Description

Technical Field

[0001] This utility model relates to the field of lithium battery energy storage cabinet technology, and in particular to an energy storage cabinet structure that can synchronously adjust the spacing between adjacent partitions. Background Technology

[0002] A lithium battery energy storage cabinet is a cabinet that stores electrical energy using lithium batteries. Its general structure is as follows: it is cabinet-shaped, with a box at the bottom and a placement board at the top. The lithium batteries are placed on the placement board, and the inverter, management module, etc. are placed in the box at the bottom, which separates the lithium batteries from the inverter, management module, etc., reducing safety hazards.

[0003] Because lithium battery storage cabinets typically hold multiple lithium battery packs on a shelf, if one battery catches fire, it can cause other batteries to catch fire, creating a safety hazard. Therefore, many companies now choose to install multiple shelf units – that is, multiple partitions, each holding one lithium battery – so that if one battery catches fire, it will not affect the others.

[0004] Because lithium batteries from different manufacturers have varying heights, lithium battery storage cabinets need to be designed and manufactured with adjustable partitions to accommodate batteries of different heights. However, current partition adjustment methods are based on wardrobe design, making each partition detachable. When needed, the partitions can be removed and reinstalled, which allows for adjustment of the spacing between partitions, but it is still not convenient enough.

[0005] Considering that the height of each lithium battery in a lithium battery energy storage cabinet is the same, is there an adjustment method that can synchronously change the spacing between adjacent partitions with a single adjustment? To achieve this, the inventors designed this solution. Utility Model Content

[0006] The purpose of this utility model is to provide an energy storage cabinet structure that can synchronously adjust the spacing between adjacent partitions, thereby solving the problem that the adjustment of each partition in the existing energy storage cabinet is relatively inconvenient. This solution can make each partition move synchronously through simple adjustment, and make the spacing between each adjacent partition change in a consistent manner.

[0007] To achieve the above objectives, the present invention adopts the following technical solution:

[0008] An energy storage cabinet structure capable of synchronously adjusting the spacing between adjacent partitions includes a cabinet body, a box body at the bottom of the cabinet body, and multiple partitions spaced at the top of the cabinet body.

[0009] The partition can be slidably installed between the left and right walls of the cabinet.

[0010] An auxiliary strip is fixed to the rear wall of the partition, and a spacing adjustment component I is provided on the rear wall of the cabinet. The spacing adjustment component I has multiple discs with annular grooves on them, and an adaptive arc-shaped protrusion is provided on the auxiliary strip, with the arc-shaped protrusion embedded in the annular groove.

[0011] The spacing adjustment component I moves the disc up and down, and keeps the spacing between adjacent discs consistent during the movement, thus allowing the equal spacing between adjacent partitions to be adjusted synchronously.

[0012] As a preferred technical solution of this application, the spacing adjustment component I is formed by connecting multiple unit sections II. Each unit section II includes a first connecting rod and a second connecting rod. Both the first and second connecting rods have a collar at their middle portions. The collar of the second connecting rod is fitted onto a sleeve via a keyway structure. The sleeve of the first connecting rod is fitted onto a rotating shaft via a keyway structure. The rotating shaft passes through the sleeve and extends out of the sleeve at both ends. A disc is fixed to the inner end of the rotating shaft. A rotation locking mechanism III is provided between the rotating shaft and the sleeve. The first and second connecting rods in unit section II form a cross shape. Between adjacent unit sections II, the upper end of the first connecting rod of the lower unit section II is hinged to the lower end of the second connecting rod of the upper unit section II via a revolute joint, and the upper end of the second connecting rod of the lower unit section II is hinged to the upper end of the first connecting rod of the upper unit section II via a revolute joint; thus, multiple unit sections II are connected to form the spacing adjustment component I.

[0013] As a preferred technical solution of this application, the rotating locking mechanism III includes a cap and a gear disc. The cap is sleeved and fixed to the outer end of the rotating shaft, and has a protrusion on the cap. A lever is hinged to the protrusion in a rotating pair. The gear disc is fixed to the sleeve. A hand lever is also provided on the cap. The cap rotates the rotating shaft by the hand lever, and the rotating shaft drives the disc and the first connecting rod to rotate. When the first connecting rod rotates, the angle between the first connecting rod and the second connecting rod will inevitably increase / decrease. When the angle between the first connecting rod and the second connecting rod of a certain unit section II increases / decreases, it will inevitably cause the first connecting rod and the second connecting rod of other unit sections II to synchronously increase / decrease in the same angle. Therefore, the spacing change between the discs on adjacent unit sections II on the spacing adjustment component I is always consistent. In addition, when the rotating shaft drives the disc to rotate, the arc-shaped protrusion on the auxiliary strip rotates relative to the annular groove of the disc.

[0014] As a preferred technical solution of this application, the outer ends of the sleeve and the rotating shaft extend out of the cabinet body through the through groove in the vertical direction of the rear wall of the cabinet.

[0015] As a preferred technical solution of this application, in the spacing adjustment component I: in the unit section II located at the uppermost position, the upper end of the first connecting rod is hinged to the lower end of the second upper auxiliary rod, the upper end of the second connecting rod is hinged to the lower end of the first upper auxiliary rod, and the upper ends of the first upper auxiliary rod and the upper ends of the second upper auxiliary rod are hinged through an upper pin. The outer end of the upper pin is hinged to a slider, and the slider is fitted and slidably mates with the through groove on the rear wall of the cabinet.

[0016] As a preferred technical solution of this application, in the spacing adjustment component I, in the lowermost unit section II:

[0017] It includes a first connecting rod and a second connecting rod. Both the first connecting rod and the second connecting rod have a collar at the middle. The collar of the second connecting rod is sleeved on the sleeve via a keyway structure. The sleeve of the first connecting rod is sleeved on the rotating shaft via a keyway structure. The rotating shaft passes through the sleeve and extends out of the sleeve at both ends.

[0018] A disc is fixed to the inner end of the rotating shaft;

[0019] A handwheel is fixed to the outer end of the rotating shaft, a ratchet is fitted to the outer end of the sleeve, and a pawl is fixed to the outer side of the rear wall of the cabinet. The pawl is adapted to the ratchet.

[0020] The sleeve is placed at the bottom of the through groove on the rear wall of the cabinet;

[0021] When the rotation locking mechanism III in other unit sections II is opened, turning the handwheel in the bottommost unit section II will cause the first connecting rod in that unit section II to rotate, thereby causing the second connecting rod in the bottommost unit section II to rotate. At the same time, it will also cause the corresponding two rods in other unit sections II to rotate, thereby adjusting the position of each disc in each adjacent unit section II.

[0022] As a preferred technical solution of this application, the cabinet has corresponding sliding grooves on the left and right inner walls along the vertical direction, and tenon heads are provided on the left and right edges of the partition, with the tenon heads cooperating with the sliding grooves.

[0023] Compared with the prior art, the beneficial effects of this utility model are as follows:

[0024] By turning the handwheel, the distance between adjacent partitions can be adjusted synchronously to increase or decrease, and the change in distance between each partition is consistent, making it very convenient to adjust the distance between adjacent partitions.

[0025] In addition, the rotating locking mechanism III can further ensure the proper locking of the entire pitch adjustment assembly I. Attached Figure Description

These terms are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation, and therefore should not be construed as a limitation on this utility model. In addition, the terms "first," "second," etc., are only used to distinguish descriptions and should not be construed as indicating or implying relative importance.

[0042] like Figure 1 Figure 5 As shown, this embodiment proposes an energy storage cabinet structure capable of synchronously adjusting the spacing between adjacent partitions, including a cabinet body, a box 1 at the bottom of the cabinet body, and multiple partitions 2 spaced apart at the top of the cabinet body.

[0043] The cabinet has corresponding sliding grooves on the left and right inner walls along the vertical direction, and tenon heads 201 are provided on the left and right edges of the partition 2. The tenon heads cooperate with the sliding grooves 6, allowing the partition 2 to slide vertically between the left and right walls of the cabinet.

[0044] Among them, an auxiliary strip 202 is fixed on the rear wall of the partition 2, and a spacing adjustment component I is provided on the rear wall of the cabinet; the spacing adjustment component I has multiple discs 1601, annular grooves are opened on the discs 1601, and matching arc-shaped protrusions are opened on the auxiliary strip 202, with the arc-shaped protrusions embedded in the annular grooves.

[0045] During operation, the spacing adjustment component I moves the disk 1601 up and down, and keeps the spacing between adjacent disks 1601 consistent during the movement, thus allowing the adjacent partitions 2 to adjust synchronously at equal intervals.

[0046] The following is a further explanation of the spacing adjustment component I.

[0047] The spacing adjustment component I is formed by connecting multiple unit sections II.

[0048] Specifically, see Figure 3 and Figure 4 Unit section II includes a first connecting rod 7 and a second connecting rod 8. Both the first connecting rod 7 and the second connecting rod 8 have a collar at the middle. The collar of the second connecting rod 8 is sleeved on the sleeve 17 via a keyway structure. The sleeve of the first connecting rod 7 is sleeved on the rotating shaft 16 via a keyway structure. The rotating shaft 16 passes through the sleeve 17 and extends out of the sleeve 17 at both ends.

[0049] A disc 1601 is fixed at the inner end of the rotating shaft 16;

[0050] A rotation locking mechanism Ⅲ is provided between the rotating shaft 16 and the sleeve 17;

[0051] In unit section II, the first link 7 and the second link 8 form a cross shape.

[0052] During installation: between adjacent unit sections II, the upper end of the first connecting rod 7 of the lower unit section II is hinged to the lower end of the second connecting rod 8 of the upper unit section II as a rotating joint, and the upper end of the second connecting rod 8 of the lower unit section II is hinged to the upper end of the first connecting rod 7 of the upper unit section II as a rotating joint; in this way, multiple unit sections II are connected to form a spacing adjustment assembly I.

[0053] Furthermore, the preferred embodiment of the rotary locking mechanism III is described.

[0054] See Figure 4 The rotating locking mechanism III includes a cap 1602 and a gear plate 1701. The cap 1602 is sleeved and fixed to the outer end of the rotating shaft 16, and has a protrusion on the cap 1602. A lever 1604 is hinged to the protrusion in a rotating pair. The gear plate 1701 is fixed to the sleeve 17. In addition, a hand lever 1603 is also provided on the cap 1602.

[0055] During operation: The hand lever 1603 causes the cap 1602 to rotate, which in turn rotates the shaft 16. The shaft 16 then rotates the disc 1601 and the first connecting rod 7. When the first connecting rod 7 rotates, the angle between it and the second connecting rod 8 inevitably increases or decreases. When the angle between the first connecting rod 7 and the second connecting rod 8 of a certain unit section II increases or decreases, it will inevitably cause the angle between the first connecting rod 7 and the second connecting rod 8 of other unit sections II to increase or decrease synchronously. Therefore, the spacing between the discs 1601 on adjacent unit sections II on the spacing adjustment assembly I remains consistent. Furthermore, when the shaft 16 rotates the disc 1601, the arc-shaped protrusion on the auxiliary strip 202 rotates relative to the annular groove of the disc 1601.

[0056] Furthermore, the upper part of the spacing adjustment component I will now be designed.

[0057] It should be noted that the outer ends of the sleeve 17 and the pivot 16 in the vertical direction of the rear wall of the cabinet all extend out of the cabinet body through the through groove 11.

[0058] See Figure 3 and Figure 4 In the spacing adjustment assembly I: in the unit section II located at the top, the upper end of the first connecting rod 7 is hinged to the lower end of the second upper auxiliary rod, the upper end of the second connecting rod 8 is hinged to the lower end of the first upper auxiliary rod, and the upper ends of the first upper auxiliary rod and the upper ends of the second upper auxiliary rod are hinged by an upper pin. The outer end of the upper pin is hinged to a slider 15, and the slider 15 is fitted and slids with the through groove 11 on the rear wall of the cabinet.

[0059] Furthermore, the design of the lower end of the spacing adjustment component I is described below.

[0060] See Figure 6 In the spacing adjustment component I, in the bottommost unit section II:

[0061] It also includes the first connecting rod 7 and the second connecting rod 8. Both the first connecting rod 7 and the second connecting rod 8 have a collar at the middle. The collar of the second connecting rod 8 is sleeved on the sleeve 17 via a keyway structure. The sleeve of the first connecting rod 7 is sleeved on the rotating shaft 16 via a keyway structure. The rotating shaft 16 passes through the sleeve 17 and extends out of the sleeve 17 at both ends.

[0062] A disc 1601 is fixed to the inner end of the rotating shaft 16;

[0063] Unlike other unit sections II, in the unit section II located at the bottom: a handwheel 12 is fixed to the outer end of the rotating shaft 16, a ratchet 18 is fitted to the outer end of the sleeve 17, and a pawl 19 is fixed to the outer side of the rear wall of the cabinet. The pawl 19 is adapted to the ratchet 18.

[0064] In addition, the sleeve 17 is placed at the bottom of the through groove 11 on the rear wall of the cabinet;

[0065] During operation, when the rotation locking mechanism III in other unit sections II is opened, rotating the handwheel 12 in the bottommost unit section II will cause the first connecting rod 7 in that unit section II to rotate, thereby causing the second connecting rod 8 in the bottommost unit section II to rotate. At the same time, it will also cause the corresponding two rods in other unit sections II to rotate, thereby realizing the adjustment of the position of each disc 1601 in each adjacent unit section II.

[0066] In this embodiment, the pawl 19 is fixed to the rear side wall of the solid by a positioning pin, and a torsion spring is provided between the pawl 19 and the positioning pin. A hand lever 1901 is also provided on the pawl 19.

[0067] To facilitate understanding, the entire working process of this solution will be explained.

[0068] I. Reference Figure 4 Release the rotation locking mechanism III of unit section II except for the bottom unit section II, that is, rotate the actuating member 1604 so that the actuating member 1604 is not stuck on the gear plate 1701.

[0069] II. Reference Figure 6Then, turn the handwheel 12 clockwise. The handwheel 12 will cause the first connecting rod 7 in the bottom unit section II to rotate clockwise (the upper end of the first connecting rod 7 moves closer to the vertical center line of the spacing adjustment component I). According to the structure of the spacing adjustment component I, when the first connecting rod 7 in the bottom unit section II rotates clockwise, the second connecting rod 8 in the bottom unit section II will inevitably rotate counterclockwise (the upper end of the second connecting rod 8 also moves closer to the vertical center line of the spacing adjustment component I). Therefore, in the bottom unit section II, the included angle between the upper ends of the first connecting rod 7 and the second connecting rod 8 becomes smaller.

[0070] When the upper ends of the first link 7 and the second link 8 of the bottom unit section II are brought together, the upper ends of the first link 7 and the second link 8 of the adjacent upper unit section II will inevitably be brought together. In this way, the upper ends of the first link 7 and the second link 8 of all unit sections II can be brought together, and the entire spacing adjustment component I is in an extended state.

[0071] When the entire spacing adjustment assembly I is in an elongated state, the disks 1601 in each unit section II will lift the partitions upward via the auxiliary strips 202, thereby increasing the spacing between each partition 2 synchronously.

[0072] Then, release handwheel 12, and under the action of pawl 19, lock ratchet 18. As a result, the lowest unit section II is locked, and the included angle between the first link 7 and the second link 8 in this unit section no longer changes; the included angle between the first link 7 and the second link 8 in other unit sections II also no longer changes.

[0073] Then rotate the actuating element 1604 until it is locked at the gear plate 1701, further locking each unit section II.

[0074] Third, when the toggle bar 1901 is pressed manually, the pawl 19 and ratchet 18 are released, so the handwheel can be rotated counterclockwise, thus enabling the spacing between each partition 2 to decrease synchronously.

[0075] 4. When the adjacent partitions 2 are adjusted to a suitable spacing, place lithium batteries on each partition 2.

[0076] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
