Description

Technical Field

[0001] This utility model relates to the field of energy storage equipment technology, and in particular to an energy storage container battery pack.

[0002] Vibration testing device. Background Technology

[0003] An energy storage container is a device that stores electrical energy and releases it when needed. It combines energy storage with logistics transportation, allowing electricity to be stored and transmitted in different locations, thus enabling more flexible and efficient use of electrical energy. Energy storage containers offer excellent convenience, reliability, economy, and safety, and are therefore widely used in many fields such as power, communications, and transportation.

[0004] Energy storage containers typically consist of a shell, battery compartment, battery system, cooling system, and control system. The battery compartment houses the battery packs, which are bolted into the compartment and serve as the energy storage medium for the container. During long-distance transportation to the site, these battery pack bolts may come loose, adversely affecting the container's usability. Therefore, vibration testing of the battery packs is required before the container leaves the factory to ensure that the bolts securing the battery packs to the battery compartment do not loosen during transport.

[0005] Existing vibration testing devices for battery packs in energy storage containers typically involve directly bolting the battery packs to a testing platform. This method fails to simulate the real-world condition of battery packs being bolted into the battery compartment, and therefore cannot fully simulate the actual transportation environment. Consequently, even battery packs tested by vibration testing devices cannot guarantee that the bolts securing them to the battery compartment will not come loose during transport, posing a potential safety hazard during the use of the energy storage container. Utility Model Content

[0006] The purpose of this invention is to address the shortcomings of the prior art by providing a vibration testing device for battery packs in energy storage containers. This device can simulate the vibrations generated by the battery packs in real transportation environments, thereby making the vibration testing of the battery packs more accurate. This ensures that the bolts used to fix the battery packs in the battery compartment will not come loose during the transportation of the energy storage container, thus guaranteeing the performance of the energy storage container.

[0007] This utility model proposes a vibration testing device for an energy storage container battery pack, including a testing platform and a testing bracket fixedly installed on the testing platform. The testing bracket has a receiving cavity, in which the battery pack is disposed and fixedly connected to the testing bracket. The testing platform is used to perform vibration testing on the battery pack in the receiving cavity.

[0008] Furthermore, the test bracket includes a top bracket, a bottom bracket, and two side brackets connecting the top bracket and the bottom bracket, wherein the top bracket, the bottom bracket, and the two side brackets enclose the receiving cavity.

[0009] Furthermore, the test bracket also includes two support brackets respectively disposed inside the two side brackets, the two support brackets being fixedly connected to the two side brackets respectively, and the battery pack being fixedly connected to the two support brackets so that the two support brackets support the battery pack.

[0010] Furthermore, the inner side of the side bracket is provided with a rivet nut, the support bracket is provided with a first through hole, and the vibration testing device further includes a first bolt that passes through the first through hole and is screwed to the rivet nut.

[0011] Furthermore, the support bracket is provided with a strip-shaped hole, the battery pack is provided with a first threaded hole, and the vibration testing device also includes a second bolt that passes through the strip-shaped hole and is screwed into the first threaded hole.

[0012] Furthermore, the top support includes a top frame that surrounds the perimeter, and at least two top beams that are intersected within the top frame, with both ends of the top beams fixedly connected to the top frame.

[0013] Furthermore, a lifting ring is provided on the top frame for hoisting the test bracket.

[0014] Furthermore, the bottom support includes a bottom frame that surrounds the perimeter, and a plurality of bottom crossbeams that are arranged in parallel and spaced apart in the bottom frame, with both ends of the bottom crossbeams fixedly connected to the bottom frame.

[0015] Furthermore, the side support includes a plurality of side vertical beams extending in a vertical direction and a plurality of side horizontal beams extending in a horizontal direction.

[0033] To make the objectives, technical solutions, and advantages of the embodiments of this utility model clearer, the technical solutions of the embodiments of this utility model will be clearly and completely described below with reference to the accompanying drawings. All other embodiments obtained by those skilled in the art based on the embodiments of this utility model without creative effort are within the scope of protection of this utility model.

[0034] Please see Figures 1 to 7 A vibration testing device for an energy storage container battery pack according to an embodiment of the present invention includes a test platform 1, a test bracket 2 fixedly installed on the test platform 1, a receiving cavity 25 provided in the test bracket 2, a battery pack 3 disposed in the receiving cavity 25 and fixedly connected to the test bracket 2, and the test platform 1 is used to perform vibration testing on the battery pack 3 in the receiving cavity 25.

[0035] In this application, the vibration testing device includes a test platform 1 and a test bracket 2, with the test bracket 2 fixedly mounted on the test platform 1. A receiving cavity 25 is provided in the test bracket 2, and the battery pack 3 is placed in the receiving cavity 25 and fixedly connected to the test bracket 2, thereby simulating the actual state of the battery pack 3 fixed in the battery compartment of an energy storage container.

[0036] Existing energy storage containers typically use bolts to fix the battery pack 3 in the battery compartment. Therefore, in this application, the battery pack 3 can be fixedly connected to the test bracket 2 using bolts. Then, the battery pack 3 in the test bracket 2 is subjected to vibration testing through the test platform 1 to simulate the vibration generated by the battery pack 3 in a real transportation environment. This makes the vibration test of the battery pack 3 more accurate, ensuring that the bolts used to fix the battery pack 3 in the battery compartment will not fall off during the transportation of the energy storage container, thereby ensuring the performance of the energy storage container.

[0037] In this embodiment, the test bracket 2 includes a top bracket 21, a bottom bracket 22 and two side brackets 23. The two side brackets 23 are disposed between the top bracket 21 and the bottom bracket 22 to connect the top bracket 21 and the bottom bracket 22, so that the top bracket 21, the bottom bracket 22 and the two side brackets 23 enclose and form a receiving cavity 25.

[0038] By loading the battery pack 3 into the accommodating cavity 25, the actual spatial state of the battery pack 3 loaded in the battery compartment of the energy storage container is simulated, making the vibration test of the battery pack 3 more accurate. This ensures that the bolts used to fix the battery pack 3 in the battery compartment will not come loose during the transportation of the energy storage container, thereby ensuring the performance of the energy storage container.

[0039] Furthermore, in this embodiment, the test bracket 2 also includes two support brackets 24, which are respectively disposed inside the two side brackets 23 and fixedly connected to the two side brackets 23. The battery pack 3 is fixedly connected to the two support brackets 24 so that the two support brackets 24 support the battery pack 3.

[0040] When conducting vibration tests on battery pack 3, firstly, fix the two support brackets 24 to the two side brackets 23 respectively, fix the two support brackets 24 to the inside of the two side brackets 23 respectively, then place the battery pack 3 on the two support brackets 24 so that the two support brackets 24 support the battery pack 3, and then fix the battery pack 3 to the two support brackets 24 to simulate the real space state of the battery pack 3 loaded in the battery compartment of the energy storage container.

[0041] Finally, the test bracket 2 is placed on the test platform 1 and fixedly connected to the test platform 1. The test platform 1 is then used to conduct a vibration test on the battery pack 3 in the test bracket 2, simulating the vibration generated by the battery pack 3 in a real transportation environment. This makes the vibration test of the battery pack 3 more accurate, ensuring that the bolts used to fix the battery pack 3 in the battery compartment will not fall off during the transportation of the energy storage container, thereby ensuring the performance of the energy storage container.

[0042] Specifically, in this embodiment, the vibration testing device also includes a first bolt, a rivet nut 233 is provided on the inner side of the side bracket 23, and a first through hole 241 is provided on the support bracket 24. After one end of the first bolt passes through the first through hole 241 on the support bracket 24, it is screwed to the rivet nut 233 on the inner side of the side bracket 23, thereby fixing the support bracket 24 to the side bracket 23 and realizing the fixed installation of the support bracket 24 on the inner side of the side bracket 23.

[0043] Specifically, in this embodiment, the vibration testing device also includes a second bolt, a strip hole 242 on the support bracket 24, and a first threaded hole 31 on the battery pack 3. After one end of the second bolt passes through the strip hole 242 on the support bracket 24, it is screwed into the first threaded hole 31 on the battery pack 3, thereby fixing the battery pack 3 to the support bracket 24. This simulates the real spatial state of the battery pack 3 when it is loaded in the accommodating cavity 25 and placed in the battery compartment of the energy storage container.

[0044] In this application, the battery pack 3 is supported by two support brackets 24. When the two support brackets 24 are fixedly installed on the inner side of the two side brackets 23, the distance between the two support brackets 24 is fixed. Therefore, a strip hole 242 is provided on the support bracket 24 so that battery packs 3 of different widths can be placed on the two support brackets 24 and fixedly connected to the two support brackets 24. This makes the vibration testing device applicable to battery packs 3 of different sizes, thereby making the application range of the vibration testing device wider, the practicality stronger, and the testing cost lower.

[0045] In this embodiment, the top support 21 includes a top frame 211 and at least two top crossbeams 212. The top frame 211 surrounds the entire perimeter, and the at least two top crossbeams 212 are intersecting within the top frame 211. Both ends of at least the top crossbeams 212 are fixedly connected to the top frame 211, thereby ensuring the structural strength of the top support 21, that is, ensuring the structural strength of the test support 2. This enables the test platform 1 to perform vibration tests on the battery pack 3 in the test support 2, simulating the vibration generated by the battery pack 3 in a real transportation environment.

[0046] As mentioned in the previous embodiment: when conducting vibration testing of battery pack 3, firstly, two support brackets 24 are fixedly installed on the inner side of two side brackets 23 respectively, then the battery pack 3 is placed on the two support brackets 24 and fixedly connected to the two support brackets 24, and finally the test bracket 2 is placed on the test platform 1.

[0047] Specifically, in this embodiment, a lifting ring 213 is provided on the top frame 211. After the battery pack 3 is loaded into the accommodating cavity 25 of the test bracket 2, the test bracket 2 and the battery pack 3 are hoisted onto the test platform 1 as a whole by the lifting ring 213. Thus, the battery pack 3 in the accommodating cavity 25 of the test bracket 2 is subjected to vibration test by the test platform 1, making the use of this vibration test device simpler, more convenient and easier to implement.

[0048] In this embodiment, the bottom support 22 includes a bottom frame 221 and multiple bottom crossbeams 222. The bottom frame 221 surrounds the perimeter, and the multiple bottom crossbeams 222 are arranged in parallel and spaced apart in the bottom frame 221. The two ends of the multiple bottom crossbeams 222 are fixedly connected to the bottom frame 221, thereby ensuring the structural strength of the bottom support 22, that is, ensuring the structural strength of the test support 2. This enables the test platform 1 to perform vibration tests on the battery pack 3 in the test support 2, simulating the vibration generated by the battery pack 3 in a real transportation environment.

[0049] In this embodiment, the side support 23 includes multiple side vertical beams 231 and multiple side horizontal beams 232. The multiple side vertical beams 231 extend vertically, and the multiple side horizontal beams 232 extend horizontally. The top of the multiple side vertical beams 231 is connected to the top support 21, and the bottom is connected to the bottom support 22, so that the two side supports 23 connect the top support 21 and the bottom support 22, and the top support 21, the bottom support 22 and the two side supports 23 enclose and form a receiving cavity 25.

[0050] The side crossbeam 232 connects two adjacent vertical beams, thereby ensuring the structural strength of the side support 23, that is, ensuring the structural strength of the test support 2, so that the test platform 1 can simulate the vibration generated by the battery pack 3 in the test support 2 in the real transportation environment when conducting vibration tests on the battery pack 3 in the test support 2.

[0051] Specifically, in this embodiment, the vibration testing device further includes multiple third bolts, multiple second through holes 223 are provided on the bottom frame 221, and multiple second threaded holes 11 are provided on the test platform 1 in an array. After the test bracket 2 is hoisted onto the test platform 1 by the lifting ring 213, the multiple third bolts pass through the multiple second through holes 223 on the bottom frame 221 and are screwed into the corresponding second threaded holes 11 on the test platform 1, thereby achieving a fixed connection between the test bracket 2 and the test platform 1.

[0052] Then, the battery pack 3 in the test bracket 2 is subjected to vibration test through the test platform 1 to simulate the vibration generated by the battery pack 3 in the real transportation environment, so as to make the vibration test of the battery pack 3 more accurate, so as to ensure that the bolts used to fix the battery pack 3 in the battery compartment will not fall off during the transportation of the energy storage container, thereby ensuring the performance of the energy storage container.

[0053] The reason for setting multiple arrayed second threaded holes 11 on the test platform 1 is to enable the test bracket 2 to be fixedly connected to the test platform 1 when it is hoisted to any position on the test platform 1 by the lifting ring 213, thereby making the use of this test device simpler, more convenient, easier to implement, and more practical.
