Description

Technical Field

[0001] This utility model relates to the field of battery cluster frame technology, specifically a shock-absorbing structure for a battery cluster frame used in energy storage boxes. Background Technology

[0002] Energy storage batteries play multiple roles in power systems, including storage, regulation, and backup, enhancing grid stability, energy efficiency, and the integration of renewable energy. They occupy a core position in energy storage systems. Therefore, the mounting brackets for the batteries are particularly important, needing to meet requirements in areas such as structural strength, material selection, installation, ventilation and heat dissipation, safety protection, ease of maintenance, electrical safety, environmental adaptability, and regulatory standards to ensure the safe, stable, and efficient operation of the battery pack.

[0003] Currently, the common structure for energy storage boxes is a metal fixed cluster frame, with the battery cluster frame modules directly welded to the box body. During transportation, energy storage boxes inevitably encounter vibrations, and this type of installation structure can lead to the following problems:

[0004] 1) Uneven road surfaces and vibrations and impacts from sudden braking may cause the battery casing to deform or crack, affecting structural integrity. Furthermore, it may loosen or displace internal battery components, impacting performance and safety.

[0005] 2) Vibration may cause the battery connectors to loosen, leading to poor contact or short circuit.

[0006] To address the aforementioned problems, we propose a shock-absorbing structure for battery cluster frames in energy storage boxes. Utility Model Content

[0007] The purpose of this invention is to provide a shock-absorbing structure for a battery cluster frame in an energy storage box, so as to solve the problems mentioned in the background art.

[0008] To achieve the above objectives, this utility model provides the following technical solution:

[0009] A battery cluster frame shock absorption structure for an energy storage box includes:

[0010] A battery cluster rack, and several bottom crossbeams of the battery cluster rack installed at the bottom of the battery cluster rack. A shock absorber connecting plate is installed at the bottom of the bottom crossbeams of the battery cluster rack, and a bottom longitudinal beam of the base frame is installed at the bottom of the shock absorber connecting plate. Several shock absorbers are installed between the shock absorber connecting plate and the bottom longitudinal beam of the base frame to provide shock absorption support for the battery cluster rack.

[0011] Preferably, the bottom crossbeam of the battery cluster frame is fixed to the shock absorber connecting plate by bolts.

[0012] Preferably, the shock absorber connecting plate has a "U" shaped structure.

[0013] Preferably, the shock absorber includes:

[0014] The shock absorber includes a top cover and a bottom plate, with a shock-absorbing spring and a damper installed between the top cover and the bottom plate.

[0015] Preferably, the shock absorber top cover is bolted to the bottom of the shock absorber connecting plate.

[0016] Preferably, the shock absorber base plate is bolted to the top of the bottom longitudinal beam of the base frame.

[0017] Preferably, the top cover of the shock absorber and the bottom plate of the shock absorber are elastically connected by a shock-absorbing spring and a damper.

[0018] Compared with the prior art, the beneficial effects of this utility model are:

[0019] This invention optimizes the installation method of the battery cluster rack from the traditional welding to a detachable bolt connection.

[0020] This invention effectively mitigates vibrations during the transportation of the energy storage box using a shock absorber, thus providing significant protection for the battery. Attached Figure Description

[0028] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0029] Example 1:

[0030] Please see Figure 1-3 A battery cluster frame shock absorption structure for an energy storage box, comprising:

[0031] The battery cluster frame 1, and several battery cluster frame bottom crossbeams 2 installed at the bottom of the battery cluster frame 1. A shock absorber connecting plate 3 is installed at the bottom of the battery cluster frame bottom crossbeam 2. The shock absorber connecting plate 3 has a "U" shaped structure. The battery cluster frame bottom crossbeam 2 and the shock absorber connecting plate 3 are fixed by bolts. A base frame bottom longitudinal beam 5 is installed at the bottom of the shock absorber connecting plate 3. Several shock absorbers 4 are installed between the shock absorber connecting plate 3 and the base frame bottom longitudinal beam 5 to provide shock absorption support for the battery cluster frame 1.

[0032] In this embodiment, the shock absorber connecting plate 3 is installed at the bottom of the bottom crossbeam 2 of the battery cluster frame by bolts, and the shock absorber 4 is installed between the shock absorber connecting plate 3 and the bottom longitudinal beam 5 of the base frame by bolts. The bottom longitudinal beam 5 of the base frame is also fixedly connected to the energy storage box by bolts. The shock absorber 4 provides elastic support for the battery cluster frame 1 to buffer the vibration of the battery cluster frame 1 during the transportation of the energy storage box and to provide buffer protection for the batteries installed inside the battery cluster frame 1. Alternatively, the shock absorber 4 can be installed on one side of the battery cluster frame 1 and fixed to the energy storage box to buffer the lateral force on the battery cluster frame 1. Or, two adjacent battery cluster frames 1 can be connected by the shock absorber 4 to buffer the collision intensity between two adjacent battery cluster frames 1, thereby providing buffer protection for the battery cluster frame 1 and protecting the batteries.

[0033] Example 2:

[0034] like Figure 2 and Figure 3 As shown, the shock absorber 4 includes:

[0035] The shock absorber top cover 41 and the shock absorber base plate 42 are bolted to the bottom of the shock absorber connecting plate 3 and bolted to the top of the bottom longitudinal beam 5 of the base frame. A shock absorber spring 43 and a damper 44 are installed between the shock absorber top cover 41 and the shock absorber base plate 42, and the shock absorber top cover 41 and the shock absorber base plate 42 are elastically connected by the shock absorber spring 43 and the damper 44.

[0036] In this embodiment, when the shock absorber top cover 41 is subjected to force, the pressure is applied to the shock absorber spring 43 and damper 44 between the shock absorber top cover 41 and the shock absorber base plate 42. The shock absorber spring 43 and damper 44 can be used to provide the impact strength of the shock absorber top cover 41 and the shock absorber base plate 42. Since one side of the shock absorber top cover 41 is folded inward, the cross-section of the shock absorber base plate 42 has an "I" shaped structure, which can prevent the shock absorber top cover 41 and the shock absorber base plate 42 from separating and ensure that the shock absorber spring 43 and damper 44 effectively buffer the impact strength.

[0037] Although embodiments of the present invention have been shown and described, it will be understood by those skilled in the art that various changes, modifications, substitutions and alterations can be made to these embodiments without departing from the principles and spirit of the present invention, the scope of which is defined by the appended claims and their equivalents.
