Description

Technical Field

[0001] This utility model relates to the technical field of energy storage inverters, specifically an external cooling fan assembly that can be pulled out from the side and an energy storage inverter. Background Technology

[0002] Residential energy storage inverters are one of the core components of home energy storage systems. They are responsible for energy conversion and management between photovoltaic power generation, battery energy storage, and household electricity consumption. Their external cooling fans are key components to ensure the long-term stable operation of the equipment. After long-term operation, they may accumulate dust, wear or malfunction, affecting heat dissipation efficiency or even causing the inverter to overheat and shut down. Therefore, regular maintenance is required.

[0003] Most existing external fans are assembled as a whole, requiring the fan assembly to be removed for cleaning or replacement during maintenance. Therefore, the installation and removal method of the fan assembly is particularly important, especially for low-voltage energy storage inverters with transformer assemblies at the bottom of the chassis. If the structural design is unreasonable, it will make the disassembly and assembly of the fan assembly difficult to maintain. In some cases, it may be necessary to remove the energy storage inverter from the mounting body to maintain the external fan assembly. Moreover, the external fan assembly is fixed to the energy storage inverter by threads, which means that external tools must be used to assist in the disassembly and installation of the external fan assembly, making the operation cumbersome and reducing the disassembly efficiency of the external fan assembly. Utility Model Content

[0004] The purpose of this invention is to provide a side-pull-out external cooling fan assembly and an energy storage inverter to solve the problems mentioned in the background art.

[0005] To achieve the above objectives, this utility model provides the following technical solution:

[0006] A side-pull-out external cooling fan assembly and energy storage inverter include a mounting bracket that can be plugged into the chassis body along the side of the chassis body. A cooling fan is detachably mounted on the mounting bracket.

[0007] The chassis body has bending plates at both ends, and slots are formed on the bending plates, with elastic locking components installed in the slots.

[0008] The mounting bracket has insert plates at both ends that can be inserted into slots, and the elastic locking member can lock the insert plates.

[0009] The external cooling fan assembly that can be pulled out from the side as described above: the mounting bracket is equipped with a wire harness bundling structure, which can fix the wire harness connected to the cooling fan.

[0010] As described above, the external cooling fan assembly that can be pulled out from the side has a first wire harness connector at the end of the wiring harness away from the cooling fan, and a second wire harness connector on the chassis body. The first wire harness connector and the second wire harness connector are connected by mating.

[0011] The external cooling fan assembly that can be pulled out from the side as described above: the elastic locking member includes a pressing block that is slidably disposed in the slot, the two ends of the pressing block are respectively formed with inclined surfaces, and the end of the pressing block away from the insert plate abuts against the unlocking member disposed on the bending plate;

[0012] It also includes a spring disposed in the slot, one end of the spring abutting against the compression block and the other end abutting against the inner end of the slot.

[0013] As described above, the external cooling fan assembly that can be pulled out from the side has a groove in the middle of the extrusion block and a through groove formed on the insert plate, the side end of which can be inserted into the groove.

[0014] As described above, the external cooling fan assembly that can be pulled out from the side: the unlocking component includes an unlocking block that is slidably disposed on the bending plate, one end of the unlocking block can be inserted into the slot and abut against the pressing block, and the other end extends out of the bending plate and is fixedly connected to a push plate.

[0015] An energy storage inverter includes the external cooling fan assembly that can be pulled out from the side as described in any one of the above claims.

[0016] Compared with the prior art, the beneficial effects of this utility model are:

[0017] When the mounting bracket is installed on the chassis, it moves along the length of the chassis side, allowing the insert plate to be inserted into the slot. The insert plate compresses the elastic locking element, which, after yielding to the insertion, locks the insert plate upon resetting under elasticity. This achieves a stable connection between the chassis and the mounting bracket. The external fan assembly and the energy storage inverter can be quickly disassembled and installed via a side-pull mechanism. This solves the problems of difficult, time-consuming, and labor-intensive operation during the disassembly, installation, and maintenance of existing low-voltage energy storage inverter cooling fan assemblies. It eliminates the need to remove the energy storage inverter from the mounting body, effectively improving the maintenance efficiency of the external fan assembly. Attached Figure Description

[0025] Various exemplary embodiments, features, and aspects of this application will now be described in detail with reference to the accompanying drawings. The same reference numerals in the drawings denote elements that have the same or similar functions. Although various aspects of the embodiments are shown in the drawings, they are not necessarily drawn to scale unless specifically indicated otherwise.

[0026] The term “exemplary” as used herein means “serving as an example, embodiment, or illustration.” Any embodiment illustrated herein as “exemplary” is not necessarily to be construed as superior to or better than other embodiments.

[0027] Furthermore, to better illustrate this application, numerous specific details are provided in the following detailed embodiments. Those skilled in the art should understand that this application can be implemented even without certain specific details. In some instances, methods, means, and elements well-known to those skilled in the art have not been described in detail in order to highlight the main points of this application.

[0028] Please see Figures 1-6 In this embodiment of the invention, a side-pull-out external cooling fan assembly includes a mounting bracket 1, which can be inserted into the chassis body along the side of the chassis body. A cooling fan 5 is detachably mounted on the mounting bracket 1.

[0029] The chassis body has bending plates 2 at both ends, and slots 201 are formed on the bending plates 2, and elastic locking elements are installed in the slots 201.

[0030] The mounting bracket 1 has insert plates 3 at both ends that can be inserted into slots 201, and the elastic locking member can lock the insert plates 3.

[0031] In this embodiment, when the mounting bracket 1 is installed with the chassis body, the mounting bracket 1 moves along the length of the side of the chassis body, so that the insert plate 3 can be inserted into the slot 201. The insert plate 3 can squeeze the elastic locking member, so that after the elastic locking member makes room for the insertion of the insert plate 3, it can lock the insert plate 3 when it resets under the elastic action, thereby realizing a stable connection between the chassis body and the mounting bracket 1. This solves the problem of difficult operation, time and labor cost in the disassembly and installation maintenance of the existing low-voltage energy storage inverter cooling fan assembly, thereby improving the maintenance efficiency of the external fan assembly.

[0032] For further solutions to this utility model, please refer to [link / reference]. Figure 4 The mounting bracket 1 is equipped with a wire harness bundling structure 6, which can fix the wire harness 4 connected to the cooling fan 5.

[0033] The end of the wiring harness 4 away from the cooling fan 5 is equipped with a first wiring harness connector, and the chassis body is equipped with a second wiring harness connector. The first wiring harness connector and the second wiring harness connector are connected by plugging them together.

[0034] Before installing mounting bracket 1 onto the chassis, connect the first and second wiring harness connectors by plugging them together. Then, push mounting bracket 1 into the insertion plate 3 and lock it into slot 201. The process is reversed when removing or maintaining the fan.

[0035] For further solutions to this utility model, please refer to [link / reference]. Figure 5 and Figure 6 The elastic locking member includes a pressing block 8 slidably disposed in the slot 201. The two ends of the pressing block 8 are respectively formed with inclined surfaces. The end of the pressing block 8 away from the insert plate 3 abuts against the unlocking member disposed on the bending plate 2.

[0036] It also includes a spring 7, which is disposed in the slot 201. One end of the spring 7 abuts against the pressing block 8, and the other end abuts against the inner end of the slot 201.

[0037] A groove 801 is provided in the middle of the extrusion block 8, and a through groove 301 is formed on the insert plate 3, the side end of the through groove 301 can be inserted into the groove 801.

[0038] Specifically, after the insert plate 3 is aligned and inserted into the slot 201, the end of the insert plate 3 presses against the inclined surface of the pressing block 8, causing the pressing block 8 to move towards the spring 7 under the inclined force, making room for the insertion of the insert plate 3. When the insert plate 3 moves to the side and aligns with the groove 801, the insert plate 3 is fully inserted into the slot 201, and the pressing block 8 is reset under the action of the spring 7, and the side of the insert plate 3 is inserted into the groove 801. The pressing block 8 locks the insert plate 3 to achieve a stable connection between the mounting bracket 1 and the chassis body. With the action of the unlocking component, no auxiliary tools are needed, which effectively increases the efficiency of disassembly and maintenance of the external fan assembly.

[0039] For further solutions to this utility model, please refer to [link / reference]. Figure 6 The unlocking component includes an unlocking block 9 that is slidably disposed on the bending plate 2. One end of the unlocking block 9 can be inserted into the slot 201 and abut against the pressing block 8, while the other end extends out of the bending plate 2 and is fixedly connected to a push plate 10.

[0040] When the external fan assembly is disassembled from the chassis body, by pressing the push plate 10 toward the bending plate 2, the unlocking block 9 exerts pressure on the squeezing block 8. The squeezing block 8 is pressed and then moves again to separate the squeezing block 8 from the plug plate 3, releasing the locking state of the plug plate 3. At this time, the mounting bracket 1 can be pulled out along the length of the side of the chassis body to separate from the chassis body.

[0041] An energy storage inverter includes the external cooling fan assembly that can be pulled out from the side as described in any one of the above claims.

[0042] It will be apparent to those skilled in the art that this invention is not limited to the details of the exemplary embodiments described above, and that it can be implemented in other specific forms without departing from the spirit or essential characteristics of this invention. Therefore, the embodiments should be considered illustrative and non-limiting in all respects, and the scope of this invention is defined by the appended claims rather than the foregoing description. Thus, it is intended that all variations falling within the meaning and scope of equivalents of the claims be included within this invention. No reference numerals in the claims should be construed as limiting the scope of the claims.

[0043] Furthermore, it should be understood that although this specification describes embodiments, not every embodiment contains only one independent technical solution. This narrative style is merely for clarity. Those skilled in the art should consider the specification as a whole, and the technical solutions in each embodiment can also be appropriately combined to form other embodiments that can be understood by those skilled in the art.
