Description

Technical Field

[0001] This invention relates to the field of energy storage equipment manufacturing technology, and more specifically, to a fixed component and an energy storage device having the same. Background Technology

[0002] Currently, during the processing of energy storage equipment, the processed battery packs need to undergo a clustering operation, which involves sequentially transferring multiple battery packs to the battery pack fixing structure inside the energy storage equipment to secure the battery packs and facilitate subsequent assembly steps.

[0003] However, existing technologies for securing battery packs during clustering typically employ only simple dual-rail structures. To ensure high reliability, the spacing between the dual rails must be highly consistent with the width of the battery pack. This results in complex positioning and high positioning accuracy required for the transfer device during clustering, leading to extremely low clustering efficiency and a high risk of errors. If an error occurs, the battery pack will collide hard with the securing structure, causing damage to the securing structure and, in severe cases, even damage to the battery pack. Summary of the Invention

[0004] The main objective of this invention is to provide a fixing component and an energy storage device having the same, so as to solve the problem that the fixing structure of the battery pack in the prior art affects the clustering efficiency of the battery pack and causes damage to the battery pack.

[0005] To achieve the above objectives, according to one aspect of the present invention, a fixing assembly is provided, disposed within an energy storage device for fixing a battery pack. The fixing assembly includes: a fixing structure having a limiting portion and a guiding portion, wherein there are at least two fixing structures disposed opposite to each other to surround and form an entry space and an opening communicating with the entry space, the opening for allowing the battery pack to move into the entry space, the limiting portion being located within the entry space for stopping and positioning the battery pack; wherein the guiding portion is located between the opening and the limiting portion, and the distance between the guiding portions of the at least two fixing structures gradually decreases along the direction from the opening to the limiting portion, the guiding portion for guiding the movement direction of the battery pack; and a limiting member disposed on the fixing structure and located within the entry space, the limiting member being located on the side of the guiding portion away from the limiting portion for stopping and positioning the battery pack.

[0006] Furthermore, the guide portion is a guide slope, and in the outer surface of the fixed structure within the cluster space, a limiting surface is formed on the outer surface of the guide slope near the limiting portion. The limiting surface is used for limiting and stopping the battery pack.

[0007] Furthermore, the fixing structure also has a support portion located below the cluster space, the support portion being used to support the battery pack; wherein, the fixing assembly also includes a friction-reducing member disposed on the support portion and located between the battery pack and the support portion, at least a portion of the friction-reducing member being made of insulating material.

[0008] Furthermore, the fixing structure includes a first plate-like structure, a first side plate, and a second side plate that are interconnected, with the first plate-like structure connected to the first side plate; wherein, at least two second side plates of the fixing structure surround each other to form an entry space, a portion of the second side plate is inclined toward the first side plate so as to form a guide slope through the plate surface of the portion of the second side plate and a limiting surface through the other portion of the second side plate, and the first plate-like structure forms a bearing portion.

[0009] Furthermore, the limiting part includes: a plate-shaped body disposed on the first plate-shaped structure, the plate-shaped body being used to limit and stop the battery pack; and a first buffer member disposed on the plate-shaped body and located between the plate-shaped body and the battery pack.

[0010] Furthermore, the limiting part also includes a limiting protrusion, which is disposed on the plate-shaped body. The limiting protrusion is used to extend into the mating recess of the battery pack and to limit and stop against the inner wall of the mating recess.

[0011] Furthermore, the limiting member has a first insertion portion, and the bearing portion is provided with a second insertion portion. One of the first insertion portion and the second insertion portion is a protrusion, and the other of the first insertion portion and the second insertion portion is a recess. The protrusion extends into the recess and engages with the recess.

[0012] Furthermore, the first insertion portion is a recess, the second insertion portion is a protrusion, and the limiting member includes a fifth plate-shaped structure, a sixth plate-shaped structure, a seventh plate-shaped structure, and an eighth plate-shaped structure connected in sequence. The sixth plate-shaped structure and the eighth plate-shaped structure are arranged opposite to each other, and the fifth plate-shaped structure is used to limit and stop the battery pack. The sixth plate-shaped structure, the seventh plate-shaped structure, and the eighth plate-shaped structure surround each other to form the first insertion portion, and the fifth plate-shaped structure is provided with a first through hole for the first fastener to pass through.

[0013] Furthermore, the limiting member also includes: a connecting plate disposed between the fifth plate structure and the sixth plate structure, the connecting plate being connected to at least one of the fifth plate structure and the sixth plate structure; the limiting member and the fixing structure being connected by passing a second fastener through the connecting plate and the fixing structure; and a second buffer disposed on the fifth plate structure, the second buffer being located between the fifth plate structure and the battery pack.

[0014] According to another aspect of the present invention, an energy storage device is provided, the energy storage device including a frame and a fixing component, the fixing component being disposed on the frame for fixing a battery pack; wherein the fixing component is the fixing component described above.

[0015] According to the technical solution of this invention, a fixing component is disposed within an energy storage device for fixing a battery pack. The fixing structure of the fixing component has a limiting part and a guiding part, and there are at least two of them. The at least two fixing structures are arranged opposite to each other to form an entry space and an opening communicating with the entry space. The opening is used to allow the battery pack to move into the entry space. The limiting part is located within the entry space to limit and stop the battery pack. The guiding part is located between the opening and the limiting part. Along the direction from the opening to the limiting part, the distance between the guiding parts of the at least two fixing structures gradually decreases. The guiding part is used to guide the movement direction of the battery pack. The limiting member is disposed on the fixing structure and located within the entry space. The limiting member is located on the side of the guiding part away from the limiting part to limit and stop the battery pack. In this way, during the battery pack clustering process, the guide section can guide the movement direction of the battery pack. Even if there is some error in the clustering angle or position, the battery pack can still successfully enter the cluster under the guidance of the guide section, initially reducing the positioning requirements during battery pack clustering. Furthermore, because the distance between the guide sections of at least two fixed structures gradually decreases, the size of the opening can be set larger, further reducing the positioning requirements during battery pack clustering. This simplifies the positioning process, reduces positioning accuracy, and allows the transfer device used to transport the battery pack to quickly perform the clustering operation, improving clustering efficiency and reducing the possibility of hard collisions between the battery pack and the fixed components. This solves the problem in existing technologies where the battery pack fixing structure affects the clustering efficiency and can cause damage to the battery pack. Simultaneously, the fixed structure and the limiting component form a stable fixing space, ensuring that the fixing function of the fixing components can be properly realized.

[0036] To address the problem that the existing battery pack fixing structure affects the clustering efficiency of the battery pack and can lead to battery pack damage, this application provides a fixing component and an energy storage device having the same.

[0037] like Figures 1 to 9 As shown, a fixing assembly is disposed within the energy storage device to fix the battery pack 1. The fixing assembly includes a fixing structure 10 and a limiting member 20. The fixing structure 10 has a limiting portion 11 and a guide portion 12. There are at least two fixing structures 10, which are arranged opposite to each other to form an entry space 13 and an opening 14 communicating with the entry space 13. The opening 14 is used for the battery pack 1 to move into the entry space 13. The limiting portion 11 is located within the entry space 13 to limit and stop the battery pack 1. The guide portion 12 is located between the opening 14 and the limiting portion 11. Along the direction from the opening 14 to the limiting portion 11, the distance between the guide portions 12 of the at least two fixing structures 10 gradually decreases. The guide portion 12 is used to guide the movement direction of the battery pack 1. The limiting member 20 is disposed on the fixing structure 10 and located within the entry space 13. The limiting member 20 is located on the side of the guide portion 12 away from the limiting portion 11 to limit and stop the battery pack 1.

[0038] Applying the technical solution of this embodiment, a fixing component is disposed within the energy storage device to fix the battery pack 1. The fixing structure 10 of the fixing component has a limiting part 11 and a guiding part 12, and there are at least two of them. The at least two fixing structures 10 are arranged opposite to each other to form an entry space 13 and an opening 14 communicating with the entry space 13. The opening 14 is used for the battery pack 1 to move into the entry space 13. The limiting part 11 is located within the entry space 13 to limit and stop the battery pack 1. The guiding part 12 is located between the opening 14 and the limiting part 11. Along the direction from the opening 14 to the limiting part 11, the distance between the guiding parts 12 of the at least two fixing structures 10 gradually decreases. The guiding part 12 is used to guide the movement direction of the battery pack 1. The limiting member 20 is disposed on the fixing structure 10 and located within the entry space 13. The limiting member 20 is located on the side of the guiding part 12 away from the limiting part 11 to limit and stop the battery pack 1. In this way, during the clustering process of battery pack 1, the guide part 12 can guide the movement direction of battery pack 1. That is, even if there is a certain error in the clustering angle or clustering position of battery pack 1, it can still be successfully clustered under the guidance of the guide part 12, which initially reduces the positioning requirements of battery pack 1 during clustering. Since the distance between the guide parts 12 of at least two fixed structures 10 gradually decreases, the size of the opening 14 can be set to be larger, further reducing the positioning requirements of battery pack 1 during clustering. This simplifies the positioning process, reduces the positioning accuracy, and enables the transfer device used to transfer battery pack 1 to quickly perform clustering operation, improving clustering efficiency and reducing the possibility of hard collision between battery pack 1 and fixed components. This solves the problem in the prior art that the battery pack fixing structure affects the clustering efficiency of the battery pack and causes damage to the battery pack. At the same time, a stable fixing space is formed between the fixing structure 10 and the limiting member 20 to ensure that the fixing function of the fixing component can be realized normally.

[0039] In this embodiment, there are two fixing structures 10, which are arranged opposite to each other.

[0040] It should be noted that the number of fixed structures 10 is not limited to this and can be adjusted according to working conditions and usage requirements.

[0041] In this embodiment, the battery pack 1 has a cuboid structure. After the battery pack 1 enters the clustering space 13, the inner wall of the clustering space 13 (the side surfaces of the two fixing structures 10 arranged opposite each other) can limit and stop the battery pack 1 in the width direction, while the limiting part 11 and the limiting member 20 can limit and stop the battery pack 1 in the length direction, so as to fix the battery pack 1.

[0042] In this embodiment, the limiting member 20 and the fixing structure 10 are actually designed separately. That is, the limiting member 20 is set on the fixing structure 10 after the battery pack 1 is inserted into the cluster, so as to limit and fix the battery pack 1.

[0043] like Figure 3 and Figure 4 As shown, the guide portion 12 is a guide slope. On the outer surface of the fixing structure 10 within the clustering space 13, a limiting surface 15 is formed on the side of the guide slope closest to the limiting portion 11. The limiting surface 15 serves as a limiting stop for the battery pack 1. Thus, after the battery pack 1 is guided by the guide slope and clustered, its outer surface can be stopped by the limiting surface 15, thereby limiting and fixing the battery pack 1 in a direction perpendicular to its movement direction (the width direction of the battery pack 1), thereby improving the fixing reliability of the fixing assembly. Simultaneously, the above configuration also simplifies the structure of the guide portion 12, making it easier to manufacture and implement.

[0044] In this embodiment, the distance between the limiting surfaces 15 of the two fixing structures 10 is basically the same as the width of the battery pack 1, so as to ensure that the fixing components have high fixing reliability for the battery pack 1.

[0045] Specifically, as the distance between the guide portions 12 (guide ramps) of the two fixed structures 10 gradually decreases along the direction from the opening 14 to the limiting portion 11, the distance between the outer surfaces of the two fixed structures 10 on the side of the guide ramp away from the limiting portion 11 is greater than the distance between the two limiting surfaces 15. That is, the width of the opening 14 is greater than the width of the battery pack 1, so that the battery pack 1 can enter the opening 14 more easily, greatly reducing the positioning requirements when the battery pack 1 enters the cluster.

[0046] like Figure 3 and Figure 4 As shown, the fixing structure 10 also has a support portion 16 located below the clustering space 13, which supports the battery pack 1. The fixing assembly also includes a friction-reducing member 30, which is disposed on the support portion 16 and located between the battery pack 1 and the support portion 16. At least a portion of the friction-reducing member 30 is made of insulating material. In this way, the friction-reducing member 30 can prevent damage to the paint surface of the support portion 16 during the clustering process of the battery pack 1, thereby reducing its replacement frequency and extending the service life of the fixing assembly. Simultaneously, the friction-reducing member 30, made of insulating material, also provides insulation and prevents leakage.

[0047] In this embodiment, the wear-reducing component 30 is a pad-shaped structure.

[0048] Specifically, the bottom of the battery pack 1 is provided with a support protrusion 102. When the battery pack 1 is inserted into the cluster, the support protrusion 102 can reduce the contact area between the battery pack 1 and the wear-reducing part 30, thereby reducing the resistance when the battery pack 1 is inserted into the cluster and thus improving the insertion efficiency of the battery pack 1.

[0049] In this embodiment, the support protrusion 102 at the bottom of the battery pack 1 is composed of ribs.

[0050] like Figure 4 As shown, the fixing structure 10 includes a first plate-like structure 171, a first side plate 172, and a second side plate 174 connected in sequence, with the first plate-like structure 171 connected to the first side plate 172. At least two of the second side plates 174 of the fixing structure 10 surround each other to form an infill space 13. A portion of the second side plate 174 is inclined towards the first side plate 172, forming a guide slope on the surface of this portion of the second side plate 174 and a limiting surface 15 on another portion of the second side plate 174. The first plate-like structure 171 forms a bearing portion 16. Thus, the fixing structure 10 is entirely made of common sheet metal, which not only simplifies the structure of the fixing structure 10 but also reduces its processing cost.

[0051] In this embodiment, the length of the first side plate 172 is less than the length of the second side plate 174, so that an opening 14 is formed through the ends of the two first side plates 172.

[0052] In this embodiment, a second plate-shaped structure 173 for connecting the first side plate 172 and the second side plate 174 is also provided, so that the distance between the first side plates 172 (the size of the opening 14) is greater than the distance between the two second side plates 174 (i.e. the width of the battery pack 1) through the second plate-shaped structure 173.

[0053] like Figure 4 As shown, the limiting part 11 includes a plate-shaped main body 111 and a first buffer member 112. The plate-shaped main body 111 is disposed on the first plate-shaped structure 171 and is used to limit and stop the battery pack 1. The first buffer member 112 is disposed on the plate-shaped main body 111 and is located between the plate-shaped main body 111 and the battery pack 1. In this way, after the battery pack 1 enters the cluster, the first buffer member 112 buffers the battery pack 1, which can reduce the impact force on the plate-shaped main body 111 when the battery pack 1 enters the cluster and absorb the impact vibration. This not only improves the structural stability of the fixing assembly, but also ensures that the battery pack 1 will not be damaged during the clustering process.

[0054] In this embodiment, the first buffer 112 is made of an elastic material, such as rubber or silicone.

[0055] Specifically, the plate-shaped main body 111 is disposed on the first plate-shaped structure 171 and located on the side of the guide portion 12 away from the limiting member 20.

[0056] like Figure 4 As shown, the limiting part 11 also includes a limiting protrusion 113, which is disposed on the plate-shaped main body 111. The limiting protrusion 113 is used to extend into the mating recess 101 of the battery pack 1 and to limit and stop against the inner wall of the mating recess 101. In this way, after the battery pack 1 is installed, the limiting protrusion 113 and the mating recess 101 cooperate to restrict the movement of the battery pack 1, thereby further improving the fixation stability of the battery pack 1.

[0057] In this embodiment, the limiting protrusion 113 is shaped like a snake's head.

[0058] Specifically, the limiting protrusion 113 is located on the side of the plate-shaped body 111 facing the cluster space 13.

[0059] like Figure 4 and Figure 5 As shown, the limiting member 20 has a first insertion portion 21, and the supporting portion 16 is provided with a second insertion portion 161. One of the first insertion portion 21 and the second insertion portion 161 is a protrusion, and the other of the first insertion portion 21 and the second insertion portion 161 is a recess. The protrusion extends into the recess and engages with the recess. In this way, after the battery pack 1 is installed and the limiting member 20 is installed, the engagement of the first insertion portion 21 and the second insertion portion 161 can prevent the limiting member 20 from vibrating during long-term use, which could lead to loosening of fasteners and detachment of the limiting member 20, thereby improving the assembly stability of the limiting member 20. At the same time, the above-mentioned configuration makes the structure of the first insertion portion 21 and the second insertion portion 161 more flexible and diverse to adapt to different working conditions and usage requirements, and also improves the processing flexibility of the workers.

[0060] In this embodiment, the first insertion portion 21 is a recess, the second insertion portion 161 is a protrusion, and the limiting member 20 includes a fifth plate-shaped structure 22, a sixth plate-shaped structure 23, a seventh plate-shaped structure 24, and an eighth plate-shaped structure 25 connected in sequence. The sixth plate-shaped structure 23 and the eighth plate-shaped structure 25 are disposed opposite to each other, and the fifth plate-shaped structure 22 is used to limit and stop the battery pack 1. The first insertion portion 21 is formed by the sixth plate-shaped structure 23, the seventh plate-shaped structure 24, and the eighth plate-shaped structure 25 surrounding each other, and the fifth plate-shaped structure 22 is provided with a first through hole 221 for the first fastener 40 to pass through. In this way, the above-mentioned arrangement allows the limiting member 20 to be made of common sheet metal, thereby reducing the processing difficulty and processing cost of the limiting member 20; on the other hand, it makes the formation of the first insertion portion 21 simpler.

[0061] In this embodiment, the first fastener 40 passes through the first through hole 221 and is fastened to the battery pack 1, which further improves the fixing reliability of the fixing component.

[0062] Optionally, the first fastener 40 is a bolt.

[0063] In this embodiment, the seventh plate structure 24 is an arc-shaped plate, and the sixth plate structure 23, the seventh plate structure 24 and the eighth plate structure 25 surround each other to form a "U"-shaped recess.

[0064] In this embodiment, the second insertion portion 161 is formed from the end of the first plate-shaped structure 171 away from the limiting portion 11.

[0065] Specifically, during the handling of the energy storage device, the internal structure will inevitably vibrate due to the handling action. The vibration can be offset by the insertion and engagement between the limiting member 20 and the first plate structure 171, thus avoiding the problem of loose bolts.

[0066] Specifically, when assembling the limiting component 20, the worker needs to insert the end of the first plate-shaped structure 171 into the "U"-shaped recess. This not only provides initial fixation for the limiting component 20 but also reduces the difficulty of subsequent assembly. Simultaneously, after the limiting component 20 is assembled, the limiting stop between the first plate-shaped structure 171 and the inner wall of the "U"-shaped recess helps alleviate vibration issues and prevents fasteners from loosening.

[0067] Specifically, the fifth plate structure 22 and the sixth plate structure 23 are arranged perpendicularly to each other, and the eighth plate structure 25 is located below the sixth plate structure 23. The eighth plate structure 25 is connected to the sixth plate structure 23 through the seventh plate structure 24.

[0068] like Figure 1 As shown, the limiting member 20 also includes a connecting plate 26 and a second buffer 27. The connecting plate 26 is disposed between the fifth plate-shaped structure 22 and the sixth plate-shaped structure 23, and is connected to at least one of the fifth plate-shaped structure 22 and the sixth plate-shaped structure 23. The limiting member 20 and the fixed structure 10 are connected by passing a second fastener 50 through the connecting plate 26 and the fixed structure 10. The second buffer 27 is disposed on the fifth plate-shaped structure 22 and is located between the fifth plate-shaped structure 22 and the battery pack 1. In this way, the above-mentioned arrangement of the connecting plate 26 strengthens the overall structure of the limiting member 20, thereby extending the service life of the limiting member 20 and increasing the connection area between the limiting member 20 and the fixed structure 10, further improving the fixing stability of the limiting member 20.

[0069] Optionally, the second fastener 50 is a bolt.

[0070] Optionally, the second buffer 27 is made of an elastic material, such as rubber or silicone.

[0071] This application also provides an energy storage device (not shown), which includes a frame and a fixing component. The fixing component is disposed on the frame for fixing a battery pack 1. The fixing component is the aforementioned fixing component.

[0072] As can be seen from the above description, the embodiments of the present invention achieve the following technical effects:

[0073] A fixing assembly is installed within the energy storage device to secure the battery pack. The fixing structure of the fixing assembly has at least two limiting and guiding portions. These at least two fixing structures are arranged opposite each other to form an entry space and an opening communicating with the entry space. The opening allows the battery pack to move into the entry space. The limiting portion is located within the entry space to stop and restrain the battery pack. The guiding portion is located between the opening and the limiting portion. Along the direction from the opening to the limiting portion, the distance between the guiding portions of the at least two fixing structures gradually decreases. The guiding portion guides the movement direction of the battery pack. A limiting member is installed on the fixing structure and located within the entry space. The limiting member is located on the side of the guiding portion away from the limiting portion to stop and restrain the battery pack. In this way, during the battery pack clustering process, the guide section can guide the movement direction of the battery pack. Even if there is some error in the clustering angle or position, the battery pack can still successfully enter the cluster under the guidance of the guide section, initially reducing the positioning requirements during battery pack clustering. Furthermore, because the distance between the guide sections of at least two fixed structures gradually decreases, the size of the opening can be set larger, further reducing the positioning requirements during battery pack clustering. This simplifies the positioning process, reduces positioning accuracy, and allows the transfer device used to transport the battery pack to quickly perform the clustering operation, improving clustering efficiency and reducing the possibility of hard collisions between the battery pack and the fixed components. This solves the problem in existing technologies where the battery pack fixing structure affects the clustering efficiency and can cause damage to the battery pack. Simultaneously, the fixed structure and the limiting component form a stable fixing space, ensuring that the fixing function of the fixing components can be properly realized.
