Description

Technical Field

[0001] The present application relates to the technical field of electric scooters, and in particular to an integrated button control system for an electric scooter and an electric scooter. Background Art

[0002] With growing environmental awareness and technological advancements, low-carbon living and green travel are becoming increasingly popular topics. Various green mobility devices, such as balance bikes, unicycles, electric scooters, electric bicycles, and electric motorcycles, have emerged. Among them, electric scooters, with their advantages of portability and ease of operation, have gradually become a popular short-distance mobility device, with broad potential for future development.

[0003] Electric scooters are usually equipped with operating buttons for functions such as power on and off, lighting operation, mode switching, and display data switching. Traditional electric scooters often use multiple independent control buttons for these functions, each of which is responsible for a different function.

[0004] However, this decentralized button method has the following problems: first, a corresponding button circuit needs to be added for each button, which has a low integration level, not only taking up the limited space of the scooter, but also increasing the cost; second, the user needs to frequently operate different buttons during operation, which reduces the convenience of use and the user experience is poor. Utility Model Content

[0005] In response to the problems existing in the decentralized buttons of electric scooters, the present application provides an integrated button control system for an electric scooter and an electric scooter.

[0009] By adopting the above technical solution, by integrating multiple functions of the electric scooter into one adjustment button SW1, the main control can sense in real time through the button module whether the user operates the adjustment button SW1 for a long time or a short press, as well as the number of short presses; thereafter, the main control can directly control the operating state of the electric scooter according to the user's operation of the adjustment button SW1, and can also send a prompt sound through the buzzer module, display corresponding data through the display screen, and light up the corresponding light through the light control module. The one-button multi-function multiplexing design of the adjustment button SW1 solves the problems existing in the decentralized buttons, improves the system integration, reduces the space occupation and cost of the scooter, and eliminates the need for users to frequently operate different buttons, thereby improving the convenience of use and user experience.

[0065] In order to enable those skilled in the art to better understand the technical solutions in this specification, the technical solutions in the embodiments of this specification will be clearly and completely described below in conjunction with the drawings in the embodiments of this specification. Obviously, the described embodiments are only part of the embodiments of this application, not all of the embodiments.

[0066] In the description of the embodiments of this application, words such as "for example" or "for instance" are used to indicate examples, illustrations, or explanations. Any embodiment or design described as "for example" or "for instance" in the embodiments of this application should not be construed as being preferred or advantageous over other embodiments or designs. Rather, the use of words such as "for example" or "for instance" is intended to present the relevant concepts in a concrete manner.

[0067] The embodiment of the present application provides an integrated button control system for an electric scooter, such as Figure 1 As shown, the system includes a main control 1, a button module 2, a buzzer module 3, a display screen 4 and a light control module 5; the button module 2 includes an adjustment button SW1;

[0068] The main control 1 is connected to the button module 2, the buzzer module 3, the display screen 4 and the light control module 5 respectively;

[0069] The main control 1 is used to sense the user's pressing operation on the adjustment button SW1 through the button module 2, and perform one or more operations of controlling the running state of the electric scooter, controlling the buzzer module 3 to emit a button prompt sound, controlling the display screen 4 to display data, and controlling the light control module 5 to light up the corresponding light; wherein the pressing operation includes long pressing and short pressing.

[0070] Therefore, by integrating multiple functions of the electric scooter into one adjustment button SW1, the main control 1 can sense in real time through the button module 2 whether the user operates the adjustment button SW1 for a long time or a short press, as well as the number of short presses; thereafter, the main control 1 can directly control the operating state of the electric scooter according to the user's operation of the adjustment button SW1, and can also send a prompt sound through the buzzer module 3, display corresponding data through the display screen 4, and light up the corresponding light through the light control module 5, etc. The one-button multi-function multiplexing design of the adjustment button SW1 solves the problems existing in the decentralized buttons, improves the system integration, reduces the space occupied and cost of the scooter, and eliminates the need for users to frequently operate different buttons, thereby improving the convenience of use and user experience.

[0071] For example, when the user long presses or short presses SW1, a key prompt sound is emitted through the buzzer module 3; when the user long presses SW1, indicating power on / off, the display screen 4 is controlled to power on or off, and display or not display data; when the user short presses SW1 once, the light control module 5 is controlled to light up the headlights of the electric scooter; when the user short presses SW1 twice, the mileage display mode on the display screen 4 is switched to kilometers and miles; when the user short presses SW1 three times, the electric scooter is controlled to turn on or off cruise control, etc. Those skilled in the art can design these as they wish, and they are not specifically limited here.

[0072] In one possible implementation, Figure 2 As shown, the key module 2 includes a resistor R1, a resistor R2, a resistor R3, a resistor R4, a transistor Q1, a diode D1 and a diode D2;

[0073] The first end of the resistor R1 is connected to the main control 1, and the second end is connected to the control end of the transistor Q1 and the first end of the resistor R2 respectively; the first end of the transistor Q1 is connected to the anode of the diode D2 and the main control 1 respectively; the second end of the transistor Q1 and the second end of the resistor R2 are grounded;

[0074] The cathode of the diode D2 is connected to the adjustment button SW1 and then grounded; the cathode of the diode D1 is connected to the middle node between the diode D2 and the adjustment button SW1, and the anode is connected to the 5V power supply through the resistor R3. The anode of the diode D1 is also connected to the main control 1 through the resistor R4.

[0075] The main control 1 is used to determine whether the user has pressed the adjustment button SW1 by detecting the voltage at one end where the main control 1 is connected to the diode D2 and the voltage at one end where the main control 1 is connected to the resistor R4.

[0076] The following is an explanation of the working process of this module:

[0077] When the main control 1 detects that the voltage at one end where the main control 1 and the diode D2 are connected is at a low level and lasts for a first preset time, the main control 1 determines that the user has long pressed the adjustment button SW1. At this time, the main control 1 controls the display screen 4 to power on or off. After controlling the display screen 4 to power on, the main control 1 also controls the transistor Q1 to conduct, so that the voltage at one end where the main control 1 and the diode D2 are connected remains at a low level, thereby keeping the display screen 4 powered on.

[0078] When the main control 1 detects that the voltage at one end where the main control 1 and the resistor R4 are connected is at a low level and the low level lasts for a second preset time, the main control 1 determines that the user has short-pressed the adjustment button SW1 once, and the main control 1 controls the light control module 5 to light up or turn off the headlight of the electric scooter;

[0079] When the main control 1 detects twice in succession that the voltage at the terminal connected to the main control 1 and the resistor R4 is at a low level, and each low level lasts for a second preset time, the main control 1 determines that the user has short-pressed the adjustment button SW1 twice, and the main control 1 controls the display screen 4 to switch the mileage display mode to kilometers and miles.

[0080] When the main control 1 detects three times that the voltage at one end where the main control 1 is connected to the resistor R4 is at a low level, and each low level lasts for a second preset time, the main control 1 determines that the user has short-pressed the adjustment button SW1 three times. At this time, the main control 1 controls the electric scooter to turn on or off cruise control.

[0081] Therefore, by designing the relevant circuits involved in the adjustment button SW1 in the button module 2, the main control 1 can sense the user's operation in real time by detecting the voltages of the two nodes.

[0082] In one possible implementation, continue to refer to Figure 2, the button module 2 further includes a left turn signal button SW2, a right turn signal button SW3, a resistor R5, a resistor R6, a resistor R7 and a resistor R8;

[0083] Among them, one end of the left turn signal button SW2 is connected to the main control 1 through the resistor R5, and the other end is grounded; one end of the resistor R7 is connected to the middle node between the left turn signal button SW2 and the resistor R5, and the other end is connected to the 5V power supply;

[0084] One end of the right turn signal button SW3 is connected to the main control 1 through the resistor R6, and the other end is grounded; one end of the resistor R8 is connected to the middle node between the right turn signal button SW3 and the resistor R6, and the other end is connected to a 5V power supply;

[0085] The main control 1 is used to determine whether the user has pressed the left turn signal button SW2 by detecting the voltage at one end connected to the main control 1 and the resistor R5, and to control the light control module 5 to light up the left turn signal of the electric scooter;

[0086] The main control 1 is used to determine whether the user has pressed the right turn signal button SW3 by detecting the voltage at one end connected to the main control 1 and the resistor R5, and to control the light control module 5 to light up the right turn signal of the electric scooter.

[0087] Those skilled in the art can understand that the resistor R5 and the resistor R7 constitute a voltage divider circuit of the left turn signal button SW2 , and the resistor R5 and the resistor R8 constitute a voltage divider circuit of the right turn signal button SW3 .

[0088] In the button module 2, based on the user's usage habits, two buttons are separately designed for the turn signal, as well as a voltage divider circuit that is convenient for the main control 1 to detect. When the user presses the left turn signal button SW2 or the right turn signal button SW3, the main control 1 detects the voltage of the corresponding node, which is different from when it is not pressed, and can determine the user's operation.

[0089] In one possible implementation, Figure 3 As shown, the buzzer module 3 includes a resistor R9, a resistor R10, a transistor Q2, a diode D3 and a buzzer;

[0090] The control end of the transistor Q2 is connected to the main control 1 through the resistor R9; the intermediate node between the transistor Q2 and the resistor R9 is grounded through the resistor R10; the first end of the transistor Q2 is connected to a 5V power supply through the diode D3, and the buzzer is connected in parallel at both ends of the diode D3; the second end of the transistor Q2 is grounded;

[0091] The main control 1 is used to control the transistor Q2 to conduct when the user presses the adjustment button SW1, so that the 5V power supply, the buzzer and the transistor Q2 form a current path, and the buzzer emits a key prompt sound.

[0092] It is understandable that the resistors R9 and R10 are used to configure the conduction current of the transistor Q2. By designing the buzzer module 3, when the user operates the adjustment button SW1, a prompt sound is emitted through the buzzer, thereby improving the user experience.

[0093] In one possible implementation, Figure 1 and Figure 4 As shown, the lighting control module 5 includes a headlight control submodule 51; the headlight control submodule 51 includes a resistor R11, a resistor R12, a resistor R13, a resistor R14, a resistor R15, a resistor R16, a resistor R17, a transistor Q3, a switch Q4, a transistor Q5, a diode D4, an inductor L1, a capacitor C1 and a headlight;

[0094] The control end of the transistor Q3 is connected to the main control 1 through the resistor R12; the first end of the transistor Q3 is connected to the first end of the resistor R11 and the control end of the switch Q4 respectively; the second end of the transistor Q3 is grounded through the resistor R13;

[0095] The second end of the resistor R11 is connected to the first end of the switch Q4, which is also connected to a 12V power supply. The second end of the switch Q4 is connected to the first end of the headlight via the inductor L1. The cathode of the diode D4 is connected to the middle node between the switch Q4 and the inductor L1, and the anode is grounded. One end of the capacitor C1 is connected to the middle node between the inductor L1 and the headlight, and the other end is grounded.

[0096] The second end of the headlight is grounded via the resistor R17, and the second end of the headlight is also connected to the control end of the transistor Q5 via the resistor R16; the first end of the transistor Q5 is connected to the middle node between the transistor Q3 and the resistor R12, the first end of the resistor R14 is connected to the middle node between the transistor Q3 and the resistor R12, and the first end of the resistor R15 is connected to the middle node between the transistor Q5 and the resistor R16;

[0097] The second end of the resistor R15, the second end of the transistor Q5 and the second end of the resistor R14 are all grounded;

[0098] The main control 1 is used to drive the transistor Q3 to turn on, so that the switch tube Q4 is turned on. Then, the 12V power supply, the switch tube Q4, the inductor L1, the headlight and the resistor R17 form a current path, so that the headlight is powered on and lights up; the transistor Q5 is used to turn on when the current of the headlight exceeds the current threshold, so that the transistor Q3 is turned off to prevent overcurrent of the headlight.

[0099] It can be understood that the resistor R17 is used to limit current to prevent excessive current from flowing through the headlights; the resistor R16 and the resistor R15 are used to configure the on-current of the transistor Q5, the resistor R12 and the resistor R14 are used to configure the on-current of the transistor Q3, the resistor R11 and the resistor R13 are used to configure the on-current and current limiting of the switch tube Q4, and the diode D4, the inductor L1 and the capacitor C1 constitute a step-down circuit.

[0100] Therefore, through the design of the headlight control submodule 51, when the headlights need to be controlled to light up, the main control 1 drives the transistor Q3 to turn on; at the same time, the module is also designed with a circuit structure with a protection function, which can avoid overcurrent of the headlights and improve safety.

[0101] In one possible implementation, Figure 1 and Figure 5 As shown, the light control module 5 further includes a turn signal control submodule 52;

[0102] The turn signal control submodule 52 includes a resistor R18, a resistor R19, a resistor R20, a resistor R21, a resistor R22, a resistor R23, a transistor Q6, a transistor Q7, a left turn signal and a right turn signal;

[0103] The control end of the transistor Q6 is connected to the main control 1 through the resistor R18, one end of the resistor R19 is connected to the middle node between the transistor Q6 and the resistor R18, and the other end is grounded; the first end of the transistor Q6 is connected to the first end of the left turn signal lamp, and the second end is grounded;

[0105] After the resistor R22 and the resistor R23 are connected in parallel, one end is connected to a 12V power supply, and the other end is connected to the second end of the left turn signal lamp and the second end of the right turn signal lamp respectively;

[0106] The main control 1 is used to drive the transistor Q6 to conduct, so that the 12V power supply, the resistor R22, the resistor R23, the left turn signal lamp and the transistor Q6 form a current path, so that the left turn signal lamp lights up;

[0107] The main control 1 is further configured to drive the transistor Q7 to conduct, so that the 12V power supply, the resistor R22 , the resistor R23 , the right turn signal light and the transistor Q7 form a current path, thereby turning on the right turn signal light.

[0108] It can be understood that the resistors R18 and R19 are used to configure the on-current of the transistor Q6; the resistors R20 and R21 are used to configure the on-current of the transistor Q7; and the resistors R22 and R23 are used for current limiting to configure the operating current of the left turn signal and the right turn signal.

[0109] Therefore, through the design of the turn signal control submodule 52, when the turn signal needs to be controlled to light up, the main control 1 only needs to drive the transistor Q6 or Q7 to turn on.

[0110] In one possible implementation, Figure 6 As shown, the system further includes a speed regulating module 6; the speed regulating module 6 includes a first Hall sensor, a second Hall sensor, a resistor R24, a resistor R25, a resistor R26, a resistor R27, a capacitor C2 and a capacitor C3;

[0112] The signal output end of the second Hall sensor is connected to the main control 1 through the resistor R26, one end of the resistor R27 is connected to the middle node between the resistor R26 and the main control 1, and the other end is grounded; one end of the capacitor C3 is connected to the middle node between the resistor R26 and the second Hall sensor, and the other end is connected to the grounded end of the resistor R27;

[0113] The first Hall sensor is used to detect the rotation angle of the accelerator handle of the electric scooter and output a corresponding voltage through the signal output terminal; the main control 1 is used to determine the rotation angle of the accelerator handle and adjust the speed of the electric scooter by detecting the voltage at one end of the main control 1 connected to the resistor R24;

[0114] The second Hall sensor is used to detect the rotation angle of the brake handle of the electric scooter and output the corresponding voltage through the signal output end; the main control 1 is used to determine the rotation angle of the brake handle and adjust the speed of the electric scooter by detecting the voltage at one end of the main control 1 connected to the resistor R26.

[0115] Those skilled in the art will appreciate that the resistor R24 ​​and the resistor R25 form a voltage divider circuit, and the capacitor C2 is used for filtering; the resistor R26 and the resistor R27 form a voltage divider circuit, and the capacitor C3 is used for filtering.

[0116] Therefore, through the design of the speed adjustment module 6, the main control 1 can accurately obtain the user's operation of the accelerator handle and the brake handle, and adjust the speed of the electric scooter accordingly.

[0117] In one possible implementation, Figure 1 and Figure 7 As shown, the system further includes a communication module 7; the communication module 7 is connected between the main control 1 and the display screen 4; the voltage standards of the main control 1 and the display screen 4 are different, and the communication module 7 is used to realize signal transmission between the main control 1 and the display screen 4 through voltage conversion;

[0119] The signal receiving end of the main control 1 is connected to the signal sending end of the display screen 4 through the resistor R29; one end of the resistor R28 is connected to the middle node between the signal receiving end of the main control 1 and the resistor R29, and the other end is grounded; one end of the capacitor C4 is connected to the signal receiving end of the main control 1 and the middle node between the resistor R29, and the other end is grounded;

[0120] The signal sending end of the main control 1 is connected to the control end of the transistor Q8 through the resistor R30. The first end of the transistor Q8 is connected to the 5V power supply through the resistor R33, and the second end is grounded. One end of the resistor R31 is connected to the middle node between the signal sending end of the main control 1 and the resistor R30, and the other end is connected to the middle node between the resistor R33 and the 5V power supply. One end of the resistor R32 is connected to the middle node between the transistor Q8 and the resistor R30, and the other end is grounded.

[0121] The control end of the transistor Q9 is connected to the first end of the transistor Q8, the first end of the transistor Q9 is connected to the 5V power supply through the resistor R34, and the second end is grounded; the first end of the transistor Q9 is also connected to the signal receiving end of the display screen 4; one end of the capacitor C5 is connected to the middle node between the first end of the transistor Q9 and the signal receiving end of the display screen 4, and the other end is grounded;

[0122] The communication module 7 is used to convert the 3.3V voltage signal output by the signal sending end of the main control 1 into a 5V voltage signal and output it to the signal receiving end of the display screen 4; the communication module 7 is also used to convert the 5V voltage signal output by the signal sending end of the display screen 4 into a 3.3V voltage signal and output it to the signal receiving end of the main control 1.

[0123] It will be understood by those skilled in the art that, when the signal transmitting end of the main control 1 outputs a 3.3V voltage signal, transistors Q8 and Q9 are turned on, so that the voltage at the signal receiving end of the display screen 4 is 5V; when the signal transmitting end of the display screen 4 outputs a 5V voltage signal, the voltage at the signal receiving end of the main control 1 is 3.3V through the voltage division of resistors R28 and R29; capacitors C4 and C5 are used for filtering.

[0124] Therefore, when the voltage standards of the main control 1 and the display screen 4 are different, that is, when the identifiable voltages are different, the voltage conversion of the communication module 7 is used to ensure normal communication between the two.
