The term "plurality" means two or more, unless otherwise clearly and specifically defined. In addition, in the description of the present invention, when it is said that a device is "connected" to another device, this includes not only direct connections, but also indirect connections through other elements.

[0030] It should be noted that, in the absence of conflict, the embodiments of the present invention and the features in different embodiments may be combined with each other.

[0031] Figure 3 The decomposition structure of the controller in the embodiment of the utility model is shown in FIG. Figure 4 The structure of the circuit board of the controller and the casting body in the embodiment of the utility model is schematically illustrated. Figure 5 The structure of the connector of the controller and the casting body in the embodiment of the utility model is schematically illustrated. Figure 6 The figure shows the assembly structure of the controller in the embodiment of the present utility model.

[0032] Combination Figures 3 to 6 As shown, the controller provided by the embodiment of the utility model includes a casting body 10, a circuit board 20 and a connector 30, wherein:

[0033] The connector 30 and the circuit board 20 are assembled on the same side of the casting body 10 , the connector 30 is assembled outside the casting body 10 , and the circuit board 20 is assembled inside the casting body 10 ;

[0034] When the circuit board 20 and the connector 30 are assembled with the casting body 10 , the soldering connection points 33 of the connector 30 are exposed in the cavity of the casting body 10 , and the soldering connection points 22 of the circuit board 20 extend out of the cavity of the casting body 10 and align with the soldering connection points 33 of the connector 30 .

[0035] The controller described above is configured such that the connector 30 and the circuit board 20 are assembled on the same side of the casting body 10. For example, as shown in the figure, the connector 30 and the circuit board 20 are assembled on the upper side of the casting body 10, so that the welding connection points 33 of the connector 30 and the welding connection points 22 of the circuit board 20 are exposed to the cavity of the casting body 10, thereby facilitating welding without being restricted by the cavity of the casting body 10. When the circuit board 20 and the connector 30 are assembled with the casting body 10, the welding connection points 33 of the connector 30 are exposed to the cavity of the casting body 10, and the welding connection points 22 of the circuit board 20 extend out of the cavity of the casting body 10 and are aligned with the welding connection points 33 of the connector 30. In this way, welding can be performed after the circuit board 20 and the connector 30 are assembled with the casting body 10, so that the assembly is stable.

[0036] Thus, the controller described above can overcome the problems of inconvenient welding and unreasonable assembly process existing in current controllers such as electronic steering control units by improving the structures and layouts of the casting body 10, the circuit board 20 and the connector 30.

[0037] In some embodiments, the controller further includes a casting cover 40 , and the connector 30 is assembled on the casting cover 40 ; as the casting cover 40 is assembled to the casting body 10 , the welding connection points 33 of the connector 30 are aligned and fit with the welding connection points 22 of the circuit board 20 .

[0038] The casting cover 40 is assembled with the casting body 10 to form a closed space to protect the internal circuit board 20. The connector 30 is assembled on the casting cover 40 to be assembled to the casting body 10 with the casting cover 40, and the welding connection point 33 of the connector 30 is aligned with the welding connection point 22 of the circuit board 20 for easy welding.

[0039] In some embodiments, the casting cover 40 is provided with a hollow portion 44 , and the welding connection point 33 of the connector 30 passes through the hollow portion 44 and extends out; as the casting cover 40 is assembled to the casting body 10 , the welding connection point 22 of the circuit board 20 passes through the hollow portion 44 and extends out.

[0040] The hollow portion 44 provides a space for the soldering points 33 of the connector 30 and the soldering points 22 of the circuit board 20 to be exposed in the cavity of the casting body 10 , and facilitates soldering of the soldering points 33 of the connector 30 and the soldering points 22 of the circuit board 20 .

[0041] In some embodiments, the controller further comprises: a protective cover 50, which covers the hollow portion 44. When the welding connection point 33 of the connector 30 and the welding connection point 22 of the circuit board 20 are welded, the protective cover 50 can be covered with the hollow portion 44 to protect the welding position.

[0042] In some embodiments, the protective cover 50 is sealed with the end surface of the hollow portion 44 through a sealing ring. In this way, a stable fit between the protective cover 50 and the end surface of the hollow portion 44 is achieved.

[0043] In some embodiments, the casting cover 40 is aligned and overlapped with the casting body 10 to form a closed space for protecting the internal circuit board 20. The casting cover 40 and the casting body 10 can also be fixedly connected by fasteners such as bolts.

[0044] In some embodiments, the soldering connection points 33 of the connector 30 and the soldering connection points 22 of the circuit board 20 are both formed as sheet soldering pins. The design of the sheet soldering pins can increase the contact area between the soldering connection points 33 of the connector 30 and the soldering connection points 22 of the circuit board 20, ensuring that the two are soldered firmly.

[0045] In some embodiments, the welding connection point 33 of the connector 30 and the welding connection point 22 of the circuit board 20 both include multiple pairs of sheet welding pins arranged at intervals. For example, the figure shows that the welding connection point 33 of the connector 30 includes four sheet welding pins, forming two pairs of sheet welding pins arranged at intervals (each pair of sheet welding pins includes a positive sheet welding pin and a negative sheet welding pin); correspondingly, the welding connection point 22 of the circuit board 20 also includes four sheet welding pins, forming two pairs of sheet welding pins arranged at intervals (each pair of sheet welding pins includes a positive sheet welding pin and a negative sheet welding pin). Multiple pairs of sheet welding pins form a redundant configuration, so that when the path corresponding to one pair of sheet welding pins fails, the paths corresponding to the remaining pairs of sheet welding pins can still work normally, thereby ensuring the reliability of the product.

[0046] Furthermore, in the above embodiments, the controller is an electronic steering control unit, which effectively overcomes the problems of inconvenient welding and unreasonable assembly process of the current electronic steering control unit.

[0047] Of course, the controller described in the present invention can also be other control devices of the automobile, and the problems of inconvenient welding and unreasonable assembly process of the current controller can be overcome by improving the structure and layout of the casting body 10, the circuit board 20 and the connector 30.

[0048] The above contents are further detailed descriptions of the present invention in combination with specific preferred implementations, and the specific implementation of the present invention cannot be considered to be limited to these descriptions. For ordinary technicians in the technical field to which the present invention belongs, several simple deductions or substitutions can be made without departing from the concept of the present invention, which should be regarded as falling within the protection scope of the present invention.
