Obviously, the described embodiments are only some embodiments of the present invention, and not all embodiments. Based on the embodiments of the present invention, all other embodiments obtained by those skilled in the art without creative effort are within the scope of protection of the present invention.

[0026] Specific implementation examples are given below.

[0027] like Figures 1 to 5As shown in the embodiment of the present invention, the modular housing structure of the photovoltaic inverter that enables rapid assembly includes a lower housing 1 and an upper housing 2. Multiple branch plates 3 are fixedly connected to both sides of the lower housing 1. An installation unit 6 is provided on the outer side of the upper housing 2. A door 4 is provided on the front side of the lower housing 1. A fixing cover 5 is fixedly connected to the upper side of the upper housing 2. The installation unit 6 includes a positioning groove 613, which is opened on the upper side of the branch plate 3. A positioning box 614 is provided on the inner side of the positioning groove 613. A positioning plate 61 is fixedly connected to the upper side of the positioning box 614. A top plate 62 is fixedly connected to the upper side of the positioning plate 61. A U-shaped plate 63 is fixedly connected to the upper side of the top plate 62. Through the configuration of the upper housing 1 and the lower housing 2, the photovoltaic inverter housing is configured as a modular structure, which facilitates the handling and transportation of the housing.

[0028] Two guide plates 67 are fixedly connected to the upper side of the upper housing 2. A guide block 68 is slidably connected to the outer side of the guide plate 67. A second rotating block 69 is fixedly connected to the upper side of the guide block 68. An inclined plate 66 is rotatably connected to the outer side of the second rotating block 69. A first rotating block 65 is fixedly connected to the front side of the U-shaped plate 63. The inclined plate 66 and the first rotating block 65 are rotatably connected. A connecting plate 610 is fixedly connected between the two guide blocks 68. A screw 611 is rotatably connected to the inner side of the fixed cover 5. The screw 611 is threadedly connected to the connecting plate 610. The front end of the screw 611 passes through the front side of the fixed cover 5 and is fixedly connected to a rotating cap 612. A slide rod 64 is fixedly connected to the upper side of the upper housing 2. The U-shaped plate 63 is slidably connected to the slide rod 64. Multiple positioning plates 61 are slidably connected to the upper housing 2. The U-shaped plate 63 is slidably connected to the fixed cover 5. The positioning box 614 is adapted to the positioning groove 613.

[0029] During assembly, the upper housing 2 is first placed on the lower housing 1. Then, the rotating cap 612 is rotated, which drives the screw 611 to rotate. The screw 611 drives the connecting plate 610 to move forward. The connecting plate 610 drives the guide block 68 to move. The guide block 68 drives the inclined plate 66 to rotate. The inclined plate 66 drives the U-shaped plate 63 to descend. The U-shaped plate 63 drives the top plate 62 to descend. The top plate 62 drives the positioning plate 61 to descend. The positioning plate 61 drives the positioning box 614 to descend, so that the positioning box 614 is inserted into the inner side of the positioning groove 613, which facilitates the initial positioning of the lower housing 1 and the upper housing 2.

[0030] The positioning groove 613 has reinforcing grooves 618 on both its front and rear inner walls. A reinforcing block 617 is provided on the inner side of the reinforcing groove 618. A sliding plate 616 is fixedly connected to the outer side of the reinforcing block 617. A fixing block 615 is fixedly connected to the inner side of the positioning box 614. The sliding plate 616 and the fixing block 615 are slidably connected. A storage slot adapted to the reinforcing block 617 is provided on the outer side of the positioning box 614. A rectangular groove 619 is provided on the outer side of the sliding plate 616. A linkage plate 620 is rotatably connected to the inner side of both rectangular grooves 619. A connecting block 62 is rotatably connected to the outer side of the linkage plate 620. 1. A lifting block 622 is fixedly connected to the lower side of the connecting block 621. Two linkage plates 620 are symmetrically distributed. The lifting rod 623 is slidably connected to the positioning box 614. The reinforcing block 617 is made of soft rubber material. The lifting rod 623 is fixedly connected to the lower side of the lifting block 622. The lower end of the lifting rod 623 passes through the lower side of the positioning box 614 and is fixedly connected to a contact block 625. A contact groove is opened on the lower side of the positioning box 614. The contact groove is adapted to the contact block 625. A spring 624 is fixedly connected between the lower side of the lifting block 622 and the inner wall of the positioning box 614.

[0031] When the positioning box 614 is inserted into the inner side of the positioning groove 613, the positioning box 614 drives the contact block 625 to contact the inner wall of the positioning groove 613. The positioning box 614 continues to descend, causing the contact block 625 to drive the lifting rod 623 to rise. The lifting rod 623 drives the lifting block 622 to rise. The lifting block 622 drives the linkage plate 620 to rotate. The linkage plate 620 drives the slide plate 616 to move. The slide plate 616 drives the reinforcing block 617 to move, so that the reinforcing blocks 617 on both sides move to the inner side of the reinforcing groove 618, which facilitates further reinforcement and increases the stability of the assembly. When disassembling, the positioning box 614 rises (because the reinforcing block 617 is made of soft material, the reinforcing block 617 is retractable and will not affect the rise of the positioning box 614). Under the action of the spring 624, the lifting block 622 and the reinforcing block 617 are reset.

[0032] During operation, the upper housing 2 is placed on the lower housing 1, and then the rotating cap 612 is rotated to drive the screw 611 to rotate. The screw 611 drives the connecting plate 610 to move. Under the action of the guide block 68, the inclined plate 66, and the U-shaped plate 63, the positioning plate 61 on the top plate 62 is controlled to descend, so that the positioning plate 61 drives the positioning box 614 to insert into the inner side of the positioning groove 613 for initial positioning. When the positioning box 614 is inserted into the inner side of the positioning groove 613, under the action of the contact block 625, the lifting rod 623, the lifting block 622, the linkage plate 620, and the sliding plate 616, the reinforcing blocks 617 on both sides are moved to the reinforcing groove 618 for reinforcement, which facilitates the rapid assembly of the outer shell.

Those skilled in the art should understand that the present invention is not limited to the above embodiments. The embodiments and descriptions in the specification are merely illustrative of the principles of the invention.
