[0002] In recent years, with the increasing popularity of electric vehicles and distributed energy storage systems, battery swap cabinets, as facilities that provide rapid battery replacement services, have seen an increasing number of applications. Existing battery swap cabinets typically feature multiple battery compartments, requiring users to remove depleted batteries and replace them with fully charged ones, or wait for the batteries to complete charging within the compartments. However, both electric vehicle batteries and batteries specifically designed for energy storage systems are often quite heavy, making the process of handling them extremely laborious. Even more inconvenient, when replacing a battery, users must precisely lift the heavy battery to the same height as the battery compartment opening, overcome docking resistance, and push it horizontally into the compartment until the charging port is fully connected. This series of operations requires a high level of physical strength from the user, making it an extremely unfriendly experience for those with limited physical strength, female users, or the elderly. Not only does this introduce the risk of operational failure, but the battery may slip out of their hands, leading to personal injury or equipment damage. Summary of the Invention

[0029] In one embodiment of the present invention, the lifting assembly 5 is symmetrically arranged on both sides of the surface of the battery exchange cabinet 1, and the lifting assemblies 5 on both sides are respectively connected to the two sides of the lifting plate 9. The lifting assembly 5 includes a lifting motor 6 and a lifting screw 8. The lifting screw 8 can be rotatably arranged in the lifting slot 7. The lifting slot 7 is opened on one side surface of the battery exchange cabinet 1. The lifting motor 6 is installed above one side of the battery exchange cabinet 1, and the output end of the lifting motor 6 is connected to one end of the lifting screw 8.

[0030] In one embodiment of the present invention, lifting parts 40 are fixedly provided on both sides of the lifting plate 9, the lifting parts 40 are slidingly connected to the lifting slot 7 and are threadedly connected to the lifting screw 8, the lifting plate 9 is located above the platform 11, and the platform 11 is fixedly provided at the bottom of the battery exchange cabinet 1, and a plurality of support plates 41 are fixedly provided on the surface of the lifting plate 9, and a first conveying roller 43 is provided on the surface of the support plate 41, and a second conveying roller 35 is provided on the inner surface of the battery compartment 2 corresponding to the first conveying roller 43, and a positioning member 42 is fixedly provided on the surface of the support plate 41 on one side of the first conveying roller 43.

[0031] Working principle: When using the intelligent battery exchange cabinet of the present invention that is convenient for taking and placing energy storage batteries to take and place the energy storage batteries 3 therein, relevant personnel can perform the taking and replacing operations through the control panel 10 on the battery exchange cabinet 1.

[0032] It should be noted that the battery swap cabinet 1 has a built-in controller and is connected to the control screen 10. The control screen 10 is touch-sensitive and can control the various components of the battery swap cabinet 1, as well as understand the status of the energy storage batteries 3 in each battery compartment 2 in the battery swap cabinet 1. The operation of removing the energy storage battery 3 can be pre-programmed. The control screen 10, as a trigger end, can automatically drive the corresponding preset program to realize the removal of the energy storage battery 3.

[0033] It should be further explained that the control method of the present application can be automatically controlled by a controller, and the control circuit of the controller can be implemented by simple programming by technicians in this field, which is common knowledge in this field. In addition, the present application is mainly used to protect mechanical devices, so the control method and circuit connection will not be explained in detail in this application.

[0034] When the energy storage battery 3 needs to be placed in the battery compartment 2, the relevant personnel put the energy storage battery 3 on the surface of the first conveying roller 43 on the pallet 41, and make one end of the energy storage battery 3 rest against the positioning piece 42. Then the relevant personnel operate the control screen 10 to make the controller control the lifting assembly 5 to operate, so that the lifting motor 6 raises the lifting plate 9 on the platform 11 through the lifting screw 8 until it reaches the designated battery compartment 2. Then the controller starts the pushing motor 37 to drive the pushing screw 38 to rotate, and drives the moving part 13 to move toward the opening of the battery compartment 2. In this process, the cooperation between the pulling plate 14 and the pushing plate 20 and the buffer spring 45 set between the moving part 13 and the docking plate 18 act Under the action of the expansion spring 26, the centering slider 28 drives the centering clamp 29 to expand to both sides, and reaches both sides of the energy storage battery 3 as the pulling plate 14 does. At this time, the surface of the push plate 20 abuts against the energy storage battery 3, and when the pulling plate 14 extends from the battery compartment 2, the bottom of the grabbing card 17 installed at its end is impacted by the energy storage battery 3 and rotates and is stored in the storage groove 16 until it reaches one end of the energy storage battery 3 and then automatically expands under the action of the torsion spring (such as Figure 7 As shown), the pushing motor 37 then drives the pushing screw 38 in reverse to control the retraction of the grabbing assembly 4. At this time, the pulling plate 14 moves into the battery compartment 2, and the unfolded grabbing card 17 moves with it until it abuts against the end of the energy storage battery 3 to achieve grabbing, and the energy storage battery 3 is dragged down by the pulling plate 14 and then enters the battery compartment 2 under the cooperation of the first conveying roller 43 and the second conveying roller 35 in the battery compartment 2. In this process, due to the grabbing and dragging of one end of the energy storage battery 3, the other end of the energy storage battery 3 abuts against the pushing plate 20 as it moves, so that the energy storage battery 3 drives the pushing plate 20 to move toward the inside of the battery compartment 2, and As the push plate 20 moves inward and drives the centering clamp 21 to retract, it is again squeezed by the inner wall of the battery compartment 2 to center and shrink, so that the centering clamps 29 on both sides squeeze the dragged energy storage battery 3 to center and calibrate it so that the socket 44 at one end of the energy storage battery 3 is aligned with the plug 34 on the charging module 32. Under the drag of the grabbing component 4, the plug 34 is plugged into the socket 44 to realize the docking of the energy storage battery 3 and the charging module 32. In this process, the extension part 33 on the charging module 32 passes through the docking port 22 on the surface of the push plate 20 so that the plug 34 and the socket 44 are smoothly docked (as shown in FIG. Figure 6 As shown), the process of installing the energy storage battery 3 into the power exchange cabinet 1 is completed; When the energy storage battery 3 needs to be taken out of the battery compartment 2, the lifting plate 9 is similarly moved to the designated battery compartment 2 by the lifting assembly 5, and then the pushing screw 38 is driven to rotate by the pushing motor 37 again to drive the moving part 13 to move toward the opening of the battery compartment 2. During this process, the moving part 13 pushes the docking plate 18 outward through the buffer spring 45, and then drives the pushing plate 20 to push the docked energy storage battery 3 outward, so that the energy storage battery 3 is separated from the charging module 32 and moves outward until it is pushed by the pushing plate 20 to the corresponding supporting plate 41 on the lifting plate 9 (see Figure 7 and Figure 1 ), then the lifting plate 9 can be lowered by the lifting assembly 5 to obtain the energy storage battery 3. In the embodiment of the present application, the adjacent sides of the lifting plate 9 and the battery compartment 2 are provided with positioning sensors and in-place detection sensors (which are common means in this field, common knowledge, and will not be described in detail) to ensure that the lifting plate 9 is accurately docked with the designated battery compartment 2.

[0035] In summary, the present invention provides an intelligent battery exchange cabinet that facilitates the removal and placement of energy storage batteries: the lifting assembly controls the lifting plate to lift the energy storage battery to the designated battery compartment instead of manually lifting it, which can effectively save manpower and avoid the risk of slipping out of the hands. Moreover, the grabbing assembly provided in the battery compartment cooperates with the centering assembly to automatically grab the energy storage battery on the lifting plate and move it into the battery compartment for automatic docking, without the need for manual alignment and insertion, which greatly reduces the operational difficulty of using the energy storage battery and makes it simple and quick to use for groups with weaker strength. The grabbing assembly composed of a pull plate, a moving part and a grabbing card can be freely moved from the battery compartment with the cooperation of a push screw. The grabbing card, which is elastically unfolded by a torsion spring, can rotate into the storage slot under the resistance of the energy storage battery when grabbing the energy storage battery, until it automatically unfolds after reaching one end of the energy storage battery. The energy storage battery can be dragged into the battery compartment by the grabbing card under the drag of the pull plate, thereby realizing automatic grabbing of the energy storage battery. The centering assembly, consisting of a push plate and a centering clamp, can dynamically cooperate with the gripping assembly. After the energy storage battery enters the battery compartment, the centering assembly can cause the inclined guide portion of the elastically expanded centering clamp to contract in conjunction with the guide roller under the pressure of the inner wall of the battery compartment, thereby centering and squeezing the symmetrically arranged centering clamps. The centering clamp of the moving energy storage battery is calibrated so that the energy storage battery can finally and accurately dock with the charging module under the drag of the gripping assembly, realizing fully automatic lifting, gripping, and docking of the energy storage battery. When the energy storage battery is pushed out of the battery compartment, the lifting assembly is also pushed by the gripping assembly to move, causing the push plate to push the energy storage battery outward and separate it from the charging module until it reaches the outer tray, effectively realizing the smooth removal of the energy storage battery from the battery swap cabinet.
