Description
Technical Field
[0001] This utility model relates to the field of inverter technology, specifically an expandable solar inverter housing. Background Technology
[0002] The solar inverter housing is the external structure used to protect and support the internal circuitry and electronic components of the solar inverter. It is an important component of the inverter and is usually made of metal (such as aluminum alloy) or high-strength plastic. It has functions such as protection, heat dissipation, installation and fixation, and environmental adaptability.
[0003] In the current technology, the housing structure of solar inverters is mostly a fixed design. When users need to expand the internal space of the inverter housing to accommodate more auxiliary devices based on actual usage needs, it is difficult to increase the housing volume conveniently. It often requires a complicated modification process or cannot be effectively expanded, which reduces the overall flexibility and effectiveness of the solar inverter housing.
[0004] Therefore, there is a need for an expandable solar inverter housing to address the problem in existing technologies where the internal space of the solar inverter housing cannot be easily expanded according to usage requirements. Utility Model Content
[0005] The purpose of this invention is to provide an expandable solar inverter housing to solve the problem in the prior art that the internal space of the solar inverter housing is not easily expanded according to usage requirements.
[0006] To achieve the above objectives, the present invention provides the following technical solution: an expandable solar inverter housing, comprising an inverter housing, an expansion housing movably installed inside the inverter housing, a wiring slot formed on the inverter housing for wiring, a through slot formed on the inverter housing, and a sliding groove formed inside the inverter housing for guiding the expansion housing, wherein the inverter housing is provided with an expansion mechanism for driving the expansion housing to move.
[0007] The expansion mechanism includes a rectangular block fixedly connected to the inverter housing, a mounting slot formed in the rectangular block, a lead screw rotatably connected in the mounting slot, a movable block movably mounted on the lead screw, a guide rod fixedly connected in the mounting slot for guiding the movable block, a mounting cavity formed in the rectangular block, and a worm gear rotatably connected in the mounting cavity. The lead screw rotatably passes through the mounting cavity and is fixedly connected to a worm wheel that meshes with the worm gear. The worm gear rotatably passes through the rectangular block and is fixedly connected to a nut for driving the worm gear.
[0008] It should be noted in the solution that the expansion shell has a slot, and the slot has two card slots, in which the same baffle is movably inserted.
[0009] It is worth noting that a mounting frame is fixedly connected to the expansion shell, the mounting frame has a mating groove that matches the slot, and a side plate that is connected to the inverter housing is connected to the mounting frame by screws.
[0010] Furthermore, it should be noted that a connecting block is slidably connected within the through groove, and a slider is slidably connected within the sliding groove.
[0011] In a preferred embodiment, the connecting block is fixedly connected to the expansion shell and the movable block.
[0012] In a preferred embodiment, the slider is fixedly connected to the expansion shell.
[0013] Compared with the prior art, the beneficial effects of this utility model are:
[0014] By tightening the nut to drive the worm gear to rotate, the lead screw drives the moving block to move, and the moving block drives the expansion shell to move, thus expanding the volume of the inverter housing.

[0020] 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.
[0021] Example: Figures 1-4 As shown, this utility model provides a technical solution, including an inverter housing 1, an expansion shell 2 movably installed inside the inverter housing 1, a wiring group groove 3 opened on the inverter housing 1 for wiring, a through groove 4 opened on the inverter housing 1, and a sliding groove 5 opened inside the inverter housing 1 for guiding the expansion shell 2. An expansion mechanism 6 for driving the expansion shell 2 to move is provided on the inverter housing 1.
[0022] The extension mechanism 6 includes a rectangular block 61 fixedly connected to the inverter housing 1, a mounting groove 62 formed in the rectangular block 61, a lead screw 63 rotatably connected in the mounting groove 62, a movable block 64 movably mounted on the lead screw 63, a guide rod 65 fixedly connected in the mounting groove 62 for guiding the movable block 64, a mounting cavity 66 formed in the rectangular block 61, and a worm gear 68 rotatably connected in the mounting cavity 66. The lead screw 63 rotatably passes through the mounting cavity 66 and is fixedly connected to a worm wheel 67 that meshes with the worm gear 68. The worm gear 68 rotatably passes through the rectangular block 61 and is fixedly connected to a nut 69 for driving the worm gear 68.
[0023] Specifically, the operator rotates the screw cap 69 to drive the worm gear 68 to rotate. Through the meshing of the worm gear 68 and the worm wheel 67, the worm gear 68 drives the worm wheel 67 to drive the lead screw 63 to rotate. Under the action of the thread, the rotating lead screw 63 drives the moving block 64 to move. Under the guidance of the guide rod 65, the stability of the moving block 64 during movement is improved. At the same time, the movement of the moving block 64 drives the expansion shell 2 to move, thereby expanding the inverter housing.
[0024] Further as Figure 2 and Figure 3 As shown, it is worth noting that the expansion shell 2 has a slot 7, and two card slots 8 are provided in the slot 7. The same baffle 9 is movably inserted into the two card slots 8.
[0025] Specifically, when it is not necessary to expand the inverter housing, the baffle 9 is removed from between the two slots 8 to avoid obstructing or interfering with the wiring group slot 3. When it is necessary to expand the inverter housing, the wiring group slot 3 is exposed as the expansion shell 2 moves. At this time, the baffle 9 in the two slots 8 protects the components inside the housing.
[0026] Further as Figure 1 and Figure 2 As shown, it is worth noting that an installation frame 10 is fixedly connected to the expansion shell 2. The installation frame 10 has a mating groove 11 that matches the slot 7. A side plate 12 that is connected to the inverter shell 1 is connected to the installation frame 10 by screws.
[0027] Specifically, the mating slot 11 that matches the slot 7 allows the operator to easily disassemble the baffle 9. After the inverter housing is expanded, the side plate 12 is screwed onto the mounting frame 10 to protect the internal components of the inverter housing.
[0028] Further as Figure 3 As shown, it is worth noting that a connecting block 13 is slidably connected inside the through groove 4, and a slider 14 is slidably connected inside the slide groove 5.
[0029] Further as Figure 3 As shown, it is worth noting that the connecting block 13 is fixedly connected to the expansion shell 2 and the movable block 64.
[0030] Further as Figure 3 As shown, it is worth noting that the slider 14 is fixedly connected to the expansion shell 2.
[0031] Specifically, the connecting block 13 is used to connect the moving block 64 and the expansion shell 2. When the lead screw 63 drives the moving block 64 to move, it drives the expansion shell 2 to move synchronously. At the same time, the connecting block 13 and the through groove 4 slide together to improve the smoothness of the expansion shell 2 during movement. The cooperation between the sliding groove 5 and the slider 14 improves the stability of the expansion shell 2 during movement.
[0032] In summary: When the solar inverter housing is in normal use, after removing the side plate 12, the baffle 9 can be taken out from the slot 7 through the set slot 8, and then the side plate 12 can be reinstalled to ensure that the wiring group slot 3 is not blocked.
[0033] When the inverter housing 1 needs to be expanded according to usage requirements, the side plate 12 is first removed. Then, the screw cap 69 is rotated to drive the worm gear 68 to rotate. Under meshing action, the worm gear 68 drives the worm wheel 67 to drive the lead screw 63 to rotate. Under the action of the thread, the lead screw 63 drives the moving block 64 to move. The moving block 64 drives the connecting block 13 to move. Under the sliding engagement of the slide groove 5 and the slider 14, the moving block 64 drives the expansion shell 2 to slide outward from the inside of the inverter housing 1 through the connecting block 13, thereby expanding the volume of the inverter housing 1. This facilitates the addition of related auxiliary devices, thereby improving the performance of the solar inverter housing. The self-locking characteristics of the worm gear 67 and worm 68 enhance the stability of the expansion shell 2 after movement. Depending on the extent to which the expansion shell 2 slides out of the inverter housing 1, a suitable baffle 9 is selected for replacement to prevent the wiring slot 3 from being blocked. After replacing the side plate 12 with a longer screw, the expansion operation of the inverter housing 1 is completed. The operation is simple and effectively avoids the problem that the internal space of the solar inverter housing is not easily expanded according to usage requirements.

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.
