Description

Technical Field

[0001] This utility model relates to the field of energy storage cabinet technology, specifically a battery charging interface self-locking plug-in energy storage cabinet. Background Technology

[0002] In current energy storage technology applications, energy storage cabinets, as key equipment for storing electrical energy, play a vital role in balancing grid supply and demand, improving energy utilization efficiency, and responding to sudden power outages. They are widely used in renewable energy systems, microgrids, emergency power supplies, and power system dispatching. During the operation of an energy storage cabinet, the battery charging process is fundamental to ensuring its normal operation and maintaining energy reserves.

[0003] Existing battery charging methods for energy storage cabinets mostly involve inserting the battery into the cabinet, aligning the battery's charging port with the cabinet's charging interface, and then inserting it to complete the connection and begin charging. However, in practical use, this simple connection method has revealed some problems. Firstly, during charging, due to the lack of additional securing measures and relying solely on the physical connection of the interface, if the energy storage cabinet experiences vibration, impact, or is accidentally touched or moved, the battery may be accidentally pulled out of the cabinet. Once the battery detaches from the cabinet midway through charging, the charging process is forced to stop, not only failing to achieve the expected charging effect and resulting in insufficient battery charge storage, affecting subsequent use, but also potentially damaging the battery's lifespan.

[0004] Therefore, a self-locking plug-in energy storage cabinet with a battery charging interface is proposed. Utility Model Content

[0005] The purpose of this utility model is to provide a self-locking plug-in energy storage cabinet with a battery charging interface to solve the problems mentioned in the background art.

[0006] To achieve the above objectives, the present invention provides the following technical solution: a battery charging interface self-locking plug-in energy storage cabinet, including a cabinet body, an installation frame inside the cabinet body, the installation frame including multiple side plates and multiple back plates, multiple bottom plates on the side plates, an installation plate slidably mounted on the bottom plates, a transmission mechanism on the side of the installation plate near the back plate, multiple clamping mechanisms connected to the transmission mechanism, and the clamping mechanisms located on both sides of the installation plate;

[0007] The transmission mechanism is also equipped with a locking mechanism, and a square locking tube is provided on the back plate. The locking mechanism and the square locking tube are detachably connected.

[0008] The base plate is provided with a guide mechanism, which includes multiple guide plates. The multiple guide plates are located on both sides of the clamping mechanism, and the guide plates and the sides of the clamping mechanism form a pressing fit, so that the clamping mechanism clamps the battery.

[0009] Preferably, the transmission mechanism includes a fixed rod, a transmission gear, a rack one, and a rack two;

[0010] A fixing rod is provided on the side of the mounting plate near the back plate. The transmission gear is rotatably mounted on the fixing rod. Rack 1 and rack 2 are slidably mounted on the mounting plate. Rack 1 is located above the fixing rod, and rack 2 is located below the fixing rod. Both rack 1 and rack 2 are meshed with the transmission gear.

[0011] Preferably, the clamping mechanism is provided in two sets, and the clamping mechanism includes a locking clamp and a limiting plate;

[0012] The limiting plate is fixed to the end of the locking clamp away from the mounting plate;

[0013] One set of clamping mechanisms is connected to the end of rack one away from the transmission gear, and the other set of clamping mechanisms is connected to the end of rack two away from the transmission gear.

[0014] Preferably, the locking mechanism includes a connecting rod, a locking frame, and a locking block;

[0015] The locking block is fixed to the locking frame;

[0016] The upper ends of the two connecting rods are respectively connected to rack one and rack two, and the lower ends of the two connecting rods are respectively connected to the two locking frames;

[0017] Limiting holes are provided on both sides of the square locking tube, and the locking block is inserted into the limiting holes to form a self-locking mechanism.

[0018] The mounting plate is equipped with a release spring, one end of which is connected to the mounting plate and the other end of which is connected to the locking clamp.

[0019] Preferably, the base plate is provided with a guide groove, and the mounting plate is slidably connected to the base plate through the guide groove.

[0020] Preferably, the mounting plate is provided with an unlocking mechanism, which includes a limiting rod, a limiting frame, a rotating rod, a second bevel gear, a lever, a driving rod, a third bevel gear, a fourth bevel gear, and a first bevel gear.

[0021] The limiting rod is set on the side of the mounting plate near the back plate, and the limiting frame is set on the top of the mounting plate;

[0022] The rotating rod is rotatably mounted on the limiting frame. A bevel gear is provided at the end of the rotating rod near the back plate, and a lever is provided at the end of the rotating rod away from the back plate.

[0023] The drive rod is rotatably mounted on the limit rod. A bevel gear four is provided at the end of the drive rod near the bottom plate, and a bevel gear three is provided at the end of the drive rod away from the bottom plate. The bevel gear three meshes with the bevel gear two.

[0024] The first bevel gear is fixedly connected to the transmission gear and arranged coaxially, and the first bevel gear meshes with the fourth bevel gear.

[0025] Compared with existing technologies, the advantages of this invention are as follows: This solution forms protection through the synergistic action of the clamping mechanism and the locking mechanism. When the battery is being charged, the guide plate presses against the locking plate of the clamping mechanism, achieving stable clamping from both sides of the battery; simultaneously, the transmission mechanism links with the locking mechanism, causing the locking frame to insert into the square locking tube, and the locking block to embed into the limiting hole to form a self-locking mechanism, while the separation spring continuously applies pressure to ensure the stable limiting of the locking block. In addition, the limiting plate integrated with the locking plate fits against the rear end of the battery, restricting the battery's forward and backward movement. Even if the energy storage cabinet encounters vibration, collision, or accidental contact, the battery cannot detach from the cabinet, completely avoiding the problem of charging interruption, ensuring that the battery completes charging as expected, and reducing the damage to the battery's cycle life caused by frequent interruptions.

[0045] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0046] Please see Figures 1 to 10 This utility model provides an embodiment of a self-locking plug-in energy storage cabinet for battery charging interfaces, comprising a cabinet body 1, an installation frame 10 inside the cabinet body 1, the installation frame 10 including multiple side plates 11 and multiple back plates 12, and multiple base plates 13 on the side plates 11. A charging socket 122 is installed on the back plate 12, and the battery is placed on the base plate 13. The battery is equipped with a charging port. The battery is pushed towards the charging socket 122 along the direction of the base plate 13, so that the charging port of the battery engages with the charging socket 122, allowing the battery to be charged.

[0047] The mounting plate 2 has a charging hole through which the battery charging port can pass and connect with the charging socket 122 on the back plate 12.

[0048] A mounting plate 2 is slidably mounted on the base plate 13. A limiting slider 21 is installed at the bottom of the mounting plate 2. The mounting plate 2 slides on the base plate 13 through the cooperation of the limiting slider 21 and the guide groove 131. A transmission mechanism 4 is provided on the side of the mounting plate 2 near the back plate 12. Multiple clamping mechanisms 5 are connected to the transmission mechanism 4, and the clamping mechanisms 5 are located on both sides of the mounting plate 2. The clamping mechanisms 5 clamp the battery from both sides to prevent the battery from being accidentally pulled out of the energy storage cabinet during the battery charging process.

[0049] The transmission mechanism 4 is also provided with a locking mechanism 6, and the back plate 12 is provided with a square locking tube 121. The locking mechanism 6 and the square locking tube 121 are detachably connected. Specifically, the detachable connection between the locking mechanism 6 and the square locking tube 121 is that the locking block 612 of the locking mechanism 6 cooperates with the limiting holes 1211 on both sides of the square locking tube 121. The locking block 612 is inserted into the limiting hole 1211 to form a self-locking mechanism.

[0050] A guide mechanism 3 is provided on the base plate 13. The guide mechanism 3 includes multiple guide plates 31, which are located on both sides of the clamping mechanism 5. The guide plates 31 and the sides of the clamping mechanism 5 form a pressing fit, so that the clamping mechanism 5 clamps the battery.

[0051] The guide plate 31 is narrow on the outside and wide on the inside. The outer part of the guide plate 31 is the end away from the back plate 12, and the inner part is the end closer to the back plate 12. The transition area from the outer part (away from the back plate 12) to the inner part (closer to the back plate 12) of the guide plate 31 is an arc. This arc ensures a smooth pressing fit between the guide plate 31 and the side of the clamping mechanism 5, preventing jamming when the clamping mechanism 5 slides from the outside to the inside of the guide plate 31.

[0052] Specifically, the transmission mechanism 4 includes a fixed rod 41, a transmission gear 42, a rack 43, and a rack 44;

[0053] A fixing rod 41 is provided on the side of the mounting plate 2 near the back plate 12. The transmission gear 42 is rotatably mounted on the fixing rod 41. Rack 1 43 and rack 2 44 are slidably mounted on the mounting plate 2. Rack 1 43 is located above the fixing rod 41, and rack 2 44 is located below the fixing rod 41. Both rack 1 43 and rack 2 44 are meshed with the transmission gear 42.

[0054] Specifically, the clamping mechanism 5 is provided in two sets, and the clamping mechanism 5 includes a locking clamping plate 51 and a limiting plate 52;

[0055] The limiting plate 52 is fixed to the end of the locking clamp 51 away from the mounting plate 2. The limiting plate 52 and the locking clamp 51 are integrally set. When the locking clamp 51 clamps the battery, the limiting plate 52 is in contact with the side of the battery away from the back plate 12. When the environment in which the energy storage cabinet is located is subject to vibration, collision, or accidental contact or movement, the limiting plate 52 limits the battery, and the battery will not be accidentally pulled out of the energy storage cabinet.

[0056] One set of clamping mechanisms 5 is connected to the end of rack 43 away from the transmission gear 42, and the other set of clamping mechanisms 5 is connected to the end of rack 44 away from the transmission gear 42.

[0057] Specifically, the locking mechanism 6 includes a connecting rod 61, a locking frame 611, and a locking block 612;

[0058] Lock block 612 is fixed to locking frame 611;

[0059] The upper ends of the two connecting rods 61 are connected to rack 43 and rack 44 respectively, and the lower ends of the two connecting rods 61 are connected to two locking frames 611 respectively. The locking mechanism 6 is configured in two sets, one set of locking mechanism 6 follows the movement of rack 43, and the other set of locking mechanism 6 follows the movement of rack 44. The two sets of locking mechanisms 6 follow the movement of rack 43 and rack 44 to complete the unlocking.

[0060] Limiting holes 1211 are provided on both sides of the square locking tube 121, and the locking block 612 is inserted into the limiting holes 1211 to form a self-locking mechanism.

[0061] A separation spring 22 is provided on the mounting plate 2. One end of the separation spring 22 is connected to the mounting plate 2, and the other end of the separation spring 22 is connected to the locking clamp 51.

[0062] Specifically, the base plate 13 is provided with a guide groove 131, and the mounting plate 2 is slidably connected to the base plate 13 through the guide groove 131.

[0063] When a user wants to start charging the battery, they align the battery's charging port with the charging hole on the mounting plate 2 and push the battery toward the back plate 12 so that the battery's charging port passes through the charging hole.

[0064] After the battery charging port passes through the charging hole, it continues to push the battery towards the back plate 12. A separation spring 22 is positioned between the mounting plate 2 and the locking clamp 51, initially keeping them separated. As the battery slides, the locking clamp 51, guided and compressed by the guide plate 31, overcomes the elastic force of the separation spring 22, gradually moving closer to the battery and clamping it. Since the two clamping mechanisms 5 are respectively connected to rack 43 and rack 44 of the transmission mechanism 4, when the two locking clamps 51 move closer to the battery, they simultaneously drive rack 43 and rack 44 to move closer together. When rack 43 and rack 44 approach each other, they will respectively drive the two locking mechanisms 6 to move closer together.

[0065] Under the pressure of the guide plate 31, the two sets of clamping mechanisms 5 drive the locking frames 611 of the corresponding locking mechanisms 6 to move closer to each other, so that the locking frames 611 are aligned with the square locking tube 121, ensuring that the two sets of locking mechanisms 6 can be inserted into the square locking tube 121.

[0066] Once the locking frame 611 is aligned with the square locking tube 121, the battery is pushed further, causing the locking frame 611 to enter the square locking tube 121. After the locking frame 611 enters the square locking tube 121, it will cause the locking block 612 to embed into the limiting hole 1211 on the square locking tube 121. During the process of the locking block 612 embedding into the limiting hole 1211, the release spring 22 pushes the locking clamp 51 to fit against the inner wall of the square locking tube 121. This fitting action simultaneously pushes the locking block 612 on the locking frame 611 to embed into the limiting hole 1211. After the locking block 612 is embedded into the limiting hole 1211, the release spring 22 will continue to push the locking clamp 51 to drive the locking block 612 into the limiting hole 1211. At this time, the battery is restricted by the limiting plate 52, and the locking clamp 51, which is integrated with the limiting plate 52, is limited by the locking mechanism 6, so that the locking clamp 51 cannot be pulled out from the cabinet 1, thereby locking the battery inside the cabinet 1 through the limiting plate 52.

[0067] Specifically, the mounting plate 2 is provided with an unlocking mechanism 7, which includes a limit rod 710, a limit frame 720, a rotating rod 730, a second bevel gear 731, a paddle block 732, a drive rod 740, a third bevel gear 741, a fourth bevel gear 742, and a first bevel gear 750.

[0068] The limiting rod 710 is set on the side of the mounting plate 2 near the back plate 12, and the limiting frame 720 is set on the top of the mounting plate 2;

[0069] The rotating rod 730 is rotatably mounted on the limiting frame 720. A bevel gear 731 is provided at the end of the rotating rod 730 near the back plate 12, and a lever 732 is provided at the end of the rotating rod 730 away from the back plate 12.

[0070] The drive rod 740 is rotatably mounted on the limit rod 710. A bevel gear 742 is provided at the end of the drive rod 740 near the base plate 13, and a bevel gear 741 is provided at the end of the drive rod 740 away from the base plate 13. The bevel gear 741 meshes with the bevel gear 731.

[0071] The first bevel gear 750 is fixedly connected to the transmission gear 42 and arranged coaxially, and the first bevel gear 750 meshes with the fourth bevel gear 742.

[0072] When the self-locking mechanism needs to be unlocked, the user rotates the rotating rod 730 of the unlocking mechanism 7 from the outside of the cabinet 1. The user rotates the lever 732 to make the rotating rod 730 rotate. After the rotating rod 730 rotates, it drives the second bevel gear 731 to rotate. Because the second bevel gear 731 meshes with the third bevel gear 741, the second bevel gear 731 will drive the third bevel gear 741 to rotate. Because the third bevel gear 741 is connected to the fourth bevel gear 742 through the drive rod 740, the rotation of the third bevel gear 741 will drive the fourth bevel gear 742 to rotate. And because the fourth bevel gear 742 meshes with the first bevel gear 750, the rotation of the fourth bevel gear 742 will drive the first bevel gear 750 to rotate.

[0073] The bevel gear 750 is fixedly connected to and coaxially arranged with the transmission gear 42. Rotation of the bevel gear 750 drives the transmission gear 42 to rotate. When the user rotates the rotating rod 730 from outside the cabinet 1, the transmission action between the bevel gear set and the transmission gear 42 causes racks 43 and 44 to move closer together, thereby causing the two sets of locking frames 611 to move closer together. The locking block 612 on the locking frame 611 disengages from the limiting hole 1211 as the two sets of locking frames 611 move closer. At this time, the user pulls out the battery away from the back panel 12, allowing the locking frame 611 of the self-locking mechanism to disengage from the square locking tube 121, thus unlocking the battery.

[0074] Working principle:

[0075] Users must first confirm that the energy storage cabinet is in a power-off standby state, then take out the battery to be charged, observe the position of the battery charging port, align it with the charging hole opened on the mounting plate 2, and ensure that the axes of the two are aligned to prepare for subsequent plugging.

[0076] The user slowly pushes the battery toward the back plate 12 along the guide direction of the base plate 13, so that the battery charging port passes through the charging hole on the mounting plate 2. During this process, the pushing force should be kept steady to avoid damage to the charging port or charging hole due to excessive force, until the front end of the charging port makes initial contact with the charging socket 122 on the back plate 12.

[0077] The user continues to push the battery towards the back plate 12, ensuring the charging port is fully aligned with the charging socket 122. Simultaneously, the clamping mechanisms 5 on both sides of the mounting plate 2, guided by the arc transition of the guide plate 31, overcome the initial elasticity of the separation spring 22 and gradually move closer to the battery side. Since the two clamping mechanisms 5 are respectively connected to rack 43 and rack 44 of the transmission mechanism 4, the approach of the clamping mechanisms 5 will synchronously drive rack 43 and rack 44 to move relative to each other towards the transmission gear 42.

[0078] As rack 43 and rack 44 move relative to each other, the two sets of locking mechanisms 6 move synchronously toward the square locking tube 121 on the back plate 12 until the locking frame 611 and the axis of the square locking tube 121 are aligned. Continuing to push the battery causes the locking frame 611 to fully enter the square locking tube 121. At this point, the release spring 22 resets, pushing the locking clamp 51 to fit against the inner wall of the square locking tube 121. This fitting action causes the locking block 612 on the locking frame 611 to embed into the limiting holes 1211 on both sides of the square locking tube 121, forming a self-locking mechanism.

[0079] Once the locking block 612 is fully inserted into the limiting hole 1211, the separating spring 22 continuously applies pressure to ensure that the locking block 612 is stably limited. At the same time, the limiting plate 52 of the clamping mechanism 5 is fully engaged with the side of the battery away from the back plate 12, restricting the battery from moving back and forth. At this time, the battery is doubly locked (the locking mechanism 6 limits the locking clamp 51, and the limiting plate 52 limits the battery), and the user can turn on the power supply of the energy storage cabinet to start normal charging.

[0080] When a user wants to unlock the device, they should first turn off the charging power of the energy storage cabinet to ensure that the battery has stopped charging and avoid safety hazards caused by operating the device while it is powered on.

[0081] The user locates the lever 732 of the unlocking mechanism 7 from outside the cabinet 1 and rotates the lever 732 clockwise or counterclockwise by hand (the specific direction is subject to the actual markings on the device), causing the rotating rod 730 to rotate synchronously. The bevel gear 731 at one end of the rotating rod 730 meshes with the bevel gear 741 on the drive rod 740, thereby driving the drive rod 740 and the bevel gear 742 at its lower end to rotate; the bevel gear 742 meshes with the bevel gear 750 coaxial with the transmission gear 42, ultimately driving the transmission gear 42 to rotate.

[0082] When the transmission gear 42 rotates, it drives rack 43 and rack 44 to move in opposite directions. The two sets of clamping mechanisms 5 separate to both sides synchronously with the racks, and at the same time drive the locking frames 611 of the corresponding locking mechanisms 6 to move closer to each other, so that the locking block 612 disengages from the limiting hole 1211 of the square locking tube 121 and releases the self-locking state.

[0083] Once the locking block 612 is completely disengaged from the limiting hole 1211, the user slowly pulls out the battery away from the back plate 12. The mounting plate 2 slides synchronously along the guide groove 131 of the base plate 13, and the charging port gradually separates from the charging socket 122. After the charging port is completely disengaged from the charging hole on the mounting plate 2, the battery can be removed, completing the power extraction operation.

[0084] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.
