[0002] In recent years, with the continuous development of energy storage equipment, users have increasingly higher requirements for the integration of home energy storage devices. Inverters, as crucial components in energy storage devices, require even higher integration. However, since inverters and energy storage devices are often designed as separate units, inverter manufacturers typically only design a single mounting solution, which cannot meet the integrated mounting requirements of energy storage integrators. Existing mounting structures include, for example, the Chinese utility model patent with application number CN202220906310.X, entitled "A Mounting Bracket for an Inverter and an Inverter Mounting Structure." Furthermore, some energy storage integrators often use fully enclosed sheet metal brackets for inverters that cannot meet installation requirements, which leads to wasted costs, increased weight, and reduced installation flexibility.

[0033] The upper support assembly 2 and the lower support assembly 3 are located on opposite end faces of the inverter body 1, respectively.

[0034] Both the rear bracket assembly 4 and the front bracket assembly 5 are located at the edges of the inverter body 1.

[0035] The two ends of the rear bracket assembly 4 are connected to the upper bracket assembly 2 and the lower bracket assembly 3, respectively;

[0038] As can be seen from the above description, the beneficial effects of this utility model are as follows: A fixing structure for an energy storage inverter, which fixes the inverter through four sets of bracket components and EVA compressed foam pads 6, thereby restricting the inverter's six degrees of freedom. The EVA compressed foam pads 6 have good shock absorption effect, and at the same time, facilitate overall installation without the risk of failure to fix due to dimensional tolerance changes. In addition, it can also avoid the vibration caused by gaps between metal parts during transportation, which may produce noise and shake, causing equipment failure. Compared with traditional fixing methods, the split bracket fixing scheme can better meet the structural design of diverse and highly integrated energy storage devices, reduce cost waste, reduce weight, enhance installation flexibility, and reduce installation difficulty.

[0039] Furthermore, the upper bracket assembly 2, the lower bracket assembly 3, the rear bracket assembly 4, and the front bracket assembly 5 are all sheet metal parts.

[0040] As described above, the lower bracket has locking holes for fastening with the rear and front brackets, facilitating bolt and nut fastening. The EVA mating surface of the upper bracket fits tightly against the upper surface of the inverter, and through the connection holes of the front and rear brackets, it is connected and secured with the front, rear, and lower brackets using bolts and nuts. The EVA foam pads on the brackets, through compression, better secure the inverter and also provide vibration damping.

[0042] As can be seen from the above description,

[0043] Furthermore, both the upper support assembly 2 and the lower support assembly 3 are equipped with bending handles 22.

[0044] As can be seen from the above description, the function of the bending handle 22 is to facilitate the overall handling of the equipment during the installation process and improve production efficiency. The folded handle structure on the upper edge of the lower support cooperates with the folded handle structure on the upper edge of the upper support, making it easier for installers to apply force to lift and move the inverter smoothly.

[0045] Furthermore, both the upper support assembly 2 and the lower support assembly 3 are provided with bent support edges.

The edge clamping structure on the lower bracket cooperates with the edge clamping structure on the upper bracket and fits against the side of the inverter. When the inverter is lifted, it can play a supporting role, so that the inverter can be better supported and lifted smoothly.

[0047] Furthermore, the upper support assembly 2 is provided with a grounding hole 23.

[0048] As can be seen from the above description, the upper bracket is provided with a grounding hole 23 to connect the inverter and its fixed bracket to the grounding hole on the equipment in a similar manner, so as to achieve grounding equipotential and provide product safety.

[0049] Furthermore, the upper support assembly 2 is provided with connection holes for energy storage devices.

[0050] As can be seen from the above description, there are three connection holes for energy storage devices on the lower bracket. These holes are designed to work in conjunction with the fixing holes on the upper bracket. After the inverter is fixed as a whole, it is fixed to the energy storage device using bolts and nuts.

[0051] Furthermore, the lower support assembly 3 is provided with an equipotential hole 31 that is locked to the inverter body 1.

[0052] As can be seen from the above description, the lower bracket is provided with an equipotential bonding hole 31 that cooperates with the inverter. The connection is achieved by bolt fastening, so as to realize the equipotential between the inverter and the bracket and improve the safety of the product.

[0053] Furthermore, the lower support assembly 3 is provided with cable tie holes 32.

[0054] As can be seen from the above description, the lower bracket is provided with cable tie holes 32, which is used to bind and organize the cable harness when the inverter output line is in use.

[0055] Furthermore, the front bracket assembly 5 is provided with a limiting stop 51 for limiting the inverter body 1.

[0056] As described above, the front bracket is equipped with an EVA foam pad that adheres to the inverter surface and is secured to the upper and lower brackets via bolts and nuts. Additionally, a limit stop 51 is provided on the front bracket to further restrict the inverter's freedom of movement. The EVA foam pad, through compression, adheres more tightly to the inverter and provides shock absorption.

[0062] EVA compressed foam pads 6 are provided between the inverter body 1 and the upper bracket assembly 2, lower bracket assembly 3, rear bracket assembly 4 and front bracket assembly 5.

[0063] The upper bracket assembly 2, lower bracket assembly 3, rear bracket assembly 4, and front bracket assembly 5 are all sheet metal parts.

[0064] In summary, the fixing structure of this utility model for the energy storage inverter uses four sets of bracket components and EVA compressed foam pads to fix the inverter, achieving the restriction of the inverter's six degrees of freedom. The EVA compressed foam pads have a good shock absorption effect, and at the same time, they facilitate overall installation without the risk of failure to fix due to dimensional tolerance variations.
