Abstract
Description
Technical Field
[0001] The utility model relates to a vehicle component, a vehicle component control device and a vehicle component with the vehicle component control device. Background Art
[0002] Similar vehicle components, such as those known from DE 10 2016 217 252 A1 or DE 10 2016 219 658 B3, can be adjusted manually, electrically or pneumatically. Pneumatic systems are preferably used in motor vehicle seats, for example to fill or empty a bladder that can be filled with a fluid. Such bladders are often used, for example, to assume massage functions or seat adjustment functions in motor vehicle seats.
[0003] For this purpose, the system is usually pressurized and a plurality of such bladders are filled or emptied via a fluid-carrying section, such as a common rail system. The pressure in the fluid-carrying section is generated by means of a pump or a plurality of pumps. Such pumps have a certain size due to the requirements of operational safety and durability and often generate disturbing operating noise. For this reason, the pumps must be packaged in a complex manner in order to avoid disturbing noise. Utility Model Content
[0004] The object of the invention is to create a vehicle component control device which does not have the above-mentioned disadvantages and is therefore of compact and low-noise construction.
[0005] The object is achieved by a vehicle component control device, a vehicle component and a vehicle comfort system.
[0006] According to the utility model, the vehicle component control device has a circuit board, which has an electrical or electronic control device arranged thereon and a plurality of components for guiding fluids arranged on the circuit board. The components are, for example, pipelines and / or valves. The arrangement structure of the pneumatic components and the electrical and / or electronic control devices can realize a compact structural type, so that the vehicle component control device can be used in many aspects. In addition, according to the utility model, the vehicle component control device has at least one piezoelectric pump or dielectric pump for supplying fluid to the components, which is arranged on the circuit board and electrically connected to the circuit board. The piezoelectric pump or dielectric pump has a small amount of moving parts and can be constructed very compactly. By having less friction during operation, the noise generation is low, so that this pump can run very quietly. Therefore, the entire vehicle component control device can be arranged on the circuit board and used in the immediate vicinity of the application. Due to the low noise of the piezoelectric pump or dielectric pump, even if the control device is arranged in the passenger compartment, the vehicle occupants are not disturbed by the operation of the device.
[0007] In a preferred embodiment, the piezoelectric pump or dielectric pump is a disk pump, a diaphragm pump or an ultrasonic pump. These are the most common embodiments of piezoelectric pumps or dielectric pumps.
[0008] In a particularly preferred embodiment, the control device is configured to operate one or more of the piezoelectric or dielectric pumps unidirectionally or bidirectionally. The simplest embodiment is to operate the piezoelectric or dielectric pump unidirectionally, ie to pump fluid into the system using the pump.
[0009] In an extended embodiment, the pump can be used to pump fluid both into the system and out of the system, i.e. to use the pump bidirectionally. Limiting factors of the piezoelectric or dielectric pumps are, on the one hand, the relatively low pumping volume, which limits the capacity of the individual pumps, and, on the other hand, the compression factor of the pump, which limits the output pressure. These limiting factors can be addressed by a plurality of pumps. The pumping volume can be increased by using pumps connected in parallel. Connection in series can generate higher output pressures in a stepped manner.
[0010] The object according to the invention is also achieved by a vehicle component having at least one fluid actuator and a vehicle component control device according to the invention as described above, which is fluidically connected to the at least one fluid actuator and controls the at least one fluid actuator. Such a vehicle component can also be operated using a pneumatic control device without disturbing the vehicle occupants.
[0011] In a preferred embodiment, the fluid actuator is a fluid-fillable bladder. A bladder is the simplest form of a fluid actuator and can be used in motor vehicles in a wide variety of applications.
[0012] In another preferred embodiment, the or each piezoelectric or dielectric pump is directly or indirectly connected to one or more fluid actuators. Depending on the size and complexity of the vehicle components to be controlled, the piezoelectric or dielectric pump can be connected directly to the fluid actuator, wherein a system comprising a plurality of such arrangements can certainly be present. On the other hand, it is also possible to operate a pressure system, such as a common rail, with one or more pumps, from which a plurality of fluid actuators can be operated.
[0013] Furthermore, the object according to the invention is achieved by a vehicle comfort system having one of the above-described vehicle components according to the invention. The system can be produced compactly and cost-effectively, since cost-effective vehicle components can be used, in which disturbing noises are avoided by using a piezoelectric or dielectric pump. Due to the low noise, the passengers themselves are not disturbed by the operation of the vehicle component control device.
[0014] Whenever a dielectric pump is mentioned in this application, this always refers to an electrically operated pump, which has a dielectric elastomer as a component. Therefore, the dielectric pump can also be called a dielectric elastomer pump. Compared with a piezoelectric pump, such a dielectric pump additionally has the advantage that the dielectric pump requires a lower voltage to operate. Accordingly, cheaper or fewer electrical components are required when installing the dielectric pump. Therefore, the size of the circuit board used can also be reduced again. The dielectric elastomer is used as an actuator in that the dielectric elastomer is mechanically deformed when an electric field is applied. This mechanical deformation is used to perform a pumping motion, for example, to perform the motion of a diaphragm in a diaphragm pump. BRIEF DESCRIPTION OF THE DRAWINGS
[0015] The present invention will be described in more detail below with reference to embodiments.
[0016] Here, Figure 1 An oblique view of a vehicle component control device according to an embodiment of the invention is shown. DETAILED DESCRIPTION
[0017] Figure 1 A compact vehicle component control device 1 is shown, in which all components are arranged on a circuit board 7. Here, not only the electrical control device 4 and the electronic control device 5 but also the components 2, 3, 6, 8 that conduct the fluid are arranged on a circuit board 7. In this embodiment, the line 6 to the valve 2 is guided in a U-shaped manner, and the valve controls the outlet 8 of the fluid to the fluid actuator (not shown). In addition, a piezoelectric pump or dielectric pump 3 is arranged on the circuit board 7, so that the pneumatic system does not require a fluid supply line from the outside, but can, for example, suck air from the environment as fluid. Not only the valve 2 but also the piezoelectric pump or dielectric pump 3 are electrically connected to the circuit board 7 and can thus be influenced (ansprechen) by the electrical control device 4 and the electronic control device 5 as required. Such a vehicle component control device 1 can be compact and space-saving due to the arrangement of the components on a circuit board 7. Here, the control devices 4, 5 only need electrical connections, which are almost everywhere in the vehicle. Due to the piezoelectric or dielectric pump, the vehicle component control device is also low-noise and does not require additional sound insulation, as is the case with known pneumatic vehicle component control devices.
