The invention further relates to a motor vehicle having a measuring device according to the invention.
Description
Technical Field
The invention relates to a measuring device for measuring fine dust for a motor vehicle, comprising at least one laser light source, at least one optical receiver, at least one control device, at least one measuring chamber, and at least one housing, which at least partially encloses at least one component of the measuring device.
Background
Measuring devices of the type mentioned at the outset are frequently used in motor vehicles to check the particle content of the air in the vehicle interior. For this purpose, the measuring devices usually have a laser light source, from which the air volume to be examined is irradiated with laser light. The volume of air to be examined is accommodated for this purpose in a measuring chamber. The laser light is detected by an optical receiving device after passing through the air volume. By means of the evaluation device, the signal detected by the receiving device can be evaluated and, for example, the dust particle concentration can be deduced. Due to the large number of components to be installed, the integration and assembly of corresponding measuring devices into a motor vehicle is time-consuming and therefore costly.
Disclosure of Invention
The object on which the invention is based is to propose a measuring device of the type mentioned at the outset, with which a simple and time-saving assembly of the measuring device can be achieved.
This object is achieved with a device having the features of claim 1. Advantageous embodiments and developments are specified in the dependent claims.
In a measuring device for measuring fine dust for a motor vehicle, having at least one laser light source, at least one optical receiver, at least one measuring chamber and at least one housing, which at least partially encloses at least one component of the measuring device, the invention provides for the essential features of: at least one housing is formed from at least two housing parts, which are designed as housing flaps assigned to one another, the at least two housing flaps assigned to one another forming a basic housing in a mutually abutting manner, and the at least two housing flaps assigned to one another forming an outer housing in a mutually abutting manner, which surrounds the basic housing. The measuring device, for example a particle sensor arrangement, which can be composed, for example, of a laser light source, a measuring chamber and an optical receiver, is mounted in the housing. The housing parts can be designed as housing flaps which correspond to one another, in particular as housing flaps which correspond to one another in pairs. The housing has, for example, two housing flaps which are designed in such a way that they form a housing which surrounds the component in a mutually abutting manner. For this purpose, the housing flaps can have, for example, mutually corresponding projections and recesses which enable a reliable connection of the housing flaps. For example, the housing flaps can also be connected to one another by means of clip connections, snap connections or similar connecting means. By placing the basic components of the measuring device (e.g. laser light source, measuring chamber and receiving device) in the housing, a simple and time-efficient assembly possibility of the measuring device is provided. In particular, in this case, the measuring device is enclosed by a basic housing and an outer housing which encloses the basic housing. Different components can be arranged in the basic housing and in the outer housing. Thus, a modular construction of the measuring device is achieved. For example, components of the dust sensor arrangement (e.g. a laser light source, an optical receiver, a control device and a measuring chamber) can be arranged in the base housing. This basic housing is therefore designed independently as a complete measuring device for measuring fine dust. Other optional components (such as ventilators or the like) that can be required according to given requirements can be placed in the outer housing.
In one embodiment of the invention, the at least one separating surface of the basic housing and the at least one separating surface of the outer housing are perpendicular to one another. The basic housing and the outer housing can be composed of mutually corresponding housing flaps. For example, the housing petals can be configured as housing half petals and the basic housing can be formed by two housing half petals. The housing halves can be connected to one another along the separating plane of the basic housing. The basic housing can be surrounded by an outer housing, which is formed from two further housing halves, which are likewise connected to one another at a separating plane. The separating surfaces of the basic housing and the outer housing are perpendicular to each other. For example, the basic housing can have a horizontal partition, while the outer housing has a vertical partition. By orienting the separating surfaces vertically, a particularly stable and simple type of modular construction of the housing is provided.
In one embodiment of the invention, the basic housing encloses at least one laser light source and at least one measuring chamber. In the basic housing, the main components of the particle sensor system, such as the laser light source, the measuring chamber and the receiving device, can be arranged. Thus, a base module for a particle dust measuring device is formed by the base housing, which can be used independently and independently of the outer housing. For the evaluation, a signal-conducting connection to an external evaluation device can be established.
In one embodiment of the invention, the basic housing encloses at least one evaluation device and at least one control device. The evaluation device and the control device can be used for evaluating the laser radiation detected by the optical receiving device or for controlling the measurement. The combination of the laser light source, the measuring chamber and the optical receiving device provides a complete measuring device for detecting the dust particles. The evaluation device and the control device can also be used in a vehicle for controlling other methods or processes.
In one embodiment of the invention, at least one shell flap forming the basic shell has at least one receiving structure for receiving at least one component to be enclosed. The housing lobe can have a receiving structure for receiving a component, in particular for receiving an electronic component (for example the laser light source, an evaluation device or an optical receiving device). Simple mounting of the components required for the dust sensor arrangement is achieved by these receiving structures. The different components can be mechanically fixed by the receiving structure. In this case, for example, snap connections, clip connections or the like can be used. In this case, the receiving structure can be configured as a recess, receiving groove or the like and is adapted to the component to be received. In addition, the housing flap can have an air guide (for example one or more air guide channels) or this air guide can be formed by a structure, in particular by a structure of the joining of two housing flaps. The air guide channel can be used to introduce an air volume to be examined into the measuring chamber.
In one embodiment of the invention, at least one housing lobe forming the basic housing has at least one contact structure for electrical contacting of the component to be enclosed. The housing lobe can have a contact structure for electrically contacting a component to be received (for example the laser light source, the evaluation device or the optical receiving device). For example, the contact structure can be formed on the housing lobe by a conductor track or the like. In addition, the housing flap can have an electrically conductive plug connection for receiving the component. The housing flap can therefore be provided with the required electronic components simply by means of the prepared housing flap, without additional electrical contacts having to be made.
In one embodiment of the invention, the casing flaps forming the outer casing enclose at least one ventilation device in the joined state, and the casing flaps forming the outer casing have an air guide structure for forming an air guide channel in the joined state. The measuring device has at least one ventilation device, and a housing flap which forms the outer housing encloses the at least one ventilation device. The ventilation device is arranged in particular between the shell flaps of the outer shell and the shell flaps of the basic shell. Thus, the ventilation device can optionally be mounted by receiving the base housing into the outer housing. The outer housing, in particular the housing flaps of the outer housing, can have air guide structures which, in the engaged state of the housing flaps, form air guide channels. By means of the ventilation device, for example, an air volume to be examined can be introduced into the measuring chamber. For this purpose, the air guide channel can be connected to the measuring chamber in an air-guiding manner. The air guide can, for example, have a ventilation device for introducing the air to be examined. By adding the outer housing, the dust sensor system arranged in the base housing can be used independently of the ventilation device provided on the vehicle side, which can be required for operating the dust sensor system.
In one embodiment of the invention, at least one of the housing flaps forming the outer housing has at least one electrical contact for producing an electrically conductive connection between the component enclosed by the outer housing and the at least one component enclosed by the basic housing. By means of the mutual arrangement of the basic housing and the outer housing, an electrically conductive connection can be established between the component received in the outer housing and the component received in the basic housing. For example, a fan motor received in the outer housing can be attached to the base housing at an energy supply by an electrically conductive connection. Thus, the power supply itself is ensured by using the outer case without adding other components. In addition, the electrical contact ensures signal-conducting connection of the electronic components in the outer housing to the control device of the base housing. Thus, additional electronic components (e.g. ventilation devices) in the outer housing can be controlled by the control device in the basic housing.
In one embodiment of the invention, the outer housing has at least one air preparation device. The temperature or the air humidity of the air volume to be examined can be controlled, for example, by an air preparation device in the outer housing.
In one embodiment of the invention, the basic housing and the components enclosed by the basic housing can be used independently of the outer housing. A base member of the fine dust sensing mechanism is disposed in the base housing. In order to supply the particle sensor arrangement with the air volume to be examined, it is additionally necessary to have a ventilation device, for example an air guidance system. An air guide system with a ventilation device can be already present in a motor vehicle, for example, in an air conditioning system or in a ventilation device. The basic housing can be integrated in an already existing air guide system, so that the outer housing is only required if no ventilation device is present.
The invention further relates to a motor vehicle having a measuring device according to the invention. The modular construction of the measuring device with a base housing containing the basic components of the dust sensor arrangement and an outer housing containing optional components (e.g. ventilation) enables a good adaptation of the measuring device to the given conditions in the motor vehicle. For example, if a ventilation device into which the base housing can be integrated is already provided in the motor vehicle, a base housing without an outer housing can be used. If no ventilation device is present in the motor vehicle, an outer housing with a corresponding ventilation device can be arranged around the basic housing.
Drawings
In the following, the invention is further elucidated on the basis of an embodiment shown in the drawing. Showing in detail:
FIG. 1: a measuring device having a base housing and an outer housing.
Detailed Description
Fig. 1 shows a measuring device 1 with a basic housing 2 and an outer housing 3. The basic housing 2 is formed by two housing halves 4, 5. The housing halves 4, 5 are connected to each other at a separating surface 6. In the basic housing 2, a particle sensor system 7 is accommodated, which can be composed of a laser light source, a measuring chamber and a receiver. In addition, an evaluation device 8 for evaluating the dust particle measurement and a control device for controlling the measurement are arranged in the base housing 2. The base housing 2 has an air guide channel 9, through which an air volume to be examined can be introduced into the measuring chamber. The outer housing 3 has two housing flaps 10, 11 which are connected to one another at a separating plane 13. The separating plane 6 of the basic housing 2 and the separating plane 13 of the outer housing 3 are perpendicular to each other. A ventilation device 14 is arranged in the outer housing 3. The ventilation device 14 can be designed, for example, by a ventilation device (for example, a fan with an associated fan motor). In addition, the outer housing 3 can have an air preparation device 15, which is designed to regulate the air humidity and the air temperature. In order to monitor a parameter which is indicative of the air quality, the air preparation device 15 can have an air quality sensor. The ventilation device 14 and the air preparation device 15 can be connected to the evaluation device 8 in a signal-conducting manner. In order to introduce the air volume to be examined into the measuring chamber, the outer housing 3 has an air guide channel 16 which is connected in an air-guiding manner to the air guide channel 9 of the base housing 2. The base housing 2 with the control electronics, the evaluation device 8 and the fine-dust sensor system 7 arranged therein can be integrated into a ventilation device of a vehicle, for example, independently of the outer housing 3. If ventilation is not available, the outer housing 3 can be arranged around the basic housing 2, so that the measuring device 1 adds ventilation 14. Thus, ventilation means 14 and/or air preparation means 15 are optionally added to the components arranged in the basic housing 2 by means of the outer housing 3.
All features mentioned in the foregoing description and in the claims can be combined with the features of the independent claims by any choice. The disclosure of the present invention is therefore not limited to the described or claimed combinations of features, but rather all combinations of features that are significant in the framework of the invention can be regarded as being disclosed.
