Technical Field

The invention is based on a device having an electronics unit and a housing.

Background

It is known to surround an electronics unit of an installation by means of a housing by casting or encapsulating the electronics unit with plastic.

Such devices usually have a solid housing which is produced from plastic, for example by means of an injection molding process. Housings made of metal are also known, which accordingly enclose the electronics unit. However, these metal housings may shield the wireless communication unit of the electronics unit.

Disclosure of Invention

The invention is based on a device having an electronics unit and a housing.

An electronics unit is understood here to mean an electronics unit having electronic components, for example a sensor unit and/or a processing unit and/or a memory element and/or a communication unit and/or a switching element.

One aspect of the invention is that the housing has at least a first housing part and a second housing part, which are configured and joined in such a way that the electronics unit is enclosed by the housing, wherein the first housing part and/or the second housing part is configured as a film.

Such a housing with at least one housing part configured as a film is generally referred to as a blister pack (blisterverpackangung).

It is advantageous here that the housing part formed as a film can be produced significantly more cost-effectively than a housing part produced, for example, by means of an injection molding process. The costs for the device can be reduced accordingly, wherein costs are understood to be manufacturing and material costs. Despite this low cost, the housing part configured as a film offers the possibility of protecting the electronics unit from undesired external influences, for example from contamination or moisture. This allows to achieve a protection level certification (international protection code) according to IP54 or higher.

In addition, the housing part formed as a film has a significantly lower weight than the injection-molded part, as a result of which, for example, the transport costs of the device can be reduced.

Films are understood to be the following: the object is configured such that the thickness of the object is many orders of magnitude smaller compared to its width and length.

In one embodiment of the device according to the invention, it is provided that the first housing part and/or the second housing part have at least one fastening element.

It is advantageous here that the device can be fixed to the object by means of a fixing element. The corresponding object may be, for example, a transport item.

The device according to the invention is configured such that the fastening element is configured as a wing-shaped element, which in particular projects outwards from the housing.

It is advantageous here that the fixing element is very easily accessible from the outside of the housing, wherein the fixing means are not shielded by other components of the device. This simplifies the fastening of the device to the respective object. Furthermore, the properties of the housing, such as stability and/or transparency, are not affected by the fixing element.

According to a configuration of the device according to the invention, at least one fixing element has at least one passage opening.

In this case, it is advantageous if the device can be screwed and/or nailed and/or screwed to the respective object, for example by means of a through opening, in order to fix the device to the object.

The configuration of the device according to the invention provides that the first housing part has a first region which is configured in such a way that the first housing part is more elastic within the first region than outside the first region.

It is advantageous here if the housing part is first bent in the elastic region when a force is applied from the outside. Corresponding functions of the device, for example, the actuation of a switching element of the electronics unit, which is arranged in the housing, can thereby be realized.

According to a configuration of the device according to the invention, the first housing part has a recess at least partially in the first region.

It is advantageous here that such a recess can influence the elasticity of the housing part accordingly. This makes it possible, for example, to move the region enclosed by the first region more easily. Furthermore, the recess can exhibit an optical boundary for a possible user, so that the user can recognize, for example, that a possible function of the device is integrated in the region surrounded by the respective recess.

The configuration of the device according to the invention provides that the thickness of the first housing part inside the first region is thinner than the thickness of the first housing part outside the first region. It is advantageous here for the thinner housing part to be more elastic than the thicker housing part.

The respective thickness of the first housing part in the first region is given in particular by the wall thickness of the groove, particularly preferably by the wall thickness of the base of the groove.

The configuration of the device according to the invention provides that the first housing part has at least one second region which is designed such that the stability of the first housing part is greater inside the second region than outside the second region, and in particular such that the third region has increased protection against mechanical influences compared to outside the third region.

It is advantageous here that the electronics unit inside the housing is particularly well protected, since the housing is less prone to bending when forces act from the outside. Furthermore, the housing thus has a particularly protected third region.

The configuration of the device according to the invention provides that the second region and the third region are part of the upper side of the first housing part, wherein the first housing part is arranged in the third region offset with respect to the second region in such a way towards the interior of the housing that the third region is at least partially surrounded by the higher second region.

It is advantageous here if the raised second region protects the third region from mechanical influences or such mechanical influences are less easily able to enter the third region. This makes it possible to protect the electronic components of the electronics unit, which are arranged in this region, on the one hand, and on the other hand, for example, also to arrange elements on the outside of the housing part in the third region, which elements can still be protected by the higher second region. Such an element may have, for example, a label and/or a QR code that may be used to identify the device.

According to a configuration of the device according to the invention, the electronics unit has at least one switching element, wherein the switching element is arranged in particular such that it is located below the third region in its actuating direction.

It is advantageous here that the switching element can transmit corresponding control commands from the user to the electronics unit of the device. The switching element can have a push button and/or a toggle switch, for example. In particular, the distance between the first housing part and the switching element can also be reduced by the lower third region, as a result of which a simpler actuation of the switching element is likewise possible. Furthermore, the risk of the switching element being unintentionally actuated can be reduced.

The configuration of the device according to the invention provides that the upper side of the switching element extends parallel to the upper side of the first housing part in the third region.

It is advantageous here that the switching element can be actuated as simply and reliably as possible.

According to a configuration of the device according to the invention, the second region of the first housing part has at least one edge, wherein the second region comprises in particular a side wall of the first housing part, wherein the edge extends in particular parallel to an upper edge of the side wall.

It is advantageous here if each additional edge increases the stability of the housing.

Here, the edge is understood as the lower line: in this line the two surfaces meet at an angle, wherein the angle can be chosen arbitrarily, but the angle must not be 0 °, 180 ° or a multiple of 180 °.

The configuration of the device according to the invention provides that the first housing part and/or the second housing part are substantially or partially optically transparent.

It is advantageous here if the optical radiation can exit from and/or enter into the interior of the housing. This results, for example, in the possible user being able to see into the housing. Information that can be output by the display element of the electronics unit can thus be sensed optically by the user, for example.

Optical transparency is understood here to mean that optical radiation can penetrate through the material. The optical radiation that can penetrate the material here has in particular a predefined wavelength range. It is also possible that radiation with any wavelength can penetrate the material.

According to a configuration of the device according to the invention, the film of the first housing part and/or of the second housing part is a plastic film, in particular of a biomaterial.

It is advantageous here that the plastic film does not electromagnetically shield possible communication units of the electronics unit. Furthermore, in the case of using biological materials, the device can also be used in fields where specific premises are made for the materials used. This can be the case in the food sector, for example, where the material must be non-toxic, for example.

The configuration of the device according to the invention provides that the first housing part and/or the second housing part have an adhesive material and in particular a single-sided or double-sided adhesive coating.

It is advantageous here if the housing parts can be adhesively connected to one another, for example. Such an adhesive connection is very simple and cost-effective to implement. A further advantage is that the electronics unit can be connected to one of the housing parts, for example by means of an adhesive material, or the housing part can be mounted on the object by means of an adhesive material, whereby a simple but stable fixing of the electronics unit or the device can be achieved. The film with the adhesive coating can be, for example, an adhesive tape.

The electronic unit is configured as a data logger according to a configuration of the device according to the invention.

The device according to the invention can be used advantageously for monitoring an object in that it is arranged in or on the object or in the surroundings of the object. For this purpose, the correspondingly configured electronics unit has, in particular, a sensor unit for sensing at least one ambient parameter acting on the object and a memory element for storing the sensed at least one ambient parameter. From the sensed and stored ambient parameters it can be verified, for example, whether the object has been properly processed during transport. For example, it can be checked in accordance with the configuration of the sensor unit whether the object has been subjected to an impact or has exceeded a threshold value for humidity and/or temperature.

The low weight of the housing compared to common housings also provides the following advantages: a smaller damping of external influences onto the electronics unit and thus a smaller influence of the sensing of the environmental parameter acting on the object is achieved.

Detailed Description

Fig. 1 shows a perspective view of a first embodiment of the device according to the invention.

There is shown a device 10 having a housing 30.

The housing 30 comprises a first housing part 31 and a second housing part 32, wherein the second housing part 32 is not visible here, since it is covered by the first housing part 31. The first housing part 31 has two fixing elements 40. The fastening element 40 is configured here as a wing-shaped element and projects outwards from the housing 30. Furthermore, each fastening element 40 has a plurality of openings 41, which are configured, for example, as holes. The first housing part 31 also has a first region 51, a second region 52 and a third region 53, which are explained in more detail in fig. 2 and 3 described below.

Fig. 2 shows a first cross section of a first embodiment of the device according to the invention according to fig. 1.

The cross-sectional plane includes the line of intersection a shown in fig. 1 and extends through the apparatus 10 perpendicular to the line of intersection a, which is indicated by the double arrow a 1.

In addition to the housing 30 comprising the first housing part 31 and the second housing part 32, the device 10 comprises an electronics unit 20.

The first housing part 31 and the second housing part 32 are configured and joined such that the electronics unit 20 is enclosed by the housing 30. Furthermore, the first housing part 31 and the second housing part 32 are configured as films. The housing parts 31, 32 can be produced, for example, by deep drawing of a film, in particular by thermoforming. Preferably, the film can be, for example, a plastic film, which particularly preferably has a thickness of between 0.1mm and 5 mm. The plastic film here particularly preferably comprises a biomaterial. Alternatively, however, it is also possible for only one of the housing parts 31, 32 to be formed as a film.

In this case, the second housing part 32 has, in particular, an adhesive material in the form of an adhesive coating. The second housing part 32 particularly preferably has a double-sided adhesive coating and is configured, for example, as a double-sided adhesive tape, whereby the second housing part 32 can be bonded to the first housing part 31, in particular.

The first housing part 31 is more elastically configured inside the first region 51 than outside the first region 51. This increased elasticity in the first region 51 is achieved by: the first region 51 has at least in part the recess 34 and/or the first housing part 31 within the first region 51 is at least partially thinner than the first housing part 31 outside the first region 51.

The first region 51 has, in particular, a recess 34, the wall thickness of which is reduced compared to the wall thickness of the first housing 31 outside the first region 51. The wall thickness of the bottom of the groove 34 is particularly preferably reduced here.

Furthermore, the film of the first housing part 31 and/or of the second housing part 32 can be at least partially optically transparent. This can be achieved by: the film is of such a thin design that the optical transparency of the film is achieved. Alternatively, the film may have, for example, the following material composition: the material component is transparent to optical radiation, in particular in a predefined wavelength range. Alternatively, the film can also be applied locally such that the housing parts 31, 32 have an optical transparency in the respective region only for optical radiation having a predefined wavelength.

The first housing part 31 also has a second region 52, the second region 52 being configured such that the stability of the first housing part 31 is greater within the second region 52 than outside the second region 52. Furthermore, the first housing part 31 has, in particular, a third region 53, which has protection against lifting of mechanical influences compared to the outside of the third region 53. The second region 52 and the third region 53 can be part of the upper side 35 of the first housing part 31, wherein the first housing part 31 is arranged in the third region 53 offset with respect to the second region 52 in such a way toward the interior of the housing 30 that the third region 53 is surrounded by the higher second region 52.

Additionally or alternatively, at least one of the second regions 52 of the first housing part 31 may have at least one edge 45, wherein this second region 52 comprises in particular the side wall 37 of the first housing part 31, wherein the edge 45 extends in particular parallel to the upper edge 38 of the side wall 37. In this exemplary embodiment, this second region 52 of the first housing part 31 also has a further edge 46, which likewise increases the stability of the housing 30 and is configured in such a way that it can be used, for example, additionally for positioning the electronics unit 20 relative to the first housing part 31 or also for positioning the second housing part 32 relative to the first housing part 31.

The electronics unit 20 has, for example, a circuit board 21 on which the corresponding electronic components are arranged. These electronic components may be, for example, the sensor unit 22 and/or the switching element 23 and/or the communication unit 24.

The sensor unit 22 may have, for example, an acceleration sensor and/or a temperature sensor and/or a magnetic field sensor and/or a humidity sensor and/or a light sensor in order to sense a corresponding environmental parameter, for example air humidity or vibrations.

The switching element 23 is, for example, in the form of a push button and is arranged in such a way that the switching element 23 can be actuated in an actuating direction 60 from outside the housing. For this purpose, the switching element 23 can be arranged in such a way that it is located in the actuating direction 60 below a third region 53, which is surrounded by a corresponding elastic first region 51. The upper side 61 of the switching element 23 extends in particular parallel to the upper side 35 of the first housing part 31 in the third region 53.

The communication unit 24 may be configured in particular as a wireless communication unit, for example as a WLAN unit and/or as a bluetooth unit and/or as an LoRa unit and/or as a mobile radio unit.

Fig. 3 shows a second cross section of the first embodiment of the device according to the invention according to fig. 1.

The cross-sectional plane includes the line of intersection B shown in fig. 1 and extends through the apparatus 10 perpendicular to the line of intersection B, which is represented by the double arrow B1.

The electronics unit 20 additionally has, for example, an energy supply element 25 and/or a further switching element 23.

The energy supply element 25 may have, for example, an energy store and/or an energy recovery unit. The energy store may have, for example, a battery and/or a capacitor.

In this case, the further switching element 23 is configured such that its actuating direction 60 extends perpendicularly to the actuating direction 60 of the switching element 23 disclosed in fig. 2. Accordingly, the side wall 37 of the first housing part 31 is configured in such a way that it has a further recess 34 which surrounds a surface which is parallel to the upper side 61 of the further switching element 23 in the actuating direction 61 of the further switching element 23. This enables a lateral actuation of the further switching element 23.

Furthermore, the electronics unit 20 may have, for example, a processing unit 26 and/or a memory element 27 and/or a display element 28.

The processing unit 26 can be configured, for example, as a microcontroller and can in particular also already have integrated a memory element 27.

The display element 28 may have, for example, a light emitter or a display.

By equipping the circuit board 21 with corresponding electronic components, the electronics unit 20 can be configured as a data logger, which can sense and store environmental parameters. In order to be able to use the electronics unit 20 as a data logger, at least the sensor unit 22 and the memory element 27 are required in particular. Thus, the device 10 may be used to monitor an object. The object may be a transport item, for example.

Fig. 4 shows a cross section of a second embodiment of the device according to the invention.

This section follows the section according to fig. 2, wherein the devices of both embodiments are configured almost identically.

The second exemplary embodiment differs from the first exemplary embodiment in that the second housing part 32 extends as far as into an edge region 38 of the housing 30, which also has the fastening element 40, and extends parallel to the first housing part 31 in this edge region 38. The first housing part 31 is welded, for example, to the second housing part 32 in an edge region 38 of the housing 30. However, it is also conceivable for the first housing part 31 and the second housing part 32 to be additionally or alternatively bonded to one another in the edge region 38.

The electronics unit 20 can also be glued to the second housing part 32, for example, via its printed circuit board 21. Additionally or alternatively, the electronics unit 20 can also be clamped between a first housing part 31 and a second housing part 32, which are correspondingly configured for this purpose, in order to fix the electronics unit 20 in the housing 30.
