Description

Technical Field

[0001] The present invention belongs to the technical field of energy storage battery pack installation, and in particular relates to a fully-limited guide rail structure for a battery pack of an energy storage cabinet. Background Art

[0002] Energy storage technology can address the intermittent and unstable nature of renewable energy and balance grid loads. To adapt to the development of green energy, various energy storage devices are gaining popularity and playing a vital role in the grid supply and demand chain. Electrochemical energy storage remains the most widely used energy storage technology.

[0003] Electrochemical energy storage battery packs are lithium iron phosphate batteries, which are classified as dangerous goods for transportation. In addition, due to the large mass of such battery packs, each weighing more than 300 kilograms, they need to be securely fixed during transportation to prevent them from falling and causing secondary disasters.

[0004] Energy storage cabinets currently available on the market are semi-enclosed structures, meaning only the front door can be opened, through which the battery pack is loaded. Consequently, only the front end of the battery pack can be restrained and limited by fixed structures, while the rear end cannot be fixed, resulting in a large degree of freedom at the rear end of the battery pack. During transportation, the rear end is prone to significant bumps and jolts, which can damage the front end of the battery pack, causing fatigue fractures. The battery pack can then completely lose its secure position, making it prone to slipping and potentially causing serious accidents such as explosions and fires. Summary of the Invention

[0005] The object of the present invention is to provide a fully-limited guide rail structure for a battery pack of an energy storage cabinet, so as to solve the problem of poor fixation of the battery pack.

The upper guide plates include an inclined plate with an upper end inclined outward, and a vertical plate located above the inclined plate and in contact with the inner wall of the upper guide rail side plate.

[0015] Furthermore, a side guide plate is provided at the front end of the side limiting plate, and the front end of the side guide plate is inclined outward.

[0016] Furthermore, the front end of the horizontal plate of the upper guide rail is provided with a downwardly folded front bending plate I, and the front end of the pressure strip is provided with an inwardly folded front limit plate, the front limit plate is provided in front of the front bending plate I and the two are detachably connected;

[0020] Furthermore, the guide rail assembly also includes a lower guide rail arranged below the upper guide rail, and the lower guide rail is an inverted L-shaped structure with an opening facing inward. The rear end of the side panel of the lower guide rail is provided with an inward-folded rear bending plate II, and the rear end of the horizontal plate of the lower guide rail is supported on the rear bending plate II.

[0021] Furthermore, a plurality of angled supports are provided on the inner side of the lower guide rail.

[0022] After adopting the above technical solution, the present invention has the following beneficial effects:

[0023] The present invention uses a symmetrically arranged full-limit guide rail structure to constrain and limit the battery pack in multiple dimensions, such as up and down, front and back, and left and right.

DETAILED DESCRIPTION

[0036] To make the purpose, technical solutions, and advantages of the embodiments of the present invention more clear, the technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without making creative efforts shall fall within the scope of protection of the present invention.

[0037] Therefore, the following detailed description of the embodiments of the present invention provided in the accompanying drawings is not intended to limit the scope of the invention as claimed, but rather merely represents selected embodiments of the present invention. All other embodiments derived by persons of ordinary skill in the art based on the embodiments of the present invention without creative effort are also within the scope of protection of the present invention.

[0038] like Figure 1-10 As shown, a battery pack full-limit guide rail structure of an energy storage cabinet is provided with a full-limit guide rail structure on both sides of the battery pack 31, and the two full-limit guide rail structures cooperating with the same battery pack 31 are symmetrically arranged on the left and right, and limit the up and down, left and right, and front and back directions of the battery pack 31; the full-limit guide rail structure includes a guide rail assembly 1 and a pressure strip 2, the guide rail assembly 1 is arranged at the flange surface 32 on the side of the battery pack 31, and is used to limit the side, bottom and rear end of the flange surface 32; the two ends of the pressure strip 2 cooperate with the guide rail assembly 1 and are pressed on the flange surface 32, and are used to limit the top and front end of the flange surface 32.

[0039] The battery pack 31 is installed in the energy storage cabinet 33 , wherein the bottom periphery of the battery pack 31 is provided with a flange surface 32 for fixing it, wherein the front ends of the flange surfaces 32 on both sides of the battery pack 31 are provided with flange brackets 34 .

[0040] In this embodiment, the two fully-positioned guide rail structures associated with the same battery pack 31 respectively cooperate with the flange surfaces 32 and flange brackets 34 on both sides of the battery pack 31 to achieve all-round, multi-dimensional restraint of the battery pack 31. Therefore, the flange surfaces 32 associated with the fully-positioned guide rail structures below refer to the flange surfaces 32 on the side surfaces of the battery pack 31.

[0041] The pressure strip 2 is arranged in the front-to-back direction. In order to completely cover the flange surface 32 on the side of the battery pack 31 , the length of the pressure strip 2 is greater than the length of the battery pack 31 in the front-to-back direction.

[0042] In order to constrain and limit the battery pack 31 in the vertical direction, the guide rail assembly 1 includes an L-shaped upper guide rail 11 with an inward opening, and the flange surface 32 is supported on a horizontal plate of the upper guide rail 11 .

[0043] The upper guide rail 11 is arranged in the front and rear directions, and the flange surface 32 is supported on the horizontal plate of the upper guide rail 11. By cooperating with the pressure strip 2 pressed on the flange surface 32 and the upper guide rail 11, the vertical amplitude of the battery pack 31 during transportation can be reduced, the impact energy can be reduced, and then the flange surface 32 and the battery pack 31 can be constrained and limited in the upper and lower directions.

[0044] A connecting hole I12 is provided on the side panel of the upper guide rail 11 , and the upper guide rail 11 is detachably connected to the two cabinet columns 35 on the same side of the energy storage cabinet 33 via bolts installed in the connecting hole I12 .

[0045] In order to constrain and limit the battery pack 31 in the left and right directions, the guide rail assembly 1 includes a side limiting plate 13 provided on the upper guide rail 11 and located outside the flange surface 32 .

[0046] The side limit plates 13 are arranged in the front-to-rear direction and are attached to the outer side of the flange surface 32. The side limit plates 13 of the two full-limit guide rail structures can cooperate to form a micro gap between the guide rail assembly 1 and the flange surface 32, effectively reducing the amplitude of the battery pack 31 in the left and right directions, and realizing the constraint and limitation of the battery pack 31 in the left and right directions.

[0047] In the existing battery pack 31 fixing structure, the gap between the flange surfaces 32 on both sides of the battery pack 31 and the fixing structure is generally about 15 mm. During transportation, the battery pack 31 is very likely to shake in the left and right directions, which in turn causes damage to the battery pack 31. In this embodiment, through the setting of the side limit plate 13, the distance between it and the flange surface 32 can be reduced to 1-2 mm, that is, the gap is reduced by more than 86%, which not only effectively reduces the amplitude of the battery pack 31 in the left and right directions during transportation, but also ensures that the battery pack 31 can be smoothly assembled into the two relatively set full-limit guide rail structures.

[0048] Preferably, a plurality of plug holes Ⅰ14 are provided on the upper guide rail 11, and a plug plate Ⅰ15 is provided on the lower edge of the side limit plate 13 to fit in the plug hole Ⅰ14. This facilitates the fitting and positioning between the side limit plate 13 and the upper guide rail 11, and at the same time improves the stability of the fitting between the two.

[0049] Preferably, in order to further ensure the positioning of the side limit plate 13 on the upper guide rail 11 and the stability of the cooperation between the two, an outward-folded plug-in plate Ⅱ16 is provided on the upper side of the rear end of the side limit plate 13, and a plug-in hole Ⅱ17 that cooperates with the plug-in plate Ⅱ16 is provided on the side plate of the upper guide rail 11.

[0050] In order to increase the structural strength of the side limit plate 13 and the entire guide rail assembly 1, multiple upper guide plates 18 are provided on the upper edge of the side limit plate 13. The upper guide plates 18 include an inclined plate with an upper end inclined outward, and a vertical plate located above the inclined plate and in contact with the inner wall of the side plate of the upper guide rail 11.

[0051] The upper guide plate 18 and the side limit plate 13 are integrally arranged, and a gap is left between the side limit plate 13 and the side plate of the upper guide plate 18. Through the setting of the inclined plate, the vertical plate at the top of the upper guide plate 18 can fit with the inner wall of the vertical plate of the upper guide rail 11.

[0052] When the battery pack 31 is installed from top to bottom, the structure of the inclined plate can play a good guiding role and achieve centering guided installation.

[0053] Preferably, a U-shaped notch 123 is provided at the top of the vertical plate. When the side limit plate 13 and the upper guide rail 11 are connected by welding, welding can be performed in the U-shaped notch 123, which can ensure that the side limit plate 13 and the upper guide rail 11 are stably connected without generating welding bumps on the surface, thereby ensuring the flatness of the surface of the guide rail assembly 1.

[0054] The battery pack 31 can also be loaded from the front door of the energy storage cabinet 33. In order to guide the loading of the battery pack 31, a side guide plate 19 is provided at the front end of the side limit plate 13, and the front end of the side guide plate 19 is inclined outward.

[0055] The provision of the side guide plates 19 makes it easier for the battery pack 31 to be pushed into the energy storage cabinet 33 and also serves as a centering guide.

[0056] In order to constrain and limit the front end of the battery pack 31, the front end of the horizontal plate of the upper guide rail 11 is provided with a front bending plate Ⅰ110 that folds downward, and the front end of the pressure strip 2 is provided with a front limiting plate 21 that folds inward. The front limiting plate 21 is provided on the front side of the front bending plate Ⅰ110 and the two are detachably connected.

[0057] The front limiting plate 21 is located in front of the flange bracket 34 to constrain and limit the flange surface 32 and the front end of the battery pack 31 .

[0058] Preferably, the front limiting plate 21 is arranged in close contact with the front bending plate Ⅰ110 to facilitate positioning of the pressure strip 2 in the front and rear directions.

[0059] The front bending plate I110 is provided with a connecting hole II111, and the front limit plate 21 is provided with a connecting hole III22 corresponding to the connecting hole II111. The front bending plate I110 and the front limit plate 21 are connected by bolts assembled in the above two connecting holes.

[0060] In order to achieve the connection between the front limiting plate 21 and the battery pack 31 , the front limiting plate 21 is detachably connected to the flange bracket 34 at the front end of the flange surface 32 .

[0061] The front limit plate 21 is provided with a connecting hole IV23 , which cooperates with the threaded hole on the flange bracket 34 , and the front limit plate 21 and the flange bracket 34 are detachably connected by bolts assembled therein.

[0062] Preferably, the inner edge of the front stop plate 21 is provided with a forward-folding front bending plate II 27, which is provided with a through hole 28. The design of the front bending plate II 27 can effectively improve the strength of the front stop plate 21, and the through hole 28 is designed to facilitate the fixing of the wiring harness on the battery pack 31. For example, a cable tie can be passed through the through hole 28 and then used to tie and secure the wiring harness of the battery pack 31.

[0063] In order to achieve the positioning fit between the front part of the pressure strip 2 and the guide rail assembly 1, the rear side of the front limit plate 21 is provided with an outward folded avoidance portion 24, the bottom of the avoidance portion 24 is provided with a latching tooth 25, and the horizontal plate of the upper guide rail 11 is provided with a front latching hole 112 that cooperates with the latching tooth 25.

[0064] The avoidance portion 24 is designed to avoid the flange bracket 34 at the front end of the flange surface 32. Through the cooperation of the latching teeth 25 and the front latching hole 112, it can not only realize the cooperation and positioning of the pressure strip 2 and the guide rail assembly 1, but also improve the strength of the front and rear direction limiting ability of the battery pack 31, reduce the impact force of the front and rear limits, and ensure the fixing effect of the full-limit guide rail structure on the battery pack 31.

[0065] In order to constrain and limit the rear end of the battery pack 31, the rear end of the horizontal plate of the upper guide rail 11 is provided with an upwardly folded rear bending plate Ⅰ113, and the rear bending plate Ⅰ113 is provided with a rear clamping hole 114, and the rear end of the pressure strip 2 can be fitted in the rear clamping hole 114.

[0066] Preferably, a plug-in portion 26 is provided at the rear end of the pressure strip 2, and the upper edge and lower edge of the plug-in portion 26 are structures that are inclined toward each other at the rear end, so that the plug-in portion 26 can be conveniently fitted into the rear card hole 114. At the same time, after the plug-in portion 26 is fitted into the rear card hole 114, the front end of the pressure strip 2 can be easily assembled into place.

[0067] The rear end of the flange surface 32 is placed against the rear bending plate Ⅰ113, so through the cooperation between the pressure strip 2 and the various parts of the upper guide rail 11, that is, the cooperation between the rear bending plate Ⅰ113 and the plug-in part 26, the cooperation between the latching tooth 25 and the front latching hole 112, and the cooperation between the front limit plate 21 and the front bending plate Ⅰ110, the constraint and limitation of the front and rear directions of the battery pack 31 are achieved.

[0068] In order to ensure the structural strength of the guide rail assembly 1, the guide rail assembly 1 also includes a lower guide rail 115 arranged below the upper guide rail 11. The lower guide rail 115 is an inverted L-shaped structure with an opening facing inward. The rear end of the side panel of the lower guide rail 115 is provided with an inward-folded rear bending plate II 116, and the rear end of the horizontal plate of the lower guide rail 115 is supported on the rear bending plate II 116.

[0069] The horizontal plate of the lower guide rail 115 is attached to the bottom of the horizontal plate of the upper guide rail 11 .

[0070] Preferably, in order to facilitate the coordination and positioning between the lower guide rail 115 and the side limit plate 13 and the upper guide rail 11, and at the same time ensure the stability of the coordination between the three, a plug hole IV122 corresponding to the plug hole I14 and the plug plate I15 is provided on the lower guide rail 115, and the lower end of the plug plate I15 passes through the plug hole I14 and extends into the plug hole IV122.

[0071] A connecting hole V117 is provided on the side panel of the lower guide rail 115, which cooperates with the threaded holes on the two cabinet columns 35 on the same side. By assembling the bolts in the connecting hole V177, a detachable connection between the lower guide rail 115 and the cabinet columns 35 can be achieved.

[0072] Preferably, the connection hole Ⅰ12 connected to at least one cabinet column 35 is a waist-shaped hole in the horizontal direction.

[0073] Preferably, the connecting hole III 22 is a waist-shaped hole in the vertical direction.

[0074] Preferably, the connection hole IV23 connected to at least one cabinet column 35 is a waist-shaped hole in the horizontal direction.

[0075] The connecting holes adopt a waist-shaped hole structure, which is conducive to the adjustment of distance errors and is more convenient during installation.

[0076] The cooperation between the rear bending plate II 116 and the horizontal rear end of the lower guide rail 115 can also improve the supporting strength of the guide rail assembly 1.

[0077] In order to further increase the strength of the guide rail assembly 1 , a plurality of angled supports 118 are provided on the inner side of the lower guide rail 115 .

[0078] A plug-in plate III119 is provided at the top of the inner end of the bevel support 118, and the plug-in plate III119 is plugged into the plug-in hole III120 on the horizontal plate of the lower guide rail 115. The setting of the plug-in plate III119 and the plug-in hole III120 can facilitate the matching and positioning between the bevel support and the lower guide rail.

[0079] A plug-in slot 121 is provided at the top of the angled support 118 opposite to the plug-in plate I15, and the plug-in plate I15 can pass through the plug-in hole I14 and the plug-in hole IV122 and fit into the plug-in slot 121 opposite to it, thereby realizing the positioning and fitting among the angled support 118, the upper guide rail 11, the lower guide rail 115 and the side limit plate 13.

[0080] The guide rail assembly 1 in this embodiment is connected by welding, that is, the connections between the upper guide rail 11, the lower guide rail 115 and the side limit plate 13 are all fixed by welding. Specifically, through the cooperation of the plug-in plate I15 and the plug-in hole I14, the cooperation of the plug-in plate II16 and the plug-in hole II17, the cooperation of the plug-in plate III119 and the plug-in hole III120, and the cooperation of the plug-in plate I15 and the plug-in slot 121, not only can the cooperation accuracy between the various components on the guide rail assembly 1 be guaranteed, but also each cooperation point can be used as a welding part, which effectively improves the connection stability between the various components while not generating welding bumps on the surface, thereby ensuring the flatness of the surface of the guide rail assembly 1.

[0081] When assembling the battery pack 31, first fix the guide rail assemblies 1 on the cabinet columns 35 in the energy storage cabinet 33 in a symmetrical manner, and then install the battery pack 31 on the corresponding two guide rail assemblies 1 in an upper or front-mounted manner, and then insert the plug-in portion 26 at the rear end of the pressure strip 2 into the corresponding rear clamping hole 114, and then rotate the front end of the pressure strip 2 downward so that it is pressed against the flange surface 32 on the side of the battery pack 31. At this time, the clamping teeth 25 are engaged in the front clamping hole 112, and the front limit plate 21 is placed on the front side of the front bending plate I110. Then, the front limit plate 21 is connected to the flange bracket 34 and the front bending plate I110 with bolts to achieve the constraint and limitation of the battery pack 31 up and down, front and back, and left and right.

[0082] The fully-limited guide rail structure of the present invention has a simple overall structure. It supports the battery pack 31 in a bilaterally symmetrical manner and can implement multi-dimensional constraints on the up and down directions, front and back directions, and left and right directions of the battery pack 31. During transportation, especially on the northwest highway where transportation conditions are relatively harsh, it avoids the problem of damage to the fixed structural parts of the battery pack 31, ensures the fixing effect of the battery pack 31, and improves the safety of transportation.

[0083] With the above-described preferred embodiments of the present invention as a guide, and with reference to the above description, relevant personnel are fully capable of making various changes and modifications without departing from the technical scope of this invention. The technical scope of this invention is not limited to the contents of the specification and must be determined according to the scope of the claims.
