With the development of new energy technology, the devices using batteries are increased, and when the electric energy of electric equipment is exhausted, electric energy is usually supplemented by connecting a charging device, for example, an electric vehicle can be charged by connecting a charging pile. Compared with the mode of connecting charging devices such as a charging pile to supplement electric energy, charging can consume longer time, and user experience is affected.
The inventors have noted that replacement of the battery enables replenishing the electrical energy faster than charging. To this end, the inventors devised a power conversion device capable of supporting a battery and completing the replacement of the battery. Illustratively, the power conversion device includes a floating platform that is capable of supporting the battery during disassembly and assembly of the battery. The floating platform is usually provided with a positioning piece, and the positioning piece is matched with a positioning hole of the electric equipment to realize the positioning of the floating platform, other structures on the floating platform and the electric equipment.
The inventors have noted that the positioning members are typically fixed to the floating platform. The locating piece defines the highest position of the power conversion device in the height direction, so that the height dimension of the power conversion device is larger, and a larger space is occupied in the height direction. Because the locating part is fixed in the location platform, need the consumer to adapt to the height of locating part, general consumer's volume is great, and the high operation through consumer adaptation locating part is inconvenient, and battery replacement is inefficiency.
The inventors have attempted to provide the positioning member to be movable relative to the floating platform to adjust the height of the positioning member relative to the floating platform. In the case that the power conversion device is used for transporting the battery or the power conversion device is not operated, the positioning piece moves downwards relative to the floating platform so as to reduce the height of the positioning piece, thereby reducing the height dimension of the power conversion device. When the battery of the electric equipment needs to be replaced, the positioning piece is driven to move upwards relative to the floating platform so as to adjust the height of the positioning piece, and the positioning piece is matched with the electric equipment in a positioning way. The positioning matching with the electric equipment is realized through the movement of the positioning piece, the operation is simple, the efficiency is high, the positioning piece is adjusted to different height positions, and the positioning piece can adapt to the electric equipment with different heights.
After the power conversion device moves to the lower side of the electric equipment, the positioning piece moves upwards to be matched with the positioning hole of the electric equipment, and then the floating platform moves upwards to replace the battery. The inventor finds that in the process of lifting the floating platform, the positioning piece can continuously lift along with the floating platform, and the positioning hole of the electric equipment needs to have a larger size so as to meet the travel requirement of the positioning piece and avoid the electric equipment from interfering with the positioning piece. However, increasing the size of the positioning hole increases the limitation on the electric equipment, and affects the applicability of the electric switching device. In addition, the process that the locating piece stretches into the guiding hole is carried out separately from the process that the floating platform upwards moves, and time consuming is long, and battery replacement efficiency is low.
In view of this, an embodiment of the present application provides a method for replacing a battery of an electric device, including: moving the power conversion device to the lower side of the electric equipment; the floating platform of the power conversion device moves upwards to be close to the electric equipment, and the positioning piece arranged on the floating platform moves upwards relative to the floating platform; when the positioning piece is inserted into the positioning hole of the electric equipment and reaches a first preset position, the floating platform continues to move upwards, the positioning piece moves downwards relative to the floating platform, and at least part of the positioning piece is kept in the positioning hole; the floating platform is configured to support or mount the battery to the powered device when the floating platform is moved to the second predetermined position.
In this embodiment, in the process that the positioning member moves upward to extend into the positioning hole, the upward movement of the floating platform and the upward movement of the positioning member relative to the floating platform are performed synchronously, so that the speed of extending the positioning member into the positioning hole can be increased, and time is saved. When the locating piece inserts the locating hole of consumer and reaches first preset position, the locating piece moves down for floating platform, can reduce the removal range of locating piece under floating platform's drive like this, reduces the locating piece and passes in the locating hole, reduces the requirement to the locating hole size, improves the suitability of trading the electric installation.
The embodiment of the application discloses a battery replacement method of electric equipment, a battery replacement device and a battery replacement system for realizing the battery replacement method, which can be used for vehicles. The vehicle can be a fuel oil vehicle, a fuel gas vehicle or a new energy vehicle, and the new energy vehicle can be a pure electric vehicle, a hybrid electric vehicle or a range-extended vehicle and the like.
Fig. 1 is a flowchart illustrating a method for replacing a battery of an electric device according to some embodiments of the present application; fig. 2 to fig. 6 are schematic diagrams of a battery replacing device according to some embodiments of the present application in a battery replacing process.
As shown in fig. 1 to 6, a battery replacement method of an electric device according to an embodiment of the present application includes:
s100, moving the power conversion device 1 to the lower side of the electric equipment 2;
s200, the floating platform 11 of the power conversion device 1 moves upwards to be close to the electric equipment 2, and the positioning piece 12 arranged on the floating platform 11 moves upwards relative to the floating platform 11;
s300, when the positioning piece 12 is inserted into the positioning hole 21 of the electric equipment 2 and reaches a first preset position, the floating platform 11 continues to move upwards, the positioning piece 12 moves downwards relative to the floating platform 11, and at least part of the positioning piece 12 is kept in the positioning hole 21;
s400, floating platform 11 is used to support battery 22 detached from powered device 2 or to mount battery 22 to powered device 2 when floating platform 11 is moved to the second predetermined position.
The battery replacement method of the present embodiment may be used to remove the battery 22 to be charged, which is dead of electric energy on the electric consumer 2, and may also be used to mount the full-charged battery 22 on the electric consumer 2. In some examples, in step S100, floating platform 11 of power conversion device 1 is not provided with battery 22, and correspondingly, in step S400, floating platform 11 is used to support battery 22 detached from powered device 2. In other examples, in step S100, battery 22 is supported on floating platform 11, and floating platform 11 is used to lift and mount battery 22 to powered device 2.
In step S200, the end of the positioning member 12 facing the positioning hole 21 is moved upward with respect to the floating platform 11.
Illustratively, in step S200, floating platform 11 moves upward at a rate V1, positioning member 12 moves upward relative to floating platform 11 at a rate V2, and at this time, floating platform 11 moves upward at a rate v1+v2. The upward movement of the floating platform 11 and the upward movement of the positioning member 12 relative to the floating platform 11 are synchronously performed, so that the speed of the positioning member 12 extending into the positioning hole 21 can be increased, the time for inserting the positioning member 12 into the positioning hole 21 can be saved, and the floating platform 11 can be lifted by utilizing the time, so that the efficiency is improved.
In step S300, when the positioning member 12 is inserted into the positioning hole 21 of the electric device 2 and reaches the first predetermined position, the positioning member 12 is in plug-in fit with the positioning hole 21; in the process that the floating platform 11 continues to move upwards, the cooperation of the positioning piece 12 and the positioning hole 21 can guide the floating platform 11 to move, so that the alignment precision between the floating platform 11 and the electric equipment 2 is ensured, and the efficiency of disassembling and assembling the battery 22 is improved.
Illustratively, in step S300, floating platform 11 moves upward at a rate V1 and positioning member 12 moves downward relative to floating platform 11 at a rate V3, such that the rate v4=v1-V3 of movement of positioning member 12 in positioning hole 21. V4 may be greater than 0, equal to 0, or less than 0. When V4 is greater than 0, the positioning member 12 moves upward in the positioning hole 21; when V4 is less than 0, the positioning member 12 moves downward in the positioning hole 21; when V4 is equal to 0, the positioning member 12 remains stationary in the positioning hole 21. In other words, in step S300, after the positioning member 12 reaches the first predetermined position, the positioning member 12 may be raised, lowered, or stationary in the positioning hole 21, so long as the engagement of the positioning member 12 with the positioning hole 21 is maintained before the floating platform 11 moves to the second predetermined position. The present embodiment can reduce the moving rate of the positioning member 12 in the positioning hole 21, and reduce the stroke of the positioning member 12 in the positioning hole 21.
When the floating platform 11 moves to the second predetermined position, the floating platform 11 stops moving, and the battery 22 is removed and installed by the power exchanging apparatus 1. Illustratively, when the battery 22 to be charged of the powered device 2 is removed by the power conversion device 1, the floating platform 11 may support the battery 22, thereby reducing the risk of dropping the battery 22.
In step S400, after floating platform 11 has moved to the second predetermined position, positioning member 12 may continue to move downward with respect to floating platform 11 or may stop moving with respect to floating platform 11.
In the present embodiment, in the process that the positioning member 12 moves upward to extend into the positioning hole 21, the upward movement of the floating platform 11 and the upward movement of the positioning member 12 relative to the floating platform 11 are performed synchronously, so that the speed of extending the positioning member 12 into the positioning hole 21 can be increased, the time for inserting the positioning member 12 into the positioning hole 21 can be saved, and the floating platform 11 can be lifted by utilizing the time, thereby improving the efficiency. When the positioning piece 12 is inserted into the positioning hole 21 of the electric equipment 2 and reaches the first preset position, the positioning piece 12 moves downwards relative to the floating platform 11, so that the moving amplitude of the positioning piece 12 under the drive of the floating platform 11 can be reduced, the travel of the positioning piece 12 in the positioning hole 21 is reduced, the requirement on the size of the positioning hole 21 is reduced, and the applicability of the electric exchange device 1 is improved.
In some embodiments, the battery replacement method further comprises: s500, after the floating platform 11 moves to the second predetermined position, the positioning member 12 continues to move downward with respect to the floating platform 11 and is disengaged from the positioning hole 21.
In this embodiment, the positioning member 12 can move downward by using the time of the floating platform 11 to disassemble the battery 22, so as to reduce the height of the positioning member 12 protruding from the floating platform 11, reduce the height dimension of the power exchanging device 1, and improve the efficiency of the power exchanging device 1.
In some embodiments, in step S300, the ratio k of the size of the portion of the positioning member 12 held within the positioning hole 21 to the size of the positioning hole 21 in the axial direction of the positioning hole 21 is 0.2 to 0.95.
The smaller the value of k, the smaller the fit between the positioning member 12 and the positioning hole 21, the greater the pressure between the positioning member 12 and the wall of the positioning hole 21, and the higher the risk of damaging the positioning member 12. The larger the value of k, the smaller the movement space reserved by the positioning hole 21 for the positioning member 12, and the higher the risk that the positioning member 12 collides with the bottom wall of the positioning hole 21 due to the velocity error. The inventor calculates and tests to limit the value of k to 0.2-0.95, so that the matching size between the positioning piece 12 and the positioning hole 21 can be ensured, and the positioning hole 21 reserves a certain moving space for the positioning piece 12, thereby ensuring the positioning precision and reducing the risk of damaging the positioning piece 12.
In some embodiments, in step S300, the positioning member 12 is maintained in a first predetermined position.
Illustratively, in step S300, the value of V4 is equal to 0 and the positioning member 12 remains stationary within the positioning bore 21. After floating platform 11 reaches the second predetermined position, positioning member 12 may be disengaged from the first predetermined position.
In this embodiment, the positioning member 12 and the positioning hole 21 are relatively stationary, so as to improve the stability of the cooperation between the positioning member 12 and the positioning hole 21 and improve the alignment accuracy of the floating platform 11 and the electric device 2 in the process of guiding the floating platform 11 to move towards the second predetermined position.
In some embodiments, step S400 includes: s410, when floating platform 11 moves to the second preset position, floating platform 11 stops moving and supports battery 22 of electric equipment 2; s420, unlocking mechanism 13 installed on floating platform 11 releases the lock between battery 22 and power utilization main body 23 of electric equipment 2.
In this embodiment, the floating platform 11 may drive the unlocking mechanism 13 to approach the electric device 2, so that the unlocking mechanism 13 releases the lock between the battery 22 and the electric main body 23 of the electric device 2; the floating platform 11 can support the battery 22 after unlocking the battery 22, thereby preventing the battery 22 from falling down and improving safety.
In some embodiments, the battery replacement method further comprises: s600, after releasing the lock between the battery 22 and the electricity consumption body 23, the floating platform 11 moves downward to separate the battery 22 from the electricity consumption body 23.
In this embodiment, the floating platform 11 can be lowered after the battery 22 is removed to lower the height of the power conversion device 1 and the battery 22, so as to facilitate the battery 22 to be transported by the power conversion device 1.
The flow of the battery replacement method according to an embodiment of the present application is briefly described below with reference to fig. 2 to 6.
As shown in fig. 2, when the battery 22 of the powered device 2 needs to be charged, the power conversion device 1 moves to the lower side of the powered device 2.
As shown in fig. 3, floating platform 11 of power conversion device 1 moves upward to approach powered device 2, and at the same time, positioning member 12 moves upward from the initial position with respect to floating platform 11 until positioning member 12 reaches the first predetermined position. The initial position refers to the initial position of the positioning member 12 on the floating platform 11.
As shown in fig. 4, when positioning member 12 is inserted into positioning hole 21 of powered device 2 and reaches the first predetermined position, floating platform 11 continues to move upward, positioning member 12 moves downward with respect to floating platform 11, and positioning member 12 is maintained at the first predetermined position.
