Description

The present invention relates to an installation device for a motor vehicle. The invention furthermore relates to a system having such an installation device and a mounting means for installation in an installation space, in particular an installation space of an installation device, provided for front installation, of a motor vehicle.Such built-in devices are nowadays used in almost any motor vehicle for the installation of, for example, a chronograph unit, also referred to as a trip recorder.The dimensions of the built-in device are usually oriented here to DIN ISO 7736:1985-04, which also specifies possibilities for fastening the built-in device in the installation space of the motor vehicle. In this case, a lateral fastening of the built-in device in the installation space of the motor vehicle is preferably proposed, in which the built-in device has a housing with a holding element. The retaining element latches here into a corresponding cutout of a mounting means in the installation space of the motor vehicle, which serves for installing the installation device into the installation space of the motor vehicle. The built-in device is thus secured and held by the mounting means in the installation space of the motor vehicle against removal.The disadvantage of this is that in such built-in devices of the prior art, the holding element mounted on the housing is damaged when the built-in device is removed from the installation space of the motor vehicle and the holding means formed on the holding element is deformed in an uncontrolled manner. In this case, a removal tool abuts against the holding means or slides under the holding means, between the housing and the holding means, and deforms it, as a result of which removal of the installation device from the installation space is made more difficult or even impossible. The holding means is deformed so much that the built-in device clamps to the mounting means mounted in the installation space.Furthermore, problems arise when the built-in device is mounted again. The dimensions and tolerances to be observed of the built-in device, in particular of the retaining element mounted on the housing, are no longer observed due to deformation of the retaining means formed thereon. The built-in device can only be inserted into the installation space of the motor vehicle or the mounting means arranged in the installation space with difficulty.DE 103 57 799 A1 discloses an adapter system for installing an installation device into an installation space of an installation device provided for front installation in a motor vehicle. The adapter system comprises at least two separate sub-elements which are arranged on two opposite sides of the built-in device. Each partial element comprises the built-in device in a U-shaped manner.Furthermore, EP 1 225 095 A1 discloses an installation device to be mounted in an installation opening. The built-in device is fixedly connected on two opposite sides in each case to a retaining spring which in each case has at least one spring arm which has a latching nose which latches into a stationary contact edge. In addition to the latching lug, at least one resilient catch lug is provided, which, when the mounting device is moved out of the mounting opening, after the latching lug has been released, can engage with a steep catch surface in a form-fitting manner against a retaining surface.In addition, a holder for devices which can be inserted into a shaft in the region of a dashboard of a vehicle, having at least one latching spring which is arranged fixedly on the vehicle and engages with a latching nose into a cutout in a device housing, is known from DE 39 06 216 C1. The latching lug is bent back at its free end, which is situated at the front in the direction of travel of the vehicle and points downward, beyond the vertical in the opposite direction to the direction of travel.The object of the present invention is to provide an installation device of the type mentioned at the beginning with a housing and a holding element, which permits reliable and reliable assembly or disassembly of the installation device without the holding element or the holding means formed on the holding element being damaged or deformed. In addition, the object of the invention is to create a system with such an installation device and an installation means for installation in an installation space of a motor vehicle.The object is achieved according to the invention by the features of the independent claims. Advantageous embodiments can be gathered from the dependent claims.According to a first aspect of the present invention, an installation device for a motor vehicle has a cuboidal housing, wherein the housing has a retaining element on an outer side on two opposite sides of the housing. Each of the holding elements has a holding means in each case, wherein the respective holding means is fixedly connected to the housing in its elongate extent at a first end arranged in the installation direction in which the installation device is installed in the motor vehicle. The respective holding means is designed in such a way that the built-in device can be held firmly in the installed state in the motor vehicle by means of the two holding means. The housing has on the outer side on two opposite sides of the housing a respective recess with a respective bevel, wherein the respective recess is formed parallel to the installation direction and to the respective holding means. The respective recess is formed in such a way that the respective holding means can be accommodated in the respective recess in its elongate extent at a second end arranged counter to the installation direction, which is a free end, perpendicular to the installation direction and can be guided on the respective bevel.In the built-in device according to the invention, the technical configuration of a recess with a respective bevel on two opposite outer sides of the housing is particularly advantageous. As a result, during disassembly of the mounting device, the holding means of the holding element, which holding means each run parallel to the recess on the housing, can be accommodated in its elongate extent in the respective recess and can be guided on the slope formed on the recess. The holding means is hereby pressed into the respective recess in a controlled manner during disassembly by means of a removal tool. The holding means is not deformed in an uncontrolled manner, as a result of which the built-in device does not become caught and tilted when it is removed from the installation space or the mounting means arranged in the installation space. The built-in device can thus be properly guided out of the installation space during disassembly. The built-in device according to the invention can preferably be a chronograph unit or, more generally, an on-board unit for a motor vehicle, in particular a commercial vehicle.According to an advantageous embodiment of the invention, the respective slope formed on the housing has an angle α greater than 90°, preferably an angle range between 110° and 150°, perpendicularly from the housing counter to the installation direction, wherein the slope preferably has an angle of 135°.One advantage is that the respective holding means is accommodated in the respective recess in its elongate extent at a second end arranged counter to the installation direction, which is a free end, perpendicular to the installation direction and is guided at the respective bevel. As a result, the holding means is not pressed into the material of the housing in an uncontrolled manner during disassembly by means of the removal tool, as a result of which the housing and the holding means are damaged. By receiving the holding means in the recess and guiding the free end on the bevel, the holding means maintains its shape and does not deform so easily during disassembly, since the compressive forces acting on the holding means by the removal tool are transmitted to the bevel.According to an advantageous embodiment of the invention, the respective holding element has two holding means, wherein a first holding means and a second holding means are arranged parallel to one another.One advantage is that the built-in device has a firm and secure seat in the installation space of the motor vehicle. As a result, the built-in device is secured in the installation space against uncontrolled slipping out, for example in the event of an accident. Moreover, tilting of the built-in device in the installation space after assembly is prevented if the respective holding element or the respective first holding means and the respective second holding means latches with the mounting means arranged in the installation space. A further advantage is that the contact pressure forces acting between the holding means or the first holding means and the second holding means and the mounting means are distributed uniformly on the housing of the built-in device.According to an advantageous embodiment of the invention, the respective holding element is manufactured from a metal.One advantage is that a holding element made of metal is robust with respect to forces acting thereon and can be easily shaped and bent. This is advantageous in particular when compressive forces act on the holding element during assembly or disassembly by means of the removal tool. In addition, metal has high strength of the material. Compared to a holding element made of plastic, for example, the material has a slower fatigue and aging in the case of a holding element made of metal. A further advantage is that a holding element made of metal can be brought into any desired shape quickly and cost-effectively.According to an advantageous embodiment of the invention, the holding element is manufactured as a stamped and bent part.One advantage is that the holding element can be manufactured individually as a stamped and bent element according to the specifications and requirements of the respective technical requirements. A further advantage is that stamped and bent parts are quick, precise, cost-effective and energy-saving in production. Stamped and bent parts also offer high flexibility in the shape and configuration of the component to be produced and can be produced in a high number of pieces.According to an advantageous embodiment of the invention, the respective holding means of the respective holding element is designed to be elastically resilient in its elongate extent perpendicular to the installation direction.One advantage is that the holding means can be elastically deformed to a small extent under forces acting thereon, for example under pressure forces acting through the removal tool. No plastic deformation and deformation of the holding means occur when compressive forces are exerted on the holding means by the removal tool. In the case of elastic deformation, after the deformation, the holding means returns to its original state after the force acting on the holding means is removed. Thus, there is an advantage in that the holding means does not lose its shape under the action of forces and maintains its original initial shape. This ensures that the holding means performs its function as a holding element and securely locks the built-in device in the installed state.A further advantage is that the geometric shape of the holding means in its elongate extent increases the stability at the second end, the free end, of the holding means. This is preferably achieved by a radius at the transition to the second end of the holding means, whereby forces acting on the holding means, in particular compressive forces, are particularly well absorbed and the second end of the holding means is more dimensionally stable. The second end, the free end, of the holding means has a larger angle with respect to the horizontal of the holding element than the first end, the fixed end, of the holding means. The first end of the holding means thus has a smaller acute angle, so that the first end of the holding means is oriented flatter with respect to the second end of the holding means. The larger angle at the second end, the free end, of the holding means ensures that the function of the holding means is maintained even in the event of a misbeasy force effect during disassembly or assembly and the free end is not deformed. In the event of a mis-stress force, this force is preferably transmitted to the first end, the fixed end, of the holding means, whereby the second end, the free end, of the holding means is not deformed and retains its shape.According to an advantageous embodiment of the invention, the respective holding element is held on the housing in a form-fitting and / or force-fitting manner.In the preferred case, the respective holding element is connected in a form-fitting manner to a receiving element which is formed in each case on the outer side on two opposite sides of the housing. Alternatively or additionally, the respective holding element can be screwed in a force-fitting manner via the front side of the housing to a front panel arranged on the front side of the housing and thus held.One advantage is that a holding element connected to the housing can be easily replaced in the case of a positive or force-fit connection without the housing being damaged. Should the holding means formed on the holding element nevertheless be damaged during the assembly or disassembly of the built-in device, the holding element can be replaced quickly without the entire housing having to be replaced with the holding element.A further advantage is that in the case of a force-fit connection, the tensile or compressive forces acting on the holding element or holding means during assembly or disassembly are transmitted further from the holding means to the housing.According to an advantageous embodiment of the invention, the respective holding element forms an integral connection with the housing.In the preferred case, the housing and the holding element are manufactured in a single production process, for example an injection molding process, from a material, for example a plastic, and thus as a single-piece component. This has the advantage that an integral connection of the housing and the holding means is cost-efficient and time-efficient.Alternatively, for a one-piece connection during a manufacturing process of the housing, for example during an injection molding process, a holding element, for example made of metal, can be inserted into the injection mold for manufacturing the housing and cast with the housing and thus firmly connected. This has the advantage that further assembly steps and assembly means for connecting the holding element to the housing are omitted.According to an advantageous embodiment of the invention, the respective holding means has a latching nose in its elongate extent perpendicular to the installation direction, pointing away from the housing.An advantage is that the built-in device has a firm and secure seat in the installed state and the built-in device is not easily detachable in the installed state.A further advantage is that the contact pressure force for holding the built-in device in the installation space of the motor vehicle is increased by means of the latching lug of the respective holding means. In this case, the latching lug of the respective holding means latches into a respectively corresponding recess of the mounting means arranged in the installation space. The latching lug presses against a surface of the recess of the mounting means counter to the installation direction and thus ensures a firm seat of the installation device in the installation space of the motor vehicle.According to an advantageous embodiment of the invention, the holding means has, in its elongate extent perpendicular to the installation direction, a first latching lug and a second latching lug pointing away from the housing, wherein the first latching lug is formed on the holding means parallel to the second latching lug.One advantage is that the compressive forces acting on the built-in device in the installed state are distributed uniformly over the first latching nose and the second latching nose of the holding means, whereby no deformation of the holding means occurs. A further advantage is that the built-in device, in the installed state, has a fixed seat in the installation space of the motor vehicle. In addition, the parallel locking noses of the respective holding means serve to guide the removal tool during the dismantling of the built-in device. This has the advantage that the dismantling tool is guided between the two latching noses of the respective holding means and does not slide or can slide off the holding means.According to an advantageous embodiment of the invention, the built-in device is characterized in that at least one latching nose has at least one step for each holding means.One advantage is that the built-in device can latch and be held in different positions in the mounting means arranged in the installation space in the installed state. As a result, the pressing force between the latching nose formed on the holding means or the step formed on the latching nose and the mounting means can be increased. In addition, tolerances between the holding means and the mounting means can be compensated, as a result of which the built-in device can be properly mounted and held in the installation space of the motor vehicle.A further advantage is that the step formed ensures that the latching nose of the holding means continues to latch in the mounting means even in the event of a slight deformation of the holding means and securely holds the built-in device in the installed state.According to an advantageous embodiment of the invention, the holding means has, in its elongate extent, a tab deflected away from the housing perpendicularly to the installation direction.One advantage is that a greater compressive force can be exerted on the holding means by the tab formed on the holding means, whereby the holding means, which is latched to the mounting means, can be easily released from one another and the built-in device can be pulled out of the installation space of the motor vehicle counter to the installation direction.By means of the removal tool, the holding means is pressed in a controlled manner via the tab into the recess formed on the outer side of the housing. In this case, the second end, the free end, of the holding means is preferably pressed into the recess of the housing in its elongate extent perpendicularly to the installation direction. The forces acting on the tab and thus on the holding means by the removal tool are also transmitted to the housing via the first end, the fixed end, which is connected to the housing. This ensures that the holding means does not deform in an uncontrolled manner and that the forces introduced concentrate on the fixed end of the holding means.According to an advantageous embodiment of the invention, the housing is made of a plastic.As a preferred plastic, for example, ABS (acrylonitrile-butadiene-styrene copolymer), polycarbonate, polyamide, polyester or polyoxymethylene is used for the housing. These plastics have a good mechanical property during processing.One advantage is that plastic is easy to process, whereby the housing can be manufactured in any desired shape. In addition, the production of a housing made of plastic is cost-effective. In the case of a housing made of plastic, a recess with a slope can be produced particularly easily, for example by means of an injection molding method, during a single production step.The aforementioned features and advantages may also apply to the system described below.According to a second aspect of the present invention, a system is provided, comprising an installation device and an assembly means, wherein the assembly means is configured to hold the installation device in an installation space of a motor vehicle.According to an advantageous embodiment of the invention, the latching nose of the holding means latches into a corresponding recess of the mounting means.One advantage is that the built-in device and the mounting means are designed in such a way that the system is held in an installation space of a motor vehicle and is secured against unauthorized disassembly or extraction. In the locked state, the latching lug of the holding means presses against a surface of a recess of the mounting means and reliably holds the built-in device in the installation space of the motor vehicle.The built-in device according to the invention is used, for example, in a motor vehicle, preferably for mounting as a chronograph unit in a heavy goods vehicle. Accordingly, the system according to the invention is preferably used in an installed state in a motor vehicle, in particular a lorry.Advantageous refinements of the invention also result from the features of the following description and of the figures.To better understand the principles of the present invention, embodiments of the invention are explained in more detail below with reference to the figures. Identical reference numerals are used in the figures for identical or identically acting elements and are not necessarily described again for each figure. It is to be understood that the invention is not limited to the illustrated embodiments and that the described features may be combined or modified without departing from the scope of the invention as defined in the appended claims.They are shown in schematic, schematic diagram: FIG. 1 shows a perspective view of an installation device without a retaining element from the front, FIG. 2 shows a perspective view of the built-in device shown in FIG. 1 without a holding element from behind, FIG. 3 shows a perspective view of a holding element for holding the built-in device, FIG. 4 shows a right-hand view of the built-in device with a retaining element mounted on the housing of the built-in device, FIG. 5 is a perspective view with a recess formed on the mounting device and a bevel for receiving and guiding the holding means shown in FIG. 3, FIG. 6 shows a perspective view of a mounting means from the front, FIG. 7 shows a vertical section through a system with a built-in device in the installed state FIG. 8 shows a system with an installation device and a mounting means.FIG. 1 shows a perspective view of an installation device 100 from the front. The built-in device 100 is shown in FIG. 1 after mounting a front panel 110 on a front side 215 of a housing 200 of the built-in device 100. The front panel 110 of the built-in device 100 closes the front side 215 of the housing 200 and is provided with various functional elements, which are not described in any more detail here. In the non-assembled state of the front panel 110 on the housing 200, for example, electronic components such as circuit boards can be inserted into the interior of the housing 200 via the front side 215 of the housing 200.The housing 200 of the paving apparatus 100 has an upper side 211, a lower side 212, a left side 213, a right side 214 and a rear side 216, which define a cuboidal outer contour of the paving apparatus 100. On two opposite outer sides of the housing 200, the left side 213 and the right side 214, the housing 200 has in each case two recesses 220, 230 each having a bevel 221, 231, wherein the respective two recesses 220, 230 are formed parallel to the installation direction X of the installation device 100. The respective bevel 221, 231 of the recess 220, 230 formed on the housing 200 extends perpendicularly Z to the respective side 214 of the housing 200 counter to the installation direction X of the installation device 100. In addition, the housing 200 has on the outer side, on the two opposite sides, the left side 213 and the right side 214, in each case a receiving element 280 for receiving and fixing a retaining element 300, which is not illustrated. The respective receiving element 280 is formed here parallel to the installation direction X on the outer side of the installation device and runs parallel to the recesses 220, 230 formed on the housing.Through-recesses 111 to 114 are formed in the front panel 110 of the mounting device 100, which serve for removing the mounting device 100 from an installation space of a motor vehicle. Here, a not-illustrated removing tool, for example, in the form of a wire, is passed through the through-holes 111 to 114 and the installation device 100 is detached from the mounting means 500 inserted in the installation space of the motor vehicle.In an embodiment which is not illustrated here and does not fall under the invention and which is also conceivable in principle here, the housing 200 has no recesses 220, 230 with a bevel 221, 231 on two opposite outer sides, the left side 213 and the right side 214 of the housing 200. As can be seen in FIG. 4, the holding element 300 is inserted into a receiving element 280 and fixed counter to the mounting direction X on the outer side of the housing 200. The respective holding means 310, 320 of the holding element 300 is guided in its elongate extent at a second end 312, 322 which is arranged counter to the installation direction X and is a free end, perpendicularly to the installation direction X, directly on the outer side of the housing 200.FIG. 2 serves for additional clarification and shows the built-in device described in FIG. 1 in a perspective view from behind. On the front side 215, the housing 200 has two recesses 240, 250 on the two opposite sides 213, 214. Via the recesses 240, 250 arranged on each side, the retaining element 300 from FIG. 3, which is not shown and is accommodated and fixed in the mounted state in the receiving element 280, for example on the right outer side 214 of the housing, can additionally be connected to the front panel 110 mounted on the front side 215 of the housing 200. For this purpose, as shown in FIGS. 4 and 5, a commercially available mounting means 600, for example a screw, is used.Furthermore, the housing 200 has two pins 242, 252 on the front side 215, on the two opposite sides 213, 214. By means of the pins 242, 252, the holding element 300 arranged on each side 213, 214 is held and centered during the assembly with the housing 200, so that the holding element 300 is arranged parallel to the recess 220, 221 formed on the housing. The pin can be manufactured integrally with the housing, for example, during an injection molding process. Corresponding to the through-recesses 111 to 114 described in FIG. 1 in the front panel 110 of the paving apparatus 100, the housing 200 has, on the front side 215, on the two opposite sides 213, 214, in each case two recesses 241, 251 which serve for guiding a removal mechanism, not shown. In this case, as shown in FIG. 1, a removal tool, not shown, is guided through the through-recesses 111, 112 in the front panel further through the recess 242, 252 on the front side 215 of the housing 200. The recesses 240, 241 and pins 242 formed on the left side 213 and the right side 214 of the housing 200 are arranged symmetrically here.The housing 200 has a holding element 300, not shown, for each side, the left side 213 and the right side 214.FIG. 3 shows an exemplary configuration of the holding element 300 in the non-assembled state with the housing 200, wherein the holding element 300 is constructed along a tongue 330 in mirror symmetry in the assembly direction X (axis of symmetry 400). The holding member 300 may be mounted and held on the outside of the housing 200, the left side 213, and the right side 214.As can be seen, the holding element 300 has a first holding means 310 and a second holding means 320. The first holding means 310 has, in its elongate extent in the mounting direction X, a first end 311, which is fixedly connected to the holding element 300, and a second end 312, which is free and movable. In this embodiment, the second end 312, the free end, of the holding means 310 is at a greater angle with respect to the horizontal of the holding element than the first end 311, the fixed end, of the holding means 310. The first end 311 of the holding means 310 thus has a smaller acute angle of 15°, so that the first end 311 of the holding means 310 is oriented flatter with respect to the second end 312 of the holding means 310. The second end 312 of the holding means has an angle of 35°.Furthermore, the first holding means 310 has, in its elongate extent, between the first end 311 and the second end 312, on its outer contour a first latching nose 313 and a second latching nose 315, wherein the first latching nose 313 is arranged parallel to the second latching nose 315 on the holding means 310. The two latching noses 313, 315 are each set up 90° in the elongate extension of the holding means 310.Each of the two latching noses 313, 315 has a step 314, 316 in each case. In an exemplary embodiment, each of the two stages 314, 316 includes two stages. The steps 314, 316 of the respective latching noses 313, 315 are designed in such a way that, as shown in FIG. 7, the holding element 300 latches with the latching noses 313, 315, 323, 325 respectively formed on the first holding means 310 and second holding means 320 or with the steps 314, 316, 324, 326 respectively formed on the latching noses with a respective recess 510, 511 corresponding in the mounting means 500.In its longitudinal extension, the holding means 310 is bent between the first end 311 and the second end 312. Due to the fact that the holding means 310 has a free end 312, the holding means 310 is designed to be elastically resilient in its elongate extent, as a result of which the holding means 310 can be released from the mounting means 500 again. For this purpose, for example, the first holding means 310 has, in its elongate extent, between the first latching lug 313 and the second latching lug 315, a tab 317 which is deflected perpendicularly to the installation direction X and by means of which the holding means 310 is released from the mounting means 500 during disassembly. In this case, a removal tool presses on the tab 317 and the first holding means 310 with the two latching noses 313, 315 is released from the recess 510 of the mounting means 500, not shown here.The second holding means 320, which is arranged parallel to the first holding means 310, has the same structure and the same function as the first holding means 310.Furthermore, FIG. 3 shows, counter to the installation direction X, an exemplary configuration of a first flange 340 and a second flange 350 on the holding element 300. The flanges 340, 350 are arranged to be used for mounting the holding member 300 to the outside of a housing 200 of an installer 100, as shown in FIGS. 4 and 5, and for connecting to a front panel 500 mounted on the front side of the housing 215.The first flange 340 has a recess 341, whereby the holding means 311 of the holding element 300 is connected to the housing 200 and the front panel 110 mounted on the front side of the housing 215. For this purpose, a mounting means 600, for example a screw, is used. Furthermore, the flange 340 has a recess 342, which serves for guiding the removal tool, not shown here. As shown in FIGS. 4 and 5, the removal tool can be guided through the through-recess 111 formed in the front panel further through the recess 241 corresponding to the front side of the housing. Subsequently, the removal tool is guided further on the outer side of the housing up to the holding means 311 of the holding element 300. The removal tool is guided between the two latching noses 313, 315 formed on the holding means 311 and presses on the tab 317, whereby the holding means 311 is released from the mounting means 500.The second flange 350 has a structure and function corresponding to the first flange 340. Each of the flanges 340, 350 has a further recess 343, 353, which serves for centering the holding element 300 with the respective pin 242, 252 formed on the housing, as can be seen in FIG. 2.Furthermore, FIG. 3 shows a tongue 330 with a tab in its elongate extension between the first holding means 310 and the second holding means 320. The tongue 330 extends parallel to the first holding means 310 and the second holding means 320. The holding element 300 can be inserted into a receiving element 280 and thus fixed by means of the tongue 330, as can be seen in FIG. 4, counter to the mounting direction X on the outer side of the housing 200.The holding element 300 has an axis of symmetry 400, as a result of which the first holding means 310 formed on the holding element 300 and the second holding means 320 are formed on the holding element 300 symmetrically with respect to one another. The same construction and the same mode of operation apply to the two holding means 310, 320. This also applies to the first flange 340 and the second flange 350 formed on the holding member 300.FIG. 4 shows the holding element 300 described in FIG. 3 in the mounted state on the right side 214 of the housing 200 of the built-in device 100. In an exemplary embodiment, the tongue 330 of the retaining element 300 is inserted and held in the receiving element 280 formed on the right 214 outer side of the housing 200, counter to the installation direction X. In addition, the holding element is connected to the housing 200 on the front side 215 by means of a mounting means 600, for example a screw, counter to the installation direction X, and the front panel 110 of the installation device 100 mounted on the housing 200 on the front side 215.
