[0028] The following is combined with Figures 1 to 7 This application is described in further detail.

[0029] The embodiment of the present application discloses a photovoltaic inverter device, which improves installation efficiency through quick docking installation, and improves anti-slip performance by means of pressing clamping and air suction during the installation process. The present application supports and installs on both sides of the back of the inverter body 1.

[0030] Reference Figures 1 to 3 , Figure 7 As shown, a photovoltaic inverter device disclosed in this embodiment includes an inverter body 1, a connector 2, a support member 3, a storage shell 4, a hanging assembly 5, and a thickening plate 6. The inverter body 1 is a fixed base, the connector 2 is installed at the back position of the inverter body 1, the support member 3 is rotatably arranged in the storage shell 4, and the storage shells 4 are detachably connected with a support rod. The support member 3 has a storage position and a supporting position during the rotation process in the storage shell 4. The inverter body 1 is supported by the connection between the support member 3 and the connector 2. The hanging assembly 5 is installed on the thickening plate 6, and the thickening plate 6 is installed at the rear end position of the storage shell 4.

[0031] Reference Figure 3 As shown, the hanging assembly 5 includes a pressing piece 51, which is horizontally slidably arranged in a movable groove opened in the thickening plate 6. The upper end of the thickening plate 6 is connected to the upper end of the hanging piece 52. When the support member 3 rotates to the supporting position, the pressing piece 51 is squeezed backward and air suction is generated. The lower end of the hanging piece 52 is horizontally slidably arranged with a limiting piece 53. The mounting frame is wrapped and clamped in position by the backward moving pressing piece 51, the hanging piece 52 and the limiting piece 53.

[0032] During the actual installation process, the personnel arrive at the installation position, hang the hanging member 52 on the mounting frame, and rotate the support member 3 of the storage position forward (when the support member 3 is in a vertical state, it is completely hidden and stored in the storage shell 4, and is in the storage position at this time) to connect it with the connecting member 2, and then under the gravity of the inverter body 1, the support member 3 is further rotated. When the support member 3 is rotated to the supporting position, the front end position angle of the connecting member 2 and the support member 3 is locked, and the inverter body 1 is supported by the support member 3, and the rear end of the support member 3 is against the pressing member 51 to move it backward, thereby performing air suction pressing and positioning on the front end surface of the mounting frame, and then the limiting member 53 is inserted forward to limit the lower end of the hanging member 52. The present application is a detachable structure as a whole, which is conducive to quick disassembly and assembly, and improves disassembly and assembly efficiency.

[0033] Reference Figure 3 , Figure 5 As shown, in order to ensure that the front end of the support member 3 is in rotational connection with the connecting member 2 during the rotation process, when the support member 3 rotates to the supporting position, the support member 3 and the connecting member 2 are instantly locked. The present application makes further structural design to the structure of the support member 3 and the connecting member 2. The specific structure is as follows: the connecting member 2 includes a connecting frame 21, a positioning plug-in 22, and a locking member 23. The connecting frame 21 is installed at the back position of the inverter body 1. The positioning plug-in 22 is slidably set at the outer position of the connecting frame 21 along the width direction of the inverter body 1. The locking member 23, the middle of which is installed at the upper end of the connecting frame 21, and the locking member 23 is connected to the upper end of the positioning plug-in 22.

[0034] Reference Figure 4 , Figure 5 As shown, the positioning plug-in 22 includes a positioning column 221, a connecting plate 222, and a connecting spring 223. The positioning column 221 is slidably set at the outer position of the connecting frame 21 along the width direction of the inverter body 1. The outer side of the positioning column 221 is connected to the lower end of the connecting plate 222. A connecting spring 223 is connected between the middle part of the connecting plate 222 and the connecting frame 21, and a handle structure is installed on the outer wall of the connecting plate 222.

[0035] Reference Figure 4 , Figure 5As shown, the locking member 23 includes a connecting sleeve 231, a locking head 232, a connecting head 233, an internal spring 234, a guide slider 235, a guide groove 236, and a U-shaped member 237. The connecting sleeve 231 is installed at the upper end of the connecting frame 21, the locking head 232 is slidably arranged at the lower end of the connecting sleeve 231, and the internal spring 234 is connected between the locking head 232 and the connecting head 233 slidably arranged at the upper end of the connecting sleeve 231. The guide slider 235 is slidably arranged at the opening of the connecting head 233. In the guide groove 236, the guide groove 236 is a structure that gradually tilts downward from the inside to the outside. The design of the inclined structure of the guide groove 236 enables the guide slider 235 that moves synchronously to squeeze the connecting head 233 upward under the guidance of the guide groove 236 when the U-shaped part 237 moves outward. Conversely, when the U-shaped part 237 moves inward, the connecting head 233 descends. The guide slider 235 is installed on the inner side of the U-shaped part 237, and the outer side of the U-shaped part 237 is connected to the upper end of the connecting plate 222 through a connecting rod.

[0036] Reference Figure 3 As shown, the support member 3 includes a rotating member 31 and an extrusion head 32. The rotating member 31 is rotatably arranged in the storage shell 4. After the front end of the rotating member 31 enters the connecting frame 21, it is pin-positioned by the positioning column 221. A snap-in groove is provided on the front end surface of the rotating member 31. After the rotating member 31 rotates to the supporting position, the locking head 232 is snapped into the snap-in groove. The extrusion head 32 is installed on the rear end of the rotating member 31. After the rotating member 31 rotates to the supporting position, the extrusion head 32 is against the inclined surface position of the movable groove. At this time, the rotating member 31 rotates to the maximum angle.

[0037] In the actual connection process, the handle is pulled outward, and the synchronously moving connecting plate 222 drives the positioning column 221 and the U-shaped member 237 to move outward. At this time, the positioning column 221 is pulled out from the inside of the connecting frame 21, and the guide slider 235 on the U-shaped member 237 drives the connecting head 233 to move upward under the guidance of the guide groove 236, so that the locking head 232 moves upward synchronously. At this time, the lower end surface of the locking head 232 is higher than the position of the clamping groove. After the inside of the connecting frame 21 is in an empty state, the front end of the rotating member 31 is inserted into the connecting frame 21, and then the handle is released. Under the action of the connecting spring 223, the connecting plate 222 drives the positioning column 221 and the U-shaped member 237 to move inwardly. At this time, the positioning column 221 is inserted into the circular hole opened at the front end of the rotating member 31, and the U The guide slider 235 on the molded part 237 drives the connecting head 233 to move downward under the guidance of the guide groove 236, so that the lower end surface of the locking head 232 elastically fits the front end arc surface of the rotating member 31 (because the height of the connecting head 233 is reduced at this time, the locking head 232 is synchronously reduced under the connection of the built-in spring 234, and the built-in spring 234 is in a compressed state due to the obstruction of the front end arc surface of the rotating member 31), and then the rotating member 31 is rotated until the extrusion head 32 is against the inclined surface position of the movable groove. At this time, the rotating member 31 is in the supporting position, and the locking head 232 is inserted into the clamping groove to lock the front end position of the rotating member 31. The position between the two is locked. When the inverter body 1 needs to be disassembled separately later, it only needs to pull the handle outward.

[0038] Reference Figure 3 As shown, a support frame 7 is horizontally slidably provided inside the storage shell 4 , and the lower end of the connection frame 21 is supported by the extended support frame 7 .

[0039] When the support member 3 rotates to the supporting position, the inverter body 1 is supported by the support member 3, and at the same time, the extended support frame 7 supports the lower end of the connecting frame 21, thereby improving the stability of the support and improving the supporting effect.

[0040] Reference Figures 2 to 3 , Figure 6As shown, the pressing piece 51 further presses the mounting frame and improves the positioning effect by air suction. Its specific structure is as follows: the pressing piece 51 includes a pressing plate 511, an extrusion block 512, an extrusion rod 513, and a piston plate 514. The pressing plate 511 is connected to the storage shell 4 through an elastic telescopic rod. The elastic telescopic rod always drives the pressing plate 511 to maintain a tendency to move forward. An air cavity is opened on the side of the pressing plate 511 away from the inverter body 1, and air holes are evenly opened on the air cavity. The extrusion block 512 is slidably arranged on the pressing plate 511. In the hidden groove opened in the plate 511, an extrusion rod 513, one end of which is used in cooperation with the inclined extrusion of the extrusion block 512, and a piston plate 514 is installed on the other end of the extrusion rod 513, and the piston plate 514 is slidably set in the L-shaped cavity, the L-shaped cavity is connected to the air cavity, and the inner side of the L-shaped cavity and the piston plate 514 are elastically connected. When the extrusion block 512 is not squeezed, the piston plate 514 moves to the corner position of the L-shaped cavity under the action of elasticity, and the extrusion rod 513 that moves synchronously squeezes the extrusion block 512 to make it extend out of the hidden groove.

[0041] During the actual clamping process, during the rotation of the rotating member 31, the extrusion head 32 contacts the extrusion block 512. As the rotating member 31 rotates further, the extrusion block 512 is squeezed and retracts into the air cavity. Under the squeezing of the extrusion block 512 on the extrusion rod 513 by the inclined surface, the piston plate 514 moves. Since the pressing plate 511 has been in contact with the surface of the mounting frame before the movement of the piston plate 514, during the movement of the piston plate 514, suction is generated according to the piston principle, so that the mounting frame is adsorbed on the pressing plate 511. At the same time, the pressing plate 511 as a whole also presses tightly against the front end surface of the mounting frame, cooperating with the rear end limit of the hanging member 52, thereby performing a hanging clamping positioning on the mounting frame.

[0042] Reference Figure 6 As shown, the limiting member 53 includes a latch member 531, a sliding member 532, and a snap-in member 533. The rear end of the latch member 531 is slidably arranged at the lower end position of the hanging member 52, and the front end of the latch member 531 is snapped into the snap-in groove opened at the lower end of the storage shell 4. The sliding member 532 is slidably arranged in the sliding groove opened at the lower end of the thickening plate 6. An inverted T-shaped member is arranged at the lower end of the sliding member 532, and the inverted T-shaped member is slidably arranged up and down in the inverted T-shaped groove opened by the snap-in member 533. The snap-in member 533 corresponds to the position of the groove opened on the upper side of the front end of the latch member 531.

[0043] Reference Figure 6 As shown, a magnetic groove is provided in the middle of the lower end of the pressing plate 511, a magnetic layer is laid in the magnetic groove, an iron layer is provided at the upper end of the sliding member 532, the positions of the magnetic groove and the iron layer correspond to each other, and an inclined structure is provided on the rear side of the lower end of the latch member 531, and the inclined structure is a structure that gradually inclines upward from front to back.

[0044] When the locking member 531 is in the locked position, the locking member 533 is in the locked position, and the locking member 533 is in the locked position. The front end surface is subjected to air suction + compression), at this time, the magnetic groove at the lower end of the pressing plate 511 and the position of the sliding member 532 are misaligned, and at this time, the upper end of the sliding member 532 is squeezed by the lower end surface of the pressing plate 511 to make it drop to the lowest position. At this time, the lower end surface of the clamping member 533 is lower than the upper end surface position of the horizontal part of the latch member 531. When the latch member 531 is inserted, the clamping member 533 that can slide up and down rises up under the squeezing between its inclined structure and the latch member 531 until it is stuck in the groove position. Since the front end surface of the clamping member 533 is a flat structure, the latch member 531 cannot retreat, thereby achieving a locking effect. If unlocking is required, the pressing plate 511 only needs to be reset.

[0045] Working principle:

[0046] Step 1: The personnel arrive at the location to be installed and conduct a structural inspection of the application;

[0047] Step 2: Hang the hanging member 52 on the mounting frame, rotate the support member 3 forward at an angle to connect it with the connecting member 2, and then the support member 3 is further rotated under the gravity of the inverter body 1. When the support member 3 is rotated to the supporting position, the connecting member 2 and the front end position of the support member 3 are locked at an angle, and the inverter body 1 is supported by the support member 3;

[0048] Step 3: While supporting, the rear end of the support member 3 abuts against the pressing member 51 to move it backwards, thereby performing air suction pressing and positioning on the front end surface of the mounting frame;

[0049] Step 4: Insert the limiting member 53 forward to limit the lower end of the hanging member 52, and the installation is completed;

[0050] Step 5: Connect and test the inverter body 1.

It is undoubted that those skilled in the art can modify the described embodiments in various ways without departing from the spirit and scope of the present invention.
