structure of the lifting unit 22 very conveniently.

For the translation unit 23, it is connected with the lifting unit 22 so that the lifting unit 22 can perform a translational movement in the second direction D2 as shown in FIG. The direction D1 is perpendicular, and generally speaking, it can optionally be kept parallel to the longitudinal direction of the battery swapping platform 1 .

As an illustration, in an optional situation, the translation unit 23 can be fixed on the field work surface (such as the ground, the foundation surface of the mobile charging station, etc.), and a guide member 231 is set on the translation unit 23, for example, as shown in the figure As shown in 8, linear guide rails and the like are set at the bottom of the translation unit 23, and then through matching parts that can be arranged on the lifting unit 22 and used to cooperate with the guide member 231 (such as sliders that can be installed in the linear guide rail, rail wheels) etc.), so as to realize the translational movement of the lifting unit 22 on the translation unit 23, through which the translational movement can make the lifting unit 22 and the battery transfer unit 24 reach the appropriate position associated with the power exchange platform 1 or the battery compartment 3, so as to complete Battery delivery works.

In an optional situation, a power component 222 (such as a motor, etc.) may be provided in the lifting unit 22 to provide power for controlling the translational movement of the matching components on the lifting unit 22 along the guide component 231 on the translation unit 23 . In addition, in an optional situation, the lifting unit 22 and the translation unit 23 can be set to be able to operate synchronously, which will be very beneficial to perform the above-mentioned translation movement and lifting movement at the same time or substantially at the same time as required, thereby significantly saving These correspond to the processing time of the operations.

For the battery transfer unit 24, it is connected with the lifting mechanism 221 in the lifting unit 22, so that it can carry out lifting movement by means of the lifting mechanism 221, thereby reaching the suitable location associated with the battery exchange platform 1 or the battery compartment 3. location for battery delivery. Specifically, as shown in FIG. 7, for example, the battery transfer unit 24 can be installed in the frame structure of the lift unit 22, and connected with the lift mechanism 221 also arranged in the frame structure, so that the battery transfer unit 24 is similarly integrated into the frame structure of the lifting unit 22, which will effectively improve the space utilization rate and significantly reduce the overall occupied space of the equipment.

In addition, according to actual application requirements, the battery transfer unit 24 can be configured to have one or more battery compartments, so that the batteries (such as exhausted batteries, faulty batteries, etc.) battery, etc.) into the battery compartment, so that the battery can be transferred and stored in the battery compartment 3 through the battery connection device 2 for storage, charging, etc.; or, the charged battery removed from the battery compartment 3 can be stored to the battery compartment of the battery transfer unit 24, and then the charged battery is transferred to the battery exchange platform 1 through the battery connection device 2, so that it can be loaded onto a vehicle parked on the battery exchange platform 1 to be exchanged.

In an optional situation, the battery connection device 2 can be set so that when it is in the initial position, a battery compartment of its battery transfer unit 24 is in the same direction as the battery removed from the vehicle located on the battery exchange platform 1. Corresponding to the outer transfer position, for example, the height of the battery compartment at this time can be the same or substantially the same as the height of the unloaded battery when it is ready to be transferred outward from the battery exchange platform 1 toward the battery connection device 2, which can effectively save corresponding The operation processing time will help to further improve the overall power replacement efficiency and success rate. In the given example of the battery connection device, as shown in FIG. 9 and FIG. 10 , the battery transfer unit 24 is exemplarily shown as having a two-layer battery compartment structure, that is, an upper battery compartment 241 and a lower battery compartment 242, for example Also shown in FIG. 10 are the batteries 6 currently stored in the lower battery compartment 242 . In a specific application, one of the upper battery compartment 241 and the lower battery compartment 242 can be used to store the battery unloaded from the vehicle parked on the power exchange platform 1 (it will be transferred to the battery compartment 3 for storage and charging) etc.), the other is used to store the charged battery removed from the battery compartment 3 (it will be transferred to the power exchange platform 1 and loaded onto the vehicle), for example, the upper battery compartment 241 can be used to store the charged battery, The lower battery compartment 242 is used to store dead batteries.

It should be understood that, without departing from the gist of the present invention, the battery transfer unit 24 can be configured to have three, four or more layers of battery compartments, and these battery compartments will be stacked along the first direction D1 Therefore, a larger number of batteries removed from the vehicle and charged batteries removed from the battery compartment 3 can be stored, which will help to effectively improve the working efficiency of the battery replacement operation. Of course, the present invention also allows the battery compartments of the battery transfer unit 24 to be arranged in parallel, or part of them to be stacked during the parallel arrangement, so as to better meet various possible practical application requirements.

For the existing battery replacement systems, when they perform battery replacement operations, they generally transport the exhausted batteries unloaded from the vehicle to the designated position in the battery compartment by the AGV, and then take out a used battery from other positions in the battery compartment. The rechargeable battery is used to replace the vehicle, and the RGV will travel a relatively long distance in the above process, so it takes a lot of time. In contrast, by applying the above-mentioned battery connection device 2, multiple battery compartments can be used to store various batteries (such as charged batteries, dead batteries, faulty batteries, etc.), thereby significantly reducing The number of round-trips between the battery exchange platform and the battery compartment can greatly improve the efficiency of battery exchange and reduce the time-consuming of battery exchange.

In addition, in an optional situation, at least one conveying component 240 (such as a conveyor belt, a roller, etc.) can be set in one or more battery compartments in the battery transfer unit 24, such as shown in FIG. A transmission part 240 is respectively arranged at the front and the rear of the battery compartment. By means of such a transfer member 240, the battery can be moved into or out of the battery compartment along the third direction D3 as indicated in FIG. The battery delivery arrangement direction of the delivery mechanism 15 remains parallel. Therefore, as mentioned above, when batteries are delivered between the battery compartment 3 and the battery compartment of the battery transfer unit 24, there is no need to adjust these battery delivery directions at all. As a result, the time consumption in the battery transfer link can be significantly reduced, and the efficiency of the battery replacement operation can be further improved.

In an optional situation, a vehicle carrying component may be provided in the above-discussed embodiments of the quick battery swap system for carrying the vehicle during the vehicle battery swap without any leveling operation. Reference will be made to Figures 11 to 14 below, which exemplarily provide the basic structural composition of two types of carrying devices in an example of a vehicle carrying assembly and their respective two working states (that is, those that do not need to be carried The vehicle carrying assembly can be composed of these two carrying devices, and they can be installed on the power exchange platform to realize the above-mentioned functions of the vehicle carrying assembly.

Specifically, in the example shown in Figure 11 and Figure 12, the bearing device 17 includes a base 171, a receiving part 172 and a power component (not shown), and Figure 11 schematically shows that the bearing device 17 is in an unloaded state, and FIG. 12 schematically shows a situation in which the carrying device 17 is in a loaded state.

As for the base 171 , it is installed on the power exchange platform 1 as shown in FIGS. 13 and 14 , and is used to provide support for the entire carrying device 17 . For example, the base 171 can be installed vertically on the battery swapping platform 1 . In an optional situation, the base 171 can be configured in a column shape (such as a circular column, a square column, etc.), or it can be configured in any other suitable shape, so as to better adapt to various application requirements.

The receiving part 172 is connected with the above-mentioned base part 171, for example, the two can be connected together by means of hinge, welding and the like. The receiving portion 172 is configured to contact with the vehicle to bear its weight during battery replacement, and it can be configured as a rod or any other suitable shape according to specific application situations.

In the carrying device 17, the power component is configured to provide power, so that the above-mentioned receiving part 172 can move relative to the base part 171 in the horizontal plane, and after the movement is in place (that is, reaches the desired position) Self-locking. By carrying out the above-mentioned movement, the state switching between the unloaded state and the loaded state of the carrying device 17 can be realized, and due to the above-mentioned self-locking function, it is possible to avoid undesired problems such as shaking of the receiving part 172 when carrying the vehicle. question.

As an example, the above-mentioned power components may use a motor, and the base 171 may be configured to have an internal cavity for placing the motor therein, so that the carrying device may have a very compact structure. In addition, since the carrying device 17 does not need to carry the load of the vehicle during the switching process between the unloaded state and the loaded state, it can be driven by a motor with less power, which is also beneficial to reduce the space occupied by the motor. Certainly, in some application occasions, the above-mentioned power components may also use other components, units or devices, for example, it is possible to set a speed-up mechanism, a deceleration mechanism and the like.

As shown in FIG. 11 , when the carrying device 17 is in an unloaded state, an angle (such as 90 degrees or other appropriate values) can be formed between the receiving portion 172 and the base portion 171 , and neither of them bears load at this time. When the power is provided by power components such as motors, etc., the receiving part 172 can be rotated by an angle (such as 90 degrees or other suitable values) relative to the base 171 in the horizontal plane to reach the desired position. 17 is in the loading state shown in FIG. 12 at this position, that is, the bearing device 17 can be used to bear the vehicle load at this time.

Next, please refer to FIG. 13 and FIG. 14 , which show another kind of carrying device that can be used for the vehicle carrying assembly, which will be described in detail below.

In this example, the carrying device 17 includes a base portion 171, a receiving portion 172 and a power component (not shown). In FIG. 14 schematically shows the situation that the carrying device 17 is in a carrying state. Unless otherwise specified herein, the corresponding descriptions on the structure, composition, installation arrangement, function, etc. of the carrying device shown in Figures 11 and 12 are also applicable to the carrying device shown in Figures 13 and 14 .

Different from the aforementioned carrying device, for the carrying device 17 shown in Figure 13 and Figure 14, in its unloaded state, an angle (such as 90 degrees or other Appropriate value); when power is provided by power components such as motors, etc., the receiving portion 172 can be rotated at an angle (such as 90 degrees or other appropriate values) relative to the base 171 in the vertical plane to reach the desired value , that is, the carrying device 17 is in the carrying state as shown in FIG. 14 at this time, so that the carrying device 17 can be used to carry vehicle loads.

The two carrying devices are described above by way of example only, and any one of the carrying devices or both of them can be used to form the vehicle carrying assembly in the quick power exchange system of the present invention.

Specifically, in practical applications, the vehicle load-carrying assembly may include two or more such load-bearing devices, which may be installed and arranged at any suitable position on the power exchange platform, and during the initial assembly, these When the carrying devices are in the carrying state, the level difference between each other is controlled within the preset range (the specific difference accuracy requirements can be set according to the actual application situation), so that it can be guaranteed When the battery-changing vehicle is placed on these bearing devices of the vehicle-carrying components, it can fully meet the levelness standard required for the battery-changing operation using the disassembly mechanism, so that it is not necessary to perform the battery-changing operation as in the prior art. Perform multiple leveling operations. In this way, it can not only save the cost of equipment such as motor-screw transmission mechanism and control program, but also can significantly reduce the power replacement time due to the cancellation of the leveling operation process, simplifies the overall operation, reduces the use and maintenance cost, and can improve the replacement. Electrical efficiency and success rate.

It can be understood that, compared with the prior art, the adoption of the above-mentioned vehicle carrying assembly has obvious technical advantages as discussed above. The above-mentioned levelness difference/error only exists once in the machining accuracy and initial assembly of these bearing devices, and the consistency of the levelness of the load-bearing contact surface of these bearing devices on the vehicle can be ensured by strictly controlling the processing technology and assembly method.

In addition, it should be noted that since the utility model adopts such innovative improved designs as above, there is no need to set up a power-changing travel mechanism such as the RGV in the prior art solution, which can remove such as travel motors, gears, etc. A series of parts such as racks, bearings, wheels, tracks, etc. saves manufacturing, assembly and maintenance costs. In addition, since the RGV usually has a relatively high height, in order to ensure the access of the battery, the vehicle needs to be lifted to a certain height on the battery exchange platform to provide an operating space, which also results in the driver and passengers having to leave the vehicle to allow Action, and in the existing battery replacement system, pre-leveling operations are required to ensure the accuracy of the battery removal operation. If the driver and passengers are always in the vehicle during the battery replacement operation, their activities in the vehicle It may have adverse or even serious effects on the operation of disassembling and installing the battery. In contrast, with the technical solution of the utility model, it is not necessary to perform leveling operations on the vehicle before the battery replacement operation, so that the driver and passengers do not need to leave the vehicle during the battery replacement operation, which not only greatly optimizes the time-consuming operation of the battery replacement operation , and can significantly improve the user's battery replacement experience.

In addition, it should be pointed out that, without departing from the gist of the utility model, for the bearing device in the vehicle bearing assembly, its specific structural composition, construction form, material, setting quantity, etc. are all allowed according to the utility model Flexible design, change and adjustment based on advanced design ideas, so as to fully meet various possible practical application requirements.

When it needs to be placed in a loaded state, power can be provided by power components such as motors, etc., so that the receiving portion 172 in the carrying device 17 rotates an angle (such as 90 degrees or other suitable values) relative to the base 171 in the horizontal plane. , reach the desired position and form a self-lock, so as to be used to carry the load of the vehicle 6 to be replaced later.

For another example, as shown in Figure 15 and Figure 16, two or more bearing devices 17 of the type shown in Figure 11 and Figure 12 are installed on one side of the power exchange platform 1 (that is, Figure 15 and Figure 12 At the same time as the left side in Figure 16), two or more bearing devices 17 of the type shown in Figure 13 and Figure 14 can be installed on the other side of the power exchange platform 1 (as shown in Figure 15 and Figure 16 The right side of ), when in an unloaded state, these carrying devices 17 can be arranged in the direction shown in Figure 15 without bearing load. When it is necessary to make it in a loaded state, power can be provided by power components such as motors, etc. so that the receiving portion 172 in the carrying device 17 rotates an angle (such as 90 degrees or other suitable values) relative to the base 171 in the vertical plane. ), it reaches the desired position as shown in FIG. 16 and forms a self-lock, so as to carry the load of the vehicle 6 to be replaced later.

As shown in Figure 15 and Figure 16, in an optional situation, the carrying device 17 of the type shown in Figure 13 and Figure 14 can be arranged respectively in the vicinity of the front wheel lifting device 12 and the rear wheel lifting device 13, so not only The overall structural layout can be made more compact, and it is beneficial to better distribute and apply load-bearing forces to suitable positions on, for example, the vehicle chassis.

This is because this type of charging device generally has a large working power and a large heat generation, so the above arrangement can effectively reduce the generation and accumulation of heat in the installation space of the quick power exchange system, thereby helping to provide more ideal personnel work. environment and device operating environment.

Of course, for example, the control cabinet 5 used to control the battery compartment 3 can be arranged in the quick battery replacement system without external installation because of its low heat generation.

In addition, in order to effectively control the heat generated and accumulated in the battery compartment 3, a cooling device 4 can also be arranged in the empty space such as the bottom of the battery compartment 3, which can not only be used to cool the batteries stored in the battery compartment 3, but also It is also beneficial to further make full use of the system space. For the above cooling devices, for example, water cooling equipment, air cooling equipment, etc. can be used alone or in combination.

In addition, it should be noted that various possible extensions or layout adjustments can be made to the battery compartment in the battery storage and transportation component of the quick battery exchange system according to specific requirements, so that the system of the present invention can well adapt to various Application Environment.

As an example, the battery compartment 3 can be configured to include one or more identical battery compartment units, and these battery compartment units can be arranged side by side, such as shown in Figure 17 exemplarily, two batteries can be Bin units are arranged side by side to provide greater battery storage capacity. For each battery compartment unit, it can be configured to have N layers, and each layer has M battery compartments, and the above two parameters N and M can be positive integers that are the same or different. Of course, the utility model also allows the battery compartment 3 to include two or more different battery compartment units, that is, they can have different structural designs, and the respective battery storage capacities can be flexibly adjusted according to various practical application requirements. Choose, change and adjust.

It should also be pointed out that, according to the technical solution of the present utility model, it may also be considered to add a battery storage and transportation component in some application embodiments. The same, substantially the same or similar compositional structure. If the on-site space permits, the two battery storage and transportation components can be arranged on both sides of the battery exchange platform 1, so that not only can the battery storage capacity and charging processing capacity of the quick battery exchange system be doubled, but also The operation efficiency of battery access, transfer and replacement can be further improved, and the overall power replacement time consumption can be shortened, so that the system of the utility model has stronger adaptability, flexibility and expansibility. In addition, as an aspect obviously superior to the prior art, the utility model also provides a quick battery replacement method. As an example, as shown in Figure 18, the quick battery replacement method may include steps:

In step S11, provide the quick power exchange system designed and provided according to the utility model;

In step S12, the vehicle is driven into and parked on the battery exchange platform in the quick battery exchange system, and then the vehicle can be lifted to a preset height by the lifting mechanism of the battery exchange platform, so that the vehicle can be recharged later. Disassembly operation;

In step S13, the battery connection device in the quick battery exchange system (for example, the battery connection device in the battery storage and transportation component located on one side of the battery exchange platform and/or the battery located on the other side of the battery exchange platform The battery connection device in the storage and transportation component) transfers the battery between the battery compartment and the battery replacement platform. As for the above-mentioned battery transmission, transfer and access operations, since a very detailed description has been made in the previous example description of the fast battery swap system, you can directly refer to the specific description of the corresponding part above, and will not repeat the introduction and description here. discuss; and

In step S14, after the battery disassembly and assembly operation of the vehicle is completed, the vehicle can be lowered onto the battery exchange platform through the lifting mechanism of the battery exchange platform, and then the vehicle is driven away from the battery exchange platform, thereby ending the current Vehicle battery replacement operation.

Of course, it should be pointed out that some operations in the above step S12 and step S13 may not necessarily have a sequence of execution, for example, some operations in step S13 may occur before or after some operations in step S12, or they may be synchronized Execution or basically synchronous execution.

For example, while removing the battery (often referred to as a "depleted battery") from a vehicle parked at a battery swap platform, some battery access transfer operations can be performed simultaneously, thereby significantly reducing the overall battery swap time , greatly improving the efficiency of battery access operations. For example, at this time, the charged battery can be moved from the battery compartment of the battery compartment to the battery compartment of the battery connection device (eg, the upper battery compartment located in the battery transfer unit). For another example, at this time, the battery connection device can be placed in place to wait for the battery unloaded from the vehicle to be moved from the battery exchange platform to its battery compartment, and then the charged battery is transferred from the battery connection device to the battery exchange platform. For another example, in combination with the example of the quick battery swap system discussed above, at this time, the lifting unit of the battery connection device and the battery transfer unit can be translated together to the battery compartment where the charged battery can be taken in the battery compartment, and the battery can be transferred at the same time The unit goes up and down in the vertical direction to the battery compartment where the charged battery is available in the battery compartment, so that the charged battery can be obtained and then transferred to the power exchange platform through the battery connection device.

For another example, while loading the charged battery on the vehicle parked on the battery exchange platform, some battery access transfer operations can be performed simultaneously, which will also significantly improve the efficiency of battery access operations and significantly shorten the overall battery exchange time. For example, at this time, the battery docking device can be used to transfer the battery unloaded from the vehicle from the battery replacement platform to the battery compartment, so that it can be finally moved into the battery compartment of the battery compartment. More specifically, in combination with the example of the quick battery swap system discussed above, the lifting unit of the battery connection device and the battery transfer unit can be translated together to an empty battery compartment of the battery compartment, and at the same time the battery transfer unit can be placed in the Vertically go up and down to the battery compartment, so that the removed battery can be moved into the battery compartment.

By adopting the above or similar operation methods, two or more operations (such as the translation operation and/or lifting operation of the battery connection device, the vehicle parked on the battery exchange platform, etc.) can be performed simultaneously or substantially simultaneously. The battery disassembly operation, the various possible operations of two or more batteries at the same time in the two battery storage and transportation components located on both sides of the battery exchange platform, etc.), so that the battery exchange operation can be effectively superimposed in some intermediate The time-consuming link has significantly improved the overall efficiency of operations such as battery transfer and access.

The above is only an example to illustrate in detail the quick power exchange system and the quick power exchange method according to the present invention. These examples are only used to illustrate the principle of the present invention and its implementation, rather than to limit the present invention. Those skilled in the art can make various modifications and improvements without departing from the spirit and scope of the present invention. Therefore, all equivalent technical solutions should belong to the scope of the utility model and be limited by the claims of the utility model.
