Description

HUD pencil

Technical Field

The utility model relates to a pencil equipment field, in particular to HUD pencil.

Background

HUD-head up display, also called head-up display system, refers to a multifunctional instrument panel which is operated by a driver as a center and is a key component of a lane departure warning system. HUD can be with current driving information, for example speed of a motor vehicle, rotational speed, continuation of the journey, tire pressure etc to and interactive information such as navigation, multi-media, through windshield projection in the place ahead certain distance, form a virtual display screen. The driver need not turn round, bow to see traditional instrument desk or car machine at the driving in-process, just can obtain driving information through the place ahead projection image, makes the driver can put attention on the road in the place ahead always to can avoid the driving in-process because bow to see the instrument and lead to the occurence of failure, improve driving safety greatly. HUD was originally applied to airplanes, the technique was first applied to automobiles in 1988, bmw became the first automobile company in europe using HUD technique in 2003, and thereafter, general, gallow, honda, toyota, etc. were also equipped with HUD on under-flag models in succession. However, in a general view, the HUD application is still in a starting stage, the whole loading rate is not high, but the number of loaded enterprises is not small, and the function is increased by the side surface of the HUD application.

The pencil is the component that can not lack in the HUD system, and its effect is with power transmission and distribution to each part of HUD system to the inside data signal interactive transmission of guarantee HUD system, and the interactive transmission of data signal between HUD system and the external control ware. HUD pencil connection port should with the inside connection port phase-match of system, guarantee the reliability of connecting. When the system work, the HUD pencil can stably provide the power and guarantee that all kinds of data signal interaction can normally go on, can not influence the normal use of whole HUD system because of power unstability or signal receive the interference. In addition, the HUD wiring harness should be as lightweight as possible, and the connection interfaces should be as small as possible, in order to meet the overall size and weight requirements of the vehicle for the HUD system. Because of whole loading rate is lower, so do not have the research of specialty to the HUD pencil, nevertheless along with HUD's whole loading rate constantly promotes, urgently need a lightweight, the interference killing feature is strong, thermal-insulated effectual HUD pencil.

Disclosure of Invention

The utility model aims at overcoming the defect that prior art exists, providing a HUD pencil.

Realize the utility model discloses the technical scheme of purpose is: the utility model provides a HUD pencil, has that the connector inserts box, terminal, wire, the box is total two in the connector, and every connector inserts and is provided with five terminals side by side in the box, and two connectors insert the box in corresponding terminal and connect through a wire respectively.

Furthermore, the outer sides of the middle sections of the five wires are integrally wound with insulating wear-resistant adhesive tapes.

Furthermore, a shielding layer is sleeved between the five wires and the insulated wear-resistant adhesive tape.

Furthermore, a heat insulation layer is sleeved between the shielding layer and the insulating wear-resistant adhesive tape.

Furthermore, a tensile steel wire is arranged between the wires, and two ends of the tensile steel wire are respectively fixed on the two connector plug boxes.

Furthermore, a lead fixing block is arranged at the joint of the five leads and the connector plug box.

After the technical scheme is adopted, the utility model discloses following positive effect has:

(1) The utility model discloses a miniaturized design and the lightweight design of HUD pencil help the design that integrates of HUD system totality.

(2) The utility model discloses a shielding layer, insulating layer and tensile steel wire, the various data signal of guarantee HUD system can normally go on under the service environment of complicacy alternately, can not appear because of the pencil is connected unreliable, or the electrical property is unstable, causes the power and the signal of HUD system to receive the interference and influence normal use.
