The aluminum substrate 11 component can be used as a mounting structure, and can also be used for heat dissipation. The power board 13 contacts the aluminum substrate 11 through thermal conductive silicone grease, which solves the problem of the power board 13 malfunctioning due to high heat. The setting of the insurance 127 plays a protective function in case of current overload to reduce product damage. The components are fixed with screws, which makes it more convenient and flexible to disassemble and remove. The overall assembly is simple, the time is greatly shortened, the defective rate is low, the difficulties in production are reduced, it is in line with economic benefits, and the application prospects are broad.

[0018] The power board 13 is welded with at least three three-phase AC aluminum columns 16 , the top ends of which extend to the top of the plastic cover 12 . The three three-phase AC aluminum columns 16 can also be connected to external direct current for power supply.

[0019] At least one copper pillar 18 is welded on the power board 13, and the top of the copper pillar 18 is connected to the bottom of the driving board 14. A white insulating sleeve is placed at the position corresponding to the copper pillar 18 on the driving board 14 and a screw is inserted and screwed into the copper pillar 18. The white insulating sleeve prevents the generation of current and causes short circuit and malfunction.

[0020] At least two copper bars 141 are welded on the top of the driving board 14, and at least one DC aluminum column 142 is provided on the opposite sides of the two copper bars 141. The top of the DC aluminum column 142 extends to the top of the plastic cover 12. The power board 13 and the driving board 14 use copper columns 18 to connect data signals, and the driving board 14 and the control board 15 use sockets and plugs to connect and transmit signals. The two DC aluminum columns 142 are input and output aluminum columns respectively, which are connected to external DC power.

[0021] The control board 15 is welded with a fuse 127 whose end is connected to one of the DC aluminum columns 142 to prevent excessive current and protect the product.

[0022] The design of the aluminum substrate 11 is designed with asymmetric threaded holes that lock with the power board 13, which can prevent the phenomenon of reverse installation and play a fool-proof role, greatly reducing the entire product controller being installed on the forklift using the screw holes on the aluminum substrate 11. The aluminum substrate 11 plays the main function of connecting parts while also playing the role of heat dissipation. The air valve 122 can release air without causing air trapping problems, including the overall temperature can be reduced to within the standard range, thereby improving the service life of the product.

Compared with the drive board 14 and the control board 15, the power board 13 generates the most serious heat. A layer of thermal conductive silicone grease is coated on the bottom of the power board 13, so that the heat of the power board 13 can be quickly conducted to the aluminum substrate 11 through the thermal conductive silicone grease and dissipated, thereby mostly ensuring the heat dissipation efficiency of the power board 13.

[0024] As a specific technical solution of this embodiment, corresponding hole positions 2 are provided on the power board 13 and the aluminum substrate 11, and a screw with one end screwed into the hole position 2 on the aluminum substrate 11 is provided inside the copper column 18, and an insulating sleeve is provided inside the copper column 18 to prevent the screw inside the copper column 18 from conductive contact with the copper column 18.

[0025] As a specific technical solution of this embodiment, the power board 13 and the aluminum substrate 11 are both provided with corresponding hole positions 3. The aluminum substrate 11 is designed with asymmetric threaded holes to lock with the power board 13, which can prevent the phenomenon of reverse installation and play a fool-proof role, greatly reducing.

The insulating column 162 is white, which avoids the situation where the pressing plate screw 163 and the three-phase AC aluminum column 16 are electrically conductive, and is safer to use.

[0027] As a specific technical solution of this embodiment, a circle of groove is provided at the bottom of the plastic cover 12 and a waterproof ring 19 is provided inside the groove. The bottom of the waterproof ring 19 contacts the top of the aluminum substrate 11. The setting of the waterproof ring 19 ensures the sealing of the connection between the plastic cover 12 and the aluminum substrate 11. The waterproof ring 19 is arranged inside the groove, which is not easy to shake or deviate, and is more stable to use.

[0028] As a specific technical solution of this embodiment, the top of the plastic cover 12 is provided with an AC aluminum column hole 125 corresponding to the three-phase AC aluminum column 16 and a DC aluminum column hole 124 corresponding to the DC aluminum column 142. The AC aluminum column hole 125 and the DC aluminum column hole 124 are arranged with reasonable spacing control, which facilitates users to perform plugging and unplugging and power connection operations.

A breathable valve 122 and a silicone waterproof ring 123 and a safety fixing hole 126 are also arranged on the top of the plastic cover 12. The safety fixing hole 126 is used to insert a screw to lock the safety 127. Since the plastic cover 12 and the aluminum substrate 11 adopt a sealing design, the gas inside the plastic cover 12 can be discharged through the breathable valve 122.

[0031] As a specific technical solution of this embodiment, at least one magnetic ring 131 is welded on the top of the power board 13 , and a communication connector 151 with one end extending to one side of the plastic cover 12 is welded on one side of the control board 15 .

[0033] In summary, in the forklift controller, the aluminum substrate 11 component can be used as a mounting structure and can also dissipate heat in a large area. The power board 13 is in contact with the aluminum substrate 11 through thermal grease, which solves the problem of power board 13 malfunctioning due to high heat. The setting of the insurance 127 plays a protective function in case of current overload to reduce product damage. The use of screws to fix the components makes disassembly more convenient and flexible.
