For those skilled in the art, the specific meanings of the above terms in the present utility model can be understood according to specific situations.

Referring first to Fig. 1, Fig. 1 is a schematic diagram of the structure of the charging and swapping station of the present invention. As shown in FIG. 1 , the charging and swapping station of the present invention mainly includes a battery swapping platform 1 , a storage unit 2 , a charging unit 3 and an automatic battery swapping robot 4 . The battery exchange platform 1 is used to park the electric vehicle 5 to be exchanged, and the storage unit 2 includes several battery storage units 21. The power battery 6 (hereinafter referred to as a power-deficient battery), and the charging unit 3 is used to charge the power battery 6 stored on the battery storage unit 21 . The automatic battery-swapping robot 4 can at least move freely within the range between the battery-swapping platform 1 and the storage unit 2 , such as linear motion and in-situ rotation on the ground between the battery-swapping platform 1 and the storage unit 2 . On the basis of this movement, the automatic battery replacement robot 4 can complete the action of replacing the power battery 6 for the electric vehicle 5 to be replaced. For example, when the automatic battery replacement robot 4 is in the projection position of any battery storage unit 21, the automatic battery replacement robot 4 can directly accept a fully charged battery from the battery storage unit 21 or fix a power-deficient battery on the battery storage unit 21; When the automatic battery replacement robot 4 is in the projected position of the electric vehicle 5 to be replaced, the automatic battery replacement robot 4 can complete the unloading of the exhausted battery from the electric vehicle 5 to be replaced or fix the fully charged battery to the electric vehicle 5 action on.

First of all, it needs to be explained that the fully charged battery and the deficient battery in this embodiment are only used to describe the macro state of the power battery 6, not to describe the two special fixed states of the power battery 6, that is, the power is in a state of 100%. and the state of zero power. Those skilled in the art can imagine that the division basis of "full power" and "deficient power" can be freely set by the service provider, such as taking the remaining power not less than 90% of the total power as the "full power" of the power battery 6. Electricity" standard, the remaining power is less than 90% of the total power as the standard of "deficiency" of the power battery 6, etc.

It can be seen from the above that by setting the freely movable automatic battery-swapping robot 4 between the battery-swapping platform 1 and the storage unit 2, the automatic battery-swapping robot 4 can replace the electric vehicle 5 to be battery-swapped without leaving the ground. Replace the power battery 6. In other words, the movement and positioning of the automatic battery-swapping robot 4 does not require the use of guide rails, and the process of picking up and delivering the battery does not require multiple lifts. It not only greatly simplifies the structure of the battery swap station, but also reduces the design complexity of the battery swap station—that is, it simplifies the setting of the guide rail, lifter module, and fine positioning mechanism on the battery swap platform 1, so that the charging station The battery swapping station can more efficiently complete the action of replacing the power battery 6 for the electric vehicle 5 to be swapped, greatly improving the user's battery swapping experience.

The charging and swapping station of the present invention will be further described below with reference to FIG. 2 and FIG. 3 . Among them, FIG. 2 is a schematic structural diagram of the automatic battery swapping robot 4 of the present invention, and FIG. 3 is a schematic bottom view of the charging and swapping station of the present invention.

As shown in FIG. 2 , the automatic battery swapping robot 4 mainly includes a main body 41 , a walking part 42 , a battery loading and unloading part, a positioning part (not shown in the figure), a control part 44 and the like. Among them, the walking part 42 can move the automatic battery swapping robot 4 on the ground between the battery swapping platform 1 and the storage part 2 through its own rolling, such as using a mecanum wheel, differential wheel or steering wheel as the walking part 42 to realize automatic The rectilinear motion and in-situ rotation etc. of battery-changing robot 4 on the ground. The positioning unit can at least obtain the relative position of the current position of the automatic battery-swapping robot 4 and the electric vehicle 5 or the battery storage unit 21 to be replaced, for example, the positioning unit can obtain the current position of the automatic battery-swapping robot 4 and the electric vehicle to be replaced. 5 or the relative position between the fully charged batteries of the battery storage unit 21. The control unit 44 can control the movement of the walking unit 42 based on the relative position, so that the automatic battery swapping robot 4 can accurately arrive at the projected position of the deficient battery or the fully charged battery, and then when the projected position is reached, the control unit 44 controls the battery loading and unloading unit Replace the power battery 6 for the electric vehicle 5 to be replaced or receive a fully charged battery from the battery storage unit 21 .

The battery loading and unloading part further includes an locking and unlocking mechanism 432 and a lifting platform 431 . Wherein, the lifting platform 431 can complete the docking with the battery storage unit 21 or the electric vehicle 5 through the lifting action, such as reaching the position where the battery with a power loss can be fixed on the battery storage unit 21, or accepting the battery storage unit 21 when the battery storage unit 21 is fully charged. The position of the electric battery, and the position where the power battery 6 is replaced for the electric vehicle 5, etc. Adding the unlocking mechanism 432 can make the power battery 6 lock/unlock the body of the electric vehicle 5 after the lifting platform 431 reaches the position for replacing the power battery 6 for the electric vehicle 5 . Preferably, the lifting platform 431 can be driven by a scissor lift mechanism, and the scissor lift mechanism can lift the lifting platform 431 together with the power battery 6 on the lifting platform 431 until reaching the replacement of the power battery 6 for the electric vehicle 5 s position.

Further preferably, in order to facilitate the manufacture of the automatic battery-swapping robot 4 and save the manufacturing cost of the automatic battery-swapping robot 4, the automatic battery-swapping robot 4 of the present utility model can be transformed based on an existing automatic guided vehicle (Automatic Guided Vehicle, AGV) . For example, on the basis of the existing automatic guided vehicle, retain its body and walking part, increase the positioning part and battery loading and unloading part, and upgrade the function of the original control part of the automatic guided vehicle, so that the control part of the automatic battery replacement robot 44 It can form a control closed loop with the walking part and the positioning part, that is, the aforementioned "controlling the movement of the walking part 42 based on the relative position, so that the automatic battery replacement robot 4 can accurately reach the projected position of the deficient battery or the fully charged battery", thus saving both Manufacturing cost, can realize the utility model again.

Further preferably, since the movement of the automatic battery-swapping robot 4 does not require the restriction of guide rails, the function of the automatic battery-swapping robot 4 in terms of battery-swapping safety can also be expanded. For example, the automatic battery-swapping robot 4 can also be driven by the walking part 42 to reach The preset emergency position in the charging and swapping station. That is to say, in addition to the position of the normal power exchange process, a temporary processing position for the power battery 6 when an emergency situation occurs is used for the automatic power exchange robot 4 to transport the power battery 6 in an abnormal state to this position in time, In order to deal with the power battery 6 in an abnormal state in time. For example, if an emergency position is set in a relatively safe position of the charging and swapping station, and the emergency position is equipped with an emergency sandbox for isolating the power battery 6, when the system or service personnel detect that a certain power battery 6 is in an abnormal state , the automatic battery replacement robot 4 can transport the power battery 6 in an abnormal state to the emergency sandbox in time under the control of the control unit 44 or the operator, so as to isolate the battery in an abnormal state and avoid causing damage to the charging and replacing station. unpredictable consequences.

As mentioned above, through the setting of the automatic battery-swapping robot 4 in the above-mentioned charging-swapping station, that is, the setting of the automatic battery-swapping robot 4 that can move freely and be accurately positioned, not only can the movement flexibility of the automatic battery-swapping robot 4 be greatly improved, Improve the efficiency of battery swapping, and also simplify the design of the fine positioning mechanism on the battery swapping platform 1 and the laying of guide rails between the battery swapping platform 1 and the storage unit 2, so as to realize the structural optimization of the charging and swapping station. In addition, due to the trackless arrangement of the automatic battery-swapping robot 4 , the safety function of the automatic battery-swapping robot 4 can also be expanded, and the safety of the charging and swapping station can be improved.

Those skilled in the art can also understand that the arrangement of the above-mentioned automatic battery exchange robot 4 is only used to illustrate the principle of the utility model, and is not intended to limit the scope of protection of the utility model, without departing from the principle of the utility model Under the premise, any automatic battery-swapping robot 4 that can move freely and be precisely positioned will fall into the protection scope of the present invention.

As shown in Figure 3, the battery swapping platform 1 can be arranged on one side of the charging and swapping station, and it mainly guides the vehicle into the platform, and performs simple rough positioning and lifting functions for the vehicle. For example, V-shaped rollers and other components are used to complete the rough positioning of the vehicle, and components such as lifting motors, reels, pulleys, and wire ropes are used to complete the lifting of the battery exchange platform 1. The projected position of the electric vehicle 5 and the precise positioning are carried out for bottom battery replacement. According to the orientation shown in FIG. 3 , the battery swapping platform 1 is set at the leftmost position of the charging and swapping station next to the storage unit 2 , that is, the position where the electric vehicle 5 is parked in the figure.

The advantage of such an arrangement is that the power exchange platform 1 arranged on the leftmost side can save space to the greatest extent, so that the remaining space can be allocated to the storage unit 2 as a whole. The way of setting up next to the storage unit 2 shortens the moving distance of the automatic battery swapping robot 4 between the battery swapping platform 1 and the storage unit 2, that is, it can save the moving time of the automatic battery swapping robot 4 during the battery swapping process, and improve power exchange efficiency. Furthermore, since the battery exchange platform 1 does not need precise positioning (because the fine positioning is mainly completed by the automatic battery exchange robot 4), this setting method also greatly reduces the difficulty of designing the battery exchange platform 1 and simplifies the process of charging and replacing. The overall design of the power station and the maintenance of the parking platform are conducive to the product standardization of the power exchange platform 1.

Of course, the arrangement position and setting method of the power exchange platform 1 are not limited to this, and those skilled in the art can make flexible adjustments based on the specific application environment. For example, the power exchange platform 1 can also be arranged in the middle or any position of the power exchange station. The power exchange platform 1 can be fixed at a certain height without lifting, and has a slope to guide the electric vehicle 5 into the platform, or the power exchange platform 1 It is installed on the ground floor, and the battery replacement trolley can perform battery replacement work underground.

Referring to FIG. 1 and FIG. 3 , the storage unit 2 includes several battery storage units 21 arranged in a set manner. Preferably, the battery storage unit 21 is arranged in a planar stacking manner, that is, the power batteries 6 corresponding to the battery storage unit 21 are stacked on the same layer, instead of the three-dimensional stacking in the background art. The lower side of the battery storage unit 21 is provided with a clamping mechanism 211 (refer to FIG. 1 ). The clamping mechanism 211 can fix or disengage the power battery 6 from the battery storage unit 21 by clamping or loosening. Preferably, one battery storage unit 21 can store one battery, and the battery storage unit 21 is configured in a modular manner. That is to say, the battery storage units 21 can operate independently of each other without interfering with each other, and can be expanded arbitrarily according to different site selection environments and power supply capacities without affecting other battery storage modules.

Further preferably, in terms of arrangement, the battery storage units 21 can be arranged with the highest efficiency (that is, arranged with the highest space utilization). Taking the charging and swapping station shown in FIG. 3 including six battery storage units 21 as an example, the method for arranging them with the highest efficiency will be described in detail below.

As shown in Figure 3, the method for the highest efficiency arrangement mainly includes the following steps:

1) Obtain the length L _B and width W _B of the battery storage unit 21 , and the length L _S and width W _S of the area of the storage part 2 .

2) Calculate separately as well as the result of. in For rounding down operation.

3) calculate and results and compare the results.

i) if Then the length direction of the battery storage unit 21 is arranged perpendicular to the length direction of the storage part 2 area, and arranged in the length direction of the storage part 2 A battery storage unit 21 (power battery 6), arranged in the width direction of the storage part 2 A battery storage unit 21 (power battery 6).

ii) Otherwise, the length direction of the battery storage unit 21 is set in parallel with the length direction of the storage part 2 area, and arranged in the length direction of the storage part 2 a battery storage unit 21 arranged in the width direction of the storage part 2 A battery storage unit 21.

For example, assume that in Figure 3:

The length L _S of storage part 2 area is 5000mm (being the length of vertical direction);

The width WS of the storage part 2 area is _4600mm (ie the length in the horizontal direction);

The length L _B of the battery storage unit 21 is 2100mm;

The width W _B of the battery storage unit 21 is 1600 mm. but

and then

so

Choose to arrange the length direction of the battery storage unit 21 in a vertical manner to the length direction of the storage part 2 area, that is, the arrangement shown in Figure 3, and arrange three battery storage units 21 (three One power battery 6), two battery storage units 21 (two power batteries 6) are arranged in the width direction of the storage part 2.

The advantage brought by the above arrangement method is that the modular arrangement of the storage unit 2 allows the storage unit 2 of the charging and swapping station to be adjusted arbitrarily based on the application scenario, and the arrangement of the storage unit 2 in a plane stack makes the automatic battery exchange robot 4. No need to ascend or descend, only need to move on the ground to complete the action of fetching and delivering the power battery 6 and changing the electricity for the electric vehicle 5. That is to say, the above-mentioned setting method increases the layout flexibility and scope of application of the charging and swapping station, reduces the influence of the site selection environment and power supply capacity on the design and construction of the charging and swapping station, and thus simplifies the lifting and lowering of the charging and swapping station. The setting of the module reduces the construction cost of the charging and swapping station, and greatly reduces the difficulty of designing the charging and swapping station. By arranging the battery storage units 21 with the highest efficiency, the movement flexibility of the automatic battery replacement robot 4 is utilized to the greatest extent, and the space in the layout area is fully utilized, so that the space utilization rate under the same site selection environment reaches 100%. maximum.

It should be pointed out that the arrangement of the above-mentioned storage unit 2 and the arrangement of the battery storage unit 21 are only used to explain the principle of the utility model, and are not intended to limit the scope of protection of the utility model. Any form of adjustment is made to the above arrangement, so that the utility model can adapt to more specific application scenarios.

Wherein, the charging module 311 provides an electrical circuit, and the electrical circuit is mainly used for charging the exhausted battery fixed in the battery storage unit 21 . The water cooling module 313 provides a water cooling circuit, and the water cooling circuit is mainly used to cool the battery that is being charged, so as to prevent the power battery 6 from overheating. The control module 312 is mainly used to control the operation of the charging module 311 and the water cooling module 313 , and the control module 312 can also be used to control the clamping or loosening of the clamping mechanism 211 . Preferably, the number of charging units 31 may be equal to the number of battery storage units 21 , and each charging unit 31 is connected to one battery storage unit 21 . That is to say, the charging unit 31 is also arranged in a modular manner, and each charging unit 31 corresponds to a battery storage module, and provides the above-mentioned electrical circuit, water cooling circuit and sends corresponding control instructions/signals for the corresponding battery storage module.

The advantage of the above-mentioned distributed arrangement is that by setting a plurality of charging units 31, each battery storage unit 21 is equipped with an independent charging unit 31, so that the charging unit 31 and the battery storage unit 21 can form a The complete independent module is more conducive to the modular management of the charging and swapping station, and also makes the arrangement of the storage unit 2 more flexible, and the scalability of the charging and swapping station is better.

Of course, the arrangement of the battery storage units 21 is not static, and those skilled in the art can make adjustments to adapt to more specific application scenarios without departing from the principles of the present invention. For example, the arrangement of the battery storage unit 21 can also be arranged above the storage unit 2 in a centralized arrangement as shown in FIG. 4B , and be electrically connected to the storage unit 2 . In this setting mode, the charging part 3 can include a charging unit 31, and the charging unit 31 includes a charging cabinet 314, a control cabinet 315 and a water cooler 316, and the charging cabinet 314, the control cabinet 315 and the water cooler 316 of the charging unit 31 It is respectively connected to each battery storage unit 21 in the storage unit 2 . Of course, a combination of centralized and distributed arrangement can also be adopted. For example, the charging unit 3 includes several charging units 31, and some of the several charging units 31 are centralized charging units connected to a plurality of battery storage units 21 respectively. arrangement, while the other charging units 31 are in a distributed arrangement connected to the corresponding battery storage units 21 in a one-to-one correspondence.

Obviously, in order to realize the fully automatic power exchange of the charging and swapping station, the charging and swapping station also needs to be equipped with a main control unit, and the main control unit of the charging and swapping station, the control part 44 of the automatic battery changing robot 4 and the control module 312 of the charging part 3 ( The control cabinets 315) can communicate with each other, so as to cooperate to complete the coherent battery replacement action. For example, under the overall control of the main control unit, the automatic battery swapping robot 4 can complete the action of picking up and delivering the power battery 6 from the battery storage unit 21 , and complete the action of replacing the power battery 6 on the battery swapping platform 1 .

The working principle of the charging and swapping station of the present invention will be briefly described below with reference to FIG. 5 and FIG. 6A to FIG. 6D . Among them, Fig. 5 is a schematic flow diagram of the method for changing electricity in the charging and changing station of the present invention; Fig. 6A is a schematic flow diagram (1) of a complete battery changing process of the charging and changing station of the present utility model; A schematic flow chart (two) of a complete battery exchange process of the new charging and exchange station; Figure 6C is a schematic flow chart (three) of a complete battery exchange process of the charging and exchange station of the present invention; Schematic diagram of a complete battery swapping process of a new type of charging and swapping station (4).

As shown in Fig. 5, the utility model also provides a battery replacement method of a charging and replacement station, the battery replacement method mainly includes the following steps:

S100, the electric vehicle 5 to be replaced arrives at the battery replacement platform 1. For example, the electric vehicle 5 to be replaced is roughly positioned on the replacement platform 1 through the V-shaped roller, and the lifting of the replacement platform 1 is completed by using elevators, reels, pulleys, and wire ropes;

S200. The automatic battery swap robot 4 arrives at the projected position of the vehicle to be swapped. For example, under the control of the control unit 44 and the continuous positioning of the positioning unit, the automatic battery replacement robot 4 accurately reaches the projected position of the power-deficient battery on the electric vehicle 5 to be replaced through the linear motion and in-situ rotation of the walking part 42;

S300. The automatic battery swapping robot 4 separates the power-deficient battery from the vehicle to be swapped. For example, the automatic battery replacement robot 4 unloads the power-deficient battery from the electric vehicle 5 through the lifting of the lifting platform 431 and the unlocking action of the unlocking mechanism 432, and loads it on the lifting platform 431;

S400, the automatic battery replacement robot 4 fixes the exhausted battery to the battery storage unit 21 in an idle state without leaving the ground. For example, the automatic battery replacement robot 4 moves to the battery storage unit 21 in an idle state after removing the power-deficient battery, and after precise positioning with the battery storage unit 21, fixes the power-depleted battery to the clamping mechanism of the battery storage unit 21 211 on;

S500. The automatic battery swapping robot 4 receives the fully charged battery from the battery storage unit 21 storing the fully charged battery in a manner that does not leave the ground. For example, after the automatic battery replacement robot 4 moves to the projected position of the battery storage unit 21 loaded with a fully charged battery and aligns it, the control module 312 of the charging unit 3 controls the clamping mechanism 211 of the battery storage unit 21 to release, and the fully charged battery is loaded on the lifting platform 431; and

S600. The automatic battery replacement robot 4 fixes the fully charged battery to the electric vehicle 5 to be replaced. For example, after the automatic battery swapping robot 4 moves back to the bottom of the electric vehicle 5 and precisely locates it, the fully charged battery is fixed to the electric vehicle 5 through the lifting of the lifting platform 431 and the locking action of the unlocking mechanism 432 .

Wherein, when the battery storage unit 21 is arranged in the above-mentioned case i) (that is, the length direction of the power battery 6 is arranged perpendicular to the length direction of the area of the storage part 2), step S400 may further include:

S410. The automatic battery swapping robot 4 rotates in situ at the projected position of the power-deficient battery by a first set angle. Preferably, the first set angle can be 90°;

S420, the automatic battery swapping robot 4 moves to the projection position of the battery storage unit 21 in an idle state. For example, the automatic battery replacement robot 4 reaches the projected position of the battery storage unit 21 in an idle state by linear motion and in situ rotation; and

S430, the automatic battery replacement robot 4 fixes the power-depleted battery to the battery storage unit 21 in an idle state. For example, the dead battery is fixed to the battery storage unit 21 through the lifting of the lifting platform 431 and the locking action of the unlocking mechanism 432 .

It can be seen that it is precisely because of the free-moving setting of the automatic battery-swapping robot 4, that is, the setting of the automatic battery-swapping robot 4 that can move in a straight line and rotate in situ, so that the automatic battery-swapping robot 4 can remove the power-deficient battery. Finally, it can move out of the bottom of the electric vehicle 5 after rotating a certain angle. This action increases the range of motion of the automatic battery swapping robot 4 between the front and rear wheels, so that the automatic battery can be activated without lifting the vehicle to a very high height. The battery exchange robot 4 moves out from the bottom of the vehicle and completes the battery exchange, which reduces the impact of the wheels on the movement process of the automatic battery exchange robot 4 . In other words, this setting method reduces the difficulty of battery replacement and improves the efficiency of battery replacement.

Similarly, still when the battery storage unit 21 is arranged in the above-mentioned i) situation, step S600 may further include:

S610, the automatic battery replacement robot 4 carries the fully charged battery and moves to the projected position of the vehicle to be replaced;

S620. The automatic battery swapping robot 4 rotates at the projected position by a second set angle, and precisely aligns with the power-deficient battery. Preferably, the second set angle can also be 90°; and

S630. The automatic battery replacement robot 4 fixes the fully charged battery on the vehicle to be replaced.

The advantage of this arrangement is that, in addition to increasing the range of motion of the automatic battery-swapping robot 4 between the front and rear wheels when entering the bottom of the electric vehicle 5, the automatic battery-swapping robot 4 can also make the automatic battery-swapping robot 4 rotate according to 90° °Afterwards, the route from the electric vehicle 5 to the battery storage unit 21 in an idle state is returned on the original route, that is, the reverse operation is performed on the same road section, so that the design of the guide route can be omitted. Of course, the first set angle and the second set angle are not limited to the 90° described above, and those skilled in the art can also make adjustments so that the rotation angle of the automatic battery swapping robot 4 can meet specific application scenarios.

Referring to Fig. 6A to Fig. 6D, a complete battery swapping process of the charging and swapping station of the present invention may include: the electric vehicle 5 to be swapped enters the swapping platform 1 and performs rough positioning → the automatic swapping robot 4 moves to the electric The bottom of the car 5 is aligned with the dead battery (refer to FIG. 6A ) → the automatic battery replacement robot 4 lifts the lifting platform 431 and unlocks the unlocking mechanism 432, removes the dead battery, and rotates 90° clockwise ( Referring to Fig. 6B) → the automatic battery replacement robot 4 moves to the battery storage unit 21 in an idle state, and fixes the power-depleted battery to the clamping mechanism 211 of the battery storage unit 21 (refer to Fig. 6C) → the automatic battery replacement robot 4 moves to the loading There is a battery storage unit 21 with a fully charged battery, the control module 312 of the charging part 3 controls the clamping mechanism 211 to release, and the fully charged battery is carried on the lifting platform 431 of the automatic battery swapping robot 4 (refer to FIG. 6D ) → the automatic battery swapping robot 4 Carry the fully charged battery to reposition the projected position of the electric vehicle 5, and fix the fully charged battery with the electric vehicle 5→electric vehicle 5 out of the charging and swapping station through the locking of the unlocking mechanism 432. So far, the battery swapping process is over.

The charging part 3 is preferably arranged one-to-one with the battery storage unit 21 in a distributed arrangement. The automatic battery swapping robot 4 includes a main body 41, a walking part 42, a battery loading and unloading part, a positioning part, and a control part 44, and the automatic battery swapping robot 4 can complete picking up and sending batteries from the battery storage unit 21 and feeding the electric vehicle 5 without leaving the ground. The action of changing power. The automatic battery-swapping robot 4 can move in a straight line and rotate on the spot, and the setting method of completing the battery-swapping action without leaving the ground makes the automatic battery-swapping robot 4 have the advantage of high movement flexibility compared to the battery-swapping robot that depends on the track , thereby simplifying the structure of the charging and swapping station and improving the efficiency of the charging and swapping station. The modularized battery storage unit 21 and the most efficient arrangement and plane stacking arrangement between each battery storage unit 21 not only greatly increase the configuration flexibility and scope of application of the charging and swapping station, but also greatly increase the design of the charging and swapping station. The difficulty is significantly reduced, and the automatic battery swapping robot 4 does not need to be raised and lowered during the battery swapping process, thereby saving the setting of the lifting mechanism, reducing the cost, and further improving the power swapping efficiency. In addition, when the charging unit 3 adopts a distributed arrangement, each charging unit 31 can form a complete sub-module with the corresponding battery storage unit 21, which is more conducive to the modular management of the charging and swapping station, and also This makes the arrangement of the storage unit 2 of the charging and swapping station more flexible and more expansible.
