Description
Technical Field

Background
The vehicle may need to be in standby for a long time during use, for example, a customer does not need to use the vehicle for a long time, or a spare vehicle without a vehicle is used when needed.
When the vehicle is not started, all electric devices are not powered off, in order to store vehicle operation data, have an alarm function after the vehicle is stopped and remotely wake up the vehicle, related electric devices (such as a whole vehicle controller and the like) of the vehicle are required to be in a normal power state, and the storage battery supplies power to the related electric devices.
When the vehicle is started and has high pressure, the power supply system of the vehicle is switched to be supplied with power by the charging device and charges the storage battery, wherein the charging device of the electric vehicle is a power battery, and correspondingly, the charging device of the fuel vehicle is a fuel engine and a generator which are connected with each other.
In order to ensure that the function of the vehicle is normal, the vehicle cannot be started for a long time, otherwise, the storage battery can be over-discharged, so that the whole vehicle controller has no current supply, the vehicle cannot be started finally, and data can be lost. Therefore, if the battery is determined not to be started for a long time, the negative wire of the battery needs to be pulled out, and the battery is reinstalled when the battery is started again. However, since the raw materials for manufacturing the secondary battery cannot achieve a purity of 100%, and impurities are always mixed in the middle, the secondary battery inevitably has an auto-discharge phenomenon even without a power consumption device, and therefore, the secondary battery is required to be periodically charged in any case. Even in the standby state, parts such as a vehicle controller of the vehicle are consumed, and the vehicle is waited for the next direct start, so that the standby time is short, and once the storage battery of the electric vehicle is in a power-shortage state for a long time, the battery is extremely unfavorable for later reuse, and the vehicle can not be started frequently because the standby time is too long. Moreover, pulling out the negative line of the battery also requires the user to have a certain electric theory basis and vehicle basic knowledge, which is too high for the user and is not safe.
In order to solve the above problem, CN210116466U in the prior art proposes to add an auxiliary energy storage component for dedicated starting, but it only solves the problem by increasing the number of batteries, and the increase of the number of batteries cannot reduce the standby power consumption of the vehicle per unit time.

Detailed Description
Preferred embodiments of the present invention are described below with reference to the accompanying drawings. It should be understood by those skilled in the art that these embodiments are only for explaining the technical principle of the present invention, and are not intended to limit the scope of the present invention. And can be adjusted as needed by those skilled in the art to suit particular applications. For example, although the whole vehicle controller 3 is described as an example of controlling the double-throw switch 5 through communication, the present invention may obviously adopt other schemes for control, and since the double-throw controller is a selection of the standby mode, it is obvious that the double-throw controller can directly select the normal continuous standby mode or the intermittent ultra-long standby mode using the energy storage timing switch 4 through manual control.
It should be noted that the ordinal numbers "first", "second", "third" in the description of the invention are used for descriptive purposes only and are not to be construed as indicating or implying relative importance.
Firstly, a power system for a vehicle in the prior art is explained, when the vehicle in the prior art is in a non-starting state, a vehicle control unit and some necessary electric devices are directly powered by a storage battery, in order to ensure that the storage battery is not in a power shortage state, the voltage of the storage battery can be detected by the vehicle control unit, when the voltage is too low, a power battery is started to charge the storage battery, or the vehicle control unit can start the power battery at regular time to supply power to the storage battery, however, the arrangement needs the vehicle control unit to continuously supply power, and the power in the power battery and the storage battery is continuously consumed until the power in the power battery and the storage battery are both exhausted, and the vehicle is in a power shortage state, so that the vehicle cannot be started at all.
In order to solve the above problems, the present invention provides several different embodiments, and a specific embodiment of an electric power system for a vehicle of the present invention is described below with reference to fig. 1.
As shown in fig. 1, in order to solve the problem of insufficient standby time of the conventional electric vehicle, the power system for a vehicle of the present invention includes:
the vehicle charging system comprises a charging device 1, a storage battery 2 used for standby and starting of a vehicle, a vehicle control unit 3 used for controlling the vehicle, and an energy storage timing switch 4, wherein the charging device 1 is electrically connected with the storage battery 2 through a first circuit 6, and the vehicle control unit 3 is in communication connection with the charging device 1 and is arranged to control the charging device 1 to charge the storage battery 2; the storage battery 2 is electrically connected with the vehicle control unit 3 through a second circuit 7, the energy storage timing switch 4 is arranged on the second circuit 7, the vehicle control unit 3 is in communication connection with the energy storage timing switch 4 and is arranged to control the energy storage timing switch 4 to start, wherein the energy storage timing switch 4 is set to be capable of communicating the storage battery 2 and the vehicle control unit 3 under the condition that the energy storage timing switch 4 does not store energy, so that the storage battery 2 supplies power to the vehicle control unit 3, and the energy storage timing switch 4 starts to store energy, the energy storage timing switch 4 can also start to release the stored energy to disconnect the second circuit 7 after receiving a starting instruction of the vehicle controller 3, so that the storage battery 2 stops supplying power to the vehicle controller 3, and the second circuit 7 is connected again and stores the energy again until the energy is released, so as to wait for the next starting instruction.
With continued reference to fig. 1, the power system further includes a third circuit 8, the third circuit 8 is disposed in parallel with the second circuit 7, the energy storage timing switch 4 is disposed on the second circuit 7 and disposed in parallel with the third circuit 8, and a double-throw switch 5 is further disposed at a crossing point of the parallel connection of the second circuit 7 and the third circuit 8. Preferably, as shown in fig. 1, the double-throw switch 5 is in communication connection with the vehicle controller 3, so that the vehicle controller 3 can directly control the on-off mode of the double-throw switch 5, and this scheme is mainly suitable for a vehicle parked for a long time, because the vehicle cannot be wakened in real time when the vehicle controller 3 is in a power-off state, and the double-throw switch 5 needs to be switched to the third circuit 8 when the vehicle controller 3 is in a power-on state. Certainly, the double-throw switch 5 may not be in communication connection with the vehicle controller 3, the double-throw switch 5 is directly and manually controlled, when a vehicle needs to be parked for a long time, a user needs to manually pull the double-throw switch 5 to the second circuit 7, the vehicle can be parked for a long time at this moment, when the vehicle needs to be used, the user manually pulls the double-throw switch 5 to the third circuit 8, the vehicle can be wakened in real time, and accordingly, the step that the user needs to manually operate is introduced.
For the energy storage timing switch 4, it is preferably a mechanical spring switch, wherein the working mode of the mechanical spring switch is as follows: only when the mechanical potential energy stored in the spring is completely released, the timing is completed, and the switch is turned on, which causes a problem: in the process of screwing up the clockwork spring, as long as a little potential energy is stored, the switch is disconnected, the vehicle control unit 3 is powered off, and all energy storage actions of the clockwork spring cannot be finished.
Therefore, the present application proposes several different energy storage timing switches 4 to solve the above technical problem.
Specifically, as shown in fig. 3 and 4, the energy storage timing switch 4 includes an energy storage portion 41 and a switching portion 42 connected to each other, the energy storage portion 41 is configured to store energy when the second circuit 7 is turned on, and the switching portion 42 is configured to receive the energy released by the energy storage portion 41 and thus to turn off the second circuit 7.
In one possible embodiment, as shown in fig. 1 and 3, the energy storage portion 41 is an energy storage spring, the switch portion 42 is a mechanical spring, one end of the first connecting shaft 45 is fixedly connected with the mechanical spring, and the other end of the first connecting shaft is connected with the rotating wheel 44 in a ratchet connection manner, so that when the rotating wheel 44 rotates in the forward direction, the first connecting shaft 45 does not rotate therewith, and when the rotating wheel 44 rotates in the reverse direction, the first connecting shaft 45 rotates therewith and drives the mechanical spring to tighten. An energy storage motor 43 is arranged at the other end of the rotating wheel 44, and the energy storage motor 43 is connected to the rotating wheel 44 through an energy storage motor output shaft 46. A cord 47 is further arranged on the rotating wheel 44, one end of the cord 47 is connected with the rotating wheel 44, the other end of the cord 47 is connected with an energy storage spring, and one end of the energy storage spring, which is far away from the cord 47, is fixedly arranged.
When the second circuit 7 is connected and supplies power to the vehicle control unit 3, the energy storage motor 43 rotates to drive the rotating wheel 44 to rotate in the forward direction, the mechanical spring and the first connecting shaft 45 are not moved, the cord 47 starts to wind on the rotating wheel 44, and the energy storage spring starts to be stretched, so that the energy storage spring stores potential energy until the storage reaches a set value. After the vehicle control unit sends a power-off instruction, the energy storage motor 43 does not provide torque any more, but realizes a free state, the potential energy stored by the energy storage spring is released to drive the rotating wheel 44 to rotate reversely, so that the potential energy stored by the energy storage spring is released into the mechanical spring, the mechanical spring starts timing, the vehicle control unit 3 is powered off, the switch part 42 is closed again until the mechanical spring finishes timing, the second circuit 7 is communicated again, the vehicle control unit 3 supplies power again, and whether the storage battery 2 needs to be charged or not is judged. Through the energy storage mode, the problem that the mechanical spring is difficult to store potential energy can be well solved, reconnection after power failure is realized by utilizing the characteristic that the mechanical spring does not need to continuously supply electric energy, so that the standby time is greatly prolonged, and through practical tests, compared with the existing standby time, a vehicle applying the technology provided by the invention can be prolonged by times.
In another possible embodiment, as shown in fig. 4a and 4b, the energy storage portion 41 includes a capacitor and a push rod assembly (not shown), the switch portion 42 is a mechanical spring, the push rod assembly is connected to the capacitor, and the push rod assembly is configured to convert the electric energy in the capacitor into thrust and transmit the thrust to the switch portion 42 to realize the opening of the switch portion 42. A rack is also provided on the push rod assembly, which is correspondingly engaged with the gear 48, and a second connecting shaft 49 is connected at one end to the switch section 42 and at the other end to the gear 48 in a ratchet connection, so that when the gear 48 is rotated in the forward direction, the second connecting shaft 49 is driven to rotate and thus power the mechanical spring, and when the gear 48 is rotated in the reverse direction, the second connecting shaft 49 is disengaged from the gear 48.
The working principle of the device is similar to that of the previous embodiment, when the second circuit 7 is connected and supplies power to the vehicle control unit 3, the capacitor can store part of electric energy, after the vehicle control unit 3 sends an instruction for starting the switch unit 42, the electric energy of the capacitor is converted into leftward thrust of fig. 4b through the push rod assembly, the gear 48 is driven to rotate forward, the second connecting shaft 49 is driven to rotate, the electric energy of the capacitor is converted into mechanical potential energy and is input into the mechanical spring, the mechanical spring starts to time, the vehicle control unit 3 is powered off, the second connecting shaft 49 cannot conduct the force back to the gear 48 in the potential energy releasing process of the mechanical spring, the electric push rod can also recover to the original position under the action of the reset spring, until the mechanical spring finishes timing, the second circuit 7 is connected again, the vehicle control unit 3 supplies power again, and whether the storage battery 2 needs to be charged or not is judged.
In another possible embodiment, not shown in the figures, the energy storage part 41 is a switch battery, and correspondingly the switch part 42 is an electronic time switch, in this way, it is only necessary to switch the battery to supply power to the electronic time switch, when the second circuit 7 is switched on and supplies power to the vehicle control unit 3, the switch battery stores electric energy, and when the vehicle control unit 3 sends an instruction to turn on the switch portion 42, the switch battery supplies power to the electronic time switch, because the power consumption of the electronic time switch is far less than that of the vehicle controller 3, although the whole standby time is shortened compared with the mechanical spring type scheme, compared with the prior art, the standby time of the whole vehicle can be prolonged, and because the selected parts are all conventional durable parts, the metering of the electronic timing switch is more accurate, and the operation of the electronic timing switch is more stable and is not easy to cause errors.
In the following, taking the double-throw switch 5 in fig. 1 as an example to be controlled by the vehicle controller 3, the overall standby control process of the vehicle is described, and the overall standby control process of the vehicle mainly includes the following steps:
when the vehicle is in a normal standby state, the vehicle controller 3 switches the double-throw switch 5 to the third circuit 8, which is the same as the conventional standby scheme in the prior art;
when the vehicle needs to be in an overlong standby state, the vehicle controller 3 switches the double-throw switch 5 to the second circuit 7, the storage battery 2 supplies power to the vehicle controller 3 at the moment, and meanwhile, the vehicle controller 3 can control the charging device 1 to supply power to the storage battery 2 according to the electric quantity state of the storage battery 2;
when the storage battery 2 supplies power to the vehicle control unit 3, the energy storage part 41 in the energy storage timing switch 4 stores energy through the supply of the storage battery 2, after a power-off instruction of the vehicle control unit 3 is received, the energy storage part 41 supplies the stored energy to the switching part 42 to disconnect the second circuit 7, until the switching part 42 exhausts the energy or the time reaches a set value, the second circuit 7 is reconnected, and the energy storage part 41 restarts storing energy.
While a specific embodiment of the present invention has been described with reference to fig. 1, it should be noted that the above-mentioned embodiments are only used for illustrating the principle of the present invention, and are not intended to limit the protection scope of the present invention, and those skilled in the art can modify the above-mentioned structure so that the present invention can be applied to more specific application scenarios without departing from the principle of the present invention.
For example, in an alternative embodiment, as shown in fig. 2, the double-throw switch 5 can obviously be replaced by two different switches, and the second circuit 7 and the fourth circuit 9 are respectively arranged independently, which is basically the same as the design idea of the double-throw switch 5, and as another example, the vehicle control unit 3 in fig. 2 is not communicatively connected with two different switches, but obviously, the two switches can be controlled to be opened and closed through the communication connection, and these simple modifications do not depart from the principle of the present invention, and thus, the present invention will fall into the protection scope of the present invention.
In summary, the energy storage timing switch 4 is arranged, and the energy storage mechanism of the energy storage part 41 is matched with the mechanical timing mechanism that the spring consumes no power, so that the problem that the standby time is insufficient due to the long-time standby of the vehicle controller 3 in the prior art is solved, and the problem that the vehicle cannot be started normally or the charging device 1 does not charge the storage battery 2 due to the fact that the vehicle controller 3 cannot send a restart instruction in a non-power supply state is solved. The design of the double-throw switch 5 also provides a space for a user to select, so that the vehicle can still continuously stand by in the normal use process, and the stand-by time can be prolonged as far as possible in the idle process. The design is particularly suitable for scenes such as unmanned vehicles and the like which need to manage a plurality of vehicles and have large difference in use requirements of each vehicle, for example, the unmanned vehicles are used for carrying out takeout delivery, the whole delivery system is generally provided with unmanned vehicles with the number larger than the peak period number along with the difference of delivery peaks, a part of the unmanned vehicles with the number larger than the peak period number cannot be started for a long time, the storage battery 2 is empty along with the increase of the standby time, and finally the unmanned vehicles cannot be started.
Finally, it should be noted that although the present invention has been described by taking as an example an electric vehicle and a charging device 1 corresponding thereto as a power battery, it is obvious that the power system for a vehicle of the present invention can also be applied to other vehicles, for example, a fuel vehicle and a charging device 1 corresponding thereto are a fuel engine and a generator connected to each other, the generator being electrically connected to the battery 2 through the first electric circuit 6, and these simple subjects can be reused without departing from the inventive concept of the present invention, and therefore, will fall within the scope of the present invention.
So far, the technical solutions of the present invention have been described in connection with the preferred embodiments shown in the drawings, but it is easily understood by those skilled in the art that the scope of the present invention is obviously not limited to these specific embodiments. Equivalent changes or substitutions of related technical features can be made by those skilled in the art without departing from the principle of the invention, and the technical scheme after the changes or substitutions can fall into the protection scope of the invention.
