[0013] Referring to Figures 1-6 The vehicle controller shown, the housing 10 is a flat square box surrounded by the bottom plate 11, the top plate 12, the left side plate 13, the right side plate 14 and the rear side plate 15 opposite to each other, the area of the bottom plate 11 and the top plate 12 is larger than that of the left side plate 13 and the right side plate 14, and the housing opening opposite to the rear side plate 15 is covered by the cover plate 20, the cover plate 20 is detachably connected with the housing 10, the left side plate 13 and the right side plate 14 are in clamping groove type clamping cooperation with the opposite plate edges of the circuit board 50, and the groove length direction is consistent with the depth direction of the housing cavity, the cover plate 20 has a hole for exposing the wiring port 40 provided on the circuit board 50, and the circuit board 50 is parallel to the bottom plate 11 and the top plate 12 and arranged close to the bottom plate 11 or the top plate 12, and the top surface of the wiring port 40 is in abutting cooperation with the inner side surface of the top plate 12.

[0014] In the above scheme, the left side plate 13 and the right side plate 14 of the housing 10 are respectively provided with connecting lugs A for fixing the housing 10. In addition to the wiring port 40, the circuit board 50 is also provided with electronic components such as capacitors, in order to ensure that the above-mentioned electronic components do not collide with the housing 10, the spacing between the bottom plate 11 and the top plate 12 is in a free state to ensure that the electronic components on the circuit board 50 are not in contact with the bottom plate 11 and the top plate 12. The clamping groove type clamping cooperation between the circuit board 50 and the left side plate 13 and the right side plate 14 and the abutting cooperation between the top surface of the wiring port 40 and the inner side surface of the top plate 12, both of which cooperate to limit the circuit board 50 in the housing 10, so that the circuit board 50 will not shake in the housing 10 due to the bumping and vibration of the vehicle; in addition, by means of the abutting cooperation between the top surface of the wiring port 40 and the inner side surface of the top plate 12, the original inward deformation of the top plate 12 at the housing opening due to injection molding can be corrected, which makes the shape of the housing opening return to a square shape, so as to facilitate the assembly of the cover plate 20.

[0015] The wiring port 40 is located on the edge of the circuit board 50 adjacent to the plate surface of the cover plate 20, and in the assembly process of the vehicle controller, the plate edge of the circuit board 50 far from the wiring port 40 is first pushed into the cavity of the box body 10 by a mechanical arm and is respectively matched with the clamping groove of the left side plate 13 and the right side plate 14, and before the wiring port 40 contacts the top plate 12, the displacement process of the circuit board 50 in the cavity of the box body 10 is relatively smooth; at the end of the stroke of the circuit board 50, the top surface of the wiring port 40 abuts against the inner side surface of the top plate 12, so that the circuit board 50 is limited in the direction perpendicular to the plate surface thereof. In the above process, only one pushing action of the mechanical arm on the circuit board 50 is required to complete the assembly of the circuit board 50, and the circuit board 50 will not be damaged.

[0016] More specifically, the slot 30 provided on the left side plate 13 and the right side plate 14 is arranged opposite to the plate edge of the circuit board 50 to form a clamping groove matching, and the slot width of the slot 30 is consistent with the thickness of the circuit board 50 or slightly larger than the thickness of the circuit board 50. The former can limit the circuit board 50 in the direction perpendicular to the plate surface thereof by the slot 30, and the latter can reduce the assembly difficulty of the circuit board 50, that is, the displacement process of the circuit board 50 in the cavity of the box body 10 is more smooth, thereby reducing the manufacturing precision requirement of the slot width of the slot 30.

[0017] Preferably, as shown in Figure 4 the slot width of the slot 30 near the cover plate 20 side is greater than the slot width of the slot 30 located in the middle section of the box cavity. In other words, the two slot walls of the slot end of the slot 30 near the cover plate 20 side are in the shape of a flared horn, and the horn mouth faces the cover plate 20 side. The above scheme can make the plate edge of the circuit board 50 more easily embedded in the slot cavity of the slot 30 during assembly, further reducing the assembly difficulty of the circuit board 50.

[0018] In order to facilitate the control of the pressure generated when the wiring port 40 abuts against the top plate 12, the top surface of the wiring port 40 is provided with a thin piece 41 protruding towards the top plate 12, and the position of the thin piece 41 on the top surface of the wiring port 40 is near the box opening of the cover plate 20 side. The thin piece 41 can also be understood as a wedge-shaped protrusion with a low inner end and a high outer end, and preferably the wedge-shaped surface is located in the middle section and the outer end is a flat surface.

[0019] During the assembly process of the circuit board 50, after the wiring port 40 moves with the circuit board 50 and abuts against the top plate 12, the thin piece 41 at the top of the wiring port 40 can lift the top plate 12, reducing the curvature of the plate surface of the top plate 12, and as much as possible to restore the shape of the box opening to a square shape, facilitating the subsequent installation of the cover plate 20. According to the thickness of the thin piece 41, the curvature of the top plate 12 lifted by the top surface of the wiring port 40 can be determined, making the assembly process easier to control.

[0020] Preferably, the inner side of the top plate 12 is provided with a reinforcing rib 111 protruding towards the cavity of the box body 10, the lengthwise direction of the reinforcing rib 111 is parallel to the plate surface of the left side plate 13 or the right side plate 14, and the top surface of the wiring port 40 is provided with a recess 42 which is fitted with the reinforcing rib 111. The fitting of the recess 42 and the reinforcing rib 111 can limit the assembly stroke of the circuit board 50, further improving the stability of the assembly.

[0021] More specifically, the box cover plate 20 is provided with a clamping jaw 21 extending into the cavity of the box body 10, and the bottom plate 11 and the top plate 12 are respectively provided with a clamping hole 12 which is clamped and fitted with the tail end of the clamping jaw 21. The cross section of each pair of clamping jaws 21 on the box cover plate 20 is in the shape of an "eight". The assembly process of the box cover plate 20 is after the assembly process of the circuit board 50, the clamping jaw 21 is elastic, facilitating the clamping and fitting of the tail end of the clamping jaw 21 with the clamping hole 12. The distance between the inclined top of the clamping jaw 21 on the opposite side in the free state before assembly is slightly smaller than the interval in the short diameter direction of the box opening.
