[0036] In order to solve the problem that the battery pack fixing structure in the prior art affects the cluster entry efficiency of the battery pack and causes damage to the battery pack, a fixing assembly and an energy storage equipment with the same are provided.

[0037] As shown in Figures 1 to 9 The fixing assembly is arranged in the energy storage equipment to fix the battery pack 1, and the fixing assembly comprises a fixing structure 10 and a limiting piece 20; the fixing structure 10 has a limiting portion 11 and a guide portion 12; there are at least two fixing structures 10, and the at least two fixing structures 10 are oppositely arranged to surround a cluster entry space 13 and an opening 14 communicating with the cluster entry space 13; the opening 14 is used for allowing the battery pack 1 to move into the cluster entry space 13; the limiting portion 11 is located in the cluster entry space 13 and is used for limiting and stopping the battery pack 1. The guide portion 12 is located between the opening 14 and the limiting portion 11 and gradually decreases in distance between the guide portions 12 of the at least two fixing structures 10 in the direction from the opening 14 to the limiting portion 11; the guide portion 12 is used for guiding the movement direction of the battery pack 1. The limiting piece 20 is arranged on the fixing structure 10 and located in the cluster entry space 13; the limiting piece 20 is located on the side of the guide portion 12 away from the limiting portion 11 and is used for limiting and stopping the battery pack 1.

[0038] The technical scheme is applied, the fixing assembly is arranged in the energy storage device to fix the battery pack 1, the fixing structure 10 of the fixing assembly is provided with at least two limiting portions 11 and guiding portions 12, the at least two fixing structures 10 are oppositely arranged to form a clustering space 13 and an opening 14 communicating with the clustering space 13, the opening 14 is used for moving the battery pack 1 into the clustering space 13, the limiting portion 11 is located in the clustering space 13 and is used for limiting and stopping the battery pack 1. The guiding portion 12 is located between the opening 14 and the limiting portion 11, the distance between the guiding portions 12 of the at least two fixing structures 10 gradually decreases in the direction from the opening 14 to the limiting portion 11, the guiding portion 12 is used for guiding the movement direction of the battery pack 1, and the limiting piece 20 is arranged on the fixing structure 10 and located in the clustering space 13. The limiting piece 20 is located on the side of the guiding portion 12 away from the limiting portion 11 and is used for limiting and stopping the battery pack 1. In this way, during the clustering of the battery pack 1, the guiding portion 12 can guide the movement direction of the battery pack 1, that is, even if the clustering angle or the clustering position of the battery pack 1 has a certain error, the battery pack 1 can successfully cluster under the guidance of the guiding portion 12, and the positioning requirement of the battery pack 1 during clustering is preliminarily reduced. The size of the opening 14 can be set larger due to the gradually decreasing distance between the guiding portions 12 of the at least two fixing structures 10, and the positioning requirement of the battery pack 1 during clustering is further reduced, thereby simplifying the positioning process, reducing the positioning accuracy, enabling the transfer device for transferring the battery pack 1 to quickly perform the clustering operation, improving the clustering efficiency, and reducing the possibility of hard collision between the battery pack 1 and the fixing assembly. Thus, the problem that the battery pack fixing structure in the prior art affects the clustering efficiency of the battery pack and causes damage to the battery pack is solved. Meanwhile, a stable fixing space is formed between the fixing structure 10 and the limiting piece 20, so that the fixing function of the fixing assembly can be normally realized.

[0039] In the embodiment, the fixing structure 10 is two, and the two fixing structures 10 are oppositely arranged.

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

[0041] In the embodiment, the battery pack 1 is a cuboid structure, after the battery pack 1 enters the clustering space 13, the inner wall (the side surface of the oppositely arranged two fixing structures 10) of the clustering space 13 can limit and stop the battery pack 1 in the width direction of the battery pack 1, and the limiting portion 11 and the limiting piece 20 can limit and stop the battery pack 1 in the length direction of the battery pack 1, so as to fix the battery pack 1.

[0042] In the embodiment, the limiting member 20 and the fixing structure 10 are actually designed in a split type, that is, when the battery pack 1 is inserted into the cluster, the limiting member 20 is arranged on the fixing structure 10 to limit and fix the battery pack 1.

[0043] As shown in Figure 3 and Figure 4 , the guide part 12 is a guide slope, and the outer surface of the fixing structure 10 located on the side of the guide slope close to the limiting part 11 forms a limiting surface 15 in the outer surface of the fixing structure 10 in the insertion space 13, and the limiting surface 15 is used for limiting and stopping the battery pack 1. In this way, after the battery pack 1 is guided by the guide slope and inserted into the cluster, the outer surface of the battery pack 1 can be limited and stopped by the limiting surface 15, thereby limiting and fixing the battery pack 1 in the direction perpendicular to the movement direction (the width direction of the battery pack 1), thereby improving the fixing reliability of the fixing assembly. At the same time, the above-mentioned arrangement also makes the structure of the guide part 12 more simple, easy to process and realize.

[0044] In the 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 assembly has high fixing reliability for the battery pack 1.

[0045] Specifically, since the distance between the guide parts 12 (guide slopes) of the two fixing structures 10 gradually decreases in the direction from the opening 14 to the limiting part 11, the distance between the outer surfaces of the two fixing structures 10 located on the side of the guide slope away from the limiting part 11 is greater than the distance between the two limiting surfaces 15, that is, the width size of the opening 14 is greater than the width size of the battery pack 1, so that the battery pack 1 can more easily enter the opening 14, greatly reducing the positioning requirements when the battery pack 1 is inserted into the cluster.

[0046] As shown in Figure 3 and Figure 4 , the fixing structure 10 also has a bearing part 16 located below the insertion space 13, and the bearing part 16 is used for bearing the battery pack 1. The fixing assembly further comprises an anti-friction member 30 arranged on the bearing part 16 and located between the battery pack 1 and the bearing part 16, and at least part of the anti-friction member 30 is made of insulating material. In this way, the anti-friction member 30 can prevent the paint surface of the bearing part 16 from being damaged during the insertion of the battery pack 1 into the cluster, thereby reducing the replacement frequency and prolonging the service life of the fixing assembly. At the same time, the anti-friction member 30 made of insulating material can also play the functions of insulation isolation and leakage prevention.

[0047] In the embodiment, the anti-friction member 30 is a pad-shaped structure.

[0048] Specifically, the bottom of the battery pack 1 is provided with a support protrusion 102, which can reduce the contact area between the battery pack 1 and the wear-reducing piece 30 when the battery pack 1 is clustered, thereby reducing the resistance when the battery pack 1 is clustered, and thereby improving the clustering efficiency of the battery pack 1.

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

[0050] As shown in Figure 4 The fixing structure 10 includes a first plate-shaped structure 171, a first side plate 172 and a second side plate 174 connected in sequence, and the first plate-shaped structure 171 is connected with the first side plate 172. Among them, the second side plates 174 of at least two fixing structures 10 surround the clustering space 13, and a part of the second side plate 174 is inclinedly arranged towards the first side plate 172 to form a guide inclined surface through the plate surface of the part of the second side plate 174 and a limiting surface 15 through another part of the second side plate 174, and the first plate-shaped structure 171 forms a bearing part 16. In this way, the fixing structure 10 is made of common plate material as a whole, which not only makes the structure of the fixing structure 10 simpler, but also reduces the processing cost of the fixing structure 10.

[0051] In this embodiment, the length of the first side plate 172 is smaller than the length of the second side plate 174, so as to form the opening 14 through the end portions of the two first side plates 172.

[0052] In this embodiment, a second plate-shaped structure 173 is further arranged between the first side plate 172 and the second side plate 174 for connecting the two, so as to make the distance between the first side plates 172 (the size of the opening 14) larger 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] As shown in Figure 4 The limiting part 11 includes a plate-shaped main body 111 and a first buffer 112, the plate-shaped main body 111 is arranged on the first plate-shaped structure 171 and is used for limiting and stopping the battery pack 1. The first buffer 112 is arranged 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 is clustered, the battery pack 1 is buffered by the first buffer 112, which can reduce the impact force of the battery pack 1 on the plate-shaped main body 111 when the battery pack 1 is clustered, and absorb the impact vibration, thereby not only improving the structural stability of the fixing assembly, but also ensuring that the battery pack 1 will not be damaged during the clustering process.

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

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

[0056] As shown in Figure 4 , the limiting portion 11 further comprises a limiting protrusion 113, which is arranged on the plate-shaped body 111 and used for extending into the matching recess 101 of the battery pack 1 and limiting and stopping with the inner wall of the matching recess 101. In this way, after the battery pack 1 is installed into the cluster, the limiting protrusion 113 cooperates with the matching recess 101 to limit the movement of the battery pack 1, further improving the fixing stability of the battery pack 1.

[0057] In this embodiment, the limiting protrusion 113 is a snake head-shaped structure.

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

[0059] As shown in Figure 4 and Figure 5 , the limiting piece 20 has a first plug-in portion 21, and the bearing portion 16 is provided with a second plug-in portion 161, one of the first plug-in portion 21 and the second plug-in portion 161 is a protrusion, and the other is a recess, the protrusion extends into the recess and is plug-in cooperated with the recess. In this way, after the battery pack 1 is installed into the cluster and the limiting piece 20 is installed, the plug-in cooperation of the first plug-in portion 21 and the second plug-in portion 161 can avoid the loosening of the fastener and the falling off of the limiting piece 20 due to the vibration of the limiting piece 20 in the long-term use, thereby improving the assembly stability of the limiting piece 20. At the same time, the above-mentioned arrangement makes the structure of the first plug-in portion 21 and the second plug-in portion 161 more flexible and diverse to adapt to different working conditions and use requirements, and also improves the processing flexibility of the workers.

[0060] In this embodiment, the first plug-in portion 21 is a recess, the second plug-in portion 161 is a protrusion, and the limiting piece 20 comprises 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 arranged opposite to each other, and the fifth plate-shaped structure 22 is used for limiting and stopping with the battery pack 1. Among them, the first plug-in portion 21 is formed around the sixth plate-shaped structure 23, the seventh plate-shaped structure 24 and the eighth plate-shaped structure 25, 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 makes the limiting piece 20 as a whole composed of common plate materials, thereby reducing the processing difficulty and processing cost of the limiting piece 20; on the other hand, it makes the forming method of the first plug-in portion 21 more simple.

[0061] In the embodiment, the first fastener 40 is fastened on the battery pack 1 after passing through the first through hole 221, further improving the fixing reliability of the fixing assembly.

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

[0063] In the embodiment, the seventh plate-shaped structure 24 is an arc-shaped plate, and a "U"-shaped recess is formed around the sixth plate-shaped structure 23, the seventh plate-shaped structure 24, and the eighth plate-shaped structure 25.

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

[0065] Specifically, during the carrying of the energy storage device, the internal structure of the energy storage device will inevitably vibrate due to the carrying operation. The insertion and fitting between the limiting part 20 and the first plate-shaped structure 171 can offset the vibration, and the problem of bolt loosening can be avoided.

[0066] Specifically, when the staff assembles the limiting part 20, the end of the first plate-shaped structure 171 is inserted into the "U"-shaped recess, thereby preliminarily fixing the limiting part 20 and reducing the difficulty of subsequent assembly of the staff. At the same time, after the limiting part 20 is assembled, the vibration problem of the limiting part 20 can be alleviated by the limiting and stopping between the first plate-shaped structure 171 and the inner wall of the "U"-shaped recess, and the problem of fastener loosening can be avoided.

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

[0068] As shown in Figure 1 The limiting part 20 further includes a connecting plate 26 and a second buffer 27. The connecting plate 26 is arranged between the fifth plate-shaped structure 22 and the sixth plate-shaped structure 23, and the connecting plate 26 is connected with at least one of the fifth plate-shaped structure 22 and the sixth plate-shaped structure 23. The second fastener 50 is inserted through the connecting plate 26 and the fixing structure 10 to connect the limiting part 20 and the fixing structure 10. The second buffer 27 is arranged on the fifth plate-shaped structure 22, and the second buffer 27 is located between the fifth plate-shaped structure 22 and the battery pack 1. In this way, the above arrangement of the connecting plate 26 strengthens the overall structure of the limiting part 20, prolongs the service life of the limiting part 20, increases the connection area between the limiting part 20 and the fixing structure 10, and further improves the fixing stability of the limiting part 20.

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

[0070] Optionally, the second buffer member 27 is made of an elastic material, such as a rubber member, a silica gel member, etc.

[0071] The application further provides a storage energy device (not shown), which comprises a frame and a fixing assembly arranged on the frame for fixing the battery pack 1.
