Detailed Description
First, it should be noted that the structures, compositions, steps, features, advantages, and the like of the quick-change system and the quick-change method of the present invention will be specifically described below by way of example, however, all descriptions are merely for illustration, and should not be construed as limiting the present invention in any way.
In this context, the term "battery" includes, but is not limited to, a battery pack, etc. for powering a vehicle, the term "vehicle load" refers to the weight of the vehicle itself and the weight of items and/or occupants that may be loaded in the vehicle at this time, the term "connected" means that one component is directly and/or indirectly connected to another component, the terms "upper", "lower", "right", "left", "front", "rear", "vertical", "horizontal", and the like should be taken in connection with the orientation in the drawings, and the invention may take a variety of alternative orientations unless specifically indicated otherwise.
Furthermore, to the extent that any individual feature described or implied in the embodiments set forth herein, or any individual feature shown or implied in the figures, the invention still allows any combination or deletion of such features (or equivalents thereof) to continue, and further embodiments in accordance with the invention are considered to be within the scope of the disclosure herein. In addition, for the sake of simplicity of the drawing, identical or similar parts and features may be indicated at one or several places in the same drawing.
A basic layout and structural composition of an embodiment of the quick-change system according to the present invention is schematically illustrated in a top view in fig. 1, and an exploded structural schematic view of the embodiment of the quick-change system is given in fig. 2, and the present invention will be described in detail by way of the above examples.
In this given embodiment, the quick change system comprises a battery change platform 1 and a battery storage assembly, which may comprise a battery docking device 2 and a battery compartment 3, the battery change platform 1, the battery docking device 2 and the battery compartment 3 may be arranged side by side as shown in fig. 1, thereby facilitating a compact layout.
As shown in fig. 1 and 2, the power exchanging platform 1 is a main platform for performing a vehicle power exchanging operation, and may be provided with a lifting mechanism, a dismounting mechanism 14, and a conveying mechanism 15. As for the lifting mechanism, it is a function for providing a high lifting of the vehicle parked on the battery changing platform 1 so as to facilitate the subsequent battery changing operation on the vehicle. In an alternative situation, such as shown in fig. 1 to 4, the lifting mechanism described above may be provided with a front wheel lifting device 12 and a rear wheel lifting device 13, which are arranged at the front and rear part of the power conversion platform 1, respectively, for lifting the vehicle's height in corresponding contact with the front and rear wheels 60, 61 of the vehicle 6. In addition, the positioning operation of the vehicle on the battery changing platform 1 can also be realized by the front wheel lifting device 12 and the rear wheel lifting device 13.
In the above-mentioned power exchange platform 1, the vehicle can be exchanged by only removing the vehicle from the working surface of the power exchange platform 1 and reaching a preset height through a lifting mechanism, which is different from the mode that the existing power exchange station must lift the vehicle to a certain height so as to allow the RGV to travel to the space under the lifted vehicle for battery exchange. That is, the preset height may be a minimum height at which wheels of the vehicle are separated from the working surface of the battery changing platform 1 and battery attaching and detaching operations can be performed, for example, a distance at which the vehicle can be air-suspended, which can ensure that the vehicle does not move on the battery changing platform 1 by the self weight of the vehicle body when the battery of the vehicle is replaced. That is, after the vehicle 6 has been driven into position past the ramp 11 of the power conversion table 1, the vehicle 6 may simply be lifted slightly so that the wheels 60, 61 are clear of the working surface of the power conversion table 1, and a subsequent power conversion operation may be performed.
Therefore, the preset height is obviously smaller than the lifting height of the vehicle required by the existing power exchange station, so that the lifting formation time of the vehicle and the time consumption of the whole power exchange operation can be obviously shortened, the electric energy consumption during the power exchange period can be reduced, and the power exchange experience of a user can be improved. In practical application, the invention allows the preset height to be flexibly selected and set according to specific requirements and the conditions of the vehicle.
After the vehicle is lifted to the above-described preset height, the battery of the vehicle can be detached and operated by the detaching mechanism 14 provided in the battery changing platform 1, thereby completing the battery changing work. After the battery (e.g., a dead battery, a faulty battery, etc.) is removed from the vehicle by the dismounting mechanism 14, it can be transferred to the battery docking device 2 by the transfer mechanism 15 in the battery changing platform 1, which can then transfer the battery to the battery compartment 3 for storage, charging, etc. The transfer mechanism 15 may also receive a charged battery transferred from the battery docking device 2, such as a full battery from the battery compartment 3, and then transfer the charged battery to the vehicle 6 (e.g., below the vehicle) for subsequent mounting of the charged battery to the vehicle 6 by the dismounting mechanism 14.
In practical use, the above-described dismounting mechanism 14 and the conveying mechanism 15 may be integrally arranged together in one frame structure, and such a frame structure may be installed, for example, in the middle of the power exchanging platform 1 so as to correspond to a battery position that is usually installed in the bottom of a vehicle to facilitate a power exchanging operation.
The present power conversion system embodiment takes a completely different approach from the existing power conversion system in the transfer motion of the battery after the battery is removed from the vehicle, which can be seen by comparing fig. 5 and 6 to find a significant difference.
In the prior art power conversion system shown in fig. 5, it is apparent that such a rotation operation would take additional time for the vehicle battery removed from the power conversion platform by requiring a 90 degree turn as shown by the rotational arrow in the figure to be placed on the RGV and then transported by the RGV to the battery compartment.
For the present embodiment of the power exchanging system, after the battery is detached from the vehicle, it is possible to directly transfer it via the transfer mechanism 15, i.e. into the battery docking device 3 described in detail below, in the direction D1 indicated by the arrow in the figure, without any directional adjustment of the battery, but the latter is transferred to the battery compartment 3 for storing, charging, etc. Compared with the prior art shown in fig. 5, the power exchanging system does not need to implement additional battery rotation adjustment actions at all, so that the removal of the ring can effectively improve the power exchanging operation speed and increase the success rate of the power exchanging operation.
In an alternative case, the control unit 16 for controlling the power exchanging operation may be integrated into the power exchanging station 1, which will facilitate further optimization of the same spatial layout, form a more compact overall structure, and facilitate operational application.
In the embodiment given, it is exemplarily shown that the control unit 16 can be arranged at the rear of the power conversion platform 1, since in this embodiment a ramp 11 is provided for vehicles to drive in or out of the power conversion platform 1, i.e. vehicles will not drive into the rear area of the power conversion platform 1, which area can thus be exploited for arranging the control unit 16. Of course, in some embodiments, the control unit 16 may also be arranged at the side of the level shifter 1, for example, or in combination at any suitable location area at the rear, side, etc. of the level shifter 1.
It should be noted that in the prior art, the control cabinet and the level shifter are generally arranged independently, and such an arrangement is already common in the industry and has been used by those skilled in the art to be a standard mode in the industry. In contrast, in this embodiment, the control unit 16 having the same or similar function as the existing control cabinet is integrally disposed in the power conversion platform, which breaks through the conventional layout design, and makes the whole device structure layout more compact and attractive, and facilitates the installation of the device, the power conversion operation and the like to be quite convenient, fast, safe and reliable.
Referring to fig. 7 and 8, the basic structural composition of an example of the battery docking device in the above-described embodiment of the quick-change system is schematically shown by these two drawings.
In this example, the battery docking device 2 is arranged between the battery changing platform 1 and the battery compartment 3 for transferring batteries, and the battery changing platform 1 and the battery compartment 3 may be arranged on the left and right sides of the battery docking device 2 shown in fig. 1, respectively, which will facilitate forming a very compact overall layout, effectively improving space utilization.
As shown in fig. 7 and 8, the battery docking device 2 may include a lifting unit 22, a translation unit 23, and a battery relay unit 24. In the lifting unit 22, a lifting mechanism 221 is provided, which lifting mechanism 221 may be, for example, a scissor lift mechanism or any other suitable mechanism for lifting movement in a first direction D1 as indicated in fig. 7, which first direction D1 is perpendicular to the working surface of the power conversion platform 1 and is typically the vertical direction of the site of the quick power conversion 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 provides effective material savings, and may be manufactured efficiently by using various suitable processes, such as welding. Alternatively, the lifting mechanism 221 may be conveniently mounted directly to the frame structure of the lifting unit 22.
For the translation unit 23, it is connected to the lifting unit 22 in order to enable a translation movement of the lifting unit 22 in a second direction D2 as indicated in fig. 7, which second direction D2 is perpendicular to the above-mentioned first direction D1 and can be kept generally parallel to the longitudinal direction of the level shifter 1, as an option.
As an exemplary illustration, in an alternative case, the translation unit 23 may be fixed on a working surface of a site (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 at the bottom of the translation unit 23 as shown in fig. 8, and then the translation movement of the lifting unit 22 on the translation unit 23 may be achieved by a fitting member (e.g., a slider, a guide rail wheel, etc., which may be installed in the linear guide rail) that may be provided on the lifting unit 22, and the battery transfer unit 24 may be brought to a suitable position associated with the battery exchange platform 1 or the battery compartment 3, 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 elevation unit 22 to provide power for controlling the translational movement of the mating member on the elevation unit 22 along the guide member 231 on the translation unit 23. Furthermore, in the alternative, the lifting unit 22 and the translation unit 23 can be arranged to run synchronously, which is highly advantageous in that the above-described translation movement and lifting movement can be performed simultaneously or substantially simultaneously as desired, whereby these respective operating process times can be saved considerably.
For the battery relay unit 24, it is connected to a lifting mechanism 221 in the lifting unit 22, so that lifting movement can be performed by means of the lifting mechanism 221, whereby a suitable position associated with the battery changing platform 1 or the battery compartment 3 is reached for battery transfer. In particular, as shown in fig. 7, for example, the battery relay unit 24 may be installed in the frame structure of the elevation unit 22 and connected with the elevation mechanism 221 also disposed in the frame structure, so that the battery relay unit 24 is integrated into the frame structure of the elevation unit 22 in a similar combination, which effectively improves space utilization and significantly reduces the overall occupation space of the apparatus.
In addition, according to the actual application requirement, the battery transfer unit 24 may be configured to have one or more battery bins, so that the battery (e.g., a power-deficient battery, a faulty battery, etc.) detached from the vehicle parked on the level shifter 1 may be stored in the battery bins, so that the battery may be subsequently transferred and stored in the battery bin 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 exchange platform 1 by the battery docking device 2 for loading onto a vehicle parked on the battery exchange platform 1 for battery exchange.
In an alternative case, the battery docking device 2 may be arranged 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 discharged battery from the vehicle located on the battery exchange platform 1, for example, such that the height of the battery compartment at this time is the same or substantially the same as the height at which the discharged battery is ready to be transferred from the battery exchange platform 1 outward toward the battery docking device 2, which may effectively save the corresponding operation processing time, contributing to further improving the overall battery exchange efficiency and success rate. In the example of the battery docking apparatus given, as shown in fig. 9 and 10, the battery relay unit 24 is exemplarily shown as having a two-layered battery compartment structure, i.e., an upper-layered battery compartment 241 and a lower-layered battery compartment 242, for example, the battery 6 currently stored in the lower-layered battery compartment 242 is shown at the same time in fig. 10. In particular applications, one of the upper battery bay 241 and the lower battery bay 242 may be used to store batteries removed from a vehicle parked on the battery bay 1 (which is to be transferred to the battery bay 3 for storage, charging, etc.), and the other to store rechargeable batteries removed from the battery bay 3 (which is to be transferred to the battery bay 1 and loaded onto the vehicle), for example, the upper battery bay 241 may be used to store rechargeable batteries and the lower battery bay 242 may be used to store depleted batteries.
It should be appreciated that the battery relay unit 24 may be constructed to have three, four or more battery compartments that are to be stacked in the first direction D1 so that a greater number of batteries detached from the vehicle, and charged batteries removed from the battery compartment 3, may be stored, which may contribute to effectively improving the working efficiency of the power exchanging operation, without departing from the gist of the present invention. Of course, the present invention also allows the battery bins of the battery relay unit 24 to be arranged in parallel, or a part of them to be stacked while being arranged in parallel, so as to better satisfy various possible practical application requirements.
For the existing power exchanging systems, when the power exchanging operation is performed, generally, after the power-deficient battery detached from the vehicle is conveyed to a designated bin of the battery bin by the AGV, a piece of charged battery is taken out from other bins of the battery bin for exchanging the battery to the vehicle, and the RGV will travel relatively long conveying distance in the process, thus consuming more time. In contrast, by applying the battery docking apparatus 2 as described above, a plurality of battery bins can be used to store a plurality of batteries (such as charged batteries, dead batteries, faulty batteries, etc.), thereby significantly reducing the number of trips between the battery changing platform and the battery bins, and thus greatly improving the battery changing efficiency and reducing the time required for battery changing.
Further, in the alternative, at least one transfer member 240 (e.g., conveyor belt, roller, etc.) may be provided in one or more battery compartments in the battery relay unit 24, such as one transfer member 240 each at the front and rear of the battery compartment of the battery relay unit 24 as shown in fig. 5. By means of such a transfer member 240, the batteries can be moved in or out of the battery compartment in the third direction D3 as indicated in fig. 7, since the third direction D3 is kept parallel to the battery access direction in the battery compartment 3 and the battery transfer arrangement direction of the transfer mechanism 15, as previously described, this is not necessary at all for adjusting the battery transfer directions when transferring the batteries between the battery compartment 3 and the battery compartment of the battery transfer unit 24, whereby the time consumption in the battery transfer link can be significantly reduced, further improving the efficiency of the battery change operation.
In an alternative scenario, a vehicle carrying assembly may be provided in the quick change system embodiment discussed above for carrying the vehicle during a vehicle change without any leveling operation. With reference to fig. 11 to 14, the basic structural composition of the two load bearing devices in one example of a vehicle load bearing assembly, by means of which the vehicle load bearing assembly can be composed and which can be mounted to a power conversion platform for achieving the above-described functions of the vehicle load bearing assembly, and their respective two operating states (i.e. an unloaded state in which no load bearing is required and a loaded state in which load bearing is required) are exemplarily provided in the following.
Specifically, in this example shown in fig. 11 and 12, the carrier 17 includes a base 171, a receiving portion 172, and a power member (not shown), the carrier 17 is schematically shown in an unloaded state in fig. 11, and the carrier 17 is schematically shown in a loaded state in fig. 12.
For the base 171, it is mounted to a level shifter 1, such as shown in fig. 13 and 14, for providing support to the entire carrier 17. For example, the base 171 may be vertically mounted to the power conversion platform 1. In alternative cases, the base 171 may be configured in a column (e.g., circular post, square post, etc.), or it 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, and may be connected to each other by, for example, hinge, welding, or the like. The receptacle 172 is configured to contact the vehicle to carry its weight during a power change, and may be configured in a rod shape or any other suitable shape depending on the particular application.
In the carrier 17, the power means are arranged to provide power so that the above-mentioned receptacle 172 can move in a horizontal plane relative to the base 171 and form a self-lock when moved into position (i.e. to a desired position). By performing the above-described movement, the state of the carrier 17 can be switched between the unloaded state and the loaded state, and the above-described self-locking function is provided, so that an unexpected problem such as the occurrence of the shaking of the receiving portion 172 when the vehicle is carried can be avoided.
By way of example, the power components described above may employ a motor, and the base 171 may be configured to have an internal cavity for placement of the motor therein, so that the carrier may have a very compact structure. In addition, since the load-bearing device 17 is not required to bear the load of the vehicle during the switching between the idle state and the load-bearing state, the motor with smaller power can be used for driving, which is also beneficial to reducing the occupied space of the motor. Of course, in some applications, other components, units, devices, etc. may be used as the power component, and for example, a speed increasing mechanism, a speed reducing mechanism, etc. may be provided.
As shown in fig. 11, in the unloaded state of the carrier 17, the abutment 172 and the base 171 can be formed at an angle (e.g., 90 degrees or other suitable value) such that they are not loaded. When powered by a power component such as a motor, the carriage 172 may be rotated in a horizontal plane through an angle (e.g., 90 degrees or other suitable value) relative to the base 171 to a desired position where the load carrying device 17 is in the load carrying condition shown in fig. 12, i.e., where the load carrying device 17 may be used to carry a vehicle load.
Next, referring again to fig. 13 and 14, another load bearing apparatus that may be used in a vehicle load bearing assembly is shown by way of illustration and will be described in detail.
In this example, the carrier 17 includes a base 171, a socket 172, and a power component (not shown), the carrier 17 being schematically illustrated in fig. 13 in an unloaded state, and the carrier 17 being schematically illustrated in fig. 14 in a loaded state. The corresponding description of the carrier arrangement shown in fig. 11 and 12 in terms of structure, composition, mounting arrangement, function etc. applies equally to the carrier arrangement shown in fig. 13 and 14, unless otherwise specified herein.
Unlike the previously described carriers, with the carrier 17 shown in fig. 13 and 14, an angle (e.g., 90 degrees or other suitable value) may be formed between the bolster 172 and the base 171 when it is in an unloaded state; when powered by a power unit such as a motor or the like, the receiver 172 can be rotated in a vertical plane through an angle (e.g., 90 degrees or other suitable value) relative to the base 171 to a desired position, i.e., to place the load bearing device 17 in the load bearing condition shown in fig. 14, so that the load bearing device 17 can be used to bear a vehicle load.
The two types of load bearing apparatuses have been described above by way of example only, either or both of which may be used to form a vehicle load bearing assembly in a quick-change system of the present invention.
In particular, in practical applications, the vehicle carrying assembly may include two or more such carrying devices, which may be installed and arranged at any suitable position on the power exchanging platform, and may be initially assembled such that the level difference between the carrying devices when in the carrying state is controlled within a preset range (the specific difference accuracy requirement may be set according to the practical application), so that it is ensured that when the vehicle to be power exchanged is placed on the carrying devices of the vehicle carrying assembly, the level standard required for the power exchanging operation using the dismounting mechanism can be fully achieved, and thus, as in the prior art, multiple leveling operations are not necessary before the power exchanging operation. Therefore, equipment cost of configuring a motor-screw rod transmission mechanism, a control program and the like can be saved, the power changing time can be obviously reduced due to the fact that the leveling operation process is canceled, the whole operation is simplified, the use and maintenance cost is reduced, and the power changing efficiency and the success rate can be improved.
It will be appreciated that employing the above-described vehicle load bearing assembly has these very significant technical advantages as discussed above, as compared to the prior art. The levelness difference/error only exists in the machining precision and the initial assembly of the bearing devices at one time, 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 perform operations such as maintenance, replacement, etc. on certain load-bearing devices of the vehicle load-bearing assembly, and at this time, adjustment and control can also be performed with respect to the level difference/error between these load-bearing devices, so as to enable them to continue to conform to the required level standard, thus eliminating the need for leveling operations that are common and necessary in the prior art.
In addition, since the present invention employs innovative improvements such as those described above, it is not necessary to provide a power-exchanging running gear such as the RGV of the prior art, and thus a series of components such as running motor, rack and pinion, bearings, wheels, rails, etc. can be eliminated, resulting in saving in manufacturing, assembly and maintenance costs. In addition, since the RGV generally has a high height, in order to secure the in-out of the battery, an operation space is required to be provided after the vehicle is lifted to a certain height on the battery exchange platform, which also results in that the driver must leave the vehicle to allow the operation, and in the existing battery exchange system, a leveling operation is required in advance to secure the accuracy of the battery assembling and disassembling operation, and if the driver is always located in the vehicle during the battery exchange operation, the movement of the driver in the vehicle may adversely or even seriously affect the battery assembling and disassembling operation. By contrast, by adopting the technical scheme of the invention, the leveling operation of the vehicle is not needed before the power change operation, so that a driver and a passenger do not need to leave the vehicle during the power change operation, the time consumption of the power change operation can be greatly optimized, and the power change use experience of a user can be obviously improved.
Furthermore, it should be noted that, without departing from the gist of the present invention, the specific structural composition, construction form, material, number of arrangements, etc. of the carrying device in the vehicle carrying assembly are allowed to be flexibly designed, changed and adapted according to the design concept of the present invention so as to be able to fully meet the various possible practical application requirements.
As an example, as shown in fig. 1 and 2, two or more carrying devices 17 of the type shown in fig. 11 and 12 may be mounted on one side of the exchange platform 1 (e.g. on the side closer to the battery interface 2), which carrying devices 17 may be arranged in the direction shown in fig. 1 without bearing load when in an empty state, i.e. such that the receptacles 172 of the carrying devices 17 remain parallel to the longitudinal direction of the vehicle body direction/exchange platform 1. When it is desired to have it in a loaded condition, the power may be provided by a power means, such as a motor or the like, such that the receptacle 172 in the carrier 17 is rotated in a horizontal plane by an angle (e.g. 90 degrees or other suitable value) with respect to the base 171 to a desired position and to create a self-lock for subsequent use in carrying the load of the vehicle 6 to be replaced.
As another example, as shown in fig. 15 and 16, while two or more carrying devices 17 of the type shown in fig. 11 and 12 are mounted on one side of the power conversion platform 1 (i.e., the left side in fig. 15 and 16), two or more carrying devices 17 of the type shown in fig. 13 and 14 may be mounted on the other side of the power conversion platform 1 (i.e., the right side in fig. 15 and 16), and these carrying devices 17 may be arranged in the direction shown in fig. 15 without bearing a load when in an empty state. When it is desired to put it in a loaded state, the power may be supplied by a power member such as a motor or the like such that the receiving portion 172 in the loading device 17 is rotated by an angle (e.g., 90 degrees or other suitable value) in a vertical plane with respect to the base portion 171, reaches a desired position as shown in fig. 16 and becomes self-locking so as to be subsequently used to carry the load of the vehicle 6 to be replaced.
As shown in fig. 15 and 16, in alternative cases, a carrier 17 of the type shown in fig. 13 and 14, respectively, may be arranged in the vicinity of the front wheel lift 12 and the rear wheel lift 13, which not only results in a more compact overall construction layout, but also facilitates a better distribution and application of the carrier forces to suitable locations on, for example, the chassis of the vehicle.
In addition, in an alternative case, the charging device in the battery storage and transportation assembly of the quick power change system of the present invention may be externally arranged and then connected to the charging connector in the battery compartment 3 through a cable for charging the battery stored in the battery compartment 3. The charging device is large in general working power and large in heating value, so that heat generation and accumulation in the installation space of the quick power change system can be effectively reduced by adopting the arrangement mode, and the charging device is beneficial to providing more ideal personnel working environment and equipment operation environment.
Of course, with the control cabinet 5 for controlling the battery compartment 3, for example, it can be arranged in a quick-change system without being externally arranged because of its small heat generation amount.
In addition, in order to effectively control the heat generated and accumulated at the battery compartment 3, a cooling device 4 may be disposed in a vacant space such as the bottom of the battery compartment 3, which may be used not only for cooling the battery stored in the battery compartment 3, but also for further fully utilizing the system space. For the above cooling device, for example, a respective water cooling device, an air cooling device, or the like may be employed 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 delivery assembly of the quick-change system according to specific requirements, so that the system of the present invention can be well adapted to various application environments.
By way of example, the battery compartment 3 may be provided to include one or more identical battery compartment units, and these battery compartment units may be arranged side-by-side, such as is illustrated schematically in fig. 17, two battery compartment units may be arranged side-by-side together to provide greater battery storage capacity. For each battery compartment unit, it may be configured to have N layers, and each layer has M battery compartments, and the above two parameters N and M may be the same or different positive integers. Of course, the invention also allows the battery compartment 3 to comprise two or more different battery compartment units, i.e. they may have different structural designs, and the respective battery storage capacities may be flexibly selected, changed and adapted according to the needs of various practical applications.
It should also be noted that, according to the technical solution of the present invention, it is also conceivable to add a battery storage assembly in some application embodiments, which may have exactly the same, substantially the same or similar composition as the battery storage assembly as described above. Under the condition that the field space allows, the two battery storage and transportation components can be respectively arranged at the two sides of the battery replacement platform 1, so that the battery storage capacity and the charging processing capacity of the quick battery replacement system can be increased by times, the battery storage, transfer and replacement operation efficiency can be further improved, the whole battery replacement time is shortened, and the system has stronger adaptability, flexibility and expansibility. In addition, as an aspect that is significantly superior to the prior art, the present invention also provides a quick power change method. As an example, as shown in fig. 18, the quick power change method may include the steps of:
In step S11, a quick power conversion system designed and provided according to the present invention is provided;
in step S12, a vehicle is driven into and stopped on a power exchange platform in the quick power exchange system, and then the vehicle can be lifted to a preset height by a lifting mechanism of the power exchange platform so as to perform battery disassembly and assembly operations on the vehicle;
in step S13, the battery interface in the fast battery change system (e.g., the battery interface in the battery storage assembly on one side of the battery change table and/or the battery interface in the battery storage assembly on the other side of the battery change table) may be used to transfer the battery between the battery compartment and the battery change table. Regarding the above battery transfer, transfer and access operations, since the description has been made in great detail in the foregoing exemplary description of the quick-change system, reference may be made directly to the detailed description of the corresponding portions thereof, and the description and discussion thereof will not be repeated herein; and
in step S14, after the battery assembling and disassembling operation is completed on the vehicle, the vehicle may be lowered onto the power conversion platform by the lifting mechanism of the power conversion platform, and then the vehicle is driven away from the power conversion platform, so as to end the power conversion operation of the vehicle.
Of course, it should be noted that some operations in the above steps S12 and S13 may not necessarily be performed sequentially, e.g., some operations in step S13 may occur before or after some operations in step S12, or it may be possible to perform them synchronously or substantially synchronously.
For example, while the battery (commonly referred to as "battery-starved") is removed from the vehicle that is parked on the battery-exchange platform, some battery-access transfer operations may be performed simultaneously, so that the overall battery-exchange time may be significantly shortened, and the battery-access operation efficiency may be greatly improved. For example, the charged battery may be moved from the battery bay of the battery compartment into the battery bay of the battery docking device (e.g., the upper battery bay located in the battery transfer unit) at this time. For another example, the battery docking device may be brought into position at this time to wait for the battery removed from the vehicle to be moved from the battery dock into its battery bay, and then the charged battery is transferred from the battery docking device to the battery dock. Also for example, in connection with the example of the quick change system discussed above, the lifting unit and the battery transfer unit of the battery docking device may be translated together to the battery compartment of the battery compartment where the rechargeable battery is located, and at the same time the battery transfer unit is lifted in the vertical direction to the battery compartment of the battery compartment where the rechargeable battery is located, so as to obtain the rechargeable battery and then transferred to the battery change platform through the battery docking device.
For another example, while the rechargeable battery is loaded to the vehicle parked on the power conversion platform, some battery access transfer operations can be synchronously executed, so that the battery access operation efficiency is also obviously improved, and the overall power conversion time is obviously shortened. For example, the battery removed from the vehicle may now be transferred from the battery change station towards the battery compartment using the battery docking device in order to finally move it into the battery compartment of the battery compartment. More specifically, in connection with the quick change system example discussed above, the lifting unit and the battery transfer unit of the battery docking apparatus may be translated together to an empty battery bay of the battery compartment and at the same time the battery transfer unit is lifted in a vertical direction to the battery bay so that the removed battery may be moved into the battery bay.
By adopting the above or similar operation modes, two or more operations (such as translation operation and/or lifting operation of the battery connection device, battery dismounting operation of a vehicle parked on the battery exchange platform, various possible operations of two or more batteries in two battery storage and transportation assemblies positioned on two sides of the battery exchange platform at the same time and the like) can be synchronously or basically synchronously executed, so that the time consumption of the battery exchange operation in some intermediate links can be effectively overlapped, and the overall efficiency of operations such as battery transfer, storage and the like is remarkably improved.
The fast power-changing system and the fast power-changing method according to the present invention have been described in detail by way of example only, and these examples are provided only for illustrating the principle of the present invention and its embodiments, and not for limiting the present invention, and various modifications and improvements may be made by those skilled in the art without departing from the spirit and scope of the present invention. Accordingly, all equivalent arrangements should be considered to be within the scope of the present invention and as defined in the claims.
