Those of skill in the art will explicitly and implicitly appreciate that the described embodiments of the application may be combined with other embodiments.

With the development of new energy technology, the application field of batteries is becoming wider and wider, for example, the batteries can be used as a power source to provide power for vehicles, and the use of non-renewable resources is reduced. Under the condition that the electric quantity of the battery in the vehicle is insufficient to support the vehicle to continue running, the vehicle can be charged by charging equipment such as a charging pile, namely, the battery in the vehicle is charged, so that the battery can be circularly used for charging and discharging. However, the battery charging takes a long time, which limits the cruising use of the vehicle.

In order to improve the endurance utilization rate of the vehicle, a power conversion technology is generated. The battery replacement technology adopts a mode of 'vehicle-electricity separation', and can provide battery replacement service for the vehicle through a battery replacement station, namely, the battery can be quickly taken down or installed from the vehicle. The battery removed from the vehicle may be placed in a battery storage mechanism of the power exchange station for charging in preparation for a subsequent power exchange for the vehicle entering the power exchange station.

In the conventional technology at present, the actions of detaching a battery to be detached on electric equipment, installing the battery to be installed on electric equipment, transporting the battery to be detached and the battery to be installed are all performed by a rail guided vehicle (rail guided vehicle, RGV). Specifically, after the powered device is parked on the power conversion platform, the RGV first removes the battery to be removed from the powered device. Then, the battery is moved to the vicinity of the battery storage mechanism, and the battery to be disassembled is placed in the battery storage mechanism. Next, a battery to be mounted is acquired, and the battery to be mounted is conveyed to the lower portion of the electric equipment. Thereafter, the RGV mounts the battery to be mounted to the powered device.

Obviously, the RGV works in series in the whole working process, and the working mode needs longer time, so that the vehicle has longer power change time and the user experience is influenced.

Based on the above, the embodiment of the application provides a battery power changing method, by arranging a dismounting device for mounting and dismounting a battery and a moving device for conveying the battery, the dismounting device is controlled to convey the battery to be mounted while dismounting the battery to be dismounted, and the dismounting device is controlled to convey the dismounted battery to a battery storage mechanism while mounting the battery to be mounted on electric equipment. That is, the whole power conversion process is performed in parallel, so that the power conversion time can be effectively reduced, and the user experience is further improved.

Fig. 1 shows a schematic diagram of a power conversion system according to an embodiment of the application. The battery power exchanging method of the embodiment of the application can be applied to the power exchanging system. As can be seen from fig. 1, the consumer is a battery-powered vehicle.

As shown in fig. 1, the battery change system 100 may include a battery storage mechanism 101. The battery storage mechanism 101 may be configured with a plurality of batteries. The battery storage mechanism 101 may include a battery charging compartment and a battery buffer. The battery may be stored within a battery charging bin so that the battery may be charged. The battery buffer device may be used to temporarily store the battery to be removed, which is replaced by the vehicle.

In addition to the battery rack battery storage mechanism, the power conversion system 100 may also include a stacker 102, a mobile device 110, and a dismounting device (not shown in fig. 1). The dismounting device can dismount the battery to be dismounted of the electric vehicle 1, and the stacker 102 can also transport the battery to be mounted on the battery storage mechanism 101 to the moving device 110 while the dismounting device dismantles the battery to be dismounted, and the moving device 110 carries the battery to be mounted to the electric vehicle 1. In addition, the dismounting device can also mount the battery to be mounted on the battery-changing vehicle 1, meanwhile, the mobile device 110 can transport the battery to be dismounted, which is replaced from the battery-changing vehicle 1, to the battery buffer device, and the stacker 102 transports the battery to be dismounted in the battery buffer device to the battery storage mechanism 101, so that the battery storage mechanism 101 charges the battery to be dismounted.

The power plant 100 may also include a power conversion platform 200. Fig. 2 shows a schematic representation of a battery-powered vehicle 1 traveling on a battery-powered platform 200. In the battery exchange platform 200, the dismounting device can exchange the battery on the battery exchange vehicle 1. The X direction in fig. 1 and 2 may be a traveling direction of the battery exchange vehicle 1 on the battery exchange platform 200, and the Y direction may be a traveling direction of the mobile device 110 on the battery exchange platform 200. Illustratively, the mobile device 110 may be moved in the Y-direction to the vicinity of the battery exchange vehicle 1 via a guide rail on the battery exchange platform 200.

As an example, in the embodiment shown in fig. 1 and 2, the level shifter 200 may include a front ramp 104, a front wheel alignment roller 106, a rear ramp 103, a rear wheel alignment roller 105. The battery-powered vehicle 1 may travel from the rear ramp 103 toward the front ramp 104, as shown in fig. 2. In the traveling direction of the battery change vehicle 1, the front wheel positioning roller 106 and the rear wheel positioning roller 105 may be located between the front ramp 104 and the rear ramp 103. Front wheel alignment roller 106 may be disposed adjacent to front ramp 104 and rear wheel alignment roller 105 may be disposed adjacent to rear ramp 103. The front wheel positioning roller 106 may be used to position the front wheels of the vehicle 1. The rear wheel positioning roller 105 may be used to position the rear wheels of the vehicle 1. The battery exchanging platform 200 can position the battery exchanging vehicle 1 in the X-direction and the Y-direction by the front wheel positioning roller 106 and the rear wheel positioning roller 105 so that the battery exchanging vehicle 1 can be fixed with respect to the battery exchanging platform 200. When the battery changing platform 200 finishes positioning the battery changing vehicle 1, the dismounting device can dismount the battery to be dismounted in the vehicle.

Optionally, a locking mechanism may be further disposed in the chassis of the battery-changing vehicle 1, and a locking portion corresponding to the locking mechanism is disposed in the battery, where the locking mechanism may be used to lock the locking portion, so that the battery may be lockably mounted on the chassis of the battery-changing vehicle 1. Correspondingly, the locking structure may also be configured to release the locking of the locking portion, so that the battery may be unlocked and detached from the chassis of the battery-powered vehicle 1. In the process of disassembling the battery and installing the battery by the disassembling device, the disassembling device can push the battery upwards to unlock and lock the locking part in the battery and the locking mechanism in the battery replacing vehicle 1, so that the disassembly and the installation of the battery are completed. It should be understood that the dismounting device may also unlock and lock the locking portion and the locking mechanism by other means than pressing, such as bolts.

The battery in the above description may be a sodium ion battery or the like, and is not particularly limited in the embodiment of the present application. In terms of battery scale, the power battery in the embodiment of the present application may be an electric core/battery unit, or may be a battery module or a battery pack, which is not particularly limited in the embodiment of the present application. The battery can supply power to the motor of the electric vehicle 1 as a power source, and also to the gas electric device in the electric vehicle 1. For example, the battery may power an in-vehicle air conditioner, an in-vehicle player, or the like. In colloquial terms, the battery in the foregoing may be a "true" battery.

Alternatively, the battery may be a battery pack similar to a battery, which may have the same housing as the battery, i.e., the battery pack may be mounted to a vehicle, but the battery pack does not include a battery cell and cannot provide power to the vehicle. In colloquial terms, the battery filler blocks may be referred to as "dummy" batteries. The battery filler block may also be placed in the battery storage mechanism. For example, the battery charging bin may be divided into two parts, one part being a charging bin for placing a "true" battery, which may be charged. The other part is a charging bin for placing the battery filling block, and is not used for charging the battery filling block. Alternatively, the charging bin for placing the battery filler blocks may not have a charging function, but only have a containing function.

Fig. 3 shows a schematic flow chart of a method 300 of battery replacement according to an embodiment of the application. The method 300 may be applied to a power conversion system. The power conversion system may be, for example, the power conversion system 100 shown in fig. 1. The power conversion system comprises a dismounting device and a moving device, wherein the dismounting device is arranged at a position corresponding to the chassis of the electric equipment.

The method 300 may also be performed by a control unit in a power conversion system, such as by a station control system. The method 300 may include at least some of the following.

S310: after the electric equipment is stopped at the preset position, the disassembly and assembly device is controlled to disassemble the battery to be disassembled of the electric equipment, and the mobile device is controlled to convey the battery to be assembled to the disassembly and assembly device.

S320: after the dismounting device dismantles the battery to be dismounted, the dismounting device is controlled to mount the battery to be mounted on the electric equipment, and the mobile device is controlled to convey the battery to be dismounted by the dismounting device to the battery storage mechanism.

The battery to be disassembled and/or the battery to be installed comprise shielding devices, and the shielding devices are used for shielding interfaces between the battery to be disassembled and the electric equipment and/or used for shielding interfaces between the battery to be installed and the electric equipment.

Alternatively, the mobile device may be an RGV, or may be an automated guided vehicle (automated guided vehicle, AGV), although other devices capable of movement are possible.

The dismounting device may be, but is not limited to, a device with a robotic arm. The electrical device may be, but is not limited to, a vehicle, a ship, a spacecraft, etc., and the predetermined location may be, for example, a power conversion platform as shown in fig. 2. The battery storage mechanism can be a charging bin or a battery buffer device and the like.

Alternatively, the shielding means may not comprise a battery cell. For example, the shielding device may be the battery pack mentioned above, or may be other devices capable of shielding the interface.

Alternatively, the profile of the shielding device may be exactly the same as the profile of the battery to be mounted (or the battery to be dismounted). Alternatively, the shielding device may be the same size as the battery to be detached (or the battery to be mounted), while being different from the battery to be detached (or the battery to be mounted) in other aspects, such as color, etc. In this way, the shielding device can be better distinguished from the battery to be mounted (or the battery to be dismounted), and the problem that the shielding device cannot be mounted due to oversized shielding device or is moved in the electric equipment due to undersize of the shielding device can be avoided.

Alternatively, the powered device may include a number of batteries equal to the number of batteries to be removed. For example, the electric equipment comprises K batteries, and the number of the batteries to be detached and the number of the batteries to be installed are also K. Alternatively, the powered device may include a greater number of batteries than the number of batteries to be removed. For example, the electric equipment comprises K batteries, the number of the batteries to be detached and the number of the batteries to be installed are L, and L is smaller than K. I.e. only a part of the batteries in the consumer are replaced.

The battery to be mounted may comprise a full battery and a shielding device, the sum of the number of full batteries and shielding devices being equal to the number of batteries to be dismounted. For example, the battery to be disassembled comprises 4 battery cells with power shortage, and the battery to be installed comprises 3 battery cells with power full and 1 shielding device. Through with full electric battery and shelter from the device and install the position of waiting to dismantle the battery jointly, can avoid waiting to dismantle the battery and dismantle the back, partial position vacant leads to the interface to expose outside problem to can improve the security performance of consumer.

Alternatively, the battery to be disassembled may include a battery under-run and a shutter device, the sum of the number of battery under-run and shutter devices being equal to the number of batteries to be installed. For example, the battery to be disassembled includes 2 full cells and 2 blinders, and the battery to be installed includes 4 full cells. In other words, before the power is replaced, 2 batteries supply power to the electric equipment, and after the power is replaced, 4 batteries supply power to the electric equipment. According to the technical scheme, the sum of the number of the battery with the power consumption and the shielding device is equal to the number of the batteries to be installed, namely, the number of the true batteries on the electric equipment after power conversion is larger than the number of the true batteries before power conversion, and further the endurance mileage of the electric equipment can be effectively improved.

Of course, both the battery to be disassembled and the battery to be installed may include shielding means. If the battery to be disassembled comprises 2 battery cells and 2 shielding devices, the battery to be installed comprises 2 battery cells full of electricity and 2 shielding devices.

The battery to be detached may include, in addition to the battery for power shortage and the shielding means, an abnormal battery such as a battery in which thermal runaway occurs, a battery in which deformation occurs in shape, or the like.

It should be noted that the number of shielding devices included in the battery to be detached and the number of shielding devices included in the battery to be installed may be equal or unequal, which is not particularly limited in the embodiment of the present application.

In one implementation, the number of mobile devices may be one. I.e. the mobile device carries both the battery to be disassembled and the battery to be mounted. For example, only one bin may be provided on the mobile device. In this case, the mobile device carries only one battery at a time.

As another example, a plurality of bins may be provided on the mobile device. Thus, the mobile device can transport a plurality of batteries at a time, for example, the mobile device can be controlled to simultaneously transport a plurality of batteries to be installed to the dismounting device while controlling the dismounting device to dismount the batteries to be dismounted of the electric equipment. And when the disassembly and assembly device is controlled to install the battery to be installed on the electric equipment, the mobile device can be controlled to simultaneously convey a plurality of batteries to be disassembled to the battery storage mechanism. Therefore, the power conversion time of the electric equipment can be effectively reduced. As an example, a portion of the plurality of bins is used to place a battery to be installed and another portion of the plurality of bins may be used to place a battery to be disassembled.

In another implementation, the number of mobile devices may be multiple. As an example, each of the plurality of mobile devices may carry either a battery to be disassembled or a battery to be installed.

As another example, the mobile device may include a first mobile device and a second mobile device. In this case, S310 may specifically include: after the electric equipment is stopped at a preset position, the dismounting device is controlled to dismount the battery to be dismounted of the electric equipment, and meanwhile, the first mobile device is controlled to convey the battery to be mounted to the dismounting device. S320 may specifically include: after the dismounting device dismantles the battery to be dismounted, the dismounting device is controlled to mount the battery to be mounted on the electric equipment, and meanwhile, the second moving device is controlled to convey the battery to be dismounted by the dismounting device to the battery storage mechanism.

Alternatively, the size and dimension of the first mobile device may be the same as or different from the size and dimension of the second mobile device, which is not particularly limited in the embodiments of the present application.

Alternatively, the first mobile device may carry one battery at a time to be mounted. Alternatively, a plurality of batteries to be mounted may be carried at a time, in which case the first moving means may be provided with a plurality of compartments, each for placing one battery to be mounted, for example. Similarly, the second mobile device may carry one battery to be removed or multiple batteries to be removed at a time.

As an example, the number of first mobile devices may be one. When the number of the batteries to be installed that the powered device needs to replace is plural and the first mobile device carries one battery to be installed at a time, S310 may specifically include: the disassembly and assembly device is controlled to disassemble the battery to be disassembled, and the first moving device is controlled to convey a first battery to be assembled in the plurality of batteries to be assembled to the disassembly and assembly device, and when the disassembly and assembly device is used for assembling the first battery to be assembled, the first moving device returns to the battery storage mechanism and conveys a second battery to be assembled in the plurality of batteries to be assembled to the disassembly and assembly device. And the operation is repeated in a circulating way until the dismounting device is used for mounting a plurality of batteries to be mounted on the electric equipment.

The number of second mobile devices may also be one. When the number of the to-be-disassembled batteries that the disassembling device needs to disassemble is plural and the second mobile device conveys one to-be-disassembled battery at a time, S320 may specifically include: the disassembly and assembly device is controlled to install the battery to be installed on the electric equipment, the second moving device is controlled to convey a first battery to be disassembled of the plurality of batteries to the battery storage mechanism, then the second moving device is controlled to return to a preset position, and the second moving device is controlled to convey a second battery to be disassembled of the plurality of batteries to the battery storage mechanism. And the second moving device conveys all the batteries to be disassembled to the battery storage mechanism.

As another example, the number of first mobile devices may be a plurality. When the quantity of the battery to be installed that the consumer was changed is a plurality of, control first mobile device transport the battery to be installed to dismouting device, specifically can include: and controlling each first mobile device in at least part of the first mobile devices to convey the battery to be installed to the dismounting device at a time, wherein the time for conveying the battery to be installed by at least two first mobile devices in at least part of the first mobile devices is overlapped.

According to the technical scheme, a plurality of first mobile devices are arranged, and the time for conveying the battery to be installed by at least two first mobile devices in the plurality of first mobile devices is overlapped. I.e. the first mobile device is also carrying the battery to be installed in parallel, which can further reduce the battery change time.

If the number of the batteries to be mounted is equal to the number of the first mobile devices, each of the first mobile devices can be controlled to convey one battery to be mounted to the dismounting device. If the number of the batteries to be mounted is smaller than the number of the first mobile devices, the first mobile devices can be controlled to convey one battery to be mounted to the dismounting device at a time.

When at least part of the first moving device is controlled to convey the battery to be installed, at least part of the first moving device can be controlled to convey the battery to be installed to the dismounting device at the same time. Alternatively, at least one of the first moving devices may be controlled to convey the battery to be mounted to the dismounting device every a preset period of time. The embodiment of the application does not specifically limit the preset time period, and for example, the preset time period may be 5s. For another example, the preset time period may be determined according to a distance between the first moving device and the detachable device.

The number of the second moving devices may be plural, and when the number of the battery to be disassembled detached by the disassembling device is plural, the second moving device is controlled to convey the battery to be disassembled detached by the disassembling device to the battery storing mechanism, which may include: and controlling each of at least part of the second mobile devices to convey the battery to be disassembled to the battery storage mechanism at a time, wherein the time for conveying the battery to be disassembled to the battery storage mechanism by at least two of the at least part of the second mobile devices is overlapped.

According to the technical scheme, a plurality of second mobile devices are arranged, and the time for conveying the battery to be detached by at least two second mobile devices in the plurality of second mobile devices is overlapped. I.e. the second mobile device is also carrying the battery to be removed in parallel, which can further reduce the battery change time.

If the number of the batteries to be disassembled is equal to the number of the second mobile devices, each of the second mobile devices can be controlled to convey one battery to be disassembled to the battery storage mechanism. If the number of the batteries to be disassembled is smaller than the number of the second moving devices, the second moving devices can be controlled to convey one battery to be disassembled to the battery storage mechanism at a time.

At least part of the second moving means may be controlled to simultaneously convey the battery to be disassembled to the battery storage mechanism while controlling at least part of the second moving means to convey the battery to be disassembled. Alternatively, at least one of the second moving devices may be controlled to convey the battery to be detached to the battery storage mechanism every a preset period of time. The embodiment of the application does not specifically limit the preset time period, and for example, the preset time period may be 5s. For another example, the preset time period may be determined based on a distance between the second mobile device and the battery storage mechanism. For another example, the predetermined period of time may be determined according to the time for which the dismounting device dismantles the battery to be dismounted, that is, one battery to be dismounted for each dismounting device dismantles, and one second moving device conveys one battery to be dismounted.

In one embodiment, controlling the first mobile device to transport the battery to be mounted to the dismounting device may include: and controlling the first moving device to convey the battery to be installed to the dismounting device through the first path. Controlling the second moving device to convey the battery to be disassembled detached from the detaching device to the battery storing mechanism may include: the second moving device is controlled to convey the to-be-disassembled battery storage mechanism through a second path. Wherein the first path and the second path are different.

The first path and the second path are not particularly limited in the embodiment of the present application. For example, the first path may be a path from the left of the powered device to the battery storage mechanism and the second path may be a path from the right of the powered device to the battery storage mechanism. Further exemplary, the first path may be a path from a head of the powered device to the battery storage mechanism, and the second path may be a path from a tail of the powered device to the battery storage mechanism.

In another embodiment, the path of the first mobile device carrying the battery to be installed and the path of the second mobile device carrying the battery to be removed are both third paths, and the method 300 may further include: the first mobile device and the second mobile device are controlled to time-division multiplex the third path.

Alternatively, the first moving means and the second moving means may be controlled to alternately convey the battery to be mounted and the battery to be dismounted through the third path. For example, the first mobile device and the second mobile device are controlled to convey the battery to be mounted and the battery to be dismounted in the order of the first mobile device, the first second mobile device, the second first mobile device, the second mobile device … …, the last first mobile device, and the last second mobile device. For another example, the first moving device and the second moving device are controlled to convey the battery to be mounted and the battery to be dismounted in the order of the first moving device, the second first moving device, the first second moving device, the second moving device … …, the last second moving device, and the last second moving device.

Optionally, the first mobile device may be controlled to transport the battery to be detached after transporting the battery to be installed; alternatively, the second mobile device may be controlled to transport the battery to be mounted after transporting the battery to be dismounted.

It should be understood that in the embodiments of the present application, "first", "second" and "third" are merely for distinguishing different objects, and do not limit the scope of the embodiments of the present application.

In some embodiments, the path of the first mobile device to convey the battery to be mounted to the dismounting device may be the same as or different from the path of returning from the dismounting device to the original position. Similarly, the path of the second moving means for carrying the battery to be detached to the battery storage mechanism and the path from the home position to the attaching and detaching means may be the same or different.

It should be noted that, the original position in the foregoing may refer to a position where the first mobile device and the second mobile device are located when no powered device is powered.

For example, as shown in fig. 4 to 9, the number of the batteries to be detached and the number of the batteries to be installed are 2, 2a and 2b are second moving devices, 1a and 1b are first moving devices, 4 ellipses are tires of electric equipment, and R is a detaching device. As can be seen from fig. 4, the first moving means 1a and 1b carry the battery to be mounted to the dismounting device along the path M, and the second moving means 2a and 2b are also moved from the original position to the dismounting device along the path M. As can be seen from fig. 5 to 9, after the dismounting device dismounts the batteries to be dismounted 2, the second moving devices 2a and 2b each convey one battery to be dismounted, and convey the battery to be dismounted to the battery storage mechanism through the path N. As can be seen from fig. 7 to 9, after the dismounting device dismounts the battery to be dismounted on the electric device and installs the battery to be installed carried by the first moving device 1a on the electric device, both the first moving devices 1a and 1b move forward by one step so that the dismounting device installs the battery to be installed carried by the first moving device 1b on the electric device. After that, the first moving devices 1a and 1b return to the original positions along the path M.

It can be seen that the path of the first moving means for transporting the battery to be mounted to the dismounting device is the same as the path from the dismounting device to the home position, and the path of the second moving means for transporting the battery to be dismounted to the battery storage mechanism is different from the path from the home position to the dismounting device.

In some embodiments, after the first mobile device conveys the battery to be installed to the dismounting device, the method 300 may further include: the first moving device and the second moving device are respectively arranged at two sides of the dismounting device.

According to the technical scheme, the first mobile device and the second mobile device are respectively arranged on two sides of the dismounting device, so that the situation that the battery to be dismounted is mixed with the battery to be mounted is difficult to occur in the working process of the dismounting device, the power conversion efficiency is improved, and the normal operation of the power conversion process is ensured.

Alternatively, the mobile devices are arranged sequentially, and the first mobile device is arranged after the second mobile device. For example, referring again to fig. 4, after the first moving device and the second moving device reach the dismounting device, the first moving device and the second moving device are arranged in sequence and the first moving device is arranged behind the second moving device.

In the embodiment of the application, the dismounting device is only used for dismounting the battery to be dismounted and mounting the battery to be mounted, and the battery to be dismounted and the battery to be mounted do not need to be transported as in the conventional technical means. Thus, the method 300 may further comprise: before the electric equipment is parked at the preset position, the dismounting device is arranged below the preset position.

It should be understood that "lower" in the embodiments of the present application means the same direction as the direction of gravity.

Alternatively, referring again to fig. 2, if the predetermined location is a power conversion platform and the power conversion platform includes a ramp as shown in fig. 2, i.e., a gap is provided between the power conversion platform and the ground, the dismounting device may be disposed on the ground.

Alternatively, the dismounting device may be arranged below the ground. For example, a space capable of accommodating the dismounting device is provided below the ground in advance at a position corresponding to the chassis of the electric device, and the space is used for accommodating the dismounting device. The dismounting device is arranged below the ground, and electric equipment does not need to be lifted to an excessive height, so that the safety of the electric equipment can be effectively ensured, and the user experience can be improved.

Because the reason of taking shock into account is provided with the spring on the tire of consumer generally, if the tire contacts with the preset position, the existence of spring can influence the location of battery for the dismouting device dismantles the action of waiting to dismantle the battery and installing waiting to install the battery more difficult, seriously influences the conversion efficiency.

Based on this, the power conversion system may further comprise a lifting device, such as the lifting device 300 in fig. 1 and 2. In this case, the method 300 may further include: the lifting device is controlled to lift the electric equipment to a preset height, so that the disassembly and assembly device disassembles the battery to be disassembled and installs the battery to be installed on the electric equipment; after the battery to be installed is installed on the electric equipment by the dismounting device, the electric equipment is controlled to be lowered to the preset position by the lifting device.

According to the technical scheme, when the dismounting device dismantles the battery to be dismounted and the battery to be mounted is mounted, the electric equipment is lifted, so that the influence of the spring on the tire on the battery positioning can be avoided, the dismounting device can accurately position the battery to be dismounted and can accurately mount the battery to be mounted on the electric equipment after the battery to be dismounted is dismounted, and the electricity exchanging efficiency is effectively improved.

Alternatively, the predetermined height may be less than 50 cm. For example, the lifting device can be controlled to lift the electric equipment until the tire of the electric equipment is just lifted off the ground.

The preset height is smaller than 50 cm, namely the lifting device lifts the electric equipment lower, so that on one hand, the time for lifting the electric equipment can be saved, and the power change time is further shortened; on the other hand, if the electric equipment is lifted too high, the situation that the electric equipment falls down and the like possibly occurs, the preset height is smaller than 50 cm, the occurrence of the situations can be avoided, and the safety of the electric equipment is ensured.

Of course, the embodiment of the application can also not lift the electric equipment, namely, the preset height is 0.

In the embodiment of the present application, the sequence number of each process does not mean the sequence of execution sequence, and the execution sequence of each process should be determined by its function and internal logic, and should not constitute any limitation on the implementation process of the embodiment of the present application.
