Description
Technical field
The utility model belongs to electric vehicle engineering field, is specifically related to the vehicle-mounted wire harness protection pipe of a kind of electric automobile.
Background technology
Wire harness is the connecting part connecting each electric equipment in circuit, by insulating sleeve, and the compositions such as binding post, wire and insulating wrapping material.
At present, the electronic system of vehicle has become the primary study object of vehicle technology development, and connect each electronic equipment, element the span of wire harness very large, under this just means that the different piece of same group of wire harness is probably in multiple different service condition, such as: car load vibrations, vehicle localized hyperthermia and the service condition such as low temperature, peripheral component Dynamic wear.
Existing wire harness protection pipe is simply formed by single material usually, and harness cover is contained in protection tube, the similar general reliability of wire harness protection pipe and fail safe poor, under severe service condition, easily damage, so cause car accident.
Therefore, need a kind of reliability and the higher wire harness protection pipe of fail safe.
Utility model content
Utility model object: for above-mentioned prior art Problems existing and deficiency, the purpose of this utility model is to provide the vehicle-mounted wire harness protection pipe of a kind of electric automobile, reliability and fail safe more excellent.
Technical scheme: the utility model discloses the vehicle-mounted wire harness protection pipe of a kind of electric automobile, comprise metal tube and the pipe joint being positioned at metal tube two, described pipe joint diameter is greater than metal tube diameter, and described metal tube sidewall is evenly distributed with discharge orifice.
To the wire harness of the regional area or part that have mechanical wounding, this wire harness is successively through pipe joint and metal tube, and be fixed by two ends pipe joint, metal tube is protected wire harness mechanical damage position, increases the fail safe of wire harness.
As further optimization of the present utility model, metal tube described in the utility model is coating steel pipe.
As further optimization of the present utility model, beam diameter described in the utility model is not more than 0.3 with the ratio of metal tube internal diameter.
As further optimization of the present utility model, metal tube sidewall described in the utility model is at least provided with 2 discharge orifices, place, owing to considering that wire harness meets the situations such as air ponding, sets up discharge orifice.
As further optimization of the present utility model, between discharge orifice described in the utility model and discharge orifice, be spaced apart 0.4-0.6mm.
As further optimization of the present utility model, between discharge orifice described in the utility model and discharge orifice, be spaced apart 0.5mm.
As further optimization of the present utility model, pipe joint described in the utility model is fillet structure, in fixed beam process, ensures operating personnel's handling safety.
Beneficial effect: the utility model compared with prior art; have the following advantages: the utility model carries out rationally effective protection to the wire harness for the regional area having mechanical damage; prevent the short circuit that electrical damage causes; and the utility model is according to the practical service environment of wire harness, sets up discharge orifice, ensure that wire harness still can receive good protection when suffering air or ponding; the utility model structure is simple; production cost is low, applied range, has good economic benefit.
Accompanying drawing explanation
