Description

Technical Field

[0001] The utility model relates to a screw locking device for a domain controller mounting bracket, belonging to the field of automobile domain controllers. Background Art

[0002] An automotive domain controller is a high-performance computing unit responsible for managing and coordinating multiple electronic control units within a specific domain (such as the powertrain, chassis system, body electronics, and infotainment system). Both open ends of the domain controller are equipped with end caps, which are connected to the domain controller via multiple screws. One of the end caps is mounted with multiple wiring harnesses. This requires multiple screws to connect both end caps to the domain controller, which reduces assembly efficiency. Furthermore, the wiring harness affects the movement of the electric screwdriver, further impacting assembly efficiency. Therefore, a screw-locking device for the domain controller mounting bracket is needed to reduce screw usage. Utility Model Content

[0005] Furthermore, a small hole is provided on the side of the support ear facing the pull plate, and a rectangular groove is provided on the side of the pull plate facing away from the support ear. A round hole aligned with the small hole is provided in the rectangular groove, and a rectangular block is inserted in the rectangular groove. A screw hole aligned with the round hole is provided on one side of the rectangular block, and the screw passes through the small hole and the round hole and is threadedly connected in the screw hole.

[0006] Furthermore, both ends of the first end cover are recessed to form a first notch, and both ends of the second end cover are recessed to form a second notch. One end of the pull plate is connected and fixed in the first notch, and the pull plate passes through the second notch.

[0007] Furthermore, a first bracket plate is connected and fixed to one end of the first end cover, the first bracket plate and the first end cover are arranged perpendicular to each other, and a side surface of the first bracket plate is provided with a plurality of first waist holes for inserting bolts.

[0008] Furthermore, a second bracket plate is connected and fixed to one end of the second end cover, the second bracket plate and the second end cover are arranged perpendicular to each other, and a side surface of the second bracket plate is provided with a plurality of second waist holes for inserting bolts.

[0009] Furthermore, the outer surface of the domain controller is recessed to form a plurality of heat dissipation grooves, and the heat dissipation grooves are arranged parallel to the strip grooves.

[0010] Beneficial effects of the utility model:

[0011] 1. Fix one end of the pull plate in the first notch, and pass one end of the pull plate through the second notch, so as to conveniently confine the pull plate in the strip groove and make the pull plate in a hidden state.

Then fit the two ears on the second end cover with the two pull plates respectively. Then pass the screws through the ears and thread them into the pull plates. The first end cover and the second end cover can be installed on both ends of the domain controller with two screws, which reduces the number of screws used and keeps the screws away from the wiring harness, thereby improving assembly efficiency.

[0013] 3. Insert the rectangular block into the rectangular groove to assemble the rectangular block and the pull plate. Pass one end of the screw through the small hole and the round hole and screw it into the screw hole to complete the assembly of the support ear and the pull plate. When the screw hole is damaged, replace the rectangular block to avoid replacing the entire pull plate due to damage to the screw hole. BRIEF DESCRIPTION OF THE DRAWINGS
