DETAILED DESCRIPTION

[0016] Embodiment 1

[0017] As Figs. 1-3The diagram illustrates a highly integrated controller structure, comprising: a housing 1, a circuit board 2, and a middle housing communication pin 3. The housing 1 is divided from top to bottom into an upper housing 11, a middle housing 12, and a lower housing 13. The upper housing 11 and the middle housing 12 form a first-layer circuit board mounting cavity, and the middle housing 12 and the lower housing 13 form a second-layer circuit board mounting cavity. The circuit board 2 includes: a first circuit board 21, a second circuit board 22, and a third circuit board 23. The first circuit board 21 and the second circuit board 22 are both disposed in the first-layer circuit board mounting cavity, which is divided into two independent cavities for separately mounting the first circuit board 21 and the second circuit board 22. The third circuit board 23 is disposed in the second-layer circuit board mounting cavity. The middle housing communication pin 3 is located below the middle housing 12 and connects the first circuit board 21, the second circuit board 22, and the third circuit board 23 for communication. By integrating the three controllers and communicating through internal pins, the number of connection pins is reduced while improving communication speed and reliability. It also facilitates the arrangement of vehicle wiring harnesses, improves the overall strength of the product against damage, and ensures that even if one controller fails, the other two controllers can still work normally.

[0018] like Fig. 2 The diagram shows a highly integrated controller structure in which the upper housing 11 and the middle housing 12 are sealed by a first sealing ring 4, and the middle housing 12 and the lower housing 13 are sealed by a second sealing ring 5.

Fig. 2 The diagram shows a highly integrated controller structure, in which a mounting port 121 is provided on one side of the middle housing 12 and the lower housing 13, and a connector 6 is mounted on one side of the third circuit board 23. The connector 6 protrudes from the mounting port 121, and the shape of the mounting port 121 matches that of the connector 6.

[0021] In this embodiment, each of the first and second circuit board mounting cavities includes, but is not limited to, one circuit board 2. This reduces the number of components, thereby reducing controller costs and decreasing the vehicle-side mounting area, while also facilitating vehicle-mounted layout and installation.
