Description

Technical Field

[0001] The utility model relates to the technical field of engine electrical components, in particular to an engine electrical component fixing bracket. Background Art

[0002] The tractor engine is equipped with a variety of electrical components, such as ECU, relays, etc., which are used to assist in controlling the engine. The traditional way to fix electrical components is to set a suspended extension tube above the engine to fix the electrical bracket, and fix each electrical component such as ECU, relay, second fuse box, etc. to the electrical bracket with a bolt. During the driving of the tractor, the engine vibration frequency is too large. At the same time, due to the weak strength of the bracket itself, the large number of electrical components on the bracket, and the heavy weight, the electrical bracket and the suspended extension tube both vibrate greatly, and far exceed the standard vibration frequency of the electrical bracket. Under the continuous high temperature environment inside the engine, the risk of fatigue fracture and loosening of the electrical bracket and the extension tube increases greatly with the long-term use of the engine, which brings the risk of damage to the electrical components on the electrical bracket. At the same time, electrical components such as the engine post-processor are set next to the electrical bracket. If the electrical bracket is loose, there is also a risk of collision damage to electrical components such as the engine post-processor. Utility Model Content

In the installation state, the mounting position 3 is fixed on the engine, the first electrical fixing position 4 and the third electrical fixing position 6 are respectively fixed with fuse boxes, and the second electrical fixing position 5 is fixed with a relay 21.

[0035] Principle:

[0036] The fuse box includes a first fuse box 20 and a second fuse box 22, which are two different types of fuse boxes. The first electrical fixing position 4 is used to fix the first fuse box 20, and the third electrical fixing position 6 is used to fix the second fuse box 22. The second electrical fixing position 5 is used to fix the relay 21. The fuse box and the relay 21 are original electrical components on the engine and are also the engine electrical appliances to be fixed by the utility model, belonging to the prior art.

[0037] In the installation state, the mounting position 3 is attached to and fixed on one side of the engine, and the support plate 2 horizontally extends above the engine, only occupying a part of the space on one side of the engine and a small amount of space above, with small space occupation and no influence on the installation of original electrical components such as the EPU and the engine after-treatment device. By transferring smaller electrical components such as the relay 21 and the fuse box to the utility model, it is beneficial to reduce the load on the original electrical bracket, reduce the vibration amplitude of structures such as the suspended extension pipe, and avoid fatigue fracture. At the same time, the reinforcing rib 7 helps to improve the bearing capacity of the support plate 2, reduce vibration, and avoid the loosening of the mounting bolts of the relay 21 and the fuse box.
