DESCRIPTION OF THE PREFERRED EMBODIMENTS
Figure 1 shows a preferred embodiment of the present invention. Figure 1 embodies a housing 10 of a vehicle instrument cluster. The housing having a front sheet cover 20 and a back sheet cover 30. The front sheet cover 20 and the back sheet cover 30 are connected by and are integrally formed with at least one arm portion 40. When in use the front sheet cover 20 and the back sheet cover 30 is arranged to be substantially parallel to each other to sandwich the vehicle instrument cluster. The at least one arm portion 40 connects the front sheet cover 20 and the back sheet cover 30 which is arranged to be substantially perpendicular to the two covers.
The housing is prepared by simply folding a thin sheet of a blank provided with a plurality of dielines defining the front sheet cover 20, back sheet cover 30 and the at least one arm portions 40. The thin sheet can be made of any flexible and light- weighted material, for example low density polymers which are non-expensive, extremely light weight, flexible and are relatively easy and cheap to process. The low density polymers can be thermoplastic or thermosetting polymers. The sheet can be prepared by die stamping or molding. The sheet can be prepared by optical grade polymers adaptable to tailor light transmission for decorative and functional purposes. Alternatively, they can also be opaque or reflective to allow light reflection. They can be non-conductive for insulating purpose, which reduces the risk of electrostatic discharge of the instrument cluster, especially from the back portion of the instrument cluster where the printed circuit board (PCB) is usually exposed. This also helps improving the electromagnetic compatibility performance of the instrument cluster.
Figure 2 shows a sketch of a blank 100 of the housing 10 or an unfolded housing. In Figure 2, the solid dielines 120 represent cutlines while the broken dielines 140, 160, 180 and 200 represent foldlines. The foldlines 140 and/or 160 delineates the front sheet cover 20 and the at least one arm portion 40, while the foldlines 200 and/or 180 delineates the back sheet cover 30 and the at least one arm portion 40. The foldlines can be marked by folding, creasing, perforating, compressing or scoring of the sheet depending on the type of the marking machines available. The foldlines are located at the junctions between the sheet covers 20, 30 and the at least one arm portions 40. To assemble the blank 100 into a housing 10 for use, the front sheet cover 20 and the back sheet cover 30 are folded about the foldlines at the junctions to surround an instrument cluster, with the front sheet cover 20 covering a front portion of the instrument cluster, and the back sheet cover 30 covering a back portion of the instrument cluster. More specifically, the front sheet cover 20 is folded about the broken dielines 140 and/or 160 so that the front sheet cover 20 lies at a plane being substantially perpendicular to the at least one arm portion 40; and the back sheet cover 30 is folded about the broken dielines 200 and/or 180 so that the back sheet cover 30 lies at a plane being substantially perpendicular to the at least one arm portion 40 and being substantially parallel to the front sheet cover 20.
The at least one arm portion 40 of the housing may further comprise at least one shoulder portion 220 defined by the broken dielines 140 and 160, and/or the broken dielines 200 and 180. The shoulder portion 220 serves as a transition region when the at least one arm portion 40 join at the front sheet cover 20 and/or the back sheet cover 40. The shoulder portion 220 can be a beveled surface or a round surface with curved radius. Alternatively, the shoulder portion 220 can be a single edge joining the front sheet cover 20 and the arm portion 40, and/or the back sheet cover 30 and the arm portion 40.
Figures 3 and 4 show the housing 10 in its in use condition, i.e. with the housing 10 surrounding and encasing the instrument cluster showing the top sheet cover 20 (Figure 3) and the back sheet cover 30 (Figure 4) of the housing 10. This allows a very simple and user-friendly assembly of the instrument cluster with the housing, with significantly less tools or instruments required, and the number of steps and procedure of assembly can be much reduced and simplified.
The front sheet cover 20 consists of at least one indication means 60, for example, a gauge, an electronic device or a signalling device. The gauges can be in the form of a speedometer, tachometer, or meter indicating fuel-level, oil pressure, oil temperature or tire pressure etc. The gauges are marked with numbers and/or graduations as indicia, which can be printed onto the front sheet cover 20. The gauges can also be illuminated by a lighting device of the instrument cluster. The numbers and/or graduations can also be provided in the form of recesses or protrusions which are integrally molded with the housing 10. Alternatively, the gauge can be a digital device comprising a digital display such as a liquid crystal display integrally molded into the front sheet cover 20 of the housing 10. Similarly, the signally device can be any translucent screens integrally molded into the front sheet cover 20, and consequently illuminated by an illuminating means such as a laser light source, a focused light-emitting diode (LED) light source, or other kind of light sources provided on the instrument cluster. The front sheet cover 20 may also consists of at least one opening 80 adapted to connecting at least one pointer 90 to the instrument cluster for an electromechanical movement. The pointer 90 is connectable to, for example, a motor controller, such as a stepper motor, of the instrument cluster by means of a shaft. The pointer 90 is rotatable to sweep angularly across the gauge. The pointer 90 can also be virtually formed such as by electrical means in the form of an illuminated pointer provided by the digital device, provided that the digital device is integrally molded into the front sheet cover 20. The at least one opening 80 may also allow adaption of a lighting device, for example, a LED light source from the instrument cluster for illuminating or signalling purpose. Furthermore, the at least one opening 80 may also adapted to allow operation of other components of the instrument cluster by the driver such as a reset knob or switches or buttons to serve other functions.
The back sheet cover 30 also consists of at least one opening 80 adaptable to electrically connect the instrument cluster to a vehicle. As shown in Figure 4, the openings 80 can also be provided to adapt to at least one fixing means of the instrument cluster to hold together the housing and the encased instrument cluster. Alternatively, the back sheet cover 30 can also be provided with at least one fastening means (not shown). The at least one fastening means can be integrally formed with the housing. In another embodiment, the at least one fastening means can also be formed separately, and is releasably engageable to the housing. The at least one fastening means is adaptable to fasten said housing with the vehicle instrument cluster or the vehicle dash board. The same arrangement can also be provided on the front sheet cover 20 instead of the back sheet cover 30 to serve similar purpose. The fastening means can be in the form of clips, snap-fit couplings or any fasteners available in this field that a skilled person would consider suitable. In addition, molding or printing of brand name or company label of the instrument cluster can also be arranged on the back sheet cover 30 of the housing 10.
The housing 10 can also be molded to provide additional indentations or recesses, or protrusions to allow adaption of the encased instrument cluster to other components of the vehicle dash board. The at least one opening 80 of the housing 10 can also be provided to allow adaption to other components of the vehicle dash board.
It should be understood that the present invention should not be limited to the application in vehicle instrument cluster. A person skilled in the art should understand that the present invention can be arranged in any kind of instruments or instrument clusters.
It should also be understood that the above only illustrates and describes examples whereby the present invention may be carried out, and that modifications and/or alterations may be made thereto without departing from the spirit of the invention. Certain features of the invention, which are, for clarity, described in the context of separate embodiments, may also be provided in combination in a single embodiment. Conversely, various features of the invention which are, for brevity, described in the context of a single embodiment, may also be provided or separately or in any suitable subcombination.
