[0033] like Figures 1 to 5 As shown, an embodiment of the present invention provides a household energy storage split machine testing device, comprising a first test bench 1 for installing an inverter 5 of a household energy storage split machine and a second test bench 2 for installing a battery system 6 of the household energy storage split machine; the first test bench 1 is provided with a first connecting portion 3 and a storage space 7 adapted to the second test bench 2; the second test bench 2 is provided with a second connecting portion 4; the second test bench 2 is detachably connected to the first connecting portion 3 of the first test bench 1 through the second connecting portion 4; when the first connecting portion 3 is connected to the second connecting portion 4, the second test bench 2 and the battery system 6 installed on the second test bench 2 are both located in the storage space 7. Among them, the inverter 5 of the household energy storage split machine is installed on the first test bench 1, and the battery system 6 of the household energy storage split machine is installed on the second test bench 2. The first test bench 1 is provided with a storage space 7. When the second test bench 2 is connected to the first connection part 3 of the first test bench 1 through the second connection part 4, the second test bench 2 and the battery system 6 installed on the second test bench 2 are completely placed in the storage space 7, and the battery system 6 can also be protected at this time; when the second test bench 2 is separated from the first connection part 3 of the first test bench 1 through the second connection part 4, the second test bench 2 and the battery system 6 installed on the second test bench 2 can be taken out from the storage space 7.

[0034] In the present invention, since the inverter 5 is mounted on the first test bench 1 and the battery system 6 is mounted on the second test bench 2, the first test bench 1 is provided with a storage space 7 adapted for the second test bench 2. When the first connection portion 3 is connected to the second connection portion 4, the second test bench 2 and the battery system 6 mounted on the second test bench 2 are both placed in the storage space 7. At this time, it is convenient to perform a combined test on the inverter 5 and the battery system 6, and the footprint of the first test bench 1 and the second test bench 2 is reduced, saving the use space of the laboratory or production workshop and improving space utilization. When the second test bench 2 is separated from the first connection portion 3 of the first test bench 1 by the second connection portion 4, the second test bench 2 is removed from the storage space 7 of the first test bench 1, and the inverter 5 or the battery system 6 can be tested separately. In this way, the first test bench 1 and the second test bench 2 can be used separately or in combination, making the switching operation between the combined test and the separate test of the inverter 5 and the battery system 6 simple and quick, thereby improving the test efficiency.

[0035] In one embodiment, if Figure 3 As shown, the first test bench 1 includes a first frame 11 for mounting the inverter 5 and a second frame 12 connected to the first frame 11, the second frame 12 includes two first vertical brackets 122 connected to opposite sides of the first frame 11, and a first chassis 121 connected to one end of the two first vertical brackets 122 away from the first frame 11; the first test bench 1 also packages a first movable wheel group 13 mounted on the first chassis 121; a receiving groove 123 is provided on the first chassis 121, and the storage space 7 is surrounded by the second frame 12, the first vertical bracket 122, the receiving groove 123 and the first movable wheel group 13. It can be understood that the first test bench 1 is composed of a first frame 11 and a second frame 12, the inverter 5 is installed on the first frame 11, and the second frame 12 provides stable support for the first frame 11; the second frame 12 is composed of a first chassis 121 and two first vertical brackets 122 arranged on opposite sides of the first chassis 121, and the first vertical brackets 122 are connected between the first chassis 121 and the first frame 11; the storage space 7 is surrounded by the second frame 12, the first vertical bracket 122, the accommodating groove 123 and the first movable wheel group 13, and the storage space 7 is used to accommodate the second test bench 2, which improves space utilization and can also protect the battery system 6; the first movable wheel group 13 installed on the first chassis 121 allows the first test bench 1 to be easily moved between different positions to improve the flexibility and ease of use of the device.

[0036] In one embodiment, if Figures 4 and 5As shown, the second test bench 2 includes a second chassis 21 and a third frame 22 connected to the second chassis 21. The second chassis 21 includes a bottom plate 211 and first cross supports 212 connected to opposite sides of the bottom plate 211. The bottom plate 211, the first cross supports 212, and the third frame 22 define a protective installation space for mounting the battery system 6. The second test bench 2 also includes a second movable wheel set 23 mounted on the second chassis 21. It can be understood that the second chassis 21 and the first cross supports 212 mounted on opposite sides of the second chassis 21 constitute the second test bench 2. The second movable wheel set 23 mounted on the second chassis 21 allows the second test bench 2 to be easily moved between different locations, further improving the flexibility and ease of use of the device. The protective installation space defined by the bottom plate 211, the first cross supports 212, and the third frame 22 is used to mount the battery system 6, preventing direct impact or damage to the battery system 6 from external factors, while also facilitating installation, maintenance, and repair of the battery system 6.

[0037] In one embodiment, if Figure 2 As shown, the first connection portion 3 is mounted on the first chassis 121, and the second connection portion 4 is mounted on the bottom plate 211. It is understandable that the detachable connection between the first connection portion 3 of the first chassis 121 and the second connection portion 4 of the bottom plate 211 can realize a detachable connection between the first test bench 1 and the second test bench 2, thereby enabling separate and combined testing of the inverter 5 and the battery system 6.

[0038] In one embodiment, if Figure 2 As shown, the first connection portion 3 includes a screw 31 mounted on the first chassis 121 and a knob 32 connected to the screw 31, and the second connection portion 4 includes a threaded hole 41 provided on the base plate 211; the first test bench 1 is connected to the second test bench 2 by the screw 31 screwed into the threaded hole 41; it is understandable that when a combined test of the inverter 5 and the battery system 6 is required, the second test bench 2 only needs to be moved into the storage space 7 of the first test bench 1, and then the screw 31 is screwed into the threaded hole 41 of the base plate 211 by the knob 32, so that the two test benches can be quickly connected together. When it is necessary to test the inverter 5 and the battery system 6 separately, the first test bench 1 and the second test bench 2 can be easily separated by rotating the knob 32 and unscrewing the screw 31 from the threaded hole 41, so that the inverter 5 and the battery system 6 can be tested independently.

[0039] In another embodiment, the first connecting portion 3 includes a first clamping portion (not shown) mounted on the first chassis 121, and the second connecting portion 4 includes a second clamping portion (not shown) disposed on the bottom plate 211. The first test bench 1 is clamped to the second clamping portion of the second test bench 2 via the first clamping portion. It is understood that the first clamping portion is mounted on the first chassis 121 and includes, but is not limited to, a slot, a buckle, or a tongue. The second clamping portion is mounted on the bottom plate 211 and includes, but is not limited to, a protrusion that matches the slot, a buckle that matches the buckle, or a groove that matches the tongue. When it is necessary to connect the first test bench 1 and the second test bench 2, it is only necessary to align the first clamping portion and the second clamping portion and apply a certain pressure to make the two dock and fit together; when it is necessary to separate the first test bench 1 and the second test bench 2, the appropriate separation method and force can be determined according to the specific design of the first clamping portion and the second clamping portion, and the first test bench 1 can be gently pulled backward or outward (or the second test bench 2 can be pushed) to gradually loosen the fit between the clamping portions until the first clamping portion and the second clamping portion are completely disengaged.

[0040] In one embodiment, the first connecting portion 3 further includes a clamping plate (not shown) protruding from the inner side wall of the receiving groove 123 and a first screw hole (not shown) provided on the clamping plate. The second connecting portion 4 further includes a fixing ear plate (not shown) provided on the side wall of the bottom plate 211 and a second screw hole (not shown) provided on the fixing ear plate. When the clamping plate is engaged with the fixing ear plate, the first test bench 1 is connected to the second test bench 2 by bolts passing through the first screw hole and the second screw hole. It is understandable that when the first test bench 1 and the second test bench 2 need to be connected, the second test bench 2 is moved into the storage space 7 of the first test bench 1, the clamping plate is aligned and engaged with the fixing ear plate, and then the first test bench 1 and the second test bench 2 are securely connected together by bolts passing through the first screw hole and the second screw hole. When the first test bench 1 and the second test bench 2 need to be separated, the bolts are simply loosened to release the engagement between the clamping plate and the fixing ear plate.

[0041] In one embodiment, if Figures 1 to 4As shown, the first chassis 121 and the second chassis 21 are located on the same plane; the household energy storage split machine testing device also includes a slide groove (not shown) provided on the two opposite inner side walls of the receiving groove 123, and a slide rail (not shown) provided on the opposite sides of the second chassis 21; when the second test bench 2 enters the storage space 7, the slide rail is slidably inserted into the slide groove. It can be understood that when performing a combined test, it is only necessary to gently push the second test bench 2 into the storage space 7 of the first test bench 1, so that the second test bench 2 moves along the slide rail toward the slide groove direction of the receiving groove 123. As the second test bench 2 is pushed forward, the slide rail will gradually slide into the slide groove until the second test bench 2 completely enters the storage space 7. On the contrary, when performing a separate test, it is only necessary to reverse the operation and gently pull the second test bench 2 so that it slides out of the storage space 7 along the track of the slide rail and the slide groove.

[0042] In one embodiment, the end of the chute is provided with a guide opening (not shown) for guiding the slide rail into the chute. It is understood that the guide opening at the end of the chute serves a guiding and positioning function. At the initial contact point of the slide rail entering the chute, the guide opening can accurately guide the slide rail into the chute, avoiding jamming or damage caused by directional deviation or inaccurate positioning during the sliding process.

[0043] In one embodiment, if Figure 3 As shown, the first test bench 1 further includes a support ramp 14 connected between the first frame 11 and the second frame 12. It is understood that the support ramp 14 can be symmetrically connected to opposite sides of the first frame 11 and the second frame 12, thereby increasing the structural strength of the first test bench 1 and helping to resist various forces and vibrations that may be generated during the test process.

[0044] In one embodiment, if Figure 3 As shown, the first frame 11 includes a mounting plate 111 for mounting the inverter 5 and a plurality of mounting holes 112 spaced apart on the mounting plate 111. It is understood that the mounting plate 111 is used to mount the inverter 5, ensuring a stable and appropriate mounting position for the inverter 5 on the first test bench 1. The provision of the plurality of mounting holes 112 allows for flexible adjustment of the mounting position of the inverter 5 based on the specific size and shape of the inverter 5 to accommodate different models of inverters 5. Furthermore, by selecting appropriate mounting holes 112, precise alignment of key components of the inverter 5 with the mounting plate 111 is ensured, facilitating connection and maintenance.

[0045] The embodiments described above are only used to illustrate the technical solutions of the present invention, rather than to limit the same. Although the present invention has been described in detail with reference to the aforementioned embodiments, those skilled in the art should understand that they can still modify the technical solutions described in the aforementioned embodiments, or make equivalent replacements for some of the technical features therein.
