[0015] The utility model will be further described in combination with the drawings.

[0016] Referring to Figure 1 , the utility model relates to an ECU structure for special abuse road conditions of off-road vehicles, including ECU cover, inductor, connecting pin needle, the inside of ECU cover 1 is provided with inductor 2, connecting pin needle 3, the surface of inductor 2 has the inductor pin needle 21 of extension, connecting pin needle 3 is located in the side of inductor pin needle 21 facing away from inductor 2, connecting pin needle 3 is the integral type bending structure of vertical connecting surface 31, bottom surface 32, bottom surface 32 is fixed with ECU cover 1, the back of vertical connecting surface 31 is plane structure, plane structure is welded and fixed with the outside of inductor pin needle 21, and plane structure increases the welding contact area of connecting pin needle 3 and inductor pin needle 21, thereby increasing effective welding area, increasing the pull-off force of connecting pin needle 3 and inductor pin needle 21, and improving welding strength.

[0017] Referring to Figure 3The integrated bending structure is stamping bending, and the bending angle of the integrated bending structure is greater than 90°. The back surface of the vertical connecting surface 31 is a surface facing away from the bottom surface 32. Since it is an integrated bending structure, the connecting pin needle 3 itself has stress, which moves the vertical connecting surface 31 away from the bottom surface 32, and when the bottom surface 32 is fixed to the ECU cover 1, the stress makes the back surface of the vertical connecting surface 31 close to the inductor pin needle 21, so that the connecting pin needle 3 is more tightly fitted with the inductor pin needle 21, further increasing the pull-out force.

[0018] The ECU cover 1 is internally provided with a support 4 supporting the inductor pin needle 21.

[0019] The ECU cover 1 is internally provided with an inductor mounting groove 11, the bottom of the inductor 2 is located in the inductor mounting groove 11, and the gap between the inductor 2 and the inductor mounting groove 11 is filled with fixing glue 5, which is beneficial to reduce the influence of the inductor 2 on the vibration and impact transmitted from the chassis and the pull rod, and avoid resonance. The effect of avoiding resonance can be further optimized by increasing the amount of fixing glue 5.
