Description

Technical Field

[0001] This utility model relates to the field of batteries, and more particularly to battery racks and energy storage devices. Background Technology

[0002] As electrochemical energy storage systems develop towards larger capacity and higher energy density, the height of battery racks, as the core structural components that support battery modules, has increased significantly to meet the requirements of multi-level module stacking.

[0003] Due to unavoidable machining tolerances and assembly gaps in the various connecting parts of the rack (such as column interfaces and beam mounting surfaces), small errors in multiple levels of components in the height direction will accumulate, eventually leading to an excessive clearance between the bottom of the battery rack and the mounting surface (usually the ground). This causes the product to wobble easily, resulting in low installation stability of the battery rack. Utility Model Content

The gap adjustment component has an adjustment channel. The adjustment channel has a large-diameter end at a position away from the mounting plane. The gap adjustment assembly is screwed onto the base. The gap adjustment assembly has an adjustment cone. The gap adjustment assembly is inserted into the adjustment channel. When the gap adjustment assembly rotates on the base, it drives the adjustment cone to insert into or retract from the adjustment channel.

[0008] The adjusting cone rests against the inner wall of the adjusting channel, and when the adjusting cone slides toward the large-diameter end within the adjusting channel, the gap adjusting member moves along the through hole toward the mounting plane.

[0009] Preferably, in the length extension direction of the adjustment channel, the width of the adjustment channel gradually decreases, thereby forming a small diameter end and a large diameter end in the length extension direction of the adjustment channel, wherein the distance from the small diameter end to the mounting plane is less than the distance from the large diameter end to the mounting plane.

[0010] Preferably, the gap adjustment assembly includes an adjusting threaded component and an adjusting rod. The adjusting threaded component is screwed onto the base, and the adjusting rod is fixedly connected to the end of the adjusting threaded component. The adjusting rod is inserted into the adjustment channel, and the adjusting cone is located on the adjusting rod.

[0011] When the adjusting threaded component rotates on the base, it drives the adjusting rod to move in and out of the adjusting channel, thereby causing the adjusting rod to move the adjusting cone.

[0012] Preferably, the adjusting cone is disposed at the end of the adjusting rod, and the adjusting cone has a connecting hole at its center, into which the adjusting threaded part is inserted.

[0013] Preferably, the adjusting rod is in the shape of a long cylinder.

[0014] Preferably, the base also has through holes;

[0015] The gap adjustment mechanism further includes a threaded ring, which is fixedly mounted on the base and aligned with the through hole. The gap adjustment component passes through the through hole and the threaded ring, and is screwed to the inner ring of the threaded ring.

[0016] Preferably, the gap adjusting component includes a top support post and a guide head, the top support post being connected to the guide head, the top support post being slidably disposed within the through hole, the adjusting channel being located on the guide head, and the size of the guide head being larger than the diameter of the through hole; and / or

[0017] The base is provided with a guide cylinder, which surrounds the through hole, and the gap adjustment component is slidably inserted into the guide cylinder.

[0018] Preferably, the base has a plurality of through holes;

[0019] The battery rack includes multiple gap adjustment mechanisms, each gap adjustment component is slidably disposed in each of the through holes, each gap adjustment component is provided with an adjustment channel, and each adjustment channel is provided with a large diameter end;

[0020] Each of the gap adjustment components is screwed onto the base, and each gap adjustment component is provided with an adjustment cone. Each gap adjustment component is inserted into each of the adjustment channels in a corresponding manner.

[0021] This utility model also provides an energy storage device, including a frame body, a plurality of battery modules and the energy storage device, wherein the frame body includes a bottom frame, a top frame, a plurality of vertical bars and a plurality of horizontal bars;

[0022] The bottom frame is disposed on the base, one end of each vertical rod is connected to the bottom frame, the other end of each vertical rod is connected to the top frame, each horizontal rod is disposed on each vertical rod, and each horizontal rod defines a plurality of battery cavities in the length extension direction of the vertical rod, and each battery module is disposed in each of the battery cavities.

[0023] Preferably, the energy storage device further includes an intermediate connection module, which includes at least one intermediate connection plate and a plurality of intermediate connection bolts. Each intermediate connection plate is provided with a plurality of intermediate connection bolts, some of which are screwed to the frame body, and the remaining intermediate connection bolts are screwed to the base; and / or

[0024] The energy storage device further includes a fixed connection module, which includes at least one L-shaped fixing plate and several fixed connection bolts. The L-shaped fixing plate abuts against the vertical mounting surface and the vertical rod, and each of the fixed connection bolts is respectively disposed on the L-shaped fixing plate. Some of the fixed connection bolts are screwed to the vertical mounting surface, and the remaining fixed connection bolts are screwed to the vertical rod.

[0025] The following are the beneficial effects of implementing this utility model:

[0026] This utility model relates to a battery rack and an energy storage device, the energy storage device including the battery rack. On the battery rack, a gap adjustment component is slidably embedded in a through hole in the base, and combined with the large-diameter end structure of its adjustment channel, when the gap adjustment component rotates, the adjustment cone slides along the adjustment channel towards the large-diameter end, driving the gap adjustment component to move along the through hole towards the mounting plane, ultimately causing the gap adjustment component to pass through the through hole and be held against the mounting plane, completely eliminating the fit gap between the base and the mounting plane, thereby solving the problem of battery rack wobbling caused by gaps.

[0027] Furthermore, through the threaded engagement between the gap adjustment component and the base, rotational motion is converted into axial displacement of the adjustment cone. Then, through the engagement of the cone surface with the large-diameter end, radial force is converted into vertical displacement of the gap adjustment component, achieving precise adjustment of the installation gap. Reverse rotation of the gap adjustment component allows the adjustment cone to retract from the large-diameter end, releasing the pressure on the mounting surface and facilitating disassembly, maintenance, or repositioning of the frame, thus balancing stability and ease of operation.

[0051] Figure 1 The diagram illustrates a battery rack 10 in some embodiments of the present invention, which is disposed on a mounting surface (such as the ground or other surface for mounting the battery rack 10). The battery rack 10 includes a base 1 and a gap adjustment mechanism 2, the base 1 resting against the mounting surface, and the gap adjustment mechanism 2 disposed on the base 1.

[0052] It should be noted that the mounting plane provides the mounting reference surface for the battery rack 10 and bears the overall load of the battery rack 10. The mounting plane is the mounting position of the battery rack 10.

[0053] like Figures 1 to 8 As shown, a through hole 11 is provided on the base 1. The gap adjustment mechanism 2 includes a gap adjustment component 21 and a gap adjustment assembly 22. The gap adjustment component 21 is slidably disposed in the through hole 11. An adjustment channel 213 is provided on the gap adjustment component 213. A large-diameter end 2131 is provided in the adjustment channel 213 at a position away from the mounting plane. The gap adjustment assembly 22 is screwed onto the base 1. An adjustment cone 223 is provided on the gap adjustment assembly 22. The gap adjustment assembly 22 is inserted into the adjustment channel 213. When the gap adjustment assembly 22 rotates on the base 1, it drives the adjustment cone 223 to insert or retract into the adjustment channel 213. The adjustment cone 223 abuts against the inner wall of the adjustment channel 213. When the adjustment cone 223 slides towards the large-diameter end 2131 in the adjustment channel 213, the gap adjustment component 21 moves along the through hole 11 towards the mounting plane.

[0054] Understandably, the base 1 provides a supporting foundation for the battery rack 10 and stably transfers the overall load to the mounting surface, ensuring the stability of the battery rack 10. The through hole 11 accommodates the sliding movement of the gap adjustment member 21, allowing the gap adjustment member 21 to move along its axial direction to achieve position adjustment.

[0055] The gap adjustment component 21 is used to change its own position by sliding, so that the gap adjustment component 21 can pass through the through hole 11 and abut against the mounting surface, thereby providing stable and reliable support between the base 1 and the mounting surface. In other words, the mounting surface supports the gap adjustment component 22 through the gap adjustment component 21, and the gap adjustment component 22 supports the base 1. Ultimately, the base 1 can be provided with stable and reliable support, avoiding excessive gap between the base 1 and the mounting surface, which would cause the battery frame 10 to shake. This improves the installation stability and reliability of the product and further avoids safety risks caused by shaking.

[0056] The opening of the adjustment channel 213 facilitates the insertion and withdrawal of the adjustment cone 223. The tapered inner wall of the adjustment channel 213 engages with the surface of the adjustment cone 223 to control the linear movement direction and distance of the gap adjustment component 21. The gap adjustment assembly 22 converts rotational motion into linear displacement via a screwed connection (to the base), driving the movement of the adjustment cone 223. The adjustment cone 223 abuts against the inner wall of the adjustment channel 213, generating radial thrust. When the adjustment cone 223 slides towards its larger diameter end, it pushes the gap adjustment component 21 along the through hole 11 towards the mounting plane, thereby reducing or eliminating the gap.

[0057] It should be noted that when the gap adjustment component 22 is rotated, causing the adjustment cone 223 to continuously insert into the adjustment channel 213, the adjustment cone 223 will also continuously insert into the adjustment channel 213. As the adjustment cone 223 abuts against the inner wall of the adjustment channel 213, with the further insertion of the adjustment cone 223, the large-diameter end 2131 of the adjustment channel 213 will continuously slide closer to the mounting plane. As the adjustment cone 223 is continuously inserted, the abutting position between the adjustment cone 223 and the adjustment channel 213 will continuously change, so that the larger radius portion of the adjustment cone 223 will continuously abut against the larger radius portion of the adjustment channel 213. This causes the extension of the gap adjustment component 21 outside the through hole 11 to gradually increase, allowing the gap adjustment component 21 to abut against the mounting plane to eliminate the mating gap.

[0058] Conversely, when the gap adjusting member 21 is already against the mounting surface, if the gap adjusting assembly 22 is rotated in the opposite direction, the gap adjusting assembly 22 will cause the adjusting cone 223 to move in the direction of exiting the adjusting channel 213. This will cause the radius of the part of the adjusting cone 223 that abuts against the adjusting channel 213 to gradually decrease, that is, to gradually abut against the adjusting channel 213 through the smaller radius part of the adjusting cone 223. In this way, the large diameter end 2131 will gradually move away from the gap adjusting assembly 22, causing the amount of gap adjusting member 21 protruding outside the through hole 11 to gradually decrease, and finally causing the gap adjusting member 21 to move away from the mounting surface.

[0059] like Figures 5 to 8 As shown, in some embodiments of the battery rack 10, the width W of the adjustment channel 213 gradually decreases in the length extension direction of the adjustment channel 213, thereby forming a small diameter end and a large diameter end in the length extension direction of the adjustment channel 213, and the distance from the small diameter end to the mounting plane is less than the distance from the large diameter end to the mounting plane.

[0060] Understandably, the width W of the adjustment channel 213 (i.e., the dimension perpendicular to its length extension direction) gradually decreases along its length extension direction L1 (the length extension direction of the adjustment channel 213). In this way, the adjustment channel 213 defines a relatively large diameter end 2131 and a relatively small diameter end 2132 in its own length extension direction L1.

[0061] The distance from the smaller diameter end 2132 to the mounting plane is less than the distance from the larger diameter end 2131 to the mounting plane. That is, in the installed state, the smaller diameter end 2132 is closer to the mounting plane than the larger diameter end 2131.

[0062] The inner wall contour of the adjusting channel 213 is adapted to the outer contour of the adjusting cone 223 on the gap adjusting assembly 22; as the adjusting cone 223 is continuously inserted into the adjusting channel 213, the cone surface of the adjusting cone 223 forms a complementary cone surface contact or wedge fit with the inner wall surface of the adjusting channel 213. When the adjusting cone 223 moves along the length of the adjusting channel 213 (especially towards the large diameter end 2131), the radial component force generated by the cone surface contact will drive the gap adjusting member 21 to move along the axial direction of the through hole 11.

[0063] Furthermore, the largest radius portion of the adjusting cone 223 can be configured to be larger than the largest radius within the adjusting channel 213, to prevent the adjusting cone 223 from directly passing through the adjusting channel 213.

[0064] like Figure 2 as well as Figures 5 to 8 As shown, in some embodiments of the battery rack 10, the gap adjustment assembly 22 includes an adjusting threaded component 221 and an adjusting rod 222. The adjusting threaded component 221 is screwed onto the base 1, and the adjusting rod 222 is fixedly connected to the end of the adjusting threaded component 221. The adjusting rod 222 is inserted into the adjusting channel 213, and the adjusting cone 223 is located on the adjusting rod 222. When the adjusting threaded component 221 rotates on the base 1, it drives the adjusting rod 222 to move in and out of the adjusting channel 213, thereby causing the adjusting rod 222 to move the adjusting cone 223.

[0065] Understandably, the adjusting threaded component 221 is directly screwed onto the base 1 via threads, thereby fixing and transmitting the rotational motion. The adjusting rod 222 is fixedly connected to the end of the adjusting threaded component 221, and the adjusting cone 223 is mounted on the adjusting rod 222. When the adjusting threaded component 221 rotates on the base 1, its thread engagement causes the adjusting rod 222 to move axially as a whole (entering and exiting the adjusting channel 213), thereby causing the adjusting cone 223 to slide relative to the adjusting channel 213.

[0066] It should be noted that the assembly process of the gap adjustment component 22 is simplified through the content of this embodiment. At the same time, the torque applied by the user can be directly converted into the movement of the adjustment cone 223 through the direct screw connection of the threaded part 221, which improves the torque transmission efficiency and enhances the accuracy and reliability of gap adjustment.

[0067] like Figure 8 As shown, in some embodiments of the battery rack 10, the adjusting cone 223 is disposed at the end of the adjusting rod 222, and the adjusting cone 223 has a connecting hole 2231 at the center, and the adjusting threaded part 221 is inserted into the connecting hole 2231.

[0068] Understandably, the adjusting rod 222 is directly inserted and fixed in the connecting hole 2231, forming a tight plug-in fit. The connecting hole 2231 serves as the interface between the adjusting cone 223 and the adjusting rod 222, ensuring that the adjusting rod 222 and the adjusting cone 223 move synchronously and avoid deviations caused by relative displacement.

[0069] It should be noted that the connection hole 2231 enables the quick assembly of the adjusting cone 223 and the adjusting threaded part 221, reducing the complexity of processing and installation, while enhancing the rigidity and torsional resistance of the overall structure and preventing loosening during adjustment.

[0070] like Figure 7 and Figure 8 As shown, in some embodiments of the battery rack 10, the adjusting rod 222 is in the shape of an elongated cylinder.

[0071] Understandably, the adjusting rod 222 is configured as a long cylinder to avoid unnecessary contact when it is inserted into the adjusting channel 213, ensuring that the lifting adjustment of the gap adjusting member 21 depends on the adjusting cone 223, or only on the adjusting cone 223, so that the gap adjustment is more precise and controllable.

[0072] like Figure 2 and Figure 3 As shown, in some embodiments of the battery rack 10, the base 1 also has through holes 12.

[0073] Please refer to the following: Figures 5 to 8 The gap adjustment mechanism 2 also includes a threaded ring 23, which is fixedly mounted on the base 1. The threaded ring 23 is aligned with the through hole 12. The gap adjustment component 22 passes through the through hole 12 and the threaded ring 23, and the gap adjustment component 22 is screwed to the inner ring of the threaded ring 23.

[0074] Understandably, a through hole 12 is formed on the base 1 and aligned with a fixedly mounted threaded ring 23. The gap adjustment assembly 22 passes through the through hole 12 and the threaded ring 23 in sequence, and the external thread of the gap adjustment assembly 22 is directly screwed into the inner thread of the threaded ring 23. The threaded ring 23 provides a thread engagement point, allowing the gap adjustment assembly 22 to move in a predetermined direction during rotation.

[0075] It should be noted that the threaded ring 23 can be configured to be integrally formed and set on the base 1, or it can be configured to be fixed on the base 1 by welding or other common connection methods in the prior art.

[0076] like Figures 4 to 8 As shown, in some embodiments of the battery rack 10, the gap adjustment member 21 includes a top support post 211 and a guide head 212. The top support post 211 is connected to the guide head 212. The top support post 211 is slidably disposed in the through hole 11. The adjustment channel 213 is located on the guide head 212. The size of the guide head 212 is larger than the diameter of the through hole 11.

[0077] Understandably, the top support post 211 is used to directly transmit the supporting force to the mounting plane, and its columnar structure adapts to the contour of the hole wall of the through hole 11 to achieve a sliding connection. The guide head 212 is larger than the diameter of the through hole 11, which can prevent the guide head 212 from being inserted into the through hole 11 and ensure that the gap adjustment member 21 is always constrained on the base 1 during sliding.

[0078] like Figure 3 , Figure 4 and Figure 8 As shown, in some embodiments of the battery rack 10, a guide cylinder 13 is provided on the base 1, the guide cylinder 13 surrounds the through hole 11, and the gap adjustment member 21 is slidably inserted into the guide cylinder 13.

[0079] Understandably, the guide cylinder 13 provides a cylindrical guide surface that matches the contour of the gap adjuster 21, forming a reliable sliding connection to prevent accidental offset. The through hole 11 defines the basic path, and the guide cylinder 13 further constrains radial offset, ensuring the straightness of the movement trajectory of the gap adjuster 21.

[0080] It should be noted that the guide cylinder 13 can ensure the accuracy of the movement of the gap adjustment component 21 and prevent deviation, while also improving the resistance to eccentric load and avoiding jamming caused by lateral force.

[0081] like Figure 1 , Figure 2 and Figure 8 As shown, in some embodiments of the battery rack 10, the base 1 has a plurality of through holes 11;

[0082] The battery rack 10 includes multiple gap adjustment mechanisms 2, each gap adjustment component 21 is slidably disposed in each through hole 11, and each gap adjustment component 21 is provided with an adjustment channel 213, and each adjustment channel 213 is provided with a large diameter end.

[0083] Each gap adjustment component 22 is screwed onto the base 1. Each gap adjustment component 22 is provided with an adjustment cone 223. Each gap adjustment component 22 is inserted into each adjustment channel 213 in a corresponding manner.

[0084] Understandably, in this type of embodiment, adjustment points (i.e., through holes 11) are set at different positions on the base 1, and each gap adjustment mechanism 2 can be operated independently, thereby achieving targeted elimination of local gaps.

[0085] It should be noted that staff can flexibly adjust the corresponding gap adjustment mechanism 2 according to the actual working conditions at the construction site, thereby ensuring the installation stability and reliability of the product. Figure 9 The diagram illustrates an energy storage device 20 in some embodiments of the present invention. The energy storage device 20 is used to store and output electrical energy. The energy storage device 20 includes a frame body 30, several battery modules, and the energy storage device 20 itself. The frame body 30 includes a bottom frame 31, a top frame 32, several vertical bars 33, and several horizontal bars 34.

[0086] The bottom frame 31 is set on the base 1. One end of each vertical rod 33 is connected to the bottom frame 31, and the other end of each vertical rod 33 is connected to the top frame 32. Each horizontal rod 34 is set on each vertical rod 33. Each horizontal rod 34 defines a number of battery cavities 35 in the length extension direction of the vertical rod 33. Each battery module is set in each battery cavity 35.

[0087] Understandably, the base frame 31 serves as the foundational load-bearing platform for the entire energy storage device 20, transferring the battery module load to the base 1 and mounting plane. The top frame 32 is positioned parallel above the base frame 31, forming a closed top structure. Vertical rods 33 are vertically distributed between the base frame 31 and the top frame 32, with the bottom end of each rod fixedly connected to the base frame 31 and the top end fixedly connected to the top frame 32, forming the longitudinal load-bearing supports of the frame body 30. Horizontal bars 34 connect horizontally to adjacent vertical bars 33, spaced apart along the length of the vertical bars 33, defining a battery cavity 35 between every two layers of horizontal bars 34. The dimensions of the battery cavity 35 are adapted to the shape of the battery module. The battery module stores electrical energy and releases it when needed.

[0088] like Figure 9 and Figure 10As shown, in some embodiments of the energy storage device 20, the energy storage device 20 further includes an intermediate connection module 40. The intermediate connection module 40 includes at least one intermediate connection plate 41 and a plurality of intermediate connection bolts 42. Each intermediate connection plate 41 is provided with a plurality of intermediate connection bolts 42. Some intermediate connection bolts 42 are screwed to the frame body 30, and the remaining intermediate connection bolts 42 are screwed to the base 1.

[0089] Understandably, the intermediate connecting plate 41 is horizontally spanned between the bottom frame 31 and the base 1 of the frame body 30. The intermediate connecting bolts 42 are divided into two groups. One group of connecting bolts 42 passes through the connecting plate 41 and is screwed onto the bottom frame 31, while the other group of connecting bolts 42 passes through the connecting plate 41 and is screwed onto the base 1.

[0090] It should be noted that the connecting plate 41 serves as a rigid transition, securely connecting the frame body 30 to the base 1.

[0091] like Figure 9 and Figure 11 As shown, in some embodiments of the energy storage device 20, the energy storage device 20 further includes a fixed connection module 50. The fixed connection module 50 further includes at least one L-shaped fixing plate 51 and several fixed connection bolts 52. The L-shaped fixing plate 51 abuts against the vertical mounting surface and the vertical rod 33 respectively. Each fixed connection bolt 52 is respectively disposed on the L-shaped fixing plate 51. Some of the fixed connection bolts 52 are screwed to the vertical mounting surface, and the remaining fixed connection bolts 52 are screwed to the vertical rod 33.

[0092] Understandably, one part of the L-shaped fixing plate 51 is attached to the surface of the vertical rod 33 of the frame body 30, while the other part is attached to the external vertical mounting surface (such as a wall). The fixing bolts 52 are divided into two groups. One group of fixing bolts 52 passes through the horizontal edge of the L-shaped plate and is screwed onto the vertical rod 33, while the other group of fixing bolts 52 passes through the vertical edge of the L-shaped plate and is screwed onto the vertical mounting surface.

[0093] It should be noted that the content of this embodiment can limit the relative position of the frame body 30 and the vertical mounting surface to a certain extent, prevent the frame body 30 from tipping over, and further improve the installation stability of the product.

[0094] The following are the beneficial effects of implementing this utility model:

[0095] This utility model relates to a battery rack and an energy storage device, the energy storage device including the battery rack. On the battery rack, a gap adjustment component is slidably embedded in a through hole in the base, and combined with the large-diameter end structure of its adjustment channel, when the gap adjustment component rotates, the adjustment cone slides along the adjustment channel towards the large-diameter end, driving the gap adjustment component to move along the through hole towards the mounting plane, ultimately causing the gap adjustment component to pass through the through hole and be held against the mounting plane, completely eliminating the fit gap between the base and the mounting plane, thereby solving the problem of battery rack wobbling caused by gaps.

[0096] Furthermore, through the threaded engagement between the gap adjustment component and the base, rotational motion is converted into axial displacement of the adjustment cone. Then, through the engagement of the cone surface with the large-diameter end, radial force is converted into vertical displacement of the gap adjustment component, achieving precise adjustment of the installation gap. Reverse rotation of the gap adjustment component allows the adjustment cone to retract from the large-diameter end, releasing the pressure on the mounting surface and facilitating disassembly, maintenance, or repositioning of the frame, thus balancing stability and ease of operation.
