Technical Field

[0001] The utility model relates to the technical field of circuit boards, in particular to an anti-short circuit board for energy storage equipment. Background Art

[0002] Energy storage equipment circuit boards are circuit boards used in energy storage equipment. Its main function is to manage, protect and control the charging and discharging process of the energy storage system. Energy storage equipment circuit boards are widely used in the field of new energy, such as photovoltaic power generation, wind power generation, etc. In these fields, energy storage equipment circuit boards not only need to meet basic charging and discharging management functions, but also need to have advanced functions such as grid-connected and off-grid operation capabilities, automatic control capabilities, etc., to cope with various complex energy supply and demand scenarios.

[0003] Traditionally, circuit boards are installed and fixed by bolts, and the bolts themselves are made of metal and are conductive. If the bolts are not properly installed, they will contact different potential points on the circuit board, causing a short circuit. Therefore, there is an urgent need for an installation method that is not likely to cause a short circuit on the circuit board during the installation process. Utility Model Content

[0004] The utility model aims to solve the shortcomings in the prior art and proposes an anti-short circuit board for energy storage equipment.

[0005] In order to achieve the above purpose, the utility model adopts the following technical solutions:

[0007] In addition, a preferred structure is that both sides of the top of the mounting column corresponding to the limiting members are provided with insertion cavities downward, and the height of the insertion cavities is greater than the height of the limiting members.

[0008] In addition, a preferred structure is that a limiting cavity is provided on the installation column at the bottom of the insertion cavity, and the height of the limiting cavity is the same as the height of the limiting member.

[0009] In addition, a preferred structure is that an annular slider is fixedly provided at the bottom of the rotating column, and an annular sliding groove is adapted to be provided on the circuit board body corresponding to the annular slider located outside the installation cavity.

[0010] In addition, a preferred structure is that a rotating handle is fixedly provided on the top of the rotating column, and a soft anti-slip part is fixedly sleeved on the outer side wall of the rotating column.

[0011] In addition, a preferred structure is that a damping member is fixedly provided on one side of the rotating column above the circuit board body, a soft anti-slip member is laid on the inner wall of the damping member, and the damping member is adapted to the rotating column.

[0012] The beneficial effect of the utility model is that the fixed assembly of the circuit board body can be achieved by the mutual locking between the limiting piece in the rotating column and the limiting cavity in the mounting column.

DETAILED DESCRIPTION

[0019] The technical solutions in the embodiments of the present invention will be described clearly and completely below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all of the embodiments.

[0020] Reference Figure 1-5, a short-circuit-proof circuit board for energy storage equipment, including a circuit board body 1 and a mounting member 2, the circuit board body 1 is mounted on the external mounting member 2, the corners of the circuit board body 1 are vertically penetrated with mounting cavities 11, and the top of the mounting member 2 is adapted and fixedly provided with mounting columns 5 corresponding to the mounting cavities 11. A rotating column 3 is rotatably provided above the mounting cavity 11 on the circuit board body 1, an adjusting cavity 32 is provided at the bottom of the rotating column 3, and limiting members 8 are fixedly provided on both sides of the bottom of the inner wall of the adjusting cavity 32. The mounting member 2 is located on an external machine, and the circuit board body 1 can be installed by assembling the circuit board body 1 on the mounting member 2. It is also worth noting that the specific structures and working methods of the circuit board body 1 and the mounting member 2 are all existing technologies currently disclosed on the market, and they do not belong to the main technical features to be solved in the present technical solution, so they are not elaborated in the present utility model.

[0021] The top of the mounting column 5 has two sides corresponding to the stopper 8 with insertion cavities 51 downwardly opened, and the height of the insertion cavities 51 is greater than the height of the stopper 8. The bottom of the insertion cavity 51 on the mounting column 5 is connected with a limit cavity 52, and the height of the limit cavity 52 is the same as the height of the stopper 8. The circuit board body 1 can be assembled by clamping the limit cavity 52 with the stopper 8.

[0022] Among them, an annular slider 71 is fixedly provided at the bottom of the rotating column 3, and an annular slide groove 7 is adapted to be provided on the circuit board body 1 on the outer side of the installation cavity 11 corresponding to the annular slider 71. The specific structure and working mode of the annular slide groove 7 and the annular slider 71 are both existing technologies currently disclosed on the market, and they are not the main technical features to be solved in this technical solution, so they are not described in detail in this utility model. Through the provision of the annular slide groove 7 and the annular slider 71, the rotating column 3 can be located above the installation cavity 11 and rotate.

[0023] Among them, a rotating handle 31 is fixedly provided on the top of the rotating column 3, and a soft anti-skid member 6 is fixedly sleeved on the outer wall of the rotating column 3. A damping member 4 is fixedly provided on one side of the rotating column 3 above the circuit board body 1, and a soft anti-skid member 6 is laid on the inner wall of the damping member 4, and the damping member 4 is adapted to the rotating column 3. The soft anti-skid member 6 of the damping member 4 is in contact with the soft anti-skid member 6 on the rotating column 3, which can increase the friction force when the rotating column 3 rotates, thereby preventing the rotating column 3 from rotating spontaneously.

[0024] In this embodiment, when the user needs to install the circuit board body 1, it is only necessary to align the installation cavity 11 on the circuit board body 1 with the installation column 5 on the installation member 2. Then move the circuit board body 1 downward so that the installation column 5 is inserted into the installation cavity 11. Then the user can rotate the rotating column 3 by turning the handle 3. When the limiter 8 in the rotating column 3 is aligned with the insertion cavity 51 on the installation column 5, the limiter 8 can enter the insertion cavity 51, and at this time the installation column 5 also enters the adjustment cavity 32. Then continue to rotate the rotating column 3 so that the limiter 8 in the insertion cavity 51 moves into the limiter cavity 52, so that the limiter cavity 51 and the limiter 8 can be mutually locked. When the user has completed the locking of the limiters 8 at the four corners, the assembly of the circuit board body 1 can be completed.

[0025] Furthermore, when the user needs to remove the circuit board body 1, he only needs to rotate the rotating column 3 in the opposite direction to the end, and then the stopper 8 can be moved into the insertion cavity 51. At this time, the circuit board body 1 can be removed by pulling it vertically upward.

[0026] In the utility model, the fixed assembly of the circuit board body 1 can be achieved by the mutual locking between the limit piece 8 in the rotating column 3 and the limit cavity 52 in the mounting column 5. This assembly method is not only simple and convenient, but also will not cause a short circuit due to the contact between the bolts and the circuit board body 1 during the assembly process, which is convenient for the staff to use.

[0027] The above description is only a preferred specific implementation manner of the present invention, but the protection scope of the present invention is not limited thereto. Any technician familiar with the technical field can make equivalent replacements or changes within the technical scope disclosed by the present invention according to the technical scheme and the utility model concept of the present invention, which should be covered by the protection scope of the present invention.
