[0036] Embodiment 1

[0037] The back-hanging structure provided in this embodiment is used for wall-mounted installation of a device. Specifically, the device can be an inverter 3.

[0038] As Figure 1 shown, a specific implementation of the back-hanging structure provided in this embodiment is a wall-end back-hanging member 1 and a device-end back-hanging member 2 that are mutually hung and matched. The wall-end back-hanging member 1 is used to be fixed on a wall, and the device-end back-hanging member 2 is used to be fixed on a device, which is a self-provided hook structure formed on the back of the inverter 3. There are several independently provided wall-end back-hanging members 1. It should be noted that in this embodiment, the device is an inverter 3.

[0039] For the back-hanging structure provided in this embodiment, since there are several independently provided wall-end back-hanging members 1, the position of the wall-end back-hanging member 1 on the wall can be flexibly adjusted according to the position of the device-end back-hanging member 2 on the device, so as to meet the wall-mounted installation of different models of devices, improve the compatibility of the back-hanging structure, and reduce the installation cost. Compared with the integral back-hanging structure in the prior art, it can be adapted to more devices and improve the compatibility of the installed devices.

[0040] As Figure 1 shown, in the back-hanging structure provided in this embodiment, the inductor box on the back of the inverter 3 forms the device-end back-hanging member 2 with a self-provided hook structure. As Figure 2 shown, specifically, the device-end back-hanging member 2 has two hook structures symmetrically arranged on the side of the inductor box. With this arrangement, during the hanging process, it is possible to observe whether the position is aligned from the side or the top, and the whole machine can also be horizontally fine-tuned and moved. Of course, the above description is not restrictive. In some alternative embodiments, the device-end back-hanging member 2 can also be a separate component and then connected to the inverter 3 by welding or other means.

[0041] As Figure 1 、 Figure 4As shown in the figure, in the wall-mounted structure provided in this embodiment, the wall-end wall-mounted part 1 has a hanging groove structure, and the device-end wall-mounted part 2 has a hook structure that matches the hanging groove structure. With this setting, during use, the hook structure of the device-end wall-mounted part 2 can be hooked onto the hanging groove structure of the wall-end wall-mounted part 1 to complete the hanging and matching of the two, making the hanging method more convenient for installers. Of course, the above description is not restrictive. In some alternative embodiments, the device-end wall-mounted part 2 can also be set as a hanging groove structure, and the wall-end wall-mounted part 1 can be set as a hook structure, etc.

[0042] As Figure 7 shown in the figure, in the wall-mounted structure provided in this embodiment, the wall-end wall-mounted part 1 includes: two bending parts 4 symmetrically arranged on both sides and a connecting part 5 connecting the two bending parts 4 in the middle. A hanging groove structure is formed between the connecting part 5 and the two bending parts 4. With this setting, the structure of the wall-end wall-mounted part 1 can be simplified, the cost of the wall-end wall-mounted part 1 can be reduced, and a hanging groove structure can be provided for matching with the hook structure of the device-end wall-mounted part 2. Of course, the above description is not restrictive. In some alternative embodiments, the wall-end wall-mounted part 1 can also be set in other shapes to form the hanging groove structure.

[0043] As Figure 1 shown in the figure, in the wall-mounted structure provided in this embodiment, on the plate surface of the bending part 4 parallel to the wall on both sides, there is a first through hole 6 for passing through a fastener. With this setting, the wall-end wall-mounted part 1 can be fixed to the wall surface through the cooperation of the fastener and the through hole; specifically, the fastener can be an expansion screw. Of course, the above description is not restrictive. In some alternative embodiments, the number of the first through holes 6 can also be set to multiple, or the first through hole 6 can also be cancelled according to the material of the installation wall surface. If it is installed on a metal wall surface, the wall-end wall-mounted part 1 can be fixed by welding.

[0044] As Figure 1 、 Figure 3 、 Figure 5 shown in the figure, in the wall-mounted structure provided in this embodiment, on the plate surface of the bending part 4 perpendicular to the connecting part 5, there is a second through hole 7 for passing through a lock 14. As Figure 2As shown in the figure, in the back-hanging structure provided in this embodiment, the device-side back-hanging member 2 has a third through-hole 15 for passing through the lock 14. With this arrangement, it is convenient to further reinforce the inverter 3 in the later stage through the lock 14. Specifically, after hanging the device-side back-hanging member 2 on the wall-side back-hanging member 1, the lock tongue of the lock 14 passes through the second through-hole 7 and the third through-hole 15, and the device-side back-hanging member 2 and the wall-side back-hanging member 1 can be locked, thereby avoiding the problem of theft. Of course, the above description is not restrictive. In some alternative embodiments, the lock 14 can be omitted, and the second through-hole 7 can also be omitted.

[0045] As Figure 7 shown in the figure, in the back-hanging structure provided in this embodiment, an installation direction mark 8 is provided on the outer wall surface of the connecting member 5. With this arrangement, the operation details can be clarified and the work efficiency of the installers can be improved. Of course, the above description is not restrictive. In some alternative embodiments, the installation direction mark 8 can also be omitted.

[0046] As Figure 1 shown in the figure, in the back-hanging structure provided in this embodiment, a fixing bracket 11 can also be included. The fixing bracket 11 has a first fixing portion 12 for fixing on the wall and a second fixing portion 13 for fixing on the inverter 3. The connection position of the second fixing portion 13 and the inverter 3 is located below the device-side back-hanging member 2. With this arrangement, the lower part of the inverter 3 lacking fixation can be integrally reinforced. Of course, the above description is not restrictive. In some alternative embodiments, the fixing bracket 11 can also adopt a design with a small volume and multi-point support.

[0047] Embodiment 2

[0048] As Figure 6 shown in the figure, a specific implementation manner of the back-hanging structure provided in this embodiment is that in the back-hanging structure provided in this embodiment, a plurality of device-side back-hanging members 2 are independently provided. As Figure 8 , Figure 9 , Figure 10 , Figure 11 shown in the figure, the device-side back-hanging member 2 includes: a mounting member 9 for abutting and connecting with the inverter 3 and a hook member 10 protruding outward perpendicular to the mounting member 9. The hook structure is formed on the hook member 10. With this arrangement, the stable connection between the device-side back-hanging member 2 and the inverter 3 can be realized, and at the same time, it can be stably hung on the hanging groove structure. Of course, the above description is not restrictive. In some alternative embodiments, the device-side back-hanging member 2 can be designed with different hook structures for different inverters 3.

[0049] As Figure 6As shown in the figure, in the wall-mounted structure provided in this embodiment, the hook structures of the device-side wall-mounted parts 2 can also have at least four that are arranged at intervals around the center of the inverter 3. By setting it in this way, the load capacity of the wall-mounted structure can be improved through more hooks, meeting the wall-mounted installation requirements of high-power inverters 3. Of course, the above description is not restrictive. In some alternative embodiments, the thickness of the hook parts 10 of the device-side wall-mounted parts 2 can be increased to enhance the load-bearing capacity.

[0050] Working principle:

[0051] According to the type of the inverter 3, if the inverter 3 does not have a self-provided hook structure, determine the number of hook parts 10 required for the device-side wall-mounted parts 2 of the installed inverter 3.

[0052] Take the corresponding number of wall-side wall-mounted parts 1, and determine the installation positions of the corresponding number of wall-side wall-mounted parts 1 according to the spacing of several device-side wall-mounted parts 2, and fix them to the wall surface through fasteners.

[0053] Fix the inverter 3 to the wall surface through the hanging connection of the device-side wall-mounted parts 2 and the wall-side wall-mounted parts 1.

[0054] Through the cooperation of the second through hole 7 and the third through hole 15, use the lock 14 for reinforcement.

[0055] When the inverter 3 needs to prevent being lifted, install the fixed bracket 11 on the second fixing part 13 of the inverter 3, and then fix it to the first fixing part 12 on the wall.

[0056] When installing a larger power inverter 3, select at least four device-side wall-mounted parts 2 structures that are arranged at intervals around the center of the inverter 3.

[0057] Obviously, the above embodiments are only examples given for clear illustration, rather than limitations on the implementation manners. For those of ordinary skill in the art, other different forms of changes or modifications can be made based on the above description. It is not necessary and impossible to list all the implementation manners here. And the obvious changes or modifications derived therefrom are still within the protection scope of the present utility model.
