Detailed Description
The following detailed description of specific embodiments of the present disclosure is provided in connection with the accompanying drawings. It should be understood that the detailed description and specific examples, while indicating the present disclosure, are given by way of illustration and explanation only, not limitation.
Fig. 1 is a schematic block diagram illustrating a system for supplying power in a vehicle according to an exemplary embodiment of the present disclosure, the system including a battery 200; a controller 300, the controller 300 being configured to control the battery 200 to power a vehicle; the charging interface 100 is used for providing a charging interface for equipment, and the controller 300 is connected with the charging interface 100 in parallel and then connected with the battery 200. For example, the controller 300 may determine whether the vehicle is in a power-on state according to whether a signal sent by an Electronic Control Unit (ECU) is received, and after receiving the signal sent by the ECU, determine that the vehicle is currently in the power-on state, so that the battery 200 can supply power to the vehicle. The controller 300 may also be, for example, a relay that conducts when the vehicle is powered on so that the battery 200 can power the vehicle. When the vehicle is not powered on, the controller 300 is in the off state, and at this time, the device can still be charged by using the battery 200 because the charging interface 100 is directly connected to the battery 200. In this way, no matter whether the vehicle is powered on or not, the charging interface 100 can charge the device through the battery 200, and the vehicle is not required to be powered on for charging the device, so that the device can be charged in the vehicle more conveniently and quickly, the extra electric energy consumed by the power-on of the vehicle is reduced, and the potential safety hazard caused by the in-situ parking after the power-on of the whole vehicle is reduced.
At present, a charging interface capable of charging devices such as a mobile phone or a tablet computer is usually arranged in a common vehicle, the charging interface can be a USB interface directly connected with a charging wire, or an interface after an inverter is inserted into a cigarette lighter, but whatever the charging interface is, the charging interface is required to charge the devices of a user when the vehicle is in a power-on state, and when the vehicle is not in the power-on state, no electricity is arranged on the charging interface. When the vehicle is in the power-on state, the whole vehicle circuit in the vehicle is in the conducting state, many relays in the circuit, for example, the controller 300, are also in the attracting state, and many parts unrelated to the charging interface are also in the working state, such as the instrument panel and the like. This results in excessive unnecessary power consumption during charging, and maintaining this state for a long time may result in a power shortage of the vehicle battery, etc. In addition, if the vehicle is powered on for charging the equipment and is parked in place after the vehicle is powered on, great potential safety hazards are brought, and the vehicle is in an unlocked state after the vehicle is powered on, so that certain safety threats are brought to people or articles in the vehicle. In the system for supplying power in a vehicle according to an exemplary embodiment of the present disclosure, the charging interface 100 and the battery 200 can be used to provide power for the device without powering the entire vehicle, so that the device can be charged more conveniently and quickly in the vehicle, and the potential safety hazard caused by in-situ parking after the entire vehicle is powered on is also reduced.
In a possible embodiment, as shown in fig. 2, the charging interface 100 includes a first pin 1 and a second pin 2, where the first pin 1 is used to connect to the positive pole of the battery 200, the second pin 2 is used to connect to the negative pole of the battery 200, and the first pin 1 and the second pin 2 are used as the positive pole and the negative pole of the power supply of the device, respectively.
In a possible embodiment, as shown in fig. 2, the charging interface 100 further includes a third pin 4 and a fourth pin 5 for providing a data transmission channel for the device. In this way, the device can be charged not only through the first pin 1 and the second pin 2 of the charging interface 100, but also can perform data transmission with the corresponding device through the third pin 4 and the fourth pin 5. For example, when the charging interface 100 is connected to the internal circuit of the vehicle, the device can be charged by the charging interface 100 using the power supply in the vehicle, such as the vehicle battery 200, and can also perform data transmission with the media device in the vehicle through the charging interface 100, so that the functions of the charging interface 100 are enriched, and the user experience is more complete.
In a possible implementation manner, the system further includes a control module (not shown) connected to the third pin 4 and the fourth pin 5, and configured to allow data to pass through on the third pin 4 and the fourth pin 5 when receiving a power-on signal sent by the controller 300. The control modules include a first control module 500 and a second control module 400.
Fig. 3 is a schematic block diagram of a system for supplying power in a vehicle according to yet another exemplary embodiment of the present disclosure, and as shown in fig. 3, the system further includes a first control module 500 and a second control module 400, wherein the controller 300 is connected to the first control module 500 after being connected in parallel with the charging interface 100, and then connected to the battery 200, and the controller 300 is configured to send a power-on signal to the first control module 500 when the battery 200 starts to supply power to the vehicle through the controller 300; the third pin 4 and the fourth pin 5 are both connected to the second control module 400, and the first control module 500 is configured to periodically send a control signal to the second control module 400 after receiving the power-on signal, so that the second control module 400 allows data on the third pin 4 and the fourth pin 5 to pass through.
The first control module 500 may be, for example, a Vehicle Control Unit (VCU), and the battery 200 is connected to the charging interface 100 and the controller 300 after the first control module 500 is connected.
When the vehicle is powered on, the controller 300 sends a power-on signal to the first control module 500 to inform the first control module 500 that the vehicle is powered on. After receiving the power-on signal, the first control module 500 sends a control signal to the second control module 400 connected to the charging interface 100, so that the second control module 400 allows data to pass through the third pin 4 and the fourth pin 5 in the charging interface 100, that is, allows the device to perform data transmission with the vehicle through the charging interface 100. The data transmission can be from the vehicle to the device, or from the device to the vehicle. The device may be, for example, a USB flash drive, in addition to a mobile phone, a tablet computer, an MP3, an MP4, and the like.
In a possible implementation, the second control module 400 is further configured to send a reply instruction to the first control module 500 after receiving the control signal; the first control module 500 is further configured to stop sending the control signal to the second control module 400 after receiving the reply signal sent by the second control module 400.
In a possible embodiment, the first pin 1 and the second pin 2 are both connected to the second control module 400, and the charging interface 100 further includes a protection device 3. As shown in fig. 4. Fig. 4 is a schematic structural diagram of charging interface 100 according to an exemplary embodiment of the present disclosure. The protection device 3 is disconnectably connected between the first pin 1 and the second pin 2, when a device is inserted into the charging interface 100, the protection device 3 is disconnected from the first pin 1 and the second pin 2, and when no device is inserted into the charging interface 100, the protection device 3 is connected between the first pin 1 and the second pin 2, so as to form a short circuit between the first pin 1 and the second pin 2.
Since the second control module 400 is connected to the first pin 1 and the second pin 2 in the charging interface 100, and the protection device 3 is arranged between the first pin 1 and the second pin 2 to connect the first pin 1 and the second pin 2, when no device is inserted into the charging interface 100, the first pin 1 and the second pin 2 are in a short-circuit state, so that when no device is inserted into the charging interface 100, the second control module 400 is also in a short-circuit state, and no current passes through the second control module 400, at this time, even if the first control module 500 receives the power-on signal sent by the controller 300, the control signal is sent, and the second control module 400 cannot receive the power-on signal. Therefore, when receiving a power-on signal sent by the controller 300 and representing that the entire vehicle is powered on, the first control module 500 needs to periodically send a control signal to the second control module 400, which can ensure that after the device is inserted into the charging interface 100 at any time and the second control module 400 is connected to the circuit, the second control module 400 can receive the control signal.
After the second control module 400 confirms that the control signal sent by the first control module 500 is received, a reply signal is sent to the first control module 500, so that the first control module 500 stops sending the control signal continuously, and the work of the first control module 500 can be more reasonable and scientific.
In the charging interface 100 shown in fig. 4 according to an exemplary embodiment of the present disclosure, when no device is inserted into the charging interface 100, since the first pin 1 and the second pin 2 are both connected to the protection device 3, and the protection device 3 can form a short circuit between the first pin 1 and the second pin 2, even if the charging interface 100 is always kept in a charged state, as long as no device is inserted into the charging interface 100, no current flows through the second control module 400 connected to the charging interface 100, so that the charging interface 100 can be equivalent to one wire and has almost no power consumption when no device is inserted. When a device is inserted into the charging interface 100, since the protection device 3 is disconnected from both the first pin 1 and the second pin 2, the first pin 1 is connected to the positive electrode of the power supply for supplying power to the charging interface 100, the second pin 2 is connected to the negative electrode of the power supply for supplying power to the charging interface 100, the first pin 1 is used as the positive electrode of the power supply for the device, and the second pin 2 is used as the negative electrode of the power supply for the device, after the device is inserted into the charging interface 100, the device can be connected to the circuit for supplying power to the charging interface 100 through the first pin 1 and the second pin 2, so as to perform charging operation.
Through the technical scheme, when the charging interface 100 is connected in the circuit, the protection device 3 in the charging interface 100 can enable the charging interface 100 to be equivalent to a wire before the device is inserted, almost no power consumption exists, but the power supply in the circuit is timely enabled to supply power through the charging interface 100 after the device is inserted, so that the charging interface 100 does not consume extra electric quantity when no device is inserted, and the power consumption safety degree of the charging interface 100 is improved.
Since the protection device 3 needs to form a short circuit between the first pin 1 and the second pin 2 when the device is not inserted into the charging interface 100, the protection device 3 should be a material that is easily conductive. In one possible embodiment, the protective device 3 is made of a metallic material. The metal material can be a pure metal material or an alloy material. The most suitable metal material may be selected according to the actual situation, as long as it can form a short circuit between the first pin 1 and the second pin 2 when the protection device 3 is connected between the first pin 1 and the second pin 2.
In a possible embodiment, as shown in fig. 5, the protection device 3 includes a metal sheet 31 and a metal pin 32, wherein when no device is inserted into the charging interface 100, the metal sheet 31 is connected to the first pin 1 and the second pin 2 through the metal pin 32, and when the device is inserted into the charging interface 100, the metal pin 32 is separated from the first pin 1 and the second pin 2, so that the connection between the metal sheet 31 and the first pin 1 and the second pin 2 is disconnected. The metal pins 32 are integrated with the metal sheet 31 to form the protection device 3. The metal material constituting the metal sheet 31 and the metal pins 32 may be any metal material, such as a pure metal material or an alloy material. The corresponding relationship between the metal sheet 31 and the metal pins 32 can be one-to-many, that is, a plurality of metal pins 32 can be integrated on the same metal sheet 31.
In a possible embodiment, the metal pins 32 are arc-shaped metal elastic pieces, and a schematic diagram of the arc-shaped metal elastic pieces is given in fig. 5. Two arc-shaped metal elastic pieces can be integrated on the metal sheet 31, and are respectively connected with the first pin 1 and the second pin 2 when no device is inserted into the charging interface 100. When a device is inserted into the charging interface 100, the device will separate the arc-shaped metal elastic sheet from the first pin 1 and the second pin 2, that is, disconnect the protection device 3 from the first pin 1 and the second pin 2. And because the arc-shaped metal elastic sheet is elastic, when the device is pulled out from the charging interface 100, the arc-shaped metal elastic sheet can automatically recover to the state of being connected with the first pin 1 and the second pin 2, so that the charging interface 100 can almost have zero power consumption under the condition that the device is not inserted, and after the device is inserted, the charging interface 100 can timely connect the device into a power supply circuit for charging.
In a possible embodiment, the second control module 400 is further configured to perform at least one of overcurrent protection, overvoltage protection, and overheat protection on the charging interface 100.
In a possible embodiment, the second control module 400 may also be integrated into the charging interface 100.
The present disclosure also provides a vehicle comprising a system for supplying power in a vehicle as described above.
The preferred embodiments of the present disclosure are described in detail with reference to the accompanying drawings, however, the present disclosure is not limited to the specific details of the above embodiments, and various simple modifications may be made to the technical solution of the present disclosure within the technical idea of the present disclosure, and these simple modifications all belong to the protection scope of the present disclosure.
