DETAILED DESCRIPTION

[0027] The technical solutions of the present application will be described clearly and completely below in conjunction with the drawings. Obviously, the described embodiments are part of the embodiments of the present application, not all embodiments. Based on the embodiments in the present application, all other embodiments obtained by those skilled in the art without creative labor are within the scope of protection of the present application.

[0028] The embodiment of the present application discloses a kind of energy storage battery box. Figures 1 to 3 One kind of energy storage battery box includes shell 1, cover plate (not shown in the figure) and at least two battery modules 2 arranged in shell 1, spacer 3 is arranged between adjacent two battery modules 2, installation cavity 11 is opened in the length direction in spacer 3, accommodating cavity 31 is opened in the both ends of shell 1 corresponding installation cavity 11, installation cavity 11 is communicated with accommodating cavity 31, horizontal bar 111 is slidably arranged in accommodating cavity 31, the both ends of horizontal bar 111 are arranged towards the side of battery module 2, and baffle 112 is arranged.

[0029] Sliding slot 12 is opened in shell 1 corresponding baffle 112, and multiple sliding slots 12 and multiple baffles 112 are one-to-one correspondingly arranged, sliding rod 313 is slidably arranged in the both ends of installation cavity 11 along the length direction of spacer 3, and the lower ends of the two sliding rods 313 are extended into accommodating cavity 31 and are fixedly connected with corresponding horizontal bar 111, and adjusting mechanism is arranged on spacer 3 for driving the two sliding rods 313 to slide in accommodating cavity 31 and locking.

[0030] When battery module 2 needs to be disassembled, the cover plate is opened, the two sliding rods 313 are driven to slide in accommodating cavity 31 by adjusting mechanism, and are away from each other, so that the horizontal bar 111 fixedly connected therewith drives baffle 112 to move away from battery module 2, thereby releasing the fixation of battery module 2; when battery module 2 needs to be installed, battery module 2 is placed into shell 1, the two sliding rods 313 are driven to slide in accommodating cavity 31 by adjusting mechanism, and are close to each other, at this time, the horizontal bar 111 fixedly connected therewith drives baffle 112 to move close to battery module 2, until battery module 2 is tightly pressed and locked. The problem that the existing energy storage battery box is relatively cumbersome when disassembling and maintaining the battery module 2 close to the end of life is effectively improved.

[0031] Specifically, referring to Figures 1 to 3 , the adjusting mechanism includes two relatively staggered gear racks 312 and a gear 311 meshingly connected with the two gear racks 312, the gear rack 312 is fixedly arranged on the upper end of the sliding rod 313 in the accommodating cavity 31 along the length direction of the sliding rod 313, and the gear 311 is rotatably arranged on the spacer 3, and the spacer 3 is provided with a locking assembly for locking the gear 311.

[0032] Further, referring to Figures 1 to 3 , the locking assembly includes a straight rod 4, a handle 41 and a locking pin 42, the straight rod 4 is coaxially fixed at one end of the gear 311, the handle 41 is fixedly connected to the straight rod 4, a lock hole (not shown in the figure) is opened on the spacer 3, and the locking pin 42 is arranged on the free end of the handle 41 and is threadedly matched with the lock hole; when the handle 41 is turned to align the locking pin 42 with the lock hole, the baffle 112 extends out of the sliding slot 12 and is tightly pressed against the battery module 2.

[0033] Thus, when the battery module 2 needs to be disassembled, unscrewing the locking pin 42 makes the locking pin 42 disengage from the locking hole, rotating the handle 41 drives the gear 311 to rotate synchronously, the rotation of the gear 311 drives the two racks 312 connected with the gear 311 to slide in the accommodating cavity 31 and move away from each other, the sliding of the racks 312 drives the sliding rods 313 fixedly connected with the racks 312 to slide, the sliding of the sliding rods 313 drives the cross bars 111 fixedly connected with the sliding rods 313 to drive the baffle plates 112 to move away from the battery module 2, thereby releasing the fixation of the battery module 2.

[0034] When the battery module 2 needs to be installed, the battery module 2 is placed in the shell 1, rotating the handle 41 in the reverse direction drives the gear 311 to rotate synchronously, the rotation of the gear 311 drives the two racks 312 connected with the gear 311 to slide in the accommodating cavity 31 and move close to each other, the sliding of the racks 312 drives the sliding rods 313 fixedly connected with the racks 312 to slide, the sliding of the sliding rods 313 drives the cross bars 111 fixedly connected with the sliding rods 313 to drive the baffle plates 112 to move close to the battery module 2 until the battery module 2 is tightly pressed. At this time, the locking pin 42 is aligned with the locking hole, and tightening the locking pin 42 makes the battery module 2 tightly locked with the shell 1. Through the design of the adjusting mechanism and the locking assembly, the quick disassembly and stable locking of the battery module 2 and the shell 1 are realized.

[0035] Moreover, referring to Figure 1 and Figure 4 , the battery module 2 is provided with a guide column 5 at both ends, and the shell 1 is provided with a guide groove 13 corresponding to the guide column 5; when the handle 41 is turned over to align the locking pin 42 with the locking hole, the baffle plate 112 extends out of the sliding groove 12 and tightly presses against the guide column 5.

[0036] The guide column 5 plays a guiding and positioning role, ensuring the correct installation and stable placement of the battery module 2 in the shell 1, and the guide groove 13 is shaped and sized to match the guide column 5, so that the guide column 5 can be smoothly inserted into the guide groove 13 and slide therein; the tightly pressing of the baffle plate 112 against the guide column 5 not only ensures the stable placement of the battery module 2 in the shell 1, but also avoids damage to the battery module 2 caused by the baffle plate 112 under the action of external forces such as vibration or impact. Through the interaction of the guide column 5, the guide groove 13 and the locking assembly with the guide column 5, the stable placement and positioning of the battery module 2 in the shell 1 are realized, and the overall performance and safety of the energy storage battery box are improved.

[0037] Moreover, referring to Figure 1 and Figure 4, the arc-shaped guide column 5 has an inner arc side facing the battery module 2, and the arc-shaped guide column 5 enables the battery module 2 to be more easily aligned with the guide groove 13 during installation, thereby reducing installation difficulty and time; meanwhile, when the battery module 2 is completely inserted into the guide groove 13, the contact area between the guide column 5 and the guide groove 13 is larger, thereby providing better support and stability, which helps to prevent displacement or shaking of the battery module 2 under the action of external forces such as vibration or impact.

[0038] Further, referring to Figure 4 , the guide column 5 is provided with a handle 52, and the handle 52 enables an operator to easily grasp and lift the battery module 2, thereby making installation, movement or disassembly more simple and labor-saving; and the safety risk caused by directly holding or dragging the battery module 2 can be reduced.

[0039] Further, referring to Figure 4 , the guide column 5 is provided with a groove 51, and the groove 51 has a size and shape matched with the handle 52 to ensure that the handle 52 can be smoothly flipped and folded back into the groove 51; the handle 52 is hingedly arranged in the groove 51 of the guide column 5 and does not occupy additional space when not in use, so that the overall layout of the battery module 2 and the energy storage battery box is more compact and efficient.

[0040] Meanwhile, referring to Figure 1 and Figure 2 , the straight rod 4 is fixedly connected at the center of the handle 41, so that an operator can be more easily rotated when flipping the handle 41 driving gear 311; when the baffle 112 is received in the sliding groove 12, the handle 41 is parallel to the partition plate 3, and the parallel design enables an operator to intuitively judge the state of the baffle 112 when observing the position of the handle 41, thereby avoiding the inconvenience of taking out the battery module 2 caused by the protrusion of the handle 41.

[0041] In addition, referring to Figure 1 and Figure 3 , the baffle 112 is provided with a buffer pad 113 at one end facing the guide column 5, and the buffer pad 113 is made of rubber, plastic or other materials with high elasticity and wear resistance, thereby reducing the sliding or shaking of the baffle 112 relative to the guide column 5 during vibration or transportation, and further enhancing the stability of the battery module 2 in the housing 1.

[0042] The embodiment of the present application discloses an energy storage system based on the above-mentioned energy storage battery box, referring to Figures 1 to 4 , the energy storage system comprises the above-mentioned energy storage battery box.

[0045] When the battery module 2 needs to be installed, the battery module 2 is placed in the shell 1, the handle 41 is reversely rotated to drive the gear 311 to rotate synchronously, the gear 311 rotates to drive the two racks 312 connected with the gear 311 to slide in the accommodating cavity 31 and move close to each other, the sliding of the racks 312 drives the sliding rods 313 connected with the racks 312 to slide, the sliding of the sliding rods 313 drives the cross rods 111 connected with the sliding rods 313 to move the baffle 112 close to the battery module 2 until the battery module 2 is tightly pressed. At this time, the locking pin 42 is aligned with the locking hole, the locking pin 42 is tightened to lock the battery module 2 and the shell 1. Through the design of the adjusting mechanism and the locking assembly, the quick disassembly and stable locking of the battery module 2 and the shell 1 are realized. The problem that the existing energy storage battery box is relatively cumbersome when disassembling and maintaining the battery module 2 close to the end of life is effectively improved.
