Technical Field

[0001] The present application relates to the technical field of vehicles, and in particular to a motorcycle. Background Art

[0002] Motorcycles typically rely on batteries as their power source. When a motorcycle is left unused for an extended period, it's prone to battery depletion, which can cause the vehicle to fail to start or operate properly, shortening the battery's lifespan or even rendering it useless. Therefore, there's a need to address this issue.

[0003] Currently, common battery low-power protection is implemented through software, allowing the vehicle to enter power-saving mode when not in use for a long period of time. However, in power-saving mode, the vehicle still has electrical loads running. For example, some electronic control units (ECUs) will intermittently issue commands to inquire whether to return to normal mode, resulting in continuous power consumption. Utility Model Content

[0023] To make the objectives, technical solutions, and advantages of the embodiments of the present application more clear, the technical solutions in the embodiments of the present application will be clearly and completely described below in conjunction with the accompanying drawings of the embodiments of the present application. Obviously, the described embodiments are only part of the embodiments of the present application, not all of the embodiments. Generally, the components of the embodiments of the present application described and shown in the drawings herein can be arranged and designed in various different configurations.

[0024] Therefore, the following detailed description of the embodiments of the present application provided in the accompanying drawings is not intended to limit the scope of the present application for protection, but merely represents selected embodiments of the present application. All other embodiments obtained by persons of ordinary skill in the art based on the embodiments in the present application without creative work are within the scope of protection of the present application.

[0025] It should be noted that similar reference numerals and letters denote similar items in the following drawings, and therefore, once an item is defined in one drawing, it does not need to be further defined or explained in subsequent drawings.

[0026] The following describes some embodiments of the present application in detail with reference to the accompanying drawings. In the absence of conflict, the following embodiments and features therein may be combined with each other.

[0027] See also Figure 1 , shows a schematic diagram of a motorcycle 100 provided in an embodiment of the present application. The motorcycle 100 includes: a frame 11, a running system 13, a power system 14, an energy storage battery 15 (see Figure 3 ) and control system 160 (refer to Figure 3 ).

[0028] The frame 11 can be used to carry components of the motorcycle 100. In the embodiment of the present application, the motorcycle 100 can further include a body cover 12, which is at least partially disposed on the frame 11 and can be used to cover at least some of the components carried on the frame 11.

[0029] The walking system 13 includes a front wheel 131 and a rear wheel 132, and the front wheel 131 and the rear wheel 132 are arranged below the frame 11. Specifically, the front wheel 131 and the rear wheel 132 can be connected to the frame 11 through a suspension, thereby driving the entire motorcycle 100 to move. It should be understood that the type of the motorcycle 100 in the embodiment of the present application is not particularly limited. For example, it can be a two-wheeled motorcycle with one front wheel and one rear wheel, including but not limited to street cars, cruise cars, touring cars, rally cars, off-road cars, scooters, underbone cars, etc. For another example, it can be a three-wheeled motorcycle with one front wheel and two rear wheels, or a three-wheeled motorcycle with one front wheel and two rear wheels. For another example, it can be a four-wheeled motorcycle with two front wheels and two rear wheels, wherein the four-wheeled motorcycle includes but is not limited to all-terrain vehicles, etc.

[0030] The power system 14 is at least partially arranged on the frame 11 and supported by the frame 11. The power system 14 is transmission-connected to at least one of the front wheel 131 and the rear wheel 132, and the power system 14 can provide power for the motorcycle 100. The energy storage battery 15 is at least partially connected to the frame 11, and can provide electrical energy for the electrical load 16 of the motorcycle 100. The model parameters of the energy storage battery 15 can be selected accordingly according to actual needs. For example, a 12V lead-acid battery or a lithium battery can be used, and no special limitation is made here. In an embodiment of the present application, the power system 14 may include a power motor. The energy storage battery 15 can be connected to the power motor and supply power to the power motor, so that the power motor is powered on and can drive the transmission-connected front wheel 131 and / or rear wheel 132 to rotate.

[0031] It should be understood that the motorcycle 100 referred to in the embodiments of this application can be a pure motorcycle 100, a hybrid electric vehicle (hereinafter referred to as a hybrid electric vehicle), or other types of hybrid vehicles. The specific selection can be made based on actual circumstances and is within the scope of protection of this application. Specifically, when the motorcycle 100 in the embodiments of this application is a hybrid electric vehicle, the power system 14 can also include an engine and a fuel tank mounted on the frame 11. The fuel tank is connected to the engine via an oil line, and the engine is further connected to the power motor. When the fuel tank supplies fuel to the engine, the engine can operate, thereby driving the travel system 13 to rotate independently or in conjunction with the power motor.

[0032] It is understood that the motorcycle 100 may also include other conventional components, such as a dashboard (also referred to as DASH) for displaying vehicle information, a vehicle key 17 (see Figure 3 ) inserted lock cylinder, anti-theft system, radar for assistive driving, and other sensors. Alternatively, motorcycle 100 may combine or disassemble certain components, or employ a different component arrangement. For the sake of brevity, this application does not provide individual examples and descriptions.

[0033] The motorcycle 100's electrical load 16 is at least partially mounted on the frame 11 and includes a control system 160 and its associated electrical components. These components include, but are not limited to, the power system 14, a gateway, a network management node, an anti-theft system, radar, and the like. When powered on, the control system 160 controls the operation of the associated electrical components, thereby controlling the motorcycle 100's operating state and enabling the motorcycle 100 to function appropriately.

[0034] In this embodiment of the present application, the control system 160 includes a first controller 161, multiple second controllers 162, and multiple third controllers 163. The first controller 161, the second controller 162, and the third controller 163 are all electronic control units (ECUs). These ECUs can be connected via a communication bus and each connects to and controls the corresponding electrical components in the motorcycle 100. The first controller 161 is used to control the vehicle's KL15 electrical output and has network management capabilities. For example, the first controller 161 can be a body control module (BCM). The second controller 162 can be a KL30 node controller, such as a motor controller for controlling a power motor, a generator controller for controlling an engine, or a network management node controller. The third controller 163 can be a KL15 node controller, such as a radar controller.

[0035] Figure 2The following diagram shows a circuit connection diagram of an energy storage battery 15 and an electrical load 16 in a common motorcycle 100A. Figure 2 The electrical load 16 in the figure only shows the control system 160 , and does not show the electrical devices connected to the control system 160 .

[0036] like Figure 2 As shown, the first controller 161 and the second controller 162 are currently typically directly connected to the energy storage battery 15, which continuously supplies power to the first controller 161 and the second controller 162. The third controller 163 is connected to the energy storage battery 15 via the first controller 161, and the first controller 161 can control the power supply of the third controller 163.

[0037] When the motorcycle 100A is powered on, it is in normal mode, with all controllers operating and generating power. The operating current of the KL30 node controller is greater than the operating current of the KL15 node controller, so the power consumption of the second controller 162 is greater than the power consumption of the third controller 163.

[0038] When the motorcycle 100A is not used for a long time, the energy storage battery 15 is still continuously supplying power to the first controller 161 and the second controller 162, which may cause the motorcycle 100A to be unable to start or operate normally, shortening the battery life or even causing it to be scrapped.

[0039] Currently, common battery low-power protection is implemented through software, which causes the motorcycle 100A to enter a power-saving mode, such as sleep mode, when not in use for an extended period. However, the second controller 162 continues to operate in power-saving mode, intermittently issuing commands to inquire whether to resume normal mode, resulting in continuous power consumption and the potential for battery low-power issues. For example, assuming a static power consumption of 10mA, a 12V energy storage battery 15 will become low-power after approximately 60 days of discharge.

[0040] Therefore, in order to prevent the energy storage battery 15 from running out of power, Figure 3 As shown, the motorcycle 100 of the embodiment of the present application is additionally provided with a low-voltage control system 18. The low-voltage control system 18 is provided on the frame 11, and the energy storage battery 15 and the electrical load 16 are connected via the low-voltage control system 18.

[0041] Further, Figure 4 A circuit connection diagram of the energy storage battery 15, the low voltage control system 18 and the electrical load 16 in the motorcycle 100 of the present application embodiment is shown. Figure 4 The electrical load 16 in the figure only shows the control system 160 , and does not show the electrical devices connected to the control system 160 . Figure 4 and Figure 2The difference is that Figure 4 The first controller 161 and the second controller 162 of the control system 160 are connected to the energy storage battery 15 through the low-voltage control system 18 .

[0042] Specifically, if Figure 4 As shown, the low-voltage control system 18 is provided with a power input terminal 181, a power output terminal 182, and a negative power terminal 13. The low-voltage control system 18 is connected to the positive terminal of the energy storage battery 15 via the power input terminal 181 to receive power from the energy storage battery 15. The low-voltage control system 18 is also connected to the negative terminal of the energy storage battery 15 via the negative power terminal 13. In this way, the energy storage battery 15 can supply power to the low-voltage control system 18 via the power input terminal 181 and the negative power terminal 13, thereby enabling the low-voltage control system 18 to be powered on and operational. The low-voltage control system 18 is connected to the first controller 161 and the second controller 162 of the control system 160 in the electrical load 16 via the power output terminal 182. The first controller 161 is also connected to the third controller 163. The first controller 161 , the second controller 162 and the third controller 163 are also connected to the negative pole of the energy storage battery 15 . In this way, when the low-voltage control system 18 transmits electrical energy from the energy storage battery 15 , the low-voltage control system 18 can provide electrical energy to the first controller 161 , the second controller 162 and the third controller 163 .

[0043] In addition, to improve safety, protective elements such as fuses can be connected in series between the connected first controller 161 and the third controller 163, between the connected first controller 161 and the power output end 182, and between the connected second controller 162 and the power output end 182.

[0044] The low voltage control system 18 specifically includes a control circuit 184, an execution circuit 185 and a key switch 186. The vehicle key 17 (see Figure 3 ) can be inserted into motorcycle 100 to close key switch 186 and generate a trigger signal. When vehicle key 17 is not inserted into motorcycle 100 or key switch 186 is not closed, key switch 186 cannot generate a trigger signal. Key switch 186 can be any mechanical conductive structure.

[0045] In some embodiments, if the motorcycle 100 is equipped with a lock cylinder, the vehicle key 17 can be inserted into the lock cylinder of the motorcycle 100 to operate the key switch 186, for example, by twisting the key switch 186. In other embodiments, if the motorcycle 100 is a hybrid vehicle and does not have a lock cylinder, the vehicle key 17 can also be inserted into the fuel tank cap of the hybrid vehicle to operate the key switch 186. It should be understood that when the vehicle key 17 is inserted into the motorcycle 100, it indicates that the driver intends to use the motorcycle 100.

[0046] The key switch 186 is connected between the control circuit 184 and a common terminal, and the key switch generates a trigger signal when it is closed. Figure 4 One end of the key switch 186 is connected to the control circuit 184, and the other end is grounded. When the key switch 186 is closed, the key switch 186 generates a low-voltage ground signal, which is the trigger signal. The control circuit 184 can detect the ground signal generated by the key switch 186.

[0047] The control circuit 184 is connected to the positive electrode of the energy storage battery 15 through the power input terminal 181 , and the control circuit 184 can detect the battery voltage of the energy storage battery 15 .

[0048] The control circuit 184 is also connected to the execution circuit 185. In this embodiment of the present application, the execution circuit 185 is provided with an execution switch K. One end of the execution switch K is connected to the positive electrode of the energy storage battery 15 via the power input terminal 181, and the other end of the execution switch K is connected to the power load 16 via the power output terminal 182. In other words, the execution switch K is connected in series between the positive electrode of the energy storage battery 15 and the power load 16. Therefore, the control circuit 184 can control the on / off state of the execution switch K in the execution circuit 185 to control the connection between the energy storage battery 15 and the power load 16.

[0049] Specifically, when the control circuit 184 does not detect a ground signal and detects that the battery voltage of the energy storage battery 15 is equal to or lower than a preset voltage threshold, the control circuit 184 may be configured to output a first control signal to the execution circuit 185. The first control signal is used to control the execution circuit 185 to open the execution switch K. Once the execution switch K is opened, the energy storage battery 15 and the electrical load 16 are disconnected, and the electrical energy of the energy storage battery 15 cannot be transmitted to the electrical load 16, causing the electrical load 16 to lose power and cease operation.

[0050] The preset voltage threshold can be set accordingly according to actual conditions.

[0051] It will be appreciated that when the battery voltage is equal to or lower than the preset voltage threshold, it indicates that the energy storage battery 15 is currently low on charge. Further decreases in charge could result in a risk of battery failure. Therefore, when the control circuit 184 detects no ground signal and detects that the battery voltage of the energy storage battery 15 is equal to or lower than the preset voltage threshold, meaning that there is no current demand for use of the motorcycle 100 and the battery charge is low, the control circuit 184 in this embodiment of the present application controls the actuator switch K to open, thereby de-energizing the electrical load 16. This prevents the load 16 from consuming the energy of the energy storage battery 15 and causing a drop in battery voltage. Consequently, the battery voltage of the energy storage battery 15 can remain constant, i.e., be clamped, thereby preventing the energy storage battery 15 from becoming depleted. Furthermore, this design ensures that the motorcycle 100 can still be started and used normally even if it has been idle for a period of time (i.e., not used for an extended period of time).

[0052] When the control circuit 184 detects a ground signal, it indicates that the motorcycle 100 is currently in use. Therefore, the control circuit 184 can be configured to output a second control signal to the execution circuit 185. This second control signal is a different electrical signal from the first control signal, and the second control signal is used to control the execution circuit 185 to close the execution switch K. Once the execution switch K is closed, the energy storage battery 15 and the electrical load 16 are connected, and the electrical energy of the energy storage battery 15 can be transferred to the electrical load 16, causing the electrical load 16 to be powered and operated. Therefore, the low-voltage control system 18 does not affect the normal use of the motorcycle 100, and the driver can still start and drive the motorcycle 100 normally.

[0053] In some embodiments, when control circuit 184 detects no ground signal and the battery voltage of energy storage battery 15 is above a preset voltage threshold, it indicates that there is no need to use motorcycle 100 and the battery charge is high, posing a low risk of battery depletion. Therefore, control circuit 184 may output a second control signal to execution circuit 185 to close execution switch K. At this point, energy storage battery 15 can supply power to electrical load 16, allowing motorcycle 100 to perform network wake-up, self-diagnosis, and anti-theft functions while stationary (i.e., not in use), thereby improving vehicle safety.

[0054] Thus, the motorcycle 100 of the present embodiment, by adding the hardware structure of the low-voltage control system 18, can automatically disconnect the power to the electrical load 16 when the motorcycle 100 is not in use and the battery charge is low. This prevents the electrical load 16 from consuming battery power and provides low-charge protection for the energy storage battery 15, thereby ensuring vehicle safety and extending the battery life. Furthermore, the low-voltage control system 18 does not affect the driver's normal use of the motorcycle 100.

[0055] In addition, in the embodiment of the present application, after the execution switch K is opened, the control circuit 184 can stop outputting the first control signal, and the execution switch K can be stably maintained in the open state. After the execution switch K is closed, the control circuit 184 can stop outputting the second control signal, and the execution switch K can be stably maintained in the closed state.

[0056] It is understood that the process of the control circuit 184 outputting a control signal consumes a significant amount of power. However, in the embodiment of the present application, the control circuit 184 does not need to continue outputting the first control signal after outputting the first control signal or the second control signal. Therefore, the power consumption of the low-voltage control system 18 in the embodiment of the present application can be very low, further preventing the energy storage battery 15 from running low. Furthermore, the actuator switch K is highly stable and is not easily accidentally closed or opened. Therefore, the low-voltage control system 18 in the embodiment of the present application has high operational stability and reliability, further reducing the risk of the energy storage battery 15 running low.

[0057] For better understanding, the low-voltage control system 18 is further illustrated below with reference to the first and second embodiments.

[0058] Example 1:

[0059] See also Figure 5 , shows a circuit connection diagram of the low-voltage control system 18 of the first embodiment.

[0060] like Figure 5 As shown, the control circuit 184 in the low-voltage control system 18 includes a control chip 1841, a signal detection circuit 1842, and a voltage sampling circuit 1843. The control chip 1841 can be an MCU or other chip with control functions, and the signal detection circuit 1842 and the voltage sampling circuit 1843 can both be any circuit capable of detecting voltage levels.

[0061] The control chip 1841 has a voltage acquisition pin VS, an input pin IN, and two output pins OUT1 and OUT2. The voltage acquisition pin VS of the control chip 1841 is connected to the energy storage battery 15 via a voltage sampling circuit 1843. The input pin IN of the control chip 1841 is connected to a signal detection circuit 1842, which is connected in series with a key switch 186 and grounded via the key switch 186. The output pins OUT1 and OUT2 of the control chip 1841 are both connected to the execution circuit 185.

[0062] The execution circuit 185 in the low-voltage control system 18 includes a first output switch Q1, a second output switch Q2, a first drive switch S1, a second drive switch S2, a drive module 1851, and an execution switch K. The first output switch Q1 and the second output switch Q2 can both be any semiconductor switch tube, such as a MOS tube, an IGBT tube, or a triode, etc. For the convenience of description, Figure 5 In the example, the first output switch Q1 and the second output switch Q2 are both N-channel MOS transistors (hereinafter referred to as NMOS transistors). The first drive switch S1 and the second drive switch S2 can be electromagnetic switches, such as relays or contactors, etc. For the convenience of description, Figure 5 In the example, the first drive switch S1 and the second drive switch S2 are both relays. The drive module 1851 can be a motor, for example, and the execution switch K can be a mechanical switch, such as a connecting rod switch or a knife switch.

[0063] The control end of the first output switch Q1 is connected to the output end OUT1 of the control circuit 184, and the control end of the second output switch Q2 is connected to the output end OUT2 of the control circuit 184. The execution switch K is connected in series between the power input end 181 and the power output end 182, that is, between the positive electrode of the energy storage battery 15 and the power load 16. The output end of the driving module 1851 is connected to the execution switch K.

[0064] The first connection terminal of the first output switch Q1, the first drive switch S1, and the first input terminal of the drive module 1851 are connected in sequence. The first connection terminal of the second output switch Q2, the second drive switch S2, and the second input terminal of the drive module 1851 are connected in sequence. The second connection terminal of the first output switch Q1 and the second connection terminal of the second output switch Q2 are both grounded. The first drive switch S1 and the second drive switch S2 are also connected in parallel between the power input terminal 181 and the execution switch K, that is, between the positive electrode of the energy storage battery 15 and the execution switch K.

[0065] Specifically, if Figure 5As shown, the induction coil of the first drive switch S1 is connected between the first connection terminal of the first output switch Q1 and the power input terminal 181, that is, between the first connection terminal of the first output switch Q1 and the positive terminal of the energy storage battery 15. The contact switch of the first drive switch S1 is connected between the power input terminal 181 and the first input terminal of the drive module 1851, that is, between the positive terminal of the energy storage battery 15 and the first input terminal of the drive module 1851. The static contact of the contact switch is connected to the power input terminal 181 to connect to the positive terminal of the energy storage battery 15, and the movable contact of the contact switch is connected to the first input terminal of the drive module. The contact switch also has a ground contact, which is grounded, and the movable contact is used to select one of the static contact and the ground contact. When the first drive switch S1 is not in operation, the movable contact of the first drive switch S1 can be connected to the ground contact of the first drive switch S1.

[0066] The induction coil of the second drive switch S2 is connected between the first connection terminal of the second output switch Q2 and the power input terminal 181, that is, between the first connection terminal of the second output switch Q2 and the positive electrode of the energy storage battery 15. The contact switch of the second drive switch S2 is connected between the power input terminal 181 and the second input terminal of the drive module 1851, that is, between the positive electrode of the energy storage battery 15 and the second input terminal of the drive module 1851. The static contact of the contact switch is connected to the power input terminal 181 to connect to the positive electrode of the energy storage battery 15, and the moving contact of the contact switch is connected to the second input terminal of the drive module. The contact switch also has a ground contact, which is grounded, and the moving contact is used to select one of the static contact and the ground contact. When the second drive switch S2 is not working, the moving contact of the second drive switch S2 can be connected to the ground contact of the second drive switch S2.

[0067] Based on this design, the control chip 1841 can be used to detect the battery voltage through the voltage sampling circuit 1843 and the ground signal through the signal detection circuit 1842. When the ground signal is not detected and the battery voltage of the energy storage battery 15 is equal to or lower than the preset voltage threshold, the control chip 1841 can be used to generate a first control signal and output it to the first output switch Q1 and the second output switch Q2. When the ground signal is detected, the control chip 1841 can be used to generate a second control signal and output it to the first output switch Q1 and the second output switch Q2. Under the control of the first control signal or the second control signal, one of the first output switch and the second output switch is selectively turned on, where the output switch turned on by the first control signal is different from the output switch turned on by the second control signal.

[0068] For example, the first control signal is used to drive the first output switch Q1 to turn off and the second output switch Q2 to turn on. When the second output switch Q2 is turned on, the positive electrode of the energy storage battery 15, the induction coil of the second drive switch S2, the second output switch Q2, and the ground are connected to form a conductive path, energizing the induction coil of the second drive switch S2 and generating an electromagnetic signal. This electromagnetic signal can be used to drive the movable contact and the static contact of the second drive switch S2 to attract together, allowing the contact switch to transmit electrical energy from the energy storage battery 15 to the second input terminal of the drive module 1851. At the same time, because the first output switch Q1 is turned off, the induction coil of the first drive switch S1 cannot be energized to generate an electromagnetic signal. Consequently, the movable contact and the static contact of the first drive switch S1 cannot be attracted together, and thus, the electrical energy from the energy storage battery 15 cannot be transmitted to the first input terminal of the drive module 1851. Therefore, the movable contact of the first drive switch S1 remains connected to the ground contact.

[0069] That is to say, the second drive switch S2 can be connected when the second output switch Q2 is turned on, and supply power to the second input end of the drive module 1851. The first drive switch S1 cannot be connected when the first output switch Q1 is disconnected, resulting in the inability to supply power to the first input end of the drive module 1851. The first input end of the drive module 1851 is grounded at this time.

[0070] When the second input terminal of the drive module 1851 is powered and the first input terminal of the drive module 1851 is grounded (or unpowered), the drive module 1851 can drive the actuator switch K to rotate in a first rotational direction, thereby switching the actuator switch K to an off state, thereby disconnecting the positive electrode of the energy storage battery 15 from the power load 16. As a result, the energy storage battery 15 cannot output power to the power load 16 via the low-voltage control system 18. The power load 16 cannot be powered on and cannot consume power from the energy storage battery 15. As a result, the battery voltage can remain unchanged and will not continue to drop, thereby preventing the energy storage battery 15 from entering a power-deficient state.

[0071] For another example, the second control signal is used to drive the first output switch Q1 to conduct and the second output switch Q2 to disconnect. When the first output switch Q1 is on, the positive electrode of the energy storage battery 15, the induction coil of the first drive switch S1, the first output switch Q1, and ground are connected to form a conductive path, energizing the induction coil of the first drive switch S1 and generating an electromagnetic signal. This electromagnetic signal can be used to drive the movable contact and the static contact of the contact switch of the first drive switch S1 to close together, allowing the contact switch to transmit electrical energy from the energy storage battery 15 to the first input terminal of the drive module 1851. At the same time, because the second output switch Q2 is disconnected, the induction coil of the second drive switch S2 cannot be energized to generate an electromagnetic signal. Consequently, the movable contact and the static contact of the second drive switch S2 cannot be attracted together, and thus, the electrical energy from the energy storage battery 15 cannot be transmitted to the second input terminal of the drive module 1851. Therefore, the movable contact of the first drive switch S1 remains connected to the ground contact.

[0072] That is to say, the first drive switch S1 can be connected when the first output switch Q1 is turned on, and power can be supplied to the first input end of the drive module 1851. The second drive switch S2 cannot be connected when the second output switch Q2 is turned off, resulting in the inability to supply power to the second input end of the drive module 1851. The second input end of the drive module 1851 is grounded at this time.

[0073] Furthermore, when the first input terminal of the drive module 1851 is powered and the second input terminal of the drive module 1851 is grounded (or unpowered), the drive module 1851 can drive the actuator switch K to rotate in the second rotational direction, switching the actuator switch K to a closed state, thereby connecting the positive terminal of the energy storage battery 15 to the electrical load 16. In this way, the energy storage battery 15 can output electrical energy to the electrical load 16, which can be powered and operated, allowing the motorcycle 100 to be used. The first rotational direction is opposite to the second rotational direction. For example, the first rotational direction is the reverse direction and the second rotational direction is the forward direction, or vice versa.

[0074] In addition, in some embodiments, the control chip 1841 can also be used to generate a second control signal and output it to the first output switch Q1 and the second output switch Q2 when no ground signal is detected and the battery voltage of the energy storage battery 15 is detected to be higher than a preset voltage threshold, so that the motorcycle 100 can obtain power when not in use to maintain network wake-up, self-test, anti-theft and other functions.

[0075] In some embodiments, as Figure 5 As shown, the control chip 1841 may further include a clock pin CLK. The clock pin CLK of the control chip 1841 is connected to a timer 1844. The timer 1844 may be any circuit or module having a timing function.

[0076] The control chip 1841 can be used to time the duration of time that the battery voltage of the energy storage battery 15 is equal to or lower than the corresponding preset voltage threshold through the timer 1844, and generate a first control signal when the ground signal of the control chip 1841 is not detected and the timing duration of the timer 1844 reaches the corresponding preset timing threshold. The control chip 1841 can also be used to time the duration of time that the battery voltage of the energy storage battery 15 is higher than the preset voltage threshold through the timer 1844, and generate a second control signal when the ground signal of the control chip 1841 is not detected and the timing duration of the timer 1844 reaches the corresponding preset timing threshold. This design can ensure the voltage state of the energy storage battery 15 is stable and avoid erroneous control due to battery voltage jitter. Among them, the preset timing threshold can be set accordingly according to actual conditions and is not specifically limited here.

[0077] In some embodiments, as Figure 5 As shown, the first connection end of the first output switch Q1 can also be connected in series with a current-limiting resistor R to limit the current on the first input end of the first output switch Q1, and the first connection end of the second output switch Q2 can also be connected in series with a current-limiting resistor to limit the current on the first input end of the second output switch Q2, thereby improving the device safety of the execution circuit 185.

[0078] It is understandable that Figure 5 The pin numbers of the control chip 1841 shown in FIG are only examples and do not constitute a specific limitation on the embodiments of the present application. In actual applications, other pin numbers can also be used to implement Figure 5 The functions of the pins shown in FIG. 1 and FIG. 2 are exemplary embodiments of the present invention. Alternatively, the control chip 1841 may further include more pins. In other embodiments, Figure 5 The hardware circuit shown can also be adaptively adjusted according to actual conditions. For example, at least one of the signal detection circuit 1842, the voltage sampling circuit 1843, and the timer 1844 can be integrated into the control chip 1841 without having to be separately provided.

[0079] In general, the low-voltage control system 18 of this embodiment is mainly composed of components such as a control chip 1841, a signal detection circuit 1842, a voltage sampling circuit 1843, a first output switch Q1, a second output switch Q2, a first drive switch S1, a second drive switch S2, a drive module 1851 and an execution switch K. Obviously, the low-voltage control system 18 of this embodiment has a simple structure and is easy to implement.

[0080] Moreover, in the low-voltage control system 18 of this embodiment, the output terminal OUT1 of the control chip 1841, the first output switch Q1 and the first drive switch S1 constitute one drive path of the drive module 1851, and the output terminal OUT2 of the control chip 1841, the second output switch Q2 and the second drive switch S2 constitute another drive path of the drive module 1851. The two drive paths can accurately control the direction of the drive module 1851, thereby accurately controlling the on-off state of the execution switch K.

[0081] The signal output by the control chip 1841 is typically a relatively low voltage signal. Since the first output switch Q1 and the second output switch Q2 in this embodiment utilize semiconductor switching transistors, which have an amplification function, the control chip 1841 can use these semiconductor switching transistors to provide the required, high power output to the first drive switch S1 and the second drive switch S2, thereby effectively controlling the first drive switch S1 and the second drive switch S2. When the first output switch Q1 and the second output switch Q2 utilize NMOS transistors, NMOS transistors have low on-resistance, fast switching speed, and can provide relatively high output current, which facilitates driving the first drive switch S1 and the second drive switch S2.

[0082] In this embodiment, the first drive switch S1 and the second drive switch S2 utilize electromagnetic switches. Electromagnetic switches can withstand high currents and voltages and maintain a stable on / off state. Therefore, they can stably and safely power the drive module 1851, facilitating stable and safe operation of the drive module 1851. In this embodiment, the actuator switch K is driven by the drive module 1851. Because the drive module 1851 utilizes a motor connected to the actuator switch K via the motor output shaft, which does not rebound and reset, control jitter can be avoided, improving the accuracy of power output control. Therefore, the low-voltage control system 18 of this embodiment operates with high reliability and stability.

[0083] During the control process, control chip 1841 does not need to continuously output control signals to maintain the electromagnetic switch on and off and the drive module 1851 in its rotational direction. Therefore, the power consumption of control chip 1841 is also relatively low. Compared to the practice of putting motorcycle 100 into hibernation to reduce the risk of power failure, after the low-voltage control system 18 disconnects the electrical load 16, the power consumption of motorcycle 100 is significantly reduced, greatly reducing the risk of power failure.

[0084] Example 2:

[0085] See also Figure 6 , shows a circuit connection diagram of the low-voltage control system 18 of the second embodiment.

[0086] The difference between the second embodiment and the first embodiment lies in the execution circuit 185. Specifically, the execution circuit 185 of the second embodiment includes a first output switch Q1, a second output switch Q2, a driving module 1851 and an execution switch K, while the first driving switch S1 and the second driving switch S2 of the first embodiment are omitted.

[0087] like Figure 6 As shown, the first connection end of the first output switch Q1 is connected to the first input end of the driving module 1851, and the first connection end of the second output switch Q2 is connected to the second input end of the driving module 1851. The contents of other components of the second embodiment can refer to the relevant description of the first embodiment, and will not be repeated here.

[0088] Based on this design, when the first output switch Q1 is on, it can directly supply power to the first input terminal of the driving module 1851. However, the second output switch Q2 is off, preventing it from supplying power to the second input terminal of the driving module 1851. Therefore, when the first input terminal of the driving module 1851 is powered but the second input terminal is not, the driving module 1851 can drive the actuator switch K to rotate in the second rotational direction, switching the actuator switch K to a closed state, thereby connecting the positive electrode of the energy storage battery 15 to the electrical load 16. In this way, the energy storage battery 15 can output electrical energy to the electrical load 16, allowing the motorcycle 100 to be used.

[0089] When the second output switch Q2 is on, it can directly supply power to the second input terminal of the driver module 1851. However, the first output switch Q1 is off, preventing it from supplying power to the first input terminal of the driver module 1851. Therefore, when the second input terminal of the driver module 1851 is powered but the first input terminal is not, the driver module 1851 can drive the actuator switch K to rotate in the first rotational direction, switching the actuator switch K to the off state. This disconnects the positive electrode of the energy storage battery 15 from the electrical load 16. This prevents the electrical load 16 from consuming energy from the energy storage battery 15, thereby clamping the battery voltage and preventing the energy storage battery 15 from entering a low-power state.

[0090] It can be understood that the low-voltage control system 18 of the second embodiment has a simple structure and is easy to implement. In addition, it has fewer components and thus has a lower cost.

[0091] Furthermore, in this embodiment, the first output switch Q1 and the second output switch Q2 can be implemented as semiconductor switches, which have an amplification function. Therefore, the control chip 1841 can use the semiconductor switches to provide the required, high power output to the driver module 1851, thereby effectively controlling the operation of the driver module 1851. When the first output switch Q1 and the second output switch Q2 are implemented as NMOS transistors, NMOS transistors have low on-resistance, fast switching speed, and can provide high output current, which facilitates driving the driver module 1851.

[0092] It should be understood that the other contents of the second embodiment can refer to the relevant description of the first embodiment, so they will not be repeated here.

[0093] In other embodiments, the control circuit 184 and the execution circuit 185 may also adopt other circuit structures, as long as the control circuit 184 and the execution circuit 185 can achieve the corresponding functions, and no further examples are given here.

[0094] It is understandable that, in addition to the low battery voltage caused by the continuous power consumption of the electrical load 16 when the motorcycle 100 is idle, when the battery voltage is low due to other reasons (such as capacity decay and reduced discharge capacity after long-term use of the battery), the motorcycle 100 can, when the motorcycle 100 is not being driven and the battery voltage is low, cut off the power supply of the energy storage battery 15 to the electrical load 16 through the above-mentioned low-voltage control system 18, thereby avoiding the energy storage battery 15 from being depleted due to the battery voltage drop caused by the power consumption of the electrical load 16, thereby achieving power-down protection for the energy storage battery 15.

[0095] The above embodiments are described in the form of preferred embodiments of the present application and are not intended to limit the scope of the present application. Without departing from the design spirit of the present application, various modifications and improvements made to the technical solutions of the present application by ordinary technicians in this field should fall within the scope of protection determined by the claims of the present application.
