In addition, in this technical solution, the power control board is located between two rubber pads, and the rubber pad and the sleeve rod are fixedly connected, and the base is fixedly connected to each support column, which makes it inconvenient to disassemble the power control board, thereby reducing practicality.

Based on the embodiments in the utility model, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the utility model.

[0022] Embodiment 1:

[0023] like Figure 1 and Figure 4As shown, a power control board includes a bottom frame 1, a top frame 2 and a power control board body 3, wherein the power control board body 3 is located between the bottom frame 1 and the top frame 2, and a pressing groove 4 matching with the power control board body 3 is provided on the lower surface of the top frame 2, and a transparent protective cover 7 is rotatably connected to one side of the top of the top frame 2, and rubber protrusions 9 are fixedly connected to both sides of the outer surface of one end of the transparent protective cover 7, and fixing holes matching with the rubber protrusions 9 are provided on both sides of the inner wall of the top frame 2 (not shown in the figure). The rubber protrusions 9 can be compressed, so that when matched with the fixing holes, it is convenient to realize the opening and fixing and closing of the transparent protective cover 7.

[0024] Embodiment 2:

[0025] like Figure 1 and Figure 2 As shown, a heat dissipation mechanism 5 matched with the power control board body 3 is installed between the bottom frame 1 and the top frame 2, and the heat dissipation mechanism 5 includes two air inlets 51 symmetrically arranged on one side of the outer surface of the top frame 2, and two air outlets 52 are symmetrically arranged on the outer surface of the top frame 2 and on the side opposite to the air inlet 51, and a heat dissipation fan 53 is embedded and fixedly installed inside the air inlet 51. A plurality of heat sinks 54 are fixedly connected to the inside of the bottom frame 1 in sequence, and the top of the heat sink 54 contacts the lower surface of the power control board body 3 through thermal grease, and a dustproof net (not shown in the figure) is embedded and fixedly connected inside the air inlet 51 and the air outlet 52. When in use, when the heat dissipation fan 53 is in operation, it can drive the air flow inside the top frame 2, so that the heat at the top of the power control board body 3 can be taken away, thereby achieving the effect of heat dissipation on the top of the power control board body 3, and the heat sink 54 can dissipate heat to the bottom of the power control board body 3, thereby further increasing the heat dissipation effect, thereby solving the problem that the existing power control board only dissipates heat at the bottom, and the top is covered and cannot dissipate heat, which affects the heat dissipation effect.

[0026] Embodiment 3:

[0027] like Figure 1 and Figure 3As shown, a clamping mechanism 6 is installed between the bottom frame 1 and the top frame 2, and the clamping mechanism 6 includes a first vertical groove 61 opened on both sides of the outer surface of the top frame 2, and a groove 62 is opened on one side of the inner wall of the first vertical groove 61. A spring 63 is fixedly connected to the inside of the groove 62, and the other end of the spring 63 is fixedly connected to a slider 64 slidably connected to the inner wall of the groove 62, and the other end of the slider 64 is fixedly connected to an L-shaped clamping rod 65. The outer surface of the bottom frame 1 is provided with second vertical grooves 66 on both sides that match the first vertical grooves 61, and the inner wall of the second vertical grooves 66 is provided with a slot 67 that matches the L-shaped clamping rod 65. When it is necessary to disassemble the power control board body 3, it is only necessary to pull the two L-shaped clamping rods 65 outward to make the L-shaped clamping rods 65 disengage from the slots 67. At this time, the top frame 2 can be removed, so that the power control board body 3 can be disassembled and replaced. During installation, the top frame 2 is pressed downward. When the bottom end of the L-shaped clamping rod 65 coincides with the slot 67, the L-shaped clamping rod 65 will be driven to reset and be clamped into the slot 67 under the action of the spring 63, so that the installation of the power control board body 3 can be realized. The operation is simple and the disassembly and installation of the power control board body 3 are convenient, thereby solving the problem that the rubber pad and the sleeve rod of the existing power control board are fixedly connected, and the base is fixedly connected to each supporting column, which makes it inconvenient to disassemble the power control board, thereby reducing the practicality.

[0028] Embodiment 4:

[0030] Working principle: The top frame 2 and the transparent protective cover 7 can be provided to prevent dust from forming on the top of the power control board body 3. When in use, when the cooling fan 53 is running, the air flow inside the top frame 2 can be driven to take away the heat from the top of the power control board body 3, thereby achieving the effect of heat dissipation on the top of the power control board body 3. The heat sink 54 can dissipate heat from the bottom of the power control board body 3, thereby further increasing the heat dissipation effect, thereby solving the problem that the existing power control board only dissipates heat from the bottom and the top is covered and cannot dissipate heat, thus affecting the heat dissipation effect.

[0031] When it is necessary to disassemble the power control board body 3, it is only necessary to pull the two L-shaped clamping rods 65 outwards so that the L-shaped clamping rods 65 are disengaged from the clamping slots 67. At this time, the top frame 2 can be removed, so that the power control board body 3 can be disassembled and replaced. During installation, the top frame 2 is pressed downwards. When the bottom end of the L-shaped clamping rod 65 coincides with the clamping slot 67, the L-shaped clamping rod 65 will be driven to reset and be clamped into the clamping slot 67 under the action of the spring 63, so that the installation of the power control board body 3 can be realized. The operation is simple and convenient for disassembly and installation of the power control board body 3, thereby solving the problem that the existing power control board is located between the two rubber pads, and the rubber pads and the sleeve rods are fixedly connected, and the base is fixedly connected to each support column, which makes it inconvenient to disassemble the power control board, thereby reducing the practicality.

[0032] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model.
