The power module 30 can disconnect the power supply loop of the low-voltage apparatus when the control signal is an abnormal signal. The main controller 10 receives the state parameters, which are corresponding parameters of each component in the vehicle in different operating states, and generates the control signals according to the state parameters.
To further intuitively illustrate the distribution box of the present invention, fig. 2 is a diagram showing a possible three-dimensional modeling structure of the distribution box in the embodiment of the present invention, where fig. 2 includes: the main controller 10, the fets 301, the FPC40, the sheath 50, the connector 60, and the fixing holes 70, 71, wherein, for simplicity of illustration, only a few fets 301 are shown in fig. 2, which does not represent that only these fets can be found in the distribution box of the present invention.

Because the distribution box is manufactured based on the FPC, as can be known from figure 2, the distribution box can be bent and folded, the distribution box of the invention does not have the problems that the conventional hard distribution box is large in size, high in weight and not suitable for complex assembly positions, and the requirement on assembly space is lower.
In an embodiment of the present invention, a modular schematic diagram of a preferred distribution box is shown in fig. 3, where a main controller 10 includes: a communication controller 101; the power module 30 further includes: a drive circuit 302 and a feedback circuit 303. The power management module 20 is connected to the battery BAT and the power module 30 of the vehicle, and the fet 301 is connected to the low-voltage devices, it should be noted that in practical applications, there are a plurality of low-voltage devices, and therefore there are also a plurality of fets. The communication controller 101 is connected to CAN buses (CAN H and CAN L in fig. 2) of the vehicle, performs data interaction, and the communication controller 101 receives the status parameters through the CAN buses and forwards the status parameters to the main controller 10.

Thereby achieving the goal of controlling the power module 30.
In the following, the functions of the distribution box of the present invention are described in a specific example, and the functions described in the specific example are exemplary of the functions that the distribution box can implement, and do not mean that the distribution box of the present invention can implement only these functions. Referring to fig. 4, the power management module is connected to the battery BAT and is also connected to other components of the distribution box that need to be powered, so as to provide working power for all the components of the distribution box. The MCU is a main controller, the MCU can normally work only by a crystal oscillator circuit, and the downloading and debugging interface is used for connecting external equipment so as to download and debug the control program in the MCU. A CAN transceiver for communicating with a CAN bus: the CAN H and the CAN L carry out data interaction; and the Mirror Link transceiver is used for carrying out data interaction with the cloud platform through the LIN line. The switching value detection circuit is used for receiving: the control system comprises an ACC signal, an IG signal, a rear defrosting feedback signal, an engine room cover switch signal, a child lock state signal, a back door micro switch signal, a position lamp fault signal, a steering lamp fault signal and a brake lamp fault signal, and the signals are fed back to the MCU, and the MCU can generate corresponding control signals according to the signals.
The MOS tube 1 controls the high beam and the low beam according to the control signal of the MCU, when the power is turned on, the power provided by the power management module is transmitted to the high beam or the low beam, so that the high beam or the low beam is turned on, and when the power is turned off, the power provided by the power management module cannot be transmitted to the high beam or the low beam, so that the high beam or the low beam is turned off, and in general, the high beam and the low beam have 2 sets, respectively, so that fig. 4 shows a high beam 2 and a low beam 2, which can be distributed to the MOS tube and the control method according to the actual situation; the MOS tube 2 controls the left steering lamp and the right steering lamp according to the control signal of the MCU, and the control mode is the same as that of the far and near turning-off lamps, so that the detailed description is omitted. Similarly, the left and right turn signal lamps also have 2 groups, and therefore, the left turn signal lamp x 2 and the right turn signal lamp x 2 are shown in fig. 4, and the MOS transistors and the control method can be distributed according to actual conditions.
The MOS tube 3 controls the child lock relay according to the control signal of the MCU, when the child lock relay is closed, the power supply provided by the power supply management module is transmitted to the child lock relay, so that the child lock relay is electrified and starts to work, and when the child lock relay is disconnected, the power supply provided by the power supply management module cannot be transmitted to the child lock relay, so that the child lock relay cannot work after being electrified; MOS pipe 4 is according to MCU's control signal control electric horn, and when it was closed, the power transmission that power management module provided was to electric horn for electric horn gets electric and sends the loudspeaker sound, and when its disconnection, the power that power management module provided can't transmit to electric horn, makes electric horn lose electric and can't send the loudspeaker sound. If the electric horn is provided with the temperature sensor, the working temperature detected by the temperature sensor CAN be transmitted to the MCU through the CAN bus and the CAN bus transceiver, the MCU receives the working temperature, the working temperature is compared with the preset temperature threshold value of the electric horn, if the received working temperature does not exceed the temperature threshold value, a control signal is generated, the control signal is a normal signal, the MOS tube 4 is continuously controlled to be closed, and the electric horn CAN continuously emit horn sound; if the received working temperature exceeds the temperature threshold, a control signal is generated, the control signal is an abnormal signal and controls the MOS tube 4 to be disconnected, and the electric horn cannot make a horn sound. Through the method, the over-temperature protection of the element is realized, and the method for generating the control signal by the MCU according to the working current, the working voltage and the like is similar to the method for generating the working temperature, and is not repeated. Overcurrent and overvoltage protection can be realized in a similar way. Therefore, the distribution box disclosed by the invention has the advantages that the MOS tube is utilized to realize the control of the low-voltage apparatus, and meanwhile, the safety protection effect on the low-voltage apparatus is also realized, so that the MOS tube is equivalent to replace the conventional relay and fuse, the number of elements in the distribution box is further reduced, and the volume of the distribution box is indirectly reduced. In addition, for the same element, if the element is repeatedly started for a plurality of times within preset time, a short-circuit protection mechanism is triggered, the open state of the field effect transistor is kept, and the field effect transistor is not controlled to be closed any more. Compared with the conventional distribution box which only uses a fuse to perform overcurrent protection on elements, the distribution box has the advantages of wider protection range, more functions and higher protection speed, and the reaction time of the field effect transistor reaches microsecond level.
The control of the front windscreen wiper at high and low speeds, the control of the front windscreen wiper and the control of the rear windscreen wiper for washing and the like can use fuses as safety protection, each fuse is independently configured, when working current overflows, the fuses can be automatically fused, and the specific connection relation can be seen in fig. 4 and is not described any more. Of course, MOS transistors may be used to control these devices, and the occupied space of the distribution box may be large, and may be selected according to actual requirements.
In addition, in the embodiment of the invention, the power management module can also realize intelligent and graded management of static power consumption. For example: when the electric quantity of a storage battery of the vehicle is higher, more elements can be in a normal electric state; with the gradual reduction of the electric quantity of the storage battery, part of the components can be turned off to be in a dormant state or be directly powered off.
In an embodiment of the present invention, based on the above power distribution box, an embodiment of the present invention further provides an automobile, where the automobile includes: a distribution box as hereinbefore described.
The power distribution box uses the field effect tube to replace the current relay and fuse, and because the time required by the field effect tube for switching off is extremely short and reaches microsecond level, the safety protection requirement of extremely low fusing time (microsecond to several milliseconds) of a low-voltage apparatus can be met. And because the existence of master controller, can control field effect transistor's closure, turn-off, so field effect transistor can realize the function of relay to make field effect transistor replace fuse and relay. In addition, because the flexible printed circuit board is manufactured based on the FPC, the flexible bending wiring design performance is achieved, the occupied space of the distribution box is extremely small, and the flexible bending wiring design is suitable for assembly and application of complex positions with narrow structures. The FPC conformal structure can well meet the size requirement of the installation environment, has flexible assembly performance, and solves the installation difficulty in narrow space. Meanwhile, real-time monitoring and early warning prompting of working temperature, current, voltage and the like are achieved, vehicle driving safety is guaranteed, the system has the function of vehicle networking, can be in real-time communication with the cloud platform, and achieves big data interaction with the cloud platform. The distribution box has extremely high practicability.
