Definitions
- the invention relates to a display device for displaying operating states with electrically controllable lighting elements fastened to a printed circuit board, a housing and a front plate which can be connected to the housing and on which the translucent areas assigned to the lighting elements are formed.
- optical and / or acoustic signal generators are provided for malfunction reporting, to indicate that critical operating states have been reached or to reach reserve values for consumables, in any case for certain basic functions of vehicles, machines or production systems, which are usually provided in front walls, in dashboards or display panels together with Operating and other display devices are integrated.
- Control system, the encoder, the signal processing electronics and the signal display means to be designed so that it is as simple as possible manufacture are inexpensive that the assembly and the subsequent exchange require neither special knowledge nor special devices and that a reliable function is guaranteed.
- the object of the present invention was to create a display device for displaying operating states which is characterized by particular simplicity and can be produced with little effort, but is reproducible, can be used in a variety of ways and is largely independent of the spatial conditions can be attached.
- the solution to the problem is characterized in that the housing of the display device is cup-shaped with a bottom and a circumferential wall, that light channels assigned to the lighting elements are formed on the inside of the tray on the bottom, that on the outside of the tray on the bottom a depression assigned to the front plate It is formed that the circuit board serves as a cover closing the rear of the housing and that latching means are formed on the peripheral wall of the circuit board.
- the main advantage of the display device consists in the fact that it consists of three structural units which can be produced and connected to one another in a simple manner and ultimately also permit mechanical assembly, and which are easily interchangeable. It is also advantageous that, due to its particularly flat dimensions, the display device can be attached to an instrument panel, a dashboard or the like in a largely spatially independent manner, as well as permanently assigned and preferably recessed or, with a corresponding housing design, can be installed flush with the front surface, the attachment also being easy for the user can be made and no screwing required.
- the display device can be designed for a large number of use cases only by different printing on the front plate and, if necessary, adapted on site to the present use case.
- the display device can be provided to display critical operating states between the wheel and axle of a vehicle, for example with regard to the brake pads, the brakes and / or wheel bearing temperatures, the wheel or axle loads or the tire pressures, but also with regard to the function of anti-lock and anti-slip systems, and to be displayed correctly in relation to the vehicle geometry.
- the display device can also be used to signal the working time limits, for example of the driver and front passenger of a vehicle, and to facilitate compliance with the prescribed breaks.
- the display device can of course also be used exclusively as a test device, for example in a motor vehicle workshop or by a vehicle fleet controller.
- the relevant lighting element intermittently and / or to give an acoustic signal, either continuously or after a certain time.
- strain relief for the flat cable used for the desired flat design is integrated directly into the printed circuit board and that, since the printed circuit board lies directly against the end faces of the light channels, the rest of the housing does not necessarily have to be dustproof.
- Show it 1 shows a front view of the display device according to the invention
- FIGURE 2 is an inside or rear view of the housing
- FIG. 3 shows a rear view of the display device according to FIG. 1,
- FIGURE 5 is a side view of the display device attached, for example, to a dashboard.
- the front view according to FIG. 1 shows a housing 1 with a front plate 2, which is designed as a self-adhesive, transparent film and is printed with a symbol graphic for, for example, a brake pad check.
- the symbol graphic shows a road train with a motor vehicle 3 and trailer or semi-trailer 4 as well as a direction arrow 5 with a three-axle vehicle corresponding to six unprinted and thus translucent areas assigned to the respective brakes, one of which is designated by 6.
- 7 designates a ribbon cable, by means of which the display device is linked to electronics used for processing and organizing the encoder signals.
- FIGURE 2 and the section of the housing 1 in FIGURE 4 show that the housing 1 is bowl-shaped and essentially consists of a bottom 8 and a peripheral wall 9. On the wall 9 inwardly facing locking lugs 10, 11, 12 and 13 are formed, while on the bottom 8 concentrically to through openings 14, which are arranged according to the symbol graphic, several approaches 15 are formed. Furthermore, supports 16 are provided in the corners of the housing, which are preferably each provided with a blind opening 17, in order to be able to fasten the display device by screwing on if necessary.
- FIGURES 3 and 4 show that the display device is closed on the back by a cover which is formed by a circuit board 18 laminated on one side.
- a circuit board 18 laminated on one side.
- inward-pointing light-emitting diodes - one is designated by 19 - are attached and an outward-facing hook band 20 is fastened, which together with a self-adhesive counterpart 21 serves for screwless fastening of the display device.
- two parallel slots 22 and 23 are formed in the circuit board 18, which together with the web 24 remaining between them form a clasp which serves as a strain relief for the ribbon cable 7 guided around the web 24.
- FIG. 3 on the basis of the number of cores of the ribbon cable 7, only a number of light-emitting diodes required for the application is provided and connected, ie an expansion is possible compared to this application.
- FIG. 4 shows the particularly simple assembly, i. H. the self-adhesive coated front panel 2 is placed in a recess 25 formed in the housing 1 and fastened by pressing; the circuit board 18 is latched to the housing.
- the circuit board 18 is supported on the lugs 15 and the supports 16, the end faces of which lie in a plane "a", and the light-emitting diodes 19 protrude into the through openings 14, which together with the lugs 15 form light channels.
- the sealing effect can be further improved in that a material with a certain elastomeric effect is used for the housing and, if necessary, suitable sealing lips are formed on the light channels.
- FIGURE 5 shows an arrangement example of the display device according to the invention, for example on a dashboard 26.
- a flush installation of the display device flush with the front surface is also conceivable.
