[0022] Example

[0023] Combined with Figure 1-2 A vehicle compressor controller hardware platform system structure includes a controller housing 10, wherein an integrated circuit board 20, a copper bar module 30 and a heat sink 40 are sequentially arranged inside the controller housing 10, an opening is provided at one end of the controller housing 10, the copper bar module 30 is inserted into the integrated circuit board 20 through its own pins, and the heat sink 40 is installed to the open end of the controller housing 10, and the controller housing 10 and the heat sink 40 fixed to the open end of the controller housing 10 are fixedly matched to form a housing to fix the integrated circuit board 20 and the copper bar module 30 inside.

[0024] The controller housing 10 is provided with a compressor mounting position and mounting positions for high-voltage connectors and low-voltage connectors. The controller housing 10 needs to be installed on the compressor, so the controller housing 10 is provided with a structure for installation on the compressor, preferably a slot fitting mechanism or a threaded fitting mechanism. The high-voltage connector and the low-voltage connector are used to connect different high-voltage components and mortgage components, and are interfaces for the controller to control high-voltage equipment or mortgage equipment.

[0025] The integrated circuit board 20 includes a circuit board, a main chip, a drive circuit, a switching power supply, a communication circuit, and a current and voltage collection component. The integrated circuit board 20 is used to install a low-power control part. The integrated circuit board 20 is connected to the circuit connected through a low-voltage connector. The integrated circuit board 20 is a prefabricated circuit board. The electronic components installed on the circuit board can be replaced according to actual needs, and the circuit board is of universal design, which is convenient, fast and low cost.

[0026] The copper bar module is mainly composed of electronic components, three-phase connectors, copper bars and insulating rubber injection molding. Electronic components include common-mode inductors, electrolytic capacitors and insulated gate bipolar transistors. The pins of each component are electrically connected through copper bars. The copper bars have excellent conductivity and strong over-current capacity. The copper bars are molded by rubber injection molding of high-temperature resistant insulating materials, which plays the role of electrical safety insulation of each component and each copper bar, and can also play a fixing role. There are columns on each copper bar, which are inserted into the board accordingly. After welding, the electrical connection of the copper bar module, power device and semi-finished circuit board can be integrated.

[0027] The copper bar module 30 is used to install a high-power control part. The copper bar module 30 is connected to a line connected through a high-voltage connector. The copper bar module 30 can be adapted to compressors of different voltages by replacing electronic components.

[0028] Put the low-power control part on the circuit board and the high-power part on the copper bar module 30. In this way, we do not need to modify the circuit board for different customer models. We only need to select the power devices on the copper bar module 30 according to the battery voltage of the model and the power of the compressor, so as to achieve a platform design of the hardware. The platform is compatible with compressor models with a rated voltage range of 60V to 630V, and has a high degree of adaptability.

[0029] The copper bar module 30 is welded in the corresponding hole of the circuit board through the pins on the copper bar module 30, so that the copper bar module 30 and the circuit board form a control whole, which has a stable structure and is easy to use.

[0030] The insulated gate bipolar transistor is fixedly connected to the heat sink 40 to conduct heat to the power device. The heat sink 40 is provided with grooves for embedding components such as capacitors and inductors to fix the inductors and capacitors. After the heat sink 40 and the controller housing 10 form a controller housing, the electronic components on the circuit board 20 and the copper bar module 30 can be well fixed and protected.

[0031] When in use, it is only necessary to fix the controller housing 10, circuit board, copper bar module 30 and heat sink 40 to form a complete controller, and install the controller on the compressor body. The battery provides high-voltage input power to the controller power device through the high-voltage connector. The vehicle control performs CAN communication through the low-voltage connector to control the compressor operation, speed and fault feedback.

[0032] According to different customer needs, a platform design can be achieved. Only by replacing the power devices on the copper bar module 30, compressors with different voltage inputs and different power output requirements can be matched, so that cost reduction is effective and the development cycle is greatly shortened. At the same time, the production process can be universalized, the production process can be simplified, and production efficiency can be improved.

[0033] The above schematically describes the present invention and its implementation methods, which are not restrictive. The drawings show only one implementation method of the present invention, and the actual structure is not limited thereto. Therefore, if ordinary technicians in this field are inspired by it and design structural methods and embodiments similar to the technical solution without creativity without departing from the purpose of the present invention, they should all fall within the protection scope of the present invention.
