The advantage of the invention block security management for car, respectively proposed in the invention of the method of assembling such a control unit with the distinctive signs in the relevant independent claims, before known from the prior art solution is pre-fixing of the PCB on the plastic bottom and a plastic lid without using special tools. Thus PCB not need to attach the screws to the bottom of the chassis, respectively, in combination with a plastic cover. This significantly easier to assemble a control block. This provides a preliminary fixing implemented, for example, by simply pressing the friend to the friend bottom of the casing, cover, and printed circuit boards. The connection that binds between these parts, can be a connection with geometric and/or pressure. Decisive same importance is no need to use any tool for this connection. Other benefits consist of implementing lid and bottom, which together form the control unit casing is plastic.
When the Assembly proposed in the invention of the control unit is first on the printed circuit Board set mounted components, such as components for surface mounting, which are then fixed to a printed circuit Board soldering reflow solder (meltdown tinned coatingand). After that, through the articulation between a circuit boards, plastic bottom and plastic covers provide a pre-commit to each other for what, for example, use the locking tabs holding the case of the control unit in the assembled state. The case of the control unit together in a plastic cover and plastic bottom. In the future when mounting on the vehicle for such installation is used, for example, screws, passed through the plastic cover, printed circuit Board and plastic bottom.
According to the present invention, the controller unit is a device that processes signals of sensors and depending on the results of processing of such signals if necessary generates control signals to operate or intensification of security tools. Under security means the airbag, seatbelt tensioner safety or active headrest. Under security includes other security features, such as the protection of pedestrians, other airbags and other safety devices, ensuring the protection of occupants of people, pedestrians from hurting.
Under the arrangement of electric components on the Board means installation or Assembly of the variety of electrical, and electronic components and their subsequent fixation on her surface mount technology. You can also use more than one of the PCB. PCB is the basis on which the electrical components are located and which provides the electrical connection between them. The PCB also has performance characteristic of conventional electronic circuits.
Plastic cover and plastic bottom is made of plastic, which primarily ensures the electromagnetic compatibility of the control unit. The lid and the bottom can thus manufacture from materials such as PBT-GF30 and RE GF30. If necessary, the composition of such materials to improve their electrocranial properties, i.e. to improve electromagnetic compatibility, you can enter appropriate additions.
Plastic cover and plastic bottom mutually agreed upon so that when assembled with each other they form the case of the control unit.
