Description

Technical Field

[0001] The invention belongs to the technical field of inverter equipment, in particular to a novel bidirectional inverter. Background Art

[0002] A bidirectional inverter refers to a device that can achieve bidirectional energy conversion. It can convert stored direct current into alternating current, and also convert alternating current into direct current to maintain the stable operation of the power grid. It is widely used in photovoltaic power generation, automobiles and other fields.

[0003] When the bidirectional inverter is in normal use, it relies on its internal electrical components and circuits to convert current. Therefore, during long-term use, the bidirectional inverter is prone to failure due to various factors, such as circuit board short circuit caused by excessive dust and moisture, circuit breakage caused by aging of components, etc. Therefore, in order to reduce the failure rate of the bidirectional inverter, it is usually necessary to perform regular maintenance on the internal components and circuits of the bidirectional inverter. When the bidirectional inverter fails, it is even more necessary to disassemble and repair the bidirectional inverter. During production, in order to reduce the volume of the bidirectional inverter as much as possible, the internal components and circuits of the bidirectional inverter are arranged more compactly. Therefore, during maintenance or overhaul, the small space causes great trouble to the staff. At the same time, the disassembly of more fixed structures leads to reduced convenience of maintenance and overhaul operations.

[0004] Related technology In order to enhance the convenience of maintenance and overhaul of bidirectional inverters, a convenient installation and disassembly method is usually adopted to combine components, circuit boards and shells, and remove the obstruction of the shell during maintenance and overhaul.

In view of this, the present invention proposes a new bidirectional inverter for solving the above-mentioned technical problems.

DETAILED DESCRIPTION

[0043] In order to make the technical means, creative features, objectives and effects achieved by the present invention easy to understand, the present invention is further explained below in conjunction with specific implementation methods.

[0044] like Figures 1 to 15 As shown, a novel bidirectional inverter described in the present invention comprises a housing 1 and a circuit board 11, wherein the circuit board 11 is installed in the housing 1, and components 12 are installed on the circuit board 11, and the circuit board 11 and the components 12 together constitute a bidirectional inverter circuit;

[0045] It also includes a dispersing assembly, which is used to disassemble the circuit board 11 and the components 12;

[0046] The dispersed assembly includes a connecting cable 2, the circuit boards 11 are designed in plural, the components 12 are dispersed on a plurality of circuit boards 11, and the plurality of circuit boards 11 are connected by connecting cables 2;

[0047] The limiting slot 21 and the plugging plate 22 , the housing 1 is provided with a limiting slot 21 , the edges of the circuit boards 11 are fixedly mounted with plugging plates 22 , and the plurality of circuit boards 11 are slidably connected to the limiting slot 21 through the plugging plates 22 .

[0048] The housing 1 includes a base 13 and an upper shell 14, the upper shell 14 is an L-shaped structure, and the upper shell 14 and the base 13 together form a hollow rectangular parallelepiped structure, a uniform clamping head 15 is fixedly installed on the end of the upper shell 14 with a longer length, and the base 13 is provided with uniformly distributed clamping grooves 16 corresponding to the clamping head 15, and the clamping grooves 16 and the clamping head 15 are both L-shaped structures, and a fastening bolt 17 is rotatably installed on the end of the upper shell 14 with a shorter length, and the base 13 and the upper shell 14 are firstly connected by the clamping grooves 16 and the clamping head 15, and then fixedly connected by the fastening bolts 17;

[0049] In the design of the bidirectional inverter, in order to reduce the volume of the bidirectional inverter, a circuit board 11 is usually used as a carrier of most components 12, so that the bidirectional inverter circuit is integrated, which leads to an increase in the density of components 12 on the bidirectional inverter. In order to enhance the convenience of overhauling and maintaining the bidirectional inverter, the present invention divides the entire bidirectional inverter circuit into multiple circuit boards 11, so that the bidirectional inverter circuit can be separated during overhaul and maintenance, thereby reducing the difficulty of overhaul caused by the centralization of components 12;

[0050] Specifically, the circuit board 11 and components 12 that constitute the entire bidirectional inverter circuit are relatively large in size, and multiple components 12 are adjacent to each other, resulting in a relatively narrow space during maintenance, which is inconvenient to operate. Therefore, in the present invention, during production and manufacturing, the circuit board 11 and components 12 are divided into multiple parts, and a connecting cable 2 is used to connect multiple circuit boards 11 in series and parallel. Multiple circuit boards 11 are installed with plug boards 22. During overall assembly, the plug boards 22 on the circuit board 11 are inserted into the limiting slots 21 provided on the base 13 of the shell 1, and then the multiple circuit boards 11 are regularly arranged in the base 13, and then the clamping head 15 on the upper shell 14 is aligned with the clamping slot 16 on the base 13, and the upper shell 14 and the base 13 are manually pushed to cause the upper shell 14 and the base 13 to engage. At this time, tighten the fastening bolts 17 with the help of a tool, so that the fastening bolts 17 extend into the base 13, thereby completing the installation of the bidirectional inverter. When maintaining or overhauling the bidirectional inverter, it is only necessary to loosen the fastening bolts 17 and manually push the upper shell 14 and the base 13, so that the clamping head 15 and the clamping slot 16 are misaligned, and the upper shell 14 and the base 13 can be separated, and then the multiple circuit boards 11 are removed. Since the multiple circuit boards 11 are connected by connecting cables 2, the connecting cables 2 are in a bent and folded state during assembly, resulting in a small gap between the multiple circuit boards 11. During overhaul, the multiple circuit boards 11 can be separated by manually pulling, thereby increasing the gap between the multiple circuit boards 11, which is convenient for the staff to overhaul the circuit boards 11 and the components 12 on the circuit boards 11;

[0051] The present invention divides the circuit board 11 and components 12 constituting the bidirectional inverter circuit equally and connects them through a connecting cable 2. In the assembly, the connecting cable 2 is folded and bent to reduce the size of the entire bidirectional inverter circuit. After being installed inside the housing 1, the bidirectional inverter is smaller in size. During maintenance, the multiple circuit boards 11 can be separated by manual pulling, thereby increasing the gap between the multiple circuit boards 11 for easy maintenance.

[0052] As a preferred embodiment of the present invention, it further comprises an integrated component, the integrated component is installed in the housing 1, and the plurality of circuit boards 11 are connected to each other through the integrated component;

[0053] The integrated assembly includes a slide seat 23, each of the circuit boards 11 is connected to the slide seat 23, and each of the slide seats 23 is provided with a dovetail groove 24;

[0054] A slide rail 25 is installed between two adjacent slide seats 23. The cross section of the slide rail 25 is a trapezoid, and the slide rail 25 matches the dovetail groove 24. The slide rail 25 is slidably connected to the slide seat 23;

[0055] The circuit board 11 is provided with a connection groove 26, and the slide seat 23 is fixedly mounted with a support rod 27, the support rod 27 matches the connection groove 26, and the support rod 27 is used to separate the slide seat 23 from the circuit board 11;

[0056] At least three connection slots 26 are formed on the same circuit board 11, and the plurality of connection slots 26 are arranged in a triangle shape;

[0057] Since the connecting cable 2 is made of soft material and does not have rigid support performance, the position fixation degree between the circuit board 11 and the components 12 constituting the entire bidirectional inverter circuit is low, which not only easily causes damage to the circuit board 11 and the components 12 under the action of external force during long-term use, but also is inconvenient for the staff to operate during loading and unloading. Therefore, the present application sets an integrated component and uses the integrated component to connect multiple circuit boards 11 into a whole. On the basis of retaining the ability to adjust the distance between the multiple circuit boards 11, the multiple circuit boards 11 form a rigid whole, thereby enhancing the convenience of loading and unloading the circuit board 11 and the components 12 constituting the entire bidirectional inverter circuit into the housing 1;

[0058] Specifically, after the connecting cable 2 is used to connect the multiple circuit boards 11 in series and in parallel according to the process requirements, the support rod 27 fixedly installed on the slide 23 is combined with the connecting groove 26 on the circuit board 11. Since the circuit board 11 is equipped with a slide 23, and a slide rail 25 is installed between two adjacent slides 23, the slide rail 25 matches the dovetail groove 24 provided on the slide 23. Therefore, the multiple slides 23 and the slide rail 25 form an adjustable distance whole, and then the structure formed by the multiple slides 23 and the slide rail 25 is used to support the multiple circuit boards 11. Under the connecting action of the support rod 27, the distance adjustment rules of the multiple circuit boards 11 are more orderly, and the multiple circuit boards 11 are always on the same plane. At the same time, in actual operation, the support rod 27 and the connecting groove 26 can be used The snap-fit ​​connection can also be made by wrapping elastic material around the support rod 27, so that the support rod 27 and the connecting groove 26 are interference-connected, so that the support rod 27 and the connecting groove 26 are stably connected when there is no external force, and there are at least three connecting grooves 26, and the multiple connecting grooves 26 are arranged in a triangle, so a single circuit board 11 is supported by at least three support rods 27, so that the support rod 27 can stably support the circuit board 11, and at the same time, the support of the circuit board 11 by the support rod 27, combined with the limiting slot 21 and the plug-in plate 22 on the circuit board 11, allows the circuit board 11 to stably hover in the inner cavity of the shell 1, that is, it can reduce the shielding of the slide seat 23 on the circuit board 11, enhance the heat dissipation performance of the circuit board 11, and during maintenance, it is also convenient to separate the slide seat 23, the slide rail 25 and other structures from the circuit board 11.

[0059] As a preferred embodiment of the present invention, the integrated assembly further includes a separation spring 28, and the separation spring 28 is fixedly mounted on the slide seat 23 and the slide rail 25;

[0060] Guide plates 3, two guide plates 3 of symmetrical design are installed on the base 13, the two guide plates 3 are arranged in an eight-shaped shape, and the guide plates 3 cooperate with the limiting slots 21 to guide the slide seat 23 and the slide rail 25 to overlap;

[0061] A deflection slot 31 and a limiting slot 32, wherein the base 13 is provided with a deflection slot 31, wherein the deflection slot 31 is conductively connected to the limiting slot 21, wherein the guide plate 3 is slidably mounted in the deflection slot 31, wherein the deflection slot 31 is open at one end away from the inner cavity of the base 13 and is arc-shaped, wherein the base 13 is provided with a limiting slot 32, wherein the guide plate 3 extends into the limiting slot 32, and wherein the length of the limiting slot 32 is less than the deflection slot 31;

[0062] In order to further enhance the convenience of the staff to inspect and repair the circuit boards 11 and components 12 that constitute the entire bidirectional inverter circuit, when the equipment is assembled, a separation spring 28 is installed between the slide seat 23 and the slide rail 25. When the slide seat 23 and the slide rail 25 are not restricted by the outside world, under the action of the separation spring 28, the two adjacent slide seats 23 have a tendency to slide on the slide rail 25 and move away from each other, and the multiple circuit boards 11 connected to the slide seat 23 through the support rod 27 have a tendency to disperse from each other. When it is installed in the housing 1, as the dispersed multiple circuit boards 11 gradually approach the guide plate 3, under the guiding and limiting action of the guide plate 3, the multiple circuit boards 11 are gradually compressed, causing the multiple circuit boards 11 to have a tendency to approach each other. Under the force conduction action of the support rod 27, the multiple slide seats 23 approach each other until the width of the whole formed by the multiple circuit boards 11 is When the distance between the two limit slots 21 is the same, the whole formed by the multiple circuit boards 11 is connected to the base 13 through the limit slots 21, and then the guide plate 3 is manually pushed to deflect, so that the guide plate 3 is finally received in the deflection groove 31, and the upper shell 14 is installed on the base 13, thereby completing the assembly of the equipment. During disassembly, after the upper shell 14 is separated from the base 13, when the whole formed by the slide seat 23 and the slide rail 25 lacks the restriction in one direction, under the action of the separation spring 28, the slide seat 23 moves in the corresponding direction, and then is manually pulled by the staff. When it is completely separated from the shell 1, under the action of the separation spring 28, the whole structure formed by the connection between the slide seat 23 and the slide rail 25 diffuses and expands, and the multiple circuit boards 11 connected thereto are quickly dispersed, thereby facilitating the staff to inspect and repair the circuit boards 11 and components 12.

[0063] As a preferred embodiment of the present invention, the integrated component further includes a winding ring, the middle part of the connecting cable 2 is wound on the winding ring, the winding ring includes a ring body 4 and a rotating shaft 41, a winding cavity 42 is opened inside the ring body 4, the winding cavity 42 is rotatably mounted with the rotating shaft 41, the winding cavity 42 is designed to be opened on the outer wall of the ring body 4, and a hook 43 is fixedly mounted on the rotating shaft 41;

[0064] The winding ring further comprises an adjusting ring 5 and a winding spring 51. An adjusting groove 53 is further provided in the ring body 4. The adjusting ring 5 is rotatably mounted in the adjusting groove 53, and the adjusting ring 5 extends to the outside of the ring body 4. The rotating shaft 41 extends into the adjusting groove 53. Two ends of the winding spring 51 are respectively fixedly connected to the adjusting ring 5 and the rotating shaft 41. A ratchet 54 is rotatably mounted in the adjusting groove 53. The outer wall of the adjusting ring 5 is ratchet-shaped, and the adjusting ring 5 matches the ratchet 54.

[0065] The circuit boards 11 are hingedly mounted with a pressing plate 6 on one side close to each other, and an elastic layer 61 is fixedly mounted on the pressing plate 6 on one side close to the circuit board 11. A fixed end 62 is fixedly mounted on the circuit board 11, and the fixed end 62 corresponds to the pressing plate 6 one by one. One side of the fixed end 62 is serrated, and the end of the pressing plate 6 is engaged and linked in the serrated gap of the fixed end 62.

[0066] In order to prevent the connection cable 2 from hindering the dispersion and aggregation of the multiple circuit boards 11, a winding ring and a pressing plate 6 are provided. When the circuit board 11 and the connection cable 2 are assembled, the multiple circuit boards 11 are not yet connected to the support rod 27. The pressing plate 6 is first pressed down to separate the saw teeth of the pressing plate 6 and the fixed end 62, and then the pressing plate 6 is rotated to open the gap between the pressing plate 6 and the circuit board 11. When the connection cable 2 is arranged, the connection cable 2 is passed through the gap between the pressing plate 6 and the circuit board 11, and then the pressing plate 6 is rotated again. The shortening of the distance between the pressing plate 6 and the circuit board 11 causes the connecting cable 2 to be fixed in the gap between the pressing plate 6 and the circuit board 11 under the action of the elastic layer 61. Then, the pressing plate 6 stays in the serrated gap between the fixing end 62 under the action of its own elasticity, so that the pressing plate 6 is fixed by the fixing end 62. Then, the middle part of the connecting cable 2 is clamped on the hook 43 on the rotating shaft 41, and the adjusting ring 5 is manually rotated. When the adjusting ring 5 rotates, the rotating shaft 41 is pulled by the winding spring 51, causing the connecting cable 2 to be gradually wound around the rotating shaft 41. When the connecting cable 2 is pulled, the circuit board 11 is moved back and forth, and the connecting cable 2 is pulled ...
