Description

Technical Field

The invention relates to the technical field of battery charging and replacing, in particular to a quick battery replacing system and a quick battery replacing method.

Background

With the technological progress and social development, various types of new energy vehicles such as pure electric vehicles and hybrid vehicles are increasingly widely used. In the case of these new vehicles, it is becoming increasingly important to have quick replacement of the batteries involved.

The battery replacement station is an automatic device for replacing batteries for the new energy vehicles, and mainly comprises a battery cabin, a charging cabinet, a control cabinet, an RGV (Rail Guided Vehicle, often referred to as a "battery replacement trolley" in the industry) and a battery replacement platform. Generally, after a vehicle enters a battery replacement station and stops on a battery replacement platform, the vehicle is lifted to a certain height through a lifting mechanism on the battery replacement platform, and a motor-lead screw transmission mechanism, a four-column lifting device and the like are used for leveling operation for multiple times, so that the battery unlocking operation can be accurately carried out after the RGV is moved to the bottom of the vehicle, and a power-lack battery can be unloaded from the vehicle. The RGV will then rotate through 90 ° to transport the deficient battery to the battery compartment lifting mechanism, where it is deposited into the battery compartment and the charged battery is removed from the battery compartment and then travels to the bottom of the vehicle via the RGV to be replaced on the vehicle. In addition, the internal space of the power conversion station is limited, so that the working environment is not ideal, and heat is easy to accumulate. Therefore, the existing battery replacement station generally has the problems of poor overall spatial layout, more complicated battery replacement operation, long consumed time, low battery conveying efficiency, inconvenient operation of replacing or adding new batteries, higher equipment input cost, non-ideal working environment and the like.

Detailed Description

First, it should be noted that the structure, composition, steps, features, advantages and the like of the fast swap system and the fast swap method of the present invention are specifically described below by way of examples, however, all the descriptions are only for illustrative purposes, and should not be construed as forming any limitation on the present invention.

In this context, the technical term "battery" includes, but is not limited to, batteries, battery packs, and the like used to power a vehicle, the technical term "vehicle load" refers to the weight of the vehicle itself, as well as the weight of items and/or occupants that may be loaded within the vehicle at the time, the technical term "connected" means directly and/or indirectly connecting one component to another component, and the technical terms "upper", "lower", "right", "left", "front", "rear", "vertical", "horizontal", derivatives thereof, and the like, are intended to relate to the orientation of the drawings, and the invention may assume a variety of alternative orientations, unless expressly stated otherwise.

Furthermore, to any single feature described or implicit in the embodiments herein or shown or implicit in the drawings, the invention still allows any combination or subtraction between these features (or their equivalents) to be performed, so that further embodiments according to the invention should be considered within the scope of this disclosure. In addition, for simplicity of the drawings, identical or similar parts and features may be indicated in the same drawing only in one or several places.

First, a basic layout and a structural configuration of an embodiment of the quick swap system according to the present invention are schematically illustrated in a top view in fig. 1, an exploded structural schematic diagram of the embodiment of the quick swap system is further illustrated in fig. 2, and the present invention will be described in detail by the above example.

In this given embodiment, the rapid battery swapping system includes a battery swapping platform 1 and a battery storage and transportation assembly, which may include a battery docking device 2, a battery compartment 3, and a transfer device 18, which may be arranged side by side as shown in fig. 1, thereby facilitating a compact layout.

As shown in fig. 1 and 2, the battery replacement platform 1 is a main platform for performing a battery replacement operation of a vehicle, and may be provided with a lifting mechanism, a detaching mechanism 14, and a conveying mechanism 15. The lifting mechanism is used for providing the function of lifting and lowering the vehicle parked on the battery replacing platform 1 to be used for the subsequent operation of disassembling, assembling and replacing the battery on the vehicle. In an alternative case, such as shown in fig. 1 to 4, the lifting mechanism may be configured to have a front wheel lifting device 12 and a rear wheel lifting device 13, which are respectively arranged at the front and rear of the power exchanging platform 1 for making corresponding contact with the front wheels 60 and the rear wheels 61 of the vehicle 6 to lift or lower the vehicle. In addition, the positioning operation of the vehicle on the battery replacing platform 1 can be realized through the front wheel lifting device 12 and the rear wheel lifting device 13, that is, some positioning mechanisms can be integrated in the front wheel lifting device 12 and the rear wheel lifting device 13, and such positioning mechanisms can include, but are not limited to, for example, a V-shaped groove, a ball screw device, and the like.

Different from the manner that the existing battery replacing station must lift the vehicle to a certain height so as to allow the RGV to travel to the lifted vehicle bottom space for battery replacement, in the battery replacing platform 1, the vehicle can be detached from the working surface of the battery replacing platform 1 and reach a preset height only through the lifting mechanism, so that the battery replacing operation can be performed on the vehicle. That is, the preset height may be a minimum height that enables the wheels of the vehicle to be separated from the working surface of the battery replacement platform 1 and enables the battery to be detached, for example, a distance that the vehicle can be suspended by air, which may ensure that the vehicle does not move on the battery replacement platform 1 due to the self-weight of the vehicle body when the vehicle battery is replaced. That is, after the vehicle 6 is driven into position by passing through the ramp 11 of the charging platform 1, the vehicle 6 can be lifted slightly to separate the

wheels

60 and 61 from the working surface of the charging platform 1, and then the subsequent charging operation can be performed.

Therefore, the preset height is obviously smaller than the vehicle lifting height required by the conventional battery replacement station, so that the lifting forming time of the vehicle and the time consumed by the whole battery replacement operation can be obviously shortened, the reduction of the electric energy consumption during the battery replacement is facilitated, and the battery replacement experience of a user is improved. In practical application, the invention allows the preset height to be flexibly selected and set according to specific requirements and the condition of the vehicle.

After the vehicle is lifted to the preset height, the vehicle battery can be disassembled and assembled through the disassembling and assembling mechanism 14 arranged in the battery replacing platform 1, so that the battery replacing work is completed.

After the battery (for example, a power-deficient battery, a failed battery, etc.) on the vehicle is unlocked and removed by the dismounting mechanism 14, the battery can be transferred to the transfer device 18 by the transfer mechanism 15 in the battery replacing platform 1, and the battery can be transferred to the battery docking device 2 by the latter, and then the battery can be transferred to the battery compartment 3 by the battery docking device 2 for storage, charging, etc. Furthermore, the transfer mechanism 15 can also receive the charged battery transferred from the battery docking device 2 and the transfer device 18, such charged battery being, for example, a fully charged battery from the battery compartment 3, and then transfer the charged battery to the vehicle 6 (e.g., under the vehicle) for subsequent loading and installation of the charged battery onto the vehicle 6 by the loading and unloading mechanism 14.

In practice, the above-mentioned disassembling and assembling mechanism 14 and the transfer mechanism 15 can be integrally arranged in a frame structure, and such a frame structure can be installed, for example, in the middle of the battery replacing platform 1 so as to correspond to the battery position which is usually installed at the bottom of the vehicle to facilitate the battery replacing operation.

After the battery is detached from the vehicle, the embodiment of the rapid battery replacement system adopts a completely different manner from the existing battery replacement system in the transmission motion of the battery, which can find a significant difference by comparing fig. 5 and fig. 6.

In the conventional battery replacement system shown in fig. 5, it is generally necessary to rotate a vehicle battery detached from a battery replacement platform by 90 ° as indicated by a rotation arrow in the figure, place the battery on an RGV, and then transport the battery to a battery compartment by the RGV.

With the present quick-change system embodiment, after the battery is removed from the vehicle, the battery may be directly conveyed outward via the conveying mechanism 15 in the direction D1 as shown by the arrow in the figure, that is, to the conveying device 18 and the battery docking device 3, which will be described in more detail later, without any direction adjustment of the battery, and the battery is conveyed by the latter to the battery compartment 3 for storage, charging and the like. Compared with the prior art shown in fig. 5, since no additional battery rotation adjustment action needs to be implemented in the battery replacement system, the removal of this link can effectively improve the battery replacement operation speed and increase the success rate of the battery replacement operation.

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

In the given embodiment, the exemplary map shows that the control unit 16 can be arranged at the rear of the charging platform 1, since in this implementation a ramp 11 is provided for the vehicle to enter or exit the charging platform 1, i.e. the vehicle will not enter the rear area of the charging platform 1, which area can be fully utilized for arranging the above-mentioned control unit 16. Of course, in some embodiments, the control unit 16 may be disposed at a side portion of the power exchanging platform 1, or disposed at any suitable position region such as a rear portion, a side portion, and the like of the power exchanging platform 1.

It should be noted that, in the prior art, it is common to arrange the control cabinet and the power swapping platform independently, and such a layout is already common in the industry and has been used by those skilled in the art as a standard model in the industry. Compared with the prior art, in the present embodiment, the control unit 16 having the same or similar functions as the existing control cabinet is integrated and arranged in the battery replacement platform, which not only breaks through the traditional layout design, but also enables the structural layout of the whole equipment to be more compact and beautiful, and enables the equipment installation and the battery replacement operation to be very convenient, fast, safe and reliable.

Referring to fig. 7 and 8, the basic structure of the battery docking device in the above embodiment of the rapid power conversion system is schematically shown.

In this example, the battery docking device 2 is disposed between the battery replacing platform 1 and the battery compartment 3 for transferring the battery, and the battery replacing platform 1 and the battery compartment 3 can be disposed on the left and right sides of the battery docking device 2 shown in fig. 1, which is beneficial to forming a very compact overall layout and effectively improving the space utilization rate.

As shown in fig. 7 and 8, the battery docking apparatus 2 may include a lifting unit 22, a translation unit 23, and a battery relay unit 24. Therein, a lifting mechanism 221 is provided in the lifting unit 22, and the lifting mechanism 221 may be, for example, a scissor-type lifting mechanism or any other suitable mechanism, and is used for performing a lifting motion in a first direction D1 as indicated in fig. 7, where the first direction D1 is perpendicular to a working plane of the power exchanging platform 1, and is generally a vertical direction of a site of the rapid power exchanging system.

In the alternative, the lifting unit 22 may be made of a frame structure, which not only ensures good overall structural strength, but also is effective in saving material, and may be efficiently produced by using various suitable machining processes, such as welding. Alternatively, the lifting mechanism 221 may be conveniently mounted directly to the frame structure of the lifting unit 22.

The translation unit 23 is connected to the lifting unit 22 so as to enable the lifting unit 22 to perform a translational movement in a second direction D2 as indicated in fig. 7, the second direction D2 being perpendicular to the first direction D1 and being generally optionally parallel to the longitudinal direction of the electrical switching platform 1.

As an exemplary illustration, in an alternative case, the translation unit 23 may be fixed on a field work surface (e.g., a ground surface, a base surface of a mobile charging station, etc.), and the guide member 231 may be provided on the translation unit 23, for example, a linear guide rail or the like may be provided on the bottom of the translation unit 23 as shown in fig. 8, and then a translational motion of the lifting unit 22 on the translation unit 23 is realized by an engaging member (e.g., a slider, a guide rail wheel, etc. which may be installed in the linear guide rail) which may be provided on the lifting unit 22 for engaging with the guide member 231, and the lifting unit 22 and the battery transfer unit 24 may be brought to a suitable position in association with the electric platform 1 or the battery compartment 3 by the translational motion so as to complete the battery transfer work.

In an alternative case, a power member 222 (e.g., a motor, etc.) may be provided in the lifting unit 22 to provide power for controlling the fitting member on the lifting unit 22 to perform a translational movement along the guide member 231 on the translation unit 23. Furthermore, in an alternative case, it is possible to arrange the lifting unit 22 and the translating unit 23 so as to be able to operate synchronously, which is very advantageous in that the above-mentioned translating movement and lifting movement can be performed simultaneously or substantially simultaneously, as required, whereby these respective operating times can be saved considerably.

The battery transfer unit 24 is connected to the lifting mechanism 221 of the lifting unit 22 so that the lifting mechanism 221 can be used to move up and down, and thus reach a suitable position associated with the battery changing platform 1 or the battery compartment 3 for battery transportation. Specifically, for example, as shown in fig. 7, the battery relay unit 24 may be installed in the frame structure of the lifting unit 22 and connected to the lifting mechanism 221 also arranged in the frame structure, so that the battery relay unit 24 is integrated into the frame structure of the lifting unit 22 similarly to the combination, which will effectively improve the space utilization and significantly reduce the overall occupied space of the apparatus.

Furthermore, the battery transfer unit 24 may be configured to have one or more battery compartments according to the actual application requirement, so that the battery (e.g. a dead battery, a faulty battery, etc.) detached from the vehicle parked on the power conversion platform 1 can be stored in the battery compartment, so as to be transferred and stored in the battery compartment 3 for storage, charging, etc. by the battery docking device 2; alternatively, the charged battery removed from the battery compartment 3 may be stored in a battery compartment of the battery transfer unit 24, and then transferred to the battery swapping platform 1 through the battery docking device 2, so as to be loaded on the vehicle to be swapped, which is parked on the battery swapping platform 1.

In an optional situation, the battery docking apparatus 2 may be configured such that, when it is in the initial position, one battery compartment of its battery transfer unit 24 corresponds to the outward transfer position of the battery unloaded from the vehicle on the battery replacing platform 1, for example, the height of the battery compartment at this time may be the same or substantially the same as the height of the unloaded battery ready to be transferred from the battery replacing platform 1 outward toward the battery docking apparatus 2, which may effectively save the corresponding operation processing time, and contribute to further improving the overall battery replacing efficiency and success rate.

In the given example of the battery docking apparatus, as shown in fig. 9 and 10, the battery relay unit 24 is exemplarily shown to have a two-layer battery compartment structure, i.e., an upper-layer battery compartment 241 and a lower-layer battery compartment 242, and for example, fig. 10 also shows the batteries 6 currently stored in the lower-layer battery compartment 242. In a specific application, one of the upper battery compartment 241 and the lower battery compartment 242 may be used for storing a battery detached from a vehicle parked on the battery replacing platform 1 (which is to be transferred to the battery compartment 3 for storage, charging, etc.), and the other may be used for storing a charged battery removed from the battery compartment 3 (which is to be transferred to the battery replacing platform 1 and loaded onto the vehicle), for example, the upper battery compartment 241 may be used for storing a charged battery, and the lower battery compartment 242 may be used for storing a low-power battery.

It is to be understood that the battery relay unit 24 may be configured to have three, four or more battery compartments that are to be stacked in the first direction D1 without departing from the spirit of the present invention, so that a greater number of batteries detached from the vehicle, charged batteries removed from the battery compartment 3 may be stored, which will contribute to effectively improving the work efficiency of the battery replacement operation. Of course, the present invention also allows the parallel arrangement of the battery compartments of the battery relay unit 24, or the parallel arrangement of the battery compartments and the stacking of a part of the battery compartments, so as to better meet various possible practical requirements.

In the conventional battery replacement systems, when a battery replacement operation is performed, a power-lack battery detached from a vehicle is generally conveyed to a designated position of a battery compartment by an RGV, and then a charged battery is taken out from other positions of the battery compartment for replacement to the vehicle, and the RGV travels back and forth for a relatively long conveying distance in the process, so that much time is consumed. In the technical solution of the present invention, by applying the conveying device 18 and the battery docking device 2 as described above, the battery storage locations in the battery docking device 2 can be used for storing various batteries (such as a charged battery, a power-deficient battery, a faulty battery, etc.), so that the number of round trips between the battery replacing platform and the battery storage can be significantly reduced, thereby greatly improving the battery replacing efficiency and reducing the time consumed by battery replacement.

Further, in an alternative case, at least one conveying member 240 (e.g., a conveyor belt, a roller, etc.) may be provided in one or more battery compartments in the battery relay unit 24, for example, as shown in fig. 5, one conveying member 240 may be provided in each of the front and rear of the battery compartment of the battery relay unit 24. By means of such a transfer member 240, the batteries can be moved into or out of the battery compartment along a third direction D3 as indicated in fig. 7, and since the third direction D3 is parallel to the battery access direction in the battery compartment 3 and the battery transfer direction of the transfer device 18, as described above, when transferring the batteries between the battery compartment 3 and the battery compartment of the battery relay unit 24, it is not necessary to adjust these battery transfer directions at all, thereby significantly reducing the time consumption in the battery transfer process and further increasing the efficiency of the battery transfer process.

In a preferred situation, as shown in fig. 18 and 19, for example, the battery access direction of the battery compartment 3, the battery access direction of the battery transfer unit 24 in the battery docking device, the battery transferring and arranging direction of the conveying device 18, and the battery arranging direction on the vehicle parked on the battery swapping platform 1 can be kept the same, for example, the batteries can be always conveyed, accessed and the like along the horizontal direction in the drawing (i.e., the transverse direction of the batteries shown in fig. 18), so that the charged batteries (or deficient batteries) can be always conveyed in the same direction during the transferring, storing, conveying and swapping operations among the battery compartment, the battery docking device, the conveying device, and the battery swapping platform without any unnecessary redundant actions (one 90 ° rotation motion is adopted to adjust the battery transferring direction as is mostly existed in the prior art solutions), which can significantly shorten the time for replacing the batteries, greatly improve the efficiency and success rate of the battery accessing operation, and thus can achieve a more efficient and faster and swapping operation.

As for the transfer device 18, it is arranged for transferring the battery between the battery changing platform 1 and the battery docking device 2. The conveyor 18 may comprise two or more sets of conveyor assemblies, such conveyor assemblies may be implemented in a chain, belt, drum, or any other suitable manner. According to the actual application requirement, the conveying assemblies can be arranged at any suitable positions at intervals at the outer range of the battery replacing platform 1 for conveying the batteries between the battery replacing platform 1 and the battery connecting device 2, and the heights of the conveying assemblies can be fixed or can be adjusted so as to better meet various possible actual requirements.

For example, as shown in fig. 19, at least a part of the transfer device 18 may be arranged in the bottom space of the battery compartment 3. Further, as in the example illustrated in fig. 11, the transfer assembly 4 may include a roller frame 41 and a roller set 42, and the roller frame 41 may be fixed to the changing platform 1, and the roller set 42 may be fixed to the roller frame 41. In an alternative case, the roller set 42 may be provided with at least one driving roller 421 and at least one driven roller 422. For example, in the roller set 42 shown in fig. 11, one driving roller 421 and two driven rollers 422 may be provided, and the driven rollers 422 may be disposed at both sides of the driving roller 421, respectively. In particular applications, two adjacent transfer assemblies may be arranged: the respective active rollers 421 are spaced apart from each other in the battery transfer direction by a distance not less than 1/2 of the width of the transferred battery, which enables better control of stability and reliability in battery transfer.

In addition, in some applications, the invention allows at least part of the transfer device 18 to be integrated into the battery docking device 2 or into the electrical exchange platform 1, for example, the transfer device 18 may be configured in the form of a conveyor belt, and such a conveyor belt may be allowed to be mounted integrally with the battery docking device 2 or onto the electrical exchange platform 1.

In an alternative scenario, a vehicle carrying assembly may be provided in the quick swap system embodiment discussed above for carrying the vehicle during a vehicle swap without any leveling operation. Reference will now be made to fig. 12-15, which schematically provide the basic structural composition of two load bearing devices in one example of a vehicle load bearing assembly, and their respective two operating states (i.e., an unloaded state in which no load is required and a loaded state in which load is required), by which the vehicle load bearing assembly can be formed, and which can be mounted to a battery replacement platform for carrying out the above-described functions of the vehicle load bearing assembly.

Specifically, in this example shown in fig. 12 and 13, the carrier device 17 includes a base 171, a bolster 172, and a power component (not shown), a situation in which the carrier device 17 is in an unloaded state is schematically illustrated in fig. 12, and a situation in which the carrier device 17 is in a loaded state is schematically illustrated in fig. 13.

The base 171 is mounted to the power exchanging platform 1, for example, as shown in fig. 14 and 15, and is used to support the entire carrying device 17. For example, the base 171 may be vertically mounted to the charging platform 1. In alternative aspects, the base 171 may be configured in a cylindrical shape (e.g., a circular post, a square post, etc.), or may be configured in any other suitable shape to better accommodate a variety of different application requirements.

The receiving portion 172 is connected to the base portion 171, for example, by hinging, welding, etc. The receiving portion 172 is configured to contact the vehicle to bear the weight thereof during battery replacement, and may be configured as a rod or any other suitable shape according to a specific application.

In this carrier 17, the power unit is arranged to provide power so that the above-mentioned bearing part 172 can move in a horizontal plane relative to the base part 171 and form a self-locking after moving into position (i.e. reaching a desired position). By performing the above movement, the state switching between the unloaded state and the loaded state of the loading device 17 can be realized, and the above self-locking function is provided, so that it is possible to avoid an undesirable problem such as the rattling of the receiving portion 172 when the vehicle is loaded.

By way of example, the powered member may be an electric motor, and the base 171 may be configured with an internal cavity for placement of the motor therein, such that the carrier may have a very compact configuration. In addition, since the carrying device 17 does not need to carry the vehicle load during the switching process between the no-load state and the carrying state, a motor with smaller power can be adopted for driving, which is also beneficial to reducing the occupied space of the motor. In some applications, the power member may be other components, units, devices, etc., and may be provided with a speed increasing mechanism, a speed reducing mechanism, etc.

As shown in fig. 12, when the carrying device 17 is in an unloaded state, an angle (e.g., 90 ° or other suitable value) can be formed between the bearing part 172 and the base part 171, and neither of them bears a load. When powered by a power component such as a motor, the receiving portion 172 can be rotated in a horizontal plane by an angle (e.g., 90 ° or other suitable value) relative to the base portion 171 to a desired position where the carrying device 17 is in a carrying state as shown in fig. 13, i.e., the carrying device 17 can be used to carry a vehicle load.

Referring next to fig. 14 and 15, another load bearing device that may be used in a vehicle load bearing assembly is illustrated and described in more detail below.

In this example, the carriage 17 includes a base 171, a bolster 172, and a power component (not shown), the carriage 17 being schematically illustrated in an unloaded condition in fig. 14, and the carriage 17 being schematically illustrated in a loaded condition in fig. 15. The corresponding description of the carrier shown in fig. 12 and 13 with respect to structure, composition, mounting arrangement, function, etc. applies equally to the carrier shown in fig. 14 and 15, unless specifically noted herein.

Unlike the previous carriage, in the unloaded state of the carriage 17 shown in fig. 14 and 15, an angle (e.g., 90 ° or other suitable value) may be formed between the bearing portion 172 and the base portion 171; when powered by a power component such as a motor, the receiving portion 172 can be rotated in a vertical plane by an angle (e.g., 90 ° or other suitable value) relative to the base portion 171 to a desired position, i.e., such that the carrying device 17 is now in a carrying state as shown in fig. 15, so that the carrying device 17 can be used to carry a vehicle load.

Two carrying devices are described above by way of example only, and either one of the carrying devices or both of the carrying devices may be used to form the vehicle carrying assembly in the quick-change system of the present invention.

In particular, in practical applications, the vehicle carrying assembly may comprise two or more such carrying devices, which may be mounted and arranged at any suitable position on the battery replacement platform, and when initially assembled, the difference in levelness between the carrying devices in the carrying state is controlled within a preset range (the specific precision requirement of the difference may be set according to practical applications), so as to ensure that when the vehicle to be replaced is placed on the carrying devices of the vehicle carrying assembly, the levelness standard required for the battery replacement operation using the assembly and disassembly mechanism is fully achieved, thereby avoiding the need of performing multiple leveling operations before the battery replacement operation as in the prior art. Therefore, the equipment cost for configuring a motor-lead screw transmission mechanism, a control program and the like can be saved, the battery replacement time can be obviously shortened due to the fact that the leveling operation process is cancelled, the overall operation is simplified, the use and maintenance cost is reduced, and the battery replacement efficiency and the success rate can be improved.

It will be appreciated that the use of the vehicle load bearing assembly described above provides these very significant technical advantages as discussed above in comparison with the prior art. The levelness difference/error exists in the machining precision and initial assembly of the bearing devices only once, and the levelness consistency of the bearing devices to the bearing contact surface of the vehicle can be ensured by strictly controlling the machining process and the assembly method. Of course, during use, it is possible to repair, replace, etc. certain load bearing devices of the vehicle load bearing assembly, and the difference/tolerance in levelness between these load bearing devices can be adjusted and controlled so as to be able to continue to meet the required levelness standard, thereby still eliminating the need for leveling operations that are common and necessary in the prior art.

In addition, it should be noted that, because the present invention adopts the innovative improved designs such as those above, there is no need to provide an electricity-changing traveling mechanism such as an RGV in the prior art, so that a series of parts such as a traveling motor, a rack and pinion, a bearing, a wheel, a rail and the like can be eliminated, thereby saving the manufacturing, assembling and maintenance costs. In addition, since the RGV generally has a high height, in order to ensure the access of the battery, the vehicle needs to be lifted to a certain height on the battery replacing platform to provide an operation space, which also results in that the driver and the passenger must leave the vehicle to allow the operation, and in the existing battery replacing system, the leveling operation needs to be performed in advance to ensure the accuracy of the battery disassembling and assembling operation, and if the driver and the passenger are always in the vehicle during the battery replacing operation, the activities of the driver and the passenger in the vehicle may bring adverse or even serious influence to the battery disassembling and assembling operation. By contrast, by adopting the technical scheme of the invention, the vehicle does not need to be leveled before the battery replacement operation, so that a driver and a passenger do not need to leave the vehicle during the battery replacement operation, the time consumption of the battery replacement operation can be greatly optimized, and the battery replacement use experience of a user can be remarkably improved.

Furthermore, it should be noted that the specific structural composition, construction, materials, number of arrangements, etc. of the load bearing means in the vehicle load bearing assembly are all allowed to be flexibly designed, changed and adjusted according to the design concept of the present invention, so as to be able to fully meet the various possible practical application requirements, without departing from the gist of the present invention.

By way of illustration, as shown in fig. 1 and 2, two or more carrying devices 17 of the type shown in fig. 12 and 13 may be mounted on one side of the electrical swapping platform 1 (e.g. the side close to the battery docking device 2), and when in an unloaded state, these carrying devices 17 may be arranged without bearing a load as shown in fig. 1, i.e. the bearing portion 172 of the carrying devices 17 may be kept parallel to the vehicle body direction/the longitudinal direction of the electrical swapping platform 1. When it is required to be in the loading state, the bearing portion 172 in the loading device 17 can be rotated by an angle (e.g. 90 ° or other suitable value) relative to the base portion 171 in the horizontal plane by a power component such as an electric motor, etc. to reach a desired position and form a self-locking function, so as to be used for bearing the load of the vehicle 6 to be replaced.

By way of further example, as shown in fig. 16 and 17, while two or more carrying devices 17 of the type shown in fig. 12 and 13 are mounted on one side of the swapping platform 1 (i.e. on the left side in fig. 16 and 17), two or more carrying devices 17 of the type shown in fig. 14 and 15 may be mounted on the other side of the swapping platform 1 (on the right side in fig. 16 and 17), and when in an unloaded state, these carrying devices 17 may be arranged in the direction shown in fig. 16 without bearing a load. When it is desired to put it in a load-bearing state, power can be supplied by a power component such as a motor or the like to rotate the bearing part 172 in the load-bearing device 17 in a vertical plane by an angle (e.g., 90 ° or other suitable value) relative to the base part 171 to a desired position as shown in fig. 17 and form a self-lock for subsequently bearing the load of the vehicle 6 to be replaced.

As shown in fig. 16 and 17, in an alternative case, it is possible to arrange a carrier 17 of the type shown in fig. 14 and 15 in the vicinity of the front wheel lifting device 12 and the rear wheel lifting device 13, respectively, which not only makes the overall structural layout more compact, but also facilitates better distribution and application of the load-bearing forces to suitable locations on, for example, the vehicle chassis.

In addition, in an optional situation, the charging device in the battery storage and transportation assembly of the quick battery replacement system of the present invention may be externally disposed, and then connected to the charging connector in the battery compartment 3 through a cable, so as to charge the battery stored in the battery compartment 3. The charging device generally has higher working power and higher heat productivity, so that the arrangement mode can effectively reduce the heat generation and accumulation in the installation space of the quick battery replacement system, thereby being beneficial to providing more ideal working environment of personnel and equipment operation environment.

Of course, as for the control cabinet 5 for controlling the battery compartment 3, for example, since the heating value thereof is small, it can be arranged in the quick charging system without being externally arranged.

In addition, in order to effectively control the amount of heat generated and accumulated at the battery compartment 3, a cooling device may be disposed in a vacant space such as the bottom of the battery compartment 3, which may be used not only to cool the batteries stored in the battery compartment 3, but also to further make full use of the system space. For the cooling device, for example, respective water cooling equipment, air cooling equipment, and the like may be used alone or in combination.

In addition, it should be noted that various possible expansion or layout adjustments can be made to the battery compartment in the battery storage and transportation assembly of the quick battery replacement system according to specific requirements, so that the system of the present invention can be well adapted to various application environments. For example, as shown in fig. 21, additional battery compartments 3' may be provided in some embodiments, which are disposed on both sides of the battery docking device 2, respectively with the battery compartments 3, in order to provide a larger battery storage capacity. For such an additional battery compartment 3', a separate control cabinet 5' can be provided. In practical applications, the battery compartment 3' may have the same or different structural design as the battery compartment 3, and their respective battery storage capacities may be flexibly selected, changed and adjusted according to various practical application requirements.

It should also be noted that, according to the technical solution of the present invention, it is also contemplated that in some application embodiments, a battery storage and transportation assembly is additionally provided, and the battery storage and transportation assembly may have the same, substantially the same, or similar composition structure as the battery storage and transportation assembly described above. Under the condition that the field space allows, the two battery storing and transporting assemblies can be respectively arranged on two sides of the battery replacing platform 1, so that not only can the battery storage capacity and the charging processing capacity of the rapid battery replacing system be increased by times, but also new batteries can be conveniently and directly supplemented and added to the respective battery bins of the two battery storing and transporting assemblies from the battery connecting device in any one of the two battery storing and transporting assemblies, and the existing new battery supplementing mode is that the new batteries are carried to the battery replacing platform and then carried and stored in the battery bins from the battery replacing platform through the RGV, and the existing modes are very complicated and time-consuming in operation. By contrast, the scheme of the invention can further improve the operation efficiency of battery access, transfer and replacement and shorten the whole power transfer time, thereby providing greater flexibility and expansibility for the system application of the invention. In addition, as one aspect which is obviously superior to the prior art, the invention also provides a quick battery replacement method. By way of illustration, as shown in fig. 21, the fast battery swapping method may include the steps of:

in step S11, a fast battery replacement system designed and provided according to the present invention is provided;

in step S12, a vehicle is driven into and parked on a battery replacement platform in the quick battery replacement system, and then the vehicle can be lifted to a preset height by a lifting mechanism of the battery replacement platform, so as to perform a battery disassembly and assembly operation on the vehicle;

in step S13, the battery docking device in the rapid battery swapping system (e.g., the battery docking device in the battery storage and transportation assembly located on one side of the battery swapping platform and/or the battery docking device in the battery storage and transportation assembly located on the other side of the battery swapping platform) may be used to transfer the battery between the battery compartment and the transportation device, and the transportation device in the rapid battery swapping system (e.g., the transportation device in the battery storage and transportation assembly located on one side of the battery swapping platform and/or the transportation device in the battery storage and transportation assembly located on the other side of the battery swapping platform) may be used to transfer the battery between the battery docking device and the battery swapping platform. As to the above-mentioned battery transfer, transfer and access operations, since the above description has been made in great detail in the foregoing description of the example of the quick swap system, reference may be made directly to the detailed description of the corresponding parts, and the description and discussion will not be repeated herein; and

in step S14, after the vehicle is subjected to the battery dismounting operation, the vehicle may be lowered onto the battery replacement platform through the lifting mechanism of the battery replacement platform, and then the vehicle is driven away from the battery replacement platform, so as to end the current battery replacement operation of the vehicle.

Of course, it should be noted that some operations in step S12 and step S13 above may not necessarily have a sequential execution order, for example, some operations in step S13 may occur before or after some operations in step S12, or it may be possible to execute them synchronously or substantially synchronously.

For example, when a battery (generally referred to as a "power-deficient battery") is dismounted from a vehicle parked on the battery swapping platform, some battery access relay operations can be synchronously executed, so that the overall battery swapping time can be obviously shortened, and the battery access operation efficiency can be greatly improved. For example, at this time, the charged battery may be moved from the battery compartment of the battery compartment into a battery compartment of the battery docking apparatus (e.g., an upper battery compartment located in the battery relay unit). For another example, the charged battery stored in the battery docking device may be removed therefrom and transferred to the transfer device, or the charged battery may be transferred from the transfer device toward the battery replacement platform. As another example, the battery docking device and/or the transfer device may be brought into position to wait for transferring the battery unloaded from the vehicle from the battery changing platform toward the battery compartment. For example, in combination with the above-discussed example of the rapid battery replacing system, the lifting unit of the battery docking device and the battery transferring unit may be translated together to the battery compartment of the battery compartment where the charged battery is available, and simultaneously the battery transferring unit is lifted and lowered in the vertical direction to the battery compartment of the battery compartment where the charged battery is available, so as to obtain the charged battery and then transfer the charged battery to the battery replacing platform through the transferring device.

For another example, when a charged battery is loaded on a vehicle parked on the battery swapping platform, some battery access transfer operations can be executed synchronously, which will also significantly improve the efficiency of battery access operations and significantly shorten the overall battery swapping time. For example, the battery detached from the vehicle may be transferred from the battery changing platform toward the battery compartment using the transfer device and the battery docking device. More specifically, in connection with the quick-change system example discussed above, the lifting unit of the battery docking apparatus and the battery transfer unit may be translated together to an empty battery compartment of the battery compartment, and simultaneously the battery transfer unit may be lifted in a vertical direction to the battery compartment, so that the unloaded battery may be moved into the battery compartment.

By adopting the above or similar operation modes, two or more operations (such as translation operation and/or lifting operation of the battery docking device, battery conveying operation of the conveying device and/or the battery docking device, battery disassembling and assembling operation of a vehicle parked on the battery replacing platform, various possible operations of two or more batteries in two battery storing and transporting assemblies positioned at two sides of the battery replacing platform at the same time, and the like) can be synchronously or substantially synchronously executed, so that the time consumption of the battery replacing operation on some intermediate links can be effectively overlapped, and the overall efficiency of operations such as battery transferring and storing can be remarkably improved.
