Description

Technical Field

[0001] This utility model belongs to the field of energy storage cabinet technology, and in particular relates to the battery compartment structure of a drawer-type energy storage cabinet. Background Technology

[0002] With the booming development of the new energy industry, energy storage technology has become a key link in ensuring stable power supply and improving energy efficiency. Drawer-type energy storage cabinets are widely used in distributed energy storage, grid peak shaving, and industrial energy storage scenarios due to their convenient battery installation and maintenance characteristics. By modularly integrating batteries into the drawer-type structure, it facilitates battery replacement and maintenance, and improves the flexibility and scalability of the energy storage system.

[0003] Currently available energy storage cabinets lack automated clamping and adjustment devices for battery loading, unloading, and position adjustment. Manual operation is not only inefficient but also poses safety hazards when handling heavy batteries. Traditional battery compartments mostly require manual dragging of batteries from the charging position. Due to the weight of the batteries themselves, this operation method not only consumes a lot of manpower and is inefficient, but also easily causes batteries to slip or bump during dragging, resulting in damage to the battery casing or even internal circuit failure, increasing battery wear and maintenance costs.

[0004] To address these issues, we have developed a drawer-type energy storage cabinet battery compartment structure. Utility Model Content

[0005] The purpose of this utility model is to provide a battery compartment structure for a drawer-type energy storage cabinet. Through the cooperation of the adjustment mechanism, the clamping mechanism and the charging station components, it solves the problem that existing energy storage cabinets lack automated clamping and adjustment devices for battery loading, unloading and position adjustment, resulting in low efficiency of manual operation.

[0006] To solve the above-mentioned technical problems, this utility model is achieved through the following technical solution.

[0007] This utility model relates to a battery compartment structure for a drawer-type energy storage cabinet, including a base plate. An adjustment mechanism is fixedly connected to the front end of the top of the base plate, and a clamping mechanism is fixedly connected to the top of the adjustment mechanism. A charging station assembly is fixedly connected to the rear end of the top of the base plate. The charging station assembly includes a charging cabinet, the bottom of which is fixedly connected to the base plate. A placement groove is formed on the surface of the charging cabinet, and a mounting frame is provided within the inner cavity of the placement groove. A fixing frame is fixedly connected to one side of the inner cavity of the placement groove, and a first electric push rod is fixedly connected to one side of the fixing frame. A connecting block is fixedly connected to one side of the first electric push rod, and one side of the connecting block is fixedly connected to the mounting frame. A battery assembly is located on the top of the mounting frame. The charging cabinet and the base plate are connected by screws. Securely fastened to ensure stable installation, the charging cabinet surface features multiple placement slots, the dimensions of which are standardized according to common battery specifications. The mounting frame adopts a frame structure with excellent load-bearing capacity. The top of the mounting frame is used to place the battery assembly, which includes the battery body and a matching charging interface module. The charging interface module is connected to the charging circuit inside the charging cabinet via a pluggable connector for easy installation and removal. The first electric push rod realizes the battery delivery function, significantly improving the automation and intelligence level of the battery compartment structure. During the battery replacement process, the first electric push rod can quickly deliver the battery, and then, in conjunction with the adjustment mechanism and clamping mechanism, the old battery can be quickly removed and the new battery installed, greatly shortening the battery replacement time.

[0008] The present invention is further configured such that the adjustment mechanism includes a housing, the bottom of which is fixedly connected to one side of the top of the base plate. A first motor is fixedly connected to the bottom of the inner cavity of the housing, and a first threaded rod is fixedly connected to the output end of the first motor. A threaded sleeve is threadedly connected to the surface of the first threaded rod, and one side of the threaded sleeve extends through to the outside of the housing and is fixedly connected to a lifting platform. A translation mechanism is fixedly connected to the inner cavity of the lifting platform. The first motor drives the first threaded rod to rotate, and the threaded sleeve moves vertically along the first threaded rod, thereby driving the lifting platform to rise and fall smoothly. This allows the clamping mechanism to be height-adjusted in the vertical direction to adapt to the battery loading and unloading needs at different heights, greatly enhancing the adaptability of the battery compartment to different battery specifications and different installation positions. It effectively avoids the situation where batteries cannot be loaded and unloaded normally due to height mismatch, and significantly improves the flexibility and versatility of the battery compartment.

[0009] The present invention is further configured such that the translation mechanism includes a second motor, one side of which is fixedly connected to the inner wall of the lifting platform, and the output end of the second motor is fixedly connected to a second threaded rod. A movable seat is threadedly connected to the surface of the second threaded rod. The second motor drives the second threaded rod to rotate, and the second threaded rod drives the movable seat to move linearly in the horizontal direction. This translation mechanism, combined with the lifting platform in the adjustment mechanism, gives the clamping mechanism the ability to move freely in the horizontal direction, thereby realizing the flexible movement of the clamping mechanism in a two-dimensional plane. Whether it is transferring batteries between different placement slots in the charging cabinet or performing precise positioning during battery replacement, the translation mechanism can ensure that the clamping mechanism reaches the target position.

[0010] The present invention is further configured such that the clamping mechanism includes a bracket, the bottom of the bracket is fixedly connected to a movable seat, a third motor is fixedly connected to both sides of the inner cavity of the bracket, a gear is fixedly connected to the output end of the third motor, and a clamping mechanism is provided on both sides of the inner cavity of the bracket. The third motor drives the gear to rotate, and the toothed plate meshing with the gear drives the clamping plate to move. At the same time, the second electric push rod drives the clamping block to fasten the battery, preventing the battery from slipping or shifting during transportation.

[0011] The present invention is further configured such that the clamping mechanism includes a clamping plate disposed on both sides of the inner cavity of the bracket. A second electric push rod is fixedly connected to the front end and rear end of one side of the clamping plate. A clamping block is fixedly connected to one side of the second electric push rod. A toothed plate is fixedly connected to one side of the clamping plate. The toothed plate meshes with a gear. The clamping plate moves horizontally under the drive of a third motor through the meshing of the toothed plate and the gear. It can automatically adjust the clamping distance according to the size of the battery to adapt to batteries of different specifications. The setting of the second electric push rod and the clamping block further enhances the clamping effect.

[0012] The present invention is further provided that the top of the charging cabinet is provided with a ventilation slot, and a protective frame is fixedly connected to the top of the charging cabinet. The ventilation slot can form a good air convection channel. During the battery charging process, the ventilation slot can dissipate the generated heat in time, accelerate air circulation, and improve heat dissipation efficiency.

[0013] The present invention is further configured such that a sliding groove is provided on one side of the inner cavity of the placement slot, and a slider that cooperates with the sliding groove is fixedly connected to one side of the mounting bracket. The sliding groove and the slider cooperate with each other to form a sliding guide structure, which ensures the stability of the mounting bracket during the translation process.

[0014] The present invention is further configured such that a cooling radiator is fixedly connected to the bottom of the rear end of the charging cabinet, and a maintenance plate is provided at the bottom of the rear end of the charging cabinet and at the front end of the cooling radiator. The cooling radiator can actively and forcibly cool the heat generated during battery charging, ensuring that the battery can maintain normal normal performance in high-temperature environments and effectively extend the battery's service life.

[0015] The present invention has the following beneficial effects.

[0016] 1. This utility model uses a first motor to drive a first threaded rod to rotate, which in turn drives a threaded sleeve and a lifting platform to achieve lifting and lowering movements. A second motor drives a moving seat to move horizontally through a second threaded rod. In conjunction with a third motor in the clamping mechanism, the gears rotate, enabling the toothed plate and clamping mechanism to accurately clamp and adjust the position of the battery. The entire automated device replaces traditional manual operation, which can quickly complete the handling, installation and disassembly of batteries, greatly improves work efficiency, reduces the safety risks of manual operation, and ensures the accuracy of battery installation position.

[0017] 2. When the battery needs to be replaced, this utility model only requires issuing a command to start the first electric push rod, which pushes the mounting bracket and battery assembly along the slide in the placement slot to quickly move them out of the charging cabinet. There is no need for manual dragging. Compared with traditional manual operation, the time to remove the battery is greatly shortened, and the overall efficiency of battery replacement is significantly improved.

[0033] Example 2

[0034] Please see Figure 1-9 Based on Embodiment 1, the adjusting mechanism 2 includes a housing 21. The bottom of the housing 21 is fixedly connected to one side of the top of the base plate 1. A first motor 22 is fixedly connected to the bottom of the inner cavity of the housing 21. A first threaded rod 23 is fixedly connected to the output end of the first motor 22. A threaded sleeve 24 is threadedly connected to the surface of the first threaded rod 23. One side of the threaded sleeve 24 extends through to the outside of the housing 21 and is fixedly connected to a lifting platform 25. A translation mechanism 26 is fixedly connected to the inner cavity of the lifting platform 25. The translation mechanism 26 includes a second motor 261.

A movable seat 263 is threadedly connected to the surface of the second threaded rod 262. The clamping mechanism 3 includes a bracket 31. The bottom of the bracket 31 is fixedly connected to the movable seat 263. A first threaded rod 262 is fixedly connected to both sides of the inner cavity of the bracket 31. The output end of the third motor 32 is fixedly connected to a gear 33. Clamping mechanisms 34 are provided on both sides of the inner cavity of the bracket 31. Each clamping mechanism 34 includes a clamping plate 341, which is located on both sides of the inner cavity of the bracket 31. A second electric push rod 342 is fixedly connected to the front and rear ends of one side of the clamping plate 341. A clamping block 343 is fixedly connected to one side of the second electric push rod 342. A toothed plate 344 is fixedly connected to one side of the clamping plate 341, meshing with the gear 33. A ventilation slot 5 is provided on the top of the charging cabinet 41. A protective frame 6 is fixedly connected to the top of the charging cabinet 41. A sliding groove is provided on one side of the inner cavity of the placement slot 42. A slider 7, which works with the sliding groove, is fixedly connected to one side of the mounting frame 43. A cooling radiator 8 is fixedly connected to the bottom of the rear end of the charging cabinet 41. A maintenance plate 9 is provided at the bottom of the rear end of the charging cabinet 41 and at the front end of the cooling radiator 8.

[0035] Specifically: The first motor 22 drives the first threaded rod 23 to rotate, and the threaded sleeve 24 moves vertically along the first threaded rod 23, thereby driving the lifting platform 25 to rise and fall smoothly. This allows the clamping mechanism 3 to be height-adjusted in the vertical direction to adapt to the battery loading and unloading needs at different heights, greatly enhancing the battery compartment's adaptability to different battery specifications and installation positions. It effectively avoids situations where batteries cannot be properly loaded or unloaded due to height mismatch, significantly improving the flexibility and versatility of the battery compartment. The second motor 261 drives the second threaded rod 262 to rotate, and the second threaded rod 262 drives the moving seat 263 to move linearly in the horizontal direction. This translation mechanism 26, combined with the lifting platform 25 in the adjustment mechanism 2, gives the clamping mechanism 3 the ability to move freely in the horizontal direction, thus realizing flexible movement of the clamping mechanism 3 in a two-dimensional plane. Whether transferring batteries between different placement slots 42 in the charging cabinet 41 or positioning during battery replacement, the translation mechanism 26 ensures that the clamping mechanism 3 reaches the target position. The third motor 32 drives the gear 33 to rotate. The toothed plate 344, which meshes with the gear 33, drives the clamping plate 341 to move in and out inside the bracket 31. At the same time, the second electric push rod 342 drives the clamping block 343 to secure the battery, preventing the battery from slipping or shifting during transportation. The clamping plate 341 moves horizontally under the drive of the third motor 32 through the meshing of the toothed plate 344 and the gear 33. It can automatically adjust the clamping distance according to the size of the battery to adapt to different battery specifications. The setting of the second electric push rod 342 and the clamping block 343 further enhances the clamping effect. The ventilation slot 5 can form a good air convection channel. During the battery charging process, the ventilation slot 5 can dissipate the generated heat in time, accelerate air circulation, and improve heat dissipation efficiency. The sliding groove and the slider 7 cooperate to form a sliding guide structure, ensuring the stability of the mounting bracket 43 during the horizontal movement. The cooling radiator 8 can actively and forcibly cool the heat generated during the battery charging process, ensuring that the battery can maintain normal normal performance in high-temperature environments and effectively extend the battery's service life.

[0036] The working principle of this utility model is as follows: when it is necessary to remove the battery from the placement slot 42, the first electric push rod 45 is energized and performs a retraction action, pulling the connecting block 46 to drive the mounting bracket 43 and the top battery assembly 47 to slide smoothly outward from the inside of the placement slot 42 along the sliding groove on one side of the inner cavity of the placement slot 42.

[0037] After the first electric push rod 45 pushes the battery assembly 47 to the appropriate position, the first motor 22 drives the first threaded rod 23 to rotate, and the threaded sleeve 24 moves vertically along the first threaded rod 23, thereby driving the lifting platform 25 fixed on one side to rise and fall smoothly, adjusting the clamping mechanism 3 to the same height position as the battery being pushed out.

[0038] At the same time, the second motor 261 drives the second threaded rod 262 to rotate, which in turn drives the moving seat 263 to move linearly in the horizontal direction. Through the coordinated control of the first motor 22 and the second motor 261, the clamping mechanism 3 moves precisely in three-dimensional space and quickly positions itself in front of the battery pushed out from the placement slot 42.

[0039] After the clamping mechanism 3 reaches the target position, the third motor 32 starts and drives the gear 33 to rotate. The toothed plate 344, which meshes with the gear 33, moves the clamping plate 341 between the battery assembly 47 and the side wall of the mounting bracket 43. The second electric push rod 342 extends to clamp and reinforce the battery assembly 47. Then, the third motor 32 rotates in the opposite direction to reset and moves the clamping plate 341 into the bracket 31 to achieve stable clamping of the battery. After successfully clamping the battery, the adjusting mechanism 2 and the translation mechanism 26 work together again to transport the battery to the designated position according to the planned path, completing the entire operation process of taking the battery out of the placement slot 42.

[0040] The charging interface module of the battery assembly 47 is accurately connected to the charging circuit inside the charging cabinet 41 through a plug-in connector, completing the installation and charging connection of the battery. During the battery charging process, the ventilation slot 5 on the top of the charging cabinet 41 and the cooling radiator 8 at the bottom of the rear end work together to ensure heat dissipation. The ventilation slot 5 forms an air convection channel to accelerate air circulation and dissipate some heat. When the battery generates a lot of heat during charging, the cooling radiator 8 is activated to actively and forcibly cool the heat generated during the battery charging process, ensuring that the battery operates within a suitable temperature range and extending the battery life.
