[0032] The following is a further description of the specific implementation of the present invention in conjunction with the accompanying drawings and embodiments. The following embodiments are only used to more clearly illustrate the technical solution of the present invention, and cannot be used to limit the protection scope of the present invention.

[0033] like Figure 1-Figure 12 As shown, the utility model is a new energy battery box energy storage device that is easy to access, including:

[0034] The energy storage cabinet 1 includes a cabinet body 11, a cabinet door 12 and a locking member 13. The cabinet body 11 is open on at least one side. The cabinet door 12 rotates on the open side of the cabinet body 11 and the rotation axis extends along the vertical direction. The locking member 13 is used to lock the cabinet door 12 on the cabinet body 11. In the locked state, the cabinet door 12 closes the open side of the cabinet body 11.

[0035] The storage component includes storage units distributed along the vertical direction, the storage unit includes a storage rack 2 and a connecting component 3, the connecting component 3 is arranged in the cabinet 11, the storage rack 2 moves between the storage station and the picking and placing station through the connecting component 3, the storage rack 2 of the storage station is horizontally arranged in the cabinet 11, and the storage rack 2 of the picking and placing station is inclined downward and the two ends are respectively arranged in the cabinet 11 and outside the cabinet 11.

[0036] In the present invention, the cabinet body 11 is a rectangular parallelepiped structure, wherein both sides facing each other are open, and both sides of the open side are provided with a rotating seat 112, the cabinet door 12 is rotatably connected to the cabinet body 11 through the rotating seat 112, and the rotation axis extends along the vertical direction, and the two cabinet doors 12 on the same open side are locked on the cabinet body 11 through a locking member 13 to close the open side of the cabinet body 11. Specifically, the front of the cabinet door 12 is provided with a lock sleeve 121 extending along the vertical direction, and the locking member 13 includes a connecting rod 132 and a locking pin 131 fixed to both ends of the connecting rod 132. When the two cabinet doors 12 close the open side of the cabinet body 11, the two locking pins 131 are simultaneously inserted into the lock sleeve 121 of the cabinet body 11, so that the cabinet door 12 can be locked. Figure 2 shown.

[0037] The cabinet door 12 is provided with a vent, and a shutter 122 is installed inside the vent to meet the ventilation and heat dissipation needs of the energy storage cabinet 1.

[0038] A base 14 is fixedly provided below the cabinet body 11. The base 14 is used to support the cabinet body 11. The projection of the base 14 on the horizontal plane coincides with the projection of the cabinet body 11 on the horizontal plane to achieve good support. Sockets 141 are provided on the four sides of the circumferential outer edge of the base 14. The sockets 141 are through-hole-shaped for forklifts to insert, so that it is convenient for the forklift to insert the base 14 from any side to carry the energy storage cabinet 1.

[0039] A plurality of support plates 111 extending in the vertical direction are fixed in the cabinet body 11, and the two ends of the support plates 111 extend to the inner top wall and the inner bottom wall of the cabinet body 11 respectively. The inner cavity of the cabinet body 11 is divided into four storage cavities distributed in a rectangular array by the plurality of support plates 111. Storage components are arranged in the four storage cavities. The storage components include a plurality of storage racks 2 and a connecting component 3 distributed in the vertical direction. The connecting component 3 facilitates the movement of the storage rack 2, and the position of the storage rack 2 is adjusted so that the activity path of the storage rack 2 includes a storage station and a pick-and-place station.

[0040] At the pick-and-place station, one end of the storage rack 2 is located in the cabinet 11, and the other end extends out of the cabinet 11, and at the pick-and-place station, the storage rack 2 is tilted downward. After adopting the above design, it is not only convenient for the operating worker to observe the pick-and-place position of the battery box, so that if the storage rack 2 is located at a low place, the pick-and-place operation can be performed directly on the storage rack 2, and if the storage rack 2 is in a high position, due to the tilted setting of the storage rack 2, the pick-and-place height requirement of the battery box is reduced, making it more convenient and safe to pick and place the battery box on the high storage rack 2; and at the storage station, the storage rack 2 is horizontally set in the cabinet 11, and the battery box can be safely stored using the storage rack 2.

[0041] Therefore, when storing the battery box, the storage rack 2 can be adjusted to the pick-and-place position so that it is partially exposed outside the cabinet 11 and tilted, thereby lowering the placement height requirement and making it easier to observe the position of the storage rack 2. After the battery box is placed on the storage rack 2, the storage rack 2 is adjusted to the storage position to complete the storage operation of the battery box. When taking the battery box, the storage rack 2 originally at the storage position is also adjusted to the pick-and-place position to complete the removal operation of the battery box from the storage rack 2.

[0042] A further improvement is that the connecting component 3 includes a guide rail 31, a rolling member 32, a storage support member 33 and a pick-and-place support member 34, the rolling member 32 rollingly cooperates with the guide rail 31, the guide rail 31 extends in a horizontal direction perpendicular to the open side of the cabinet 11 and is fixed in the cabinet 11, the rolling member 32 is rotatably connected to the storage rack 2 and extends in a horizontal direction perpendicular to the guide rail 31 relative to the rotation axis, the storage support member 33 and the pick-and-place support member 34 are respectively used to support the storage rack 2 of the storage station and the storage rack 2 supporting the pick-and-place station.

[0043] After the connecting component 3 adopts the above structure, the rolling direction of the rolling member 32 is guided by the guide rail 31, and the storage support member 33 and the pick-and-place support member 34 are used to support the storage rack 2 of the storage station and the storage rack 2 of the pick-and-place station respectively, ensuring that at the storage station, the storage rack 2 is horizontally arranged in the cabinet 11 to support the battery box, and at the pick-and-place station, the storage rack 2 can be tilted downward to reduce the pick-and-place height requirement, making the battery box pick-and-place more convenient and labor-saving.

[0044] A further improvement is that the storage support 33 is a support groove with an open top, which is arranged at one end of the guide rail 31 adjacent to the open side of the cabinet 11 and extends in a horizontal direction perpendicular to the length direction of the guide rail 31, and the storage rack 2 includes a convex shaft 211 whose extension direction is consistent with the length direction of the support groove, and the support groove is used to support the convex shaft 211; the pick-up and placement support 34 includes a support sleeve 342 arranged between the guide rail 31 and the open side of the cabinet 11, the axial direction of the support sleeve 342 is horizontal and perpendicular to the length direction of the guide rail 31, and the support sleeve 342 rotates on the cabinet 11 around its own axis; two guide rails 31 are provided, which are arranged on both sides of the storage rack 2.

[0045] Specifically, Figure 4-Figure 10 As shown, the guide rails 31 of the connecting components 3 on both sides of the storage rack 2 are C-shaped in cross-section and are arranged opposite the storage rack 2, wherein one guide rail 31 is fixed on the inner wall of the cabinet 11, and the other guide rail 31 is fixed on the support plate 111; the position of the storage rack 2 is conveniently adjusted by rolling the rolling member 32 on the guide rail 31, and the rolling member 32 can support one end of the storage rack 2, while the other end of the storage rack 2 is supported by the storage support member 33 and the pick-and-place support member 34, so that the storage rack 2 is located at the storage station or the pick-and-place station.

[0046] The storage support member 33 is a support groove with the top facing upward, one of which is formed on one side of the guide rail 31 close to the open side of the cabinet 11. A cam 211 is provided on the storage rack 2. The cam 211 is placed in the support groove, and the bottom of the support groove is used to support the cam 211. The inner side wall of the support groove is used to prevent the cam 211 from detaching from the support groove, thereby achieving stable support for the storage station storage rack 2.

[0047] The pick-and-place support member 34 includes a fixed shaft 341 and a support sleeve 342, wherein both ends of the fixed shaft 341 are fixedly connected to the inner walls of both sides of the cabinet body 11, and the support sleeve 342 is sealed and arranged outside the fixed shaft 341, and can rotate around its own axis, and the storage rack 2 above it is supported by the support sleeve 342, and the support sleeve 342 is located at the lower side of the guide rail 31, so that when the storage rack 2 is pulled out of the cabinet body 11, the storage rack 2 is first lifted upward to disengage the convex shaft 211 After the support groove is pulled outward for a short distance, the convex shaft 211 moves to the upper side of the support groove, and then the storage rack 2 can be lowered. The storage rack 2 is supported by the support sleeve 342, and the rolling element 32 rolls on the guide rail 31. The support sleeve 342 rotates around its own axis, which makes it convenient for the storage rack 2 to tilt downward and extend outward from the cabinet body 11 until the rolling element 32 rolls to the end of the guide rail 31 adjacent to the fixed shaft 341, thereby adjusting the storage rack 2 to the pick-up and placement position.

[0048] A further improvement is that the storage rack 2 includes support shafts 23 distributed side by side, the axial direction of the support shaft 23 is horizontal and perpendicular to the length direction of the guide rail 31, the support shaft 23 is rotatably arranged around its own axis, and the support shaft 23 is used to support the battery box.

[0049] The specific structure of the storage rack 2 is as follows: Figure 9-12 As shown, the storage rack 2 includes a rack body 21, which is a rectangular frame structure. The length direction of the rack body 21 is consistent with the width direction of the cabinet body 11. One end of the rack body 21 that is always inside the cabinet body 11 is penetrated by a roller 22 extending along the length direction of the cabinet body 11. The rolling member 32 is a rolling bearing. The inner ring of the rolling bearing is fixedly connected to the roller 22, and the outer ring rolls on the guide rail 31. The rolling bearing rolls on the guide rail 31 to facilitate the adjustment of the position of the rack body 21. The sealing sleeve of the rack body 21 is arranged outside the roller 22, so that the storage rack 2 can rotate relative to the rolling bearing. In the storage position, the storage rack 2 is rotated upward and disengaged from the support groove. After disengaging from the support groove, the storage rack 2 can also rotate downward until the rack body 21 contacts the support sleeve 342. At this time, the rack body 21 tilts downward. When the rolling bearing rolls to the end of the guide rail 31, the storage rack 2 is in the pick-and-place position, which is convenient for taking and placing the battery box on the rack body 21.

[0050] The inner side of the frame 21 is fixed with a transverse axis 24 which is arranged side by side along the length direction thereof and whose axis is parallel to the length direction of the cabinet 11. The support shaft 23 is sealed outside the transverse axis 24 and is coaxial with the transverse axis 24, so that the support shaft 23 can be easily rotated around its own axis. After adopting the above structure, the support shaft 23 can be used to support the battery box. When taking and placing, the battery box moves along the length direction of the frame 21, so that the support shaft 23 rotates, thereby avoiding sliding friction and reducing the wear on the bottom of the battery box. At the same time, through rolling friction, the friction force of the battery box when being pushed and pulled is reduced, thereby facilitating the movement of the battery box and further facilitating the taking and placing operation.

[0051] A further improvement is that the storage rack 2 also includes limit members arranged around the four sides of the support shaft 23; the limit members include movable limit members 4, and when the storage rack 2 is located at the pick-up and placement station, the movable limit members 4 are located outside the cabinet 11 and lower than the limit members on the other three sides; the movable limit member 4 is connected to an elastic member 42, and the elastic member 42 is used to make the limit member have a tendency to move upward along the thickness direction of the storage rack 2; a limiting sleeve 41 is arranged on the movable limit member 4, and the limiting sleeve 41 extends in a horizontal direction perpendicular to the length direction of the guide rail 31 and is arranged to rotate around its own axis.

[0052] like Figure 8-Figure 12 As shown, limiting members are provided on the four sides of the frame 21 for surrounding and limiting the battery boxes stored on the frame 21 to prevent the battery boxes from falling and ensure the safe storage of the battery boxes.

[0053] The limiting members on the four sides are respectively located at the movable limiting members 4 and the fixed limiting members 5. Specifically, the fixed limiting members 5 are fixedly arranged on three sides above the frame body 21, and the limiting member on the other side is the movable limiting member 4. When the storage rack 2 is located at the pick-up and placement station, the movable limiting member 4 is lower than the height position of the fixed limiting members 5 on the other three sides.

[0054] A step hole 213 is provided at one end of the frame 21 away from the roller 22. The step hole 213 is a through hole. The end with a smaller opening of the step hole 213 is located on the top surface of the frame 21, and the end with a larger opening is located on the bottom surface of the frame 21. The movable limit member 4 is provided with a limit sleeve 41 whose axial direction is parallel to the length direction of the cabinet 11. The limit sleeve 41 is rotated around its own axis and is arranged above the frame 21. The movable limit member 4 is also connected to a slide rod that slides through the step hole 213. The bottom end of the slide rod is fixedly connected with a push-pull plate 43, and the elastic member 42 is a tension spring, one end of the tension spring is connected to the push-pull plate 43, and the other end is arranged at the lower part of the step hole 213; a protrusion 214 is also arranged at the bottom of the frame body 21, and the protrusion 214 is used to limit the movable path of the push-pull plate 43 to prevent the push-pull plate 43 from fitting with the bottom surface of the frame body 21; a notch 212 is also arranged on the top surface of the frame body 21, and the notch 212 is opposite to the movable limit member 4 for accommodating the movable limit member 4.

[0055] Due to the action of the tension spring, the push-pull plate 43 moves upward, close to the frame 21 and against the protrusion 214, and the movable limit member 4 moves upward through the slide rod to increase the height of the limit sleeve 41, thereby effectively preventing the battery box above the frame 21 and between the four limit members from falling from the four sides of the frame 21; when the battery box needs to be taken out, the push-pull plate 43 is pulled downward, and the movable limit member 4 moves downward to the recess 212 through the slide rod, thereby lowering the height of the limit sleeve 41, making it convenient for the battery box to pass through the limit sleeve 41, thereby removing the battery box. When the storage rack 2 is unloaded and a battery box needs to be placed on the storage rack 2, the battery box can be directly pressed on the limit sleeve 41, so that the slide bar drops, the tension spring is stretched, the movable limit member 4 moves down, and then the battery box is pushed along the length direction of the rack body 21 until the battery box passes through the limit sleeve 41. The limit sleeve 41 is no longer under pressure, and under the elastic force of the elastic member 42, the movable limit member 4 and the limit sleeve 41 are pushed upward, so that after the height of the limit sleeve 41 is increased, it can prevent the battery box from falling, thereby ensuring stable and safe storage of the battery box.

[0056] The above is only a preferred embodiment of the present invention. It should be pointed out that for ordinary technicians in this technical field, several improvements and modifications can be made without departing from the technical principle of the present invention. These improvements and modifications should also be regarded as the protection scope of the present invention.
