Description

Technical Field

[0001] The present invention belongs to the technical field of liquid-cooled energy storage cabinets, and specifically relates to a high-density liquid-cooled energy storage cabinet. Background Art

[0002] A liquid-cooled energy storage cabinet is an energy storage device that uses liquid cooling technology to manage the temperature of batteries. This device generally includes components such as a battery pack, a battery management system (BMS), an inverter, and a control system, and can achieve the storage and release of electrical energy. Among them, the battery pack is generally installed in the cabinet body through fixed or sliding brackets, and the battery packs are fixed to the brackets by bolts. When disassembling, it is necessary to first remove the brackets from the cabinet body, and then remove the battery packs from the brackets. These two steps of disassembly are relatively troublesome. At the same time, when moving the battery packs, due to the large weight of the battery packs, the inertia generated is relatively large. For sliding brackets, when pulling the brackets, it is easy to impact the ends of the sliding rails on both sides, which is likely to cause deformation of the two ends of the guide rails over time. And because the battery packs in the liquid-cooled energy storage cabinet are arranged very close to each other, it is difficult to directly align and install after disassembling and overhauling a single battery pack in the middle area. Therefore, a high-density liquid-cooled energy storage cabinet is proposed for the above problems. Summary of the Invention

[0003] To solve the problem that the battery packs are installed on the brackets, and the brackets are then fixed in the cabinet body, which requires two steps for both disassembly and installation and is relatively troublesome as mentioned in the above background art, the present invention provides a high-density liquid-cooled energy storage cabinet.

[0004] To achieve the above object, the present invention provides the following technical solution: A high-density liquid-cooled energy storage cabinet, including a liquid-cooled energy storage cabinet body, and further including,

[0005] A bracket seat, which is installed inside the liquid-cooled energy storage cabinet body;

[0006] Connecting columns, which are symmetrically rotated at both ends inside the bracket seat;

[0007] A sliding mechanism, which is arranged on the surface of the connecting columns. The sliding mechanism includes a first sliding component, a second sliding component, and a connecting spring. The first sliding component is slidably connected to the second sliding component, and both ends of the connecting spring are respectively connected to the first sliding component and the second sliding component;

[0008] A transmission mechanism, which is arranged at one end of the connecting column and is used to drive the connecting column to rotate;

[0009] A second bracket and a third bracket, which are arranged vertically and both slide inside the bracket seat. The third bracket is used to drive the transmission mechanism to move;

[0010] A first bracket, which is rotatably connected to the top of the second bracket;

[0011] The fixing plate is arranged on the second bracket and extends into the first bracket.

[0012] Preferably, a thread strip is provided on the surface of the connecting column, the pitch of one end of the thread strip is larger than that of the other end, and the connecting spring is sleeved on the surface of the connecting column and matched with the pitch of the thread strip on the surface of the connecting column.

[0013] Preferably, the second sliding assembly comprises a second sliding seat and an extrusion block, the second sliding seat is connected to the extrusion block via a first connecting block, and the first sliding assembly is connected to the second bracket via a second connecting block.

[0014] Preferably, the second bracket includes a bracket plate, a fixed shaft and a sliding groove, the bracket plate is connected to the first sliding assembly through a second connecting block, the fixed shaft is fixedly installed at one end of the bracket plate, the sliding groove is symmetrically opened on the surface of the bracket plate, and the extrusion block is slidably arranged inside the sliding groove.

[0015] Preferably, a protrusion located inside the sliding groove is further provided at the bottom of the first bracket, and one end of the protrusion close to the extrusion block is inclined.

[0016] Preferably, the fixing plate is threadedly connected to the surface of the fixing shaft, and there are two fixing plates which are symmetrically arranged at both ends of the fixing shaft.

[0017] Preferably, the first bracket is hinged to the fixed shaft, the fixed plate is slidably connected to the first bracket along the axial direction of the fixed shaft, and the extrusion block can drive the first bracket to rotate around the fixed shaft as the center axis by moving and extruding the protrusion at the bottom of the first bracket.

[0018] Preferably, the transmission mechanism includes a synchronization component, a first bevel gear, a mating component and a tooth plate, the first bevel gear is transmission-connected to the connecting column through the synchronization component, the first bevel gear is meshed with the mating component, the mating component is meshed with the tooth plate, and the tooth plate is mounted on the side of the third bracket.

[0019] Preferably, the mating component includes a second bevel gear and a gear, the second bevel gear is fixedly connected to the gear, the second bevel gear is meshed with the first bevel gear, the gear is meshed with the toothed plate, and the mating component is rotatably connected to the inside of the bracket seat.

[0020] Preferably, when the connecting column rotates, it can drive the first sliding component, the second sliding component and the connecting spring to move inside the bracket seat along the axial direction of the connecting column. When the connecting spring is located at the end with a shorter pitch of the thread strip on the surface of the connecting column, it is in a compressed state, and at this time, the second sliding component moves toward the inside of the first sliding component.

[0021] Compared with the prior art, the present invention has the following beneficial effects:

[0022] 1. The present invention can drive the connecting column to rotate through the transmission mechanism by pulling the third bracket outward, thereby driving the sliding mechanism to move. When the sliding mechanism moves, it can drive the second bracket and the first bracket to move synchronously, so that the first bracket, the second bracket, the third bracket and the battery pack are removed from the bracket seat. Moreover, since the pitches of the threads at both ends of the connecting column surface are different, when the sliding mechanism is located at the end with a shorter pitch of the threads on the connecting column surface, the speed of the first bracket and the second bracket moving out is slowed down, thereby having a warning effect. At this time, relative sliding occurs between the second bracket and the third bracket, which increases the resistance to movement, thereby reducing inertia, and preventing the inertia of the battery pack movement from damaging the two ends of the slide rail.

[0023] 2. In the present invention, when the second sliding seat moves to the end of the connecting column surface with a shorter pitch of the threaded strip, it can move toward the inside of the first sliding assembly, so that the extrusion block can slide on the surface of the second bracket, and the extrusion block can squeeze the first bracket to flip it upward when moving, so that the battery pack is driven by the first bracket to flip upward when it is about to move out of the bracket seat. At this time, when the battery pack is pulled out, the battery pack initially has an inclination angle, thereby reducing the amplitude of the swing required after the battery pack is detached from the first bracket, thereby reducing inertia and reducing the risk of damage caused by the battery pack falling.

[0024] 3. The present invention enables the fixed plate to move on the fixed axis through the rotation of the first bracket, and the battery pack is placed on the first bracket. When the first bracket is flipped upward with the fixed axis as the axis, the two fixed plates move away from each other, that is, the fixation of the battery pack is released, and when the first bracket is flipped downward with the fixed axis as the axis to return to being parallel, the two fixed plates move towards each other, that is, the fixed plate fixes the battery pack through pressure, thereby achieving an automatic fixation effect.

Specific embodiments

[0035] Next, the technical solutions in the embodiments of the present invention will be clearly and completely described in conjunction with the accompanying drawings in the embodiments of the present invention. Obviously, the described embodiments are only a part of the embodiments of the present invention, rather than all the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those of ordinary skill in the art without creative efforts shall fall within the protection scope of the present invention.

[0036] Such as Figures 1 to 9As shown in the figure, the present invention provides a high-density liquid-cooled energy storage cabinet, which includes a liquid-cooled energy storage cabinet body 1, and also includes a bracket base 2, the bracket base 2 is installed inside the liquid-cooled energy storage cabinet body 1; a connecting column 9, the connecting column 9 is symmetrically rotated at both ends inside the bracket base 2; a sliding mechanism 3, the sliding mechanism 3 is arranged on the surface of the connecting column 9, the sliding mechanism 3 includes a first sliding component 301, a second sliding component 302 and a connecting spring 303, the first sliding component 301 is slidably connected to the second sliding component 302, and both ends of the connecting spring 303 are respectively connected to the first sliding component 301 and the second sliding component 302; a transmission mechanism 4, the transmission mechanism 4 is arranged at one end of the connecting column 9 and is used to drive the connecting column 9 to rotate; a second bracket 6 and a third bracket 7, the second bracket 6 and the third bracket 7 are arranged up and down and both slide inside the bracket base 2, and the third bracket 7 is used to drive the transmission mechanism 4 to move; a first bracket 5, the first bracket 5 is rotatably connected to the top of the second bracket 6; a fixing plate 8, the fixing plate 8 is arranged on the second bracket 6 and extends into the first bracket 5; a thread strip is arranged on the surface of the connecting column 9, the pitch of one end of the thread strip is greater than that of the other end, and the connecting spring 303 is sleeved on the surface of the connecting column 9 and is adapted to the pitch of the thread strip on the surface of the connecting column 9.

[0037] By pulling the third bracket 7 outwards, the connecting column 9 can be driven to rotate through the transmission mechanism 4, thereby driving the sliding mechanism 3 to move. When the sliding mechanism 3 moves, it can drive the second bracket 6 and the first bracket 5 to move synchronously, realizing the removal of the first bracket 5, the second bracket 6, the third bracket 7 and the battery pack from the bracket base 2. And because the pitches of the two ends of the thread strip on the surface of the connecting column 9 are different, when the sliding mechanism 3 is located at the end of the thread strip on the surface of the connecting column 9 with a shorter pitch, the moving speeds of the first bracket 5 and the second bracket 6 slow down, thus playing a warning effect. And at this time, relative sliding occurs between the second bracket 6 and the third bracket 7, increasing the moving resistance, thereby reducing the inertia and preventing the inertia of the battery pack movement from damaging both ends of the slide rail.

[0038] As Figure 7 shown in the figure, the second sliding component 302 includes a second sliding seat 3021 and a pressing block 3022, the second sliding seat 3021 is connected to the pressing block 3022 through a first connecting block, and the first sliding component 301 is connected to the second bracket 6 through a second connecting block.

[0039] When the second sliding seat 3021 moves to the end with a shorter pitch of the threaded strip on the surface of the connecting column 9, it can move into the first sliding assembly 301, so that the extrusion block 3022 can slide on the surface of the second bracket 6. When the extrusion block 3022 moves, it can extrude the first bracket 5 to turn it upward, so as to realize that when the battery pack is about to be taken out of the bracket seat 2, it is driven by the first bracket 5 to turn upward. At this time, when the battery pack is pulled out, the battery pack initially has an inclination angle. It should be noted that when the battery pack is pulled out from the bracket, generally only one end of the battery pack is pulled. The other end will fall due to gravity after detaching from the bracket, making the horizontal battery pack become vertical. Due to the large inertia, it is easy to cause the battery pack to fall before the maintenance personnel can react in time, increasing the probability of battery pack damage. By initially giving the battery pack an inclination angle, the amplitude of swing required after the battery pack detaches from the first bracket 5 is reduced, thereby reducing the inertia and the damage risk caused by the battery pack falling.

[0040] As Figure 5 、 8 、9 shows, the second bracket 6 includes a bracket plate 601, a fixed shaft 602 and a sliding groove 603. The bracket plate 601 is connected to the first sliding assembly 301 through a second connecting block. The fixed shaft 602 is fixedly installed at one end of the bracket plate 601. The sliding grooves 603 are symmetrically opened on the surface of the bracket plate 601. The extrusion block 3022 is slidably arranged inside the sliding groove 603; a convex block located inside the sliding groove 603 is further provided at the bottom of the first bracket 5, and one end of the convex block close to the extrusion block 3022 is inclined.

[0041] The arranged sliding groove 603 enables the extrusion block 3022 to move therein, and a convex block is provided at the bottom of the first bracket 5, and the convex block is also located in the sliding groove 603. When the second sliding assembly 302 moves into the first sliding assembly 301, the extrusion block 3022 synchronously extrudes the convex block at the bottom of the first bracket 5, so as to realize the flipping of the first bracket 5 on the second bracket 6 through the pressure.

[0042] As Figure 4 、 5 shows, the fixing plate 8 is threadedly connected to the surface of the fixed shaft 602. The number of the fixing plates 8 is two and they are symmetrically arranged at both ends of the fixed shaft 602; the first bracket 5 is hinged to the fixed shaft 602, and the fixing plate 8 is slidably connected to the first bracket 5 along the axial direction of the fixed shaft 602. The extrusion block 3022 can drive the first bracket 5 to rotate around the fixed shaft 602 as the central axis by moving and extruding the convex block at the bottom of the first bracket 5.

[0043] The set fixing plate 8 can be moved on the fixing axis 602 by the rotation of the first bracket 5, and the battery pack is placed on the first bracket 5. When the first bracket 5 is flipped upward with the fixing axis 602 as the axis, the two fixing plates 8 move away from each other, that is, the fixation of the battery pack is released. When the first bracket 5 is flipped downward with the fixing axis 602 as the axis to return to being parallel, the two fixing plates 8 move toward each other, that is, the fixing plate 8 fixes the battery pack through pressure, thereby achieving an automatic fixation effect. It is worth mentioning that the surface of the fixing plate 8 is provided with rubber, which can not only provide friction but also prevent excessive pressure on the battery pack through deformation.

[0044] like Figure 3 , 4 6, the transmission mechanism 4 includes a synchronization component 401, a first bevel gear 402, a matching component 403 and a toothed plate 404. The first bevel gear 402 is transmission-connected to the connecting column 9 through the synchronization component 401. The first bevel gear 402 is meshed with the matching component 403. The matching component 403 is meshed with the toothed plate 404. The toothed plate 404 is mounted on the side of the third bracket 7; the matching component 403 includes a second bevel gear 4031 and a gear 4032. The second bevel gear 4031 is fixedly connected to the gear 4032. The second bevel gear 4031 meshes with the first bevel gear 402, the gear 4032 meshes with the tooth plate 404, and the matching component 403 is rotatably connected to the inside of the bracket seat 2; when the connecting column 9 rotates, it can drive the first sliding component 301, the second sliding component 302 and the connecting spring 303 to move inside the bracket seat 2 along the axial direction of the connecting column 9. When the connecting spring 303 is located at the end with a shorter pitch of the threaded strip on the surface of the connecting column 9, it is in a compressed state, and at this time, the second sliding component 302 moves toward the inside of the first sliding component 301.

[0045] The synchronous component 401 is specifically a transmission form of a synchronous belt and a synchronous wheel. Since the pitches of the two ends of the threaded strips on the surface of the connecting column 9 are different, that is, when the connecting column 9 rotates, the movement of the second bracket 6 is first fast and then slow, and the gear plate 404 drives the matching component 403 to rotate at a fixed amplitude. This causes relative sliding between the second bracket 6 and the third bracket 7 when the sliding mechanism 3 is located at the end with a shorter pitch of the threaded strips on the surface of the connecting column 9, thereby increasing the resistance to movement and reducing inertia, preventing the inertia of the battery pack movement from damaging the two ends of the slide rail.

[0046] The working principle and use process of the present invention:

[0047] When disassembling and overhauling, first pull the third bracket 7 outwards. The toothed plate 404 fixed to the third bracket 7 can drive the rotating of the matching assembly 403. The matching assembly 403 drives the first helical gear 402 to rotate. The first helical gear 402 drives the connecting column 9 to rotate through the synchronous assembly 401. When the connecting column 9 rotates, it drives the overall movement of the sliding mechanism 3. The sliding mechanism 3 moves on the surface of the connecting column 9 from the end with a larger pitch of the threaded strip to the end with a smaller pitch.

[0048] During the movement of the sliding mechanism 3, the sliding mechanism 3 synchronously drives the second bracket 6 and the first bracket 5 to move, so that the battery pack arranged on the first bracket 5 gradually moves out. When the sliding mechanism 3 moves to the end with a smaller pitch of the threaded strip on the surface of the connecting column 9, the connecting spring 303 is gradually compressed, and the second sliding seat 3021 moves into the first sliding assembly 301. The second sliding seat 3021 drives the extrusion block 3022 to extrude the convex block at the bottom of the first bracket 5, so that the first bracket 5 is turned upwards with the fixed shaft 602 as the axis. Synchronously, since the fixing plate 8 is threadedly connected to the surface of the fixed shaft 602 and one end is arranged inside the first bracket 5, when the first bracket 5 is turned, the fixing plate 8 also turns accordingly. The two fixing plates 8 arranged at both ends of the fixed shaft 602 move away from each other synchronously during the turning process, releasing the fixation of the battery pack.

[0049] When the sliding mechanism 3 moves to the end with a smaller pitch of the threaded strip on the surface of the connecting column 9, it will be difficult to pull the third bracket 7, which reminds the operator that the maximum value is about to be reached, and the applied pulling force can be gradually reduced.

[0050] It should be noted that in this article, relational terms such as first and second are only used to distinguish one entity or operation from another entity or operation, and do not necessarily require or imply any actual relationship or order between these entities or operations. Moreover, the term "comprising", "including" or any other variant thereof is intended to cover non-exclusive inclusion, so that a process, method, article or device including a series of elements not only includes those elements, but also includes other elements not expressly listed, or also includes elements inherent to such process, method, article or device.

[0051] Although the embodiments of the present invention have been shown and described, for those of ordinary skill in the art, it can be understood that various changes, modifications, substitutions and variations can be made to these embodiments without departing from the principle and spirit of the present invention. The scope of the present invention is defined by the appended claims and their equivalents.
