[0002] As people's living standards improve, unicycles, as a convenient means of transportation, are increasingly favored by consumers. However, the current locking and unlocking methods of unicycles are simple. They need to be manually locked after the unicycle is parked, and after locking, a password needs to be re-entered or a key needs to be used to unlock it. Moreover, the unlocking process is relatively complicated, and it is not possible to flexibly switch between unlocking methods in daily use scenarios and scenarios that require quick unlocking. Utility Model Content

[0003] In order to overcome the shortcomings of the existing technology, this utility model provides a locking device and a unicycle to solve the problems of cumbersome operation and poor adaptability in the unicycle unlocking process.

[0004] One embodiment of this utility model provides a vehicle locking device electrically connected to a hub motor. The hub motor is installed under the vehicle body and is used to drive the vehicle body to move. The vehicle locking device includes:

[0005] A processor, installed inside the vehicle body, is used to output control signals to adjust the locking and unlocking states of the wheel hub motors;

[0007] A sensor assembly, which is electrically connected to the processor;

[0008] The switch has several preset input positions. When the hub motor is unlocked, the switch and the processor are configured to control the hub motor to enter the locked state in a preset mode.

[0009] In one embodiment of this utility model, the processor is electrically connected to the battery module; the battery module is a storage battery installed on the control panel or a storage battery in the vehicle body used to drive the hub motor.

[0010] In one embodiment of this utility model, the input module uses any one or more of physical buttons, numeric keypads, or touchpads to input a lock command or password to the processor, so that the hub motor enters a lock state or an unlock state.

[0040] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments. Based on the embodiments of the present utility model, all other embodiments obtained by those of ordinary skill in the art without creative effort are within the protection scope of the present utility model.

[0041] In existing technologies, unicycles are widely used as a convenient means of transportation, but traditional locks have the problem of cumbersome operation; users need to manually operate the physical lock and repeatedly enter the password or use the key when unlocking, which cannot adapt to different scenario needs; for example, when it is necessary to quickly lock the vehicle during a short stop, existing technologies can only complete this through complicated steps, affecting the efficiency of use.

[0042] To address the aforementioned issues, a vehicle locking device that simplifies the operation process and supports multiple unlocking methods needs to be designed. Considering the varying needs of users in different scenarios, the key lies in integrating multiple control methods and enabling rapid switching. By analyzing user operating habits, it was found that the combination of physical buttons and touch input can balance operational efficiency and security. At the same time, the status prompt function can effectively prevent accidental operation and ensure the reliability of the vehicle locking status.

[0043] Therefore, please refer to Figures 1-4 This application proposes a processor 3 installed inside the vehicle body 1 for adjusting the locking and unlocking states of the hub motor 2; a control panel 4 installed on the outer surface of the vehicle body 1, integrating a display screen 5, an input module 6, and a switch 7; the locking device also includes a sensor assembly 10, which is electrically connected to the processor 3, and the switch 7 has multiple preset input positions, which control the hub motor 2 to enter the locking state according to the preset mode when the hub motor 2 is unlocked.

[0044] Among them, processor 3 refers to an electronic control unit with logic operation capabilities, which can be implemented using a microcontroller or programmable logic device, used to receive input signals and generate corresponding motor control commands; control panel 4 refers to an operation interface integrating human-machine interaction functions, which can be implemented using a composite structure with physical buttons and an LCD screen, used to provide status display and command input functions; switch 7 can be set as one of the buttons of input module 6 or a mechanical switch with multiple gear selection, which can be implemented using a rotary or toggle switch structure, used to switch between different locking modes.

[0045] Specifically, when the vehicle is in the unlocked state, the user selects the target locking mode through the switch 7; the processor 3 activates the corresponding unlocking control logic according to the selected mode. For example, in the normal mode, after the user enters the preset password through the input module 6, the processor 3 verifies the password and controls the hub motor 2 to enter the unlocked state; in the shortcut mode, the user directly triggers the unlocking command through a specific key combination; the hub motor 2 maintains the braking state in the locked state, preventing the wheels from rotating.

[0046] Compared with existing technologies, traditional solutions rely entirely on a single verification method and cannot adjust the security level according to the usage scenario. This solution achieves flexible configuration through a mode switching function, allowing users to select the quick mode when fast locking is needed and to activate the regular mode when parking for a long time. At the same time, the integrated control panel 4 centrally processes status display and operation input, reducing the number of user operation steps.

[0047] Through the above technical solutions, this application can select different locking modes according to actual usage needs, optimize the operation process while ensuring security; the mode switching function enables the vehicle to adapt to different parking scenarios, and the integrated control interface reduces the probability of misoperation.

[0048] This application further proposes that the processor 3 is electrically connected to the battery module 9; the battery module 9 is a battery installed on the control panel 4 or a battery inside the vehicle body 1 used to drive the hub motor 2;

[0049] Among them, battery module 9 refers to the power supply component that provides power to the locking device. Specifically, it can be implemented by an independent storage battery installed on the control panel 4 or a storage battery inside the vehicle body 1 used to drive the hub motor 2. The independent storage battery is integrated with the control panel 4 to avoid additional wiring. The storage battery inside the vehicle body 1 directly utilizes the existing power supply to reduce redundant structure. The storage battery refers to the device that stores electrical energy. Specifically, it can be implemented by lithium battery, lead-acid battery or polymer battery to provide a stable power supply to the processor 3 and control panel 4.

[0050] Specifically, processor 3 and control panel 4 are independently powered by battery module 9, avoiding the failure of the locking function due to power failure of the main power supply of vehicle body 1; when battery module 9 uses the independent battery on control panel 4, the locking device is separated from the drive system of vehicle body 1, which is convenient for later installation or maintenance; when battery module 9 uses the battery of the drive hub motor 2 inside vehicle body 1, the locking device shares power with vehicle body 1, reducing the space occupied by the independent battery; the two power supply methods can be selected according to actual needs, for example, independent batteries are preferred in modification scenarios, while the battery inside vehicle body 1 is used in the original design.

[0051] This application further proposes that the input module adopts any one or more of physical buttons, numeric keypads or touchpads to input locking commands or passwords to the processor 3 so that the hub motor 2 enters the locking state or unlocking state.

[0052] Among them, physical buttons refer to physical buttons with mechanical structures, which can be implemented using metal contacts or silicone materials, and are triggered by pressing to transmit electrical signals; numeric keypads refer to input interfaces composed of multiple numeric symbols, which can be implemented using matrix circuits or membrane switches, and are used to input specific passwords by combining them; touchpads refer to planar devices that use capacitive or resistive touch operation, which can be implemented using a glass substrate with a sensing layer, and are used to generate command signals by sliding or clicking; the vehicle lock command is configured as a control signal to trigger the hub motor 2 to enter the locked state, and the password is configured as a character combination to verify user permissions;

[0053] Specifically, when a user needs to lock the unicycle, they can generate a locking command by pressing a physical button. This command is transmitted to the processor 3 and triggers the hub motor 2 to enter the locking state. When unlocking is required, the user can choose to enter a preset password on the physical button or numeric keypad, or perform a specific gesture operation on the touchpad. The processor 3 verifies that the input information matches the stored data and then outputs an unlock signal. The multi-mode selection of the input module allows the user to choose any of the following methods: physical button operation, password verification, or touch interaction, depending on the environmental conditions or operating habits.

[0054] Compared with existing technologies, traditional unicycles only support a single unlocking method, such as requiring a fixed password or physical key, which cannot be used quickly in emergency situations or flexibly switched in complex environments. This solution integrates multiple input modules, so that the unlocking operation is no longer limited to specific devices or fixed procedures, while retaining the security mechanism of password verification.

[0055] Please refer to Figure 4 This application further proposes that the sensor assembly 10 includes at least a gyroscope or a position sensor, which is installed at the center of the vehicle body 1 to detect the tilt angle of the vehicle body;

[0056] Among them, a gyroscope is a device used to measure the angular velocity or tilt angle of an object. Specifically, it can be implemented using a MEMS gyroscope or a fiber optic gyroscope. By detecting the change in the tilt angle of the vehicle body 1 relative to the horizontal plane, it can determine whether the vehicle is in an abnormal parking state. A position sensor is a device used to detect the displacement or motion state of an object. Specifically, it can be implemented using a Hall sensor or a photoelectric encoder.

[0057] Taking a gyroscope as an example, the gyroscope is placed on the vehicle body 1 and can accurately capture the attitude changes of the vehicle body 1. When the vehicle is tilted by an external force exceeding a preset threshold, the processor 3 triggers an alarm based on the gyroscope signal. Taking a position sensor as an example, the position sensor is installed on the vehicle body 1. When the vehicle is tilted by an external force exceeding a preset threshold, the position sensor generates a pulse signal and transmits it to the processor. The processor 3 triggers an alarm based on the pulse signal.

[0058] This application further proposes that the vehicle locking device also includes a warning light, which is installed on the outer side of the vehicle body 1. The warning light 8 is electrically connected to the processor 3. In the locked state, if the sensing data of the sensor component 10 is abnormal, the processor 3 controls the warning light 8 to light up and alarm. Or, in the locked state, if the number of times the user enters an incorrect password into the input module 6 exceeds a preset threshold, the processor 3 controls the warning light 8 to light up and alarm.

[0059] Specifically, the alarm can be triggered by flashing light or constant light; the number of incorrect password attempts exceeds the preset threshold when the password received by the input module 6 is entered incorrectly three times consecutively; the vehicle body tilts when the angle between the vehicle body 1 and the horizontal plane is detected by the sensor as exceeding the safe range, for example, exceeding 15 degrees, which is considered an abnormal state.

[0060] Please refer to Figure 4 This application further proposes that the vehicle locking device also includes an alarm sound module 11, which is disposed on the control panel 4 or the vehicle body 1. The alarm sound module 11 is electrically connected to the processor 3. In the locked state, if the sensing data of the sensor component 10 is abnormal or the number of incorrect password inputs by the input module 6 exceeds a preset threshold, the processor 3 controls the alarm sound module 11 to emit an alarm sound.

[0061] Among them, the alarm sound module 11 refers to an alarm device that can emit sound signals. It can be a buzzer, a horn or a speaker. The buzzer emits a high-frequency "beep beep" sound as the alarm sound, the horn emits a louder alarm sound, or the speaker plays a pre-recorded alarm voice as the alarm sound, so as to remind the user or relevant personnel that an abnormal situation has occurred.

[0062] In one application scenario, when the number of incorrect password inputs by the input module 6 exceeds a threshold, the processor 3 sends a drive signal to the alarm sound module 11 while controlling the warning light 8 to illuminate and alarm, triggering the alarm sound module 11 to emit a continuous buzzing sound; when the gyroscope or position sensor detects that the vehicle tilt angle exceeds a safety threshold, the processor 3 triggers the alarm sound module 11 to emit an intermittent alarm sound while controlling the warning light 8 to illuminate and alarm. On the basis of maintaining the original warning function, the auditory perception dimension is expanded, which can quickly attract the user's attention in scenarios such as continuous password errors and abnormal vehicle tilt, avoiding the risk of vehicle loss of control due to missed warning signals.

[0063] This application further proposes that the control panel 4 also includes a communication module, which is connected to the processor 3; or, the control panel 4 also includes a biometric identification module, which is connected to the processor 3, and the biometric identification module is a fingerprint identification module or a voiceprint identification module; or, the control panel 4 also includes a wireless receiving module, which is connected to the processor 3, and the wireless receiving module is an NFC module, a Bluetooth module or an infrared module.

[0064] The communication module refers to the hardware unit used to realize remote data transmission or command reception. It can be implemented using a Wi-Fi module, a 4G module, or an Ethernet module. Its function is to enable the locking device to receive remote control signals from external devices. The biometric recognition module refers to the component that verifies identity through human biometrics. It can be implemented using a fingerprint sensor or a microphone combined with a voiceprint recognition algorithm. Its function is to improve the security of the unlocking process through biometric verification. The wireless receiving module refers to the hardware unit used for short-range wireless communication. It can be implemented using a near-field communication chip, a Bluetooth chip, or an infrared sensor. Its function is to support short-range contactless unlocking operations.

[0065] Specifically, when the control panel 4 integrates a communication module, the user can send an unlock command to the communication module via a mobile terminal application. After verifying the legality of the command, the processor 3 controls the hub motor 2 to unlock. If a biometric identification module is used, after the user presses their fingerprint or enters their voiceprint on the control panel 4, the processor 3 compares the collected biometric features with the pre-stored data. Once the verification is successful, unlocking is triggered. For a wireless receiving module, the user can bring an NFC-enabled device close to the control panel 4. The wireless receiving module reads the device information and transmits it to the processor 3 for identity verification. Once the verification is successful, the hub motor 2 enters the unlocked state.

[0066] Compared with existing technologies, current unicycle locking devices typically only support password or physical key unlocking, and cannot achieve remote control, biometric verification or near-field communication unlocking, resulting in a single unlocking method that cannot adapt to different scenario requirements. This solution adds a variety of optional modules, enabling the locking device to flexibly select the unlocking method according to the usage environment. For example, in scenarios where fast passage is required, an NFC module can be used to achieve contactless unlocking, and fingerprint recognition can be enabled in scenarios requiring high security.

[0067] This application further proposes a vehicle locking device. The display screen 5 can be any one of an e-ink screen, an LCD screen, an OLED screen, or a VA screen. The display screen 5 is used to display the input information of the input module 6 and the current status of the hub motor 2.

[0068] Among them, electronic ink screen refers to a low-power screen based on electrophoretic display technology, which can use microcapsules to encapsulate charged particles to achieve image display. Its characteristics are high visibility in strong light environments and no need for backlight; LCD screen refers to liquid crystal display screen 5, which can use thin film transistors to drive the deflection of liquid crystal molecules to achieve display. Its characteristics are low cost and stable display color; OLED screen refers to organic light-emitting diode display screen 5, which can use organic material layers to emit light when current passes through to achieve display. Its characteristics are high contrast and fast response speed; VA screen refers to vertical alignment liquid crystal display screen 5, which can use the vertical alignment of liquid crystal molecules to achieve wide viewing angle display. Its characteristics are wide viewing angle and excellent black performance;

[0069] Specifically, when a user enters a password or operation command through input module 6, the input information can be displayed on the selected display screen 5 in real time. For example, in outdoor scenarios, an e-ink screen can clearly display the input characters, while in nighttime scenarios, an OLED screen can improve visibility by utilizing its self-illuminating properties. The locked or unlocked status of the hub motor 2 is dynamically updated on the screen in the form of text or icons. Different screen types can be adapted according to the usage environment or power consumption requirements. For example, in low-battery situations, the e-ink screen can be used first to reduce energy consumption.

[0070] This application further proposes a vehicle locking device including preset modes, which include a first vehicle locking mode and a second vehicle locking mode; in the first vehicle locking mode, the password input by the input module 6 triggers the processor 3 to output a control signal, causing the hub motor 2 to enter the unlocked state; in the second vehicle locking mode, the shortcut key of the input module 6 triggers the processor 3 to output a control signal, causing the hub motor 2 to enter the unlocked state.

[0071] Among them, the preset mode refers to different locking control logics pre-set in the processor 3, which are used to switch different unlocking trigger methods according to user needs; the password trigger refers to starting the unlocking process by verifying a specific character combination entered by the user, which is used to ensure the legitimacy of the operation in scenarios requiring high security; the shortcut key trigger refers to directly starting the unlocking process through a single operation of a physical button or touch area, which is used to simplify the user interaction steps in scenarios requiring fast operation.

[0072] Specifically, when the user needs to use the vehicle daily, they can switch to the first locking mode and verify their identity by entering a pre-set password. After receiving the correct password, the processor 3 drives the wheel hub motor 2 to unlock the vehicle. When the user needs to retrieve the vehicle quickly, they can switch to the second locking mode. By pressing a specific physical button on the control panel 4, the processor 3 immediately responds to the button signal and controls the wheel hub motor 2 to unlock the vehicle. The switching between the two modes is achieved through a switch 7, which can be set to a knob or a toggle mechanism, with each position corresponding to a different working mode.

[0073] Compared with existing technologies, traditional unicycle locks only support a single unlocking method, which cannot meet the needs of both security and operational efficiency. This solution, by setting up a dual-mode unlocking mechanism, retains the security advantage of password verification while increasing the convenience of fast operation, effectively solving the conflicting needs in different usage scenarios.

[0074] This application further proposes a unicycle, including a locking device electrically connected to a hub motor 2. The hub motor 2 is installed under the vehicle body 1 to drive the vehicle body 1 to move. The locking device includes a processor 3, a control panel 4, and a warning light 8. The processor 3 is installed inside the vehicle body 1 to output control signals to adjust the locking and unlocking states of the hub motor 2. The control panel 4 is installed on the outer surface of the vehicle body 1 and integrates a display screen 5, an input module 6, and a switch 7. The display screen 5, input module 6, and switch 7 are electrically connected to the processor 3. The warning light 8 is installed on the outer surface of the vehicle body 1 and is electrically connected to the processor 3. The switch 7 is set with several preset input positions. When the hub motor 2 is unlocked, the switch 7 and the processor 3 control the hub motor 2 to enter the locking state in a preset mode.

[0075] Among them, the hub motor 2 refers to the power device that drives the wheel to rotate by electricity, which can be implemented by a brushless DC motor. After being connected to the processor 3, it can switch between rotation and locking states according to the electrical signal. The switch 7 refers to a physical switch with multiple positions, which can be implemented by a rotary encoder, a toggle switch or a multi-level button switch. Different positions trigger the processor 3 to execute the corresponding locking mode. The preset mode refers to the pre-set locking logic, which can be implemented by password verification or shortcut key triggering method, and is used to switch the unlocking verification mechanism in different usage scenarios.

[0076] Specifically, when the unicycle is parked, the switch 7 is adjusted to the target gear, and the processor 3 activates the corresponding locking mode according to the gear signal. In the first locking mode, the user enters a password through the input module 6 to trigger the processor 3 for verification. After successful verification, the hub motor 2 is unlocked. In the second locking mode, the user directly triggers the processor 3 to send an unlock command through the shortcut button on the control panel 4, and the hub motor 2 is immediately unlocked. The warning light 8 displays the operation status in real time during the locking process. If the number of incorrect inputs exceeds the threshold or the unicycle body 1 tilts, the warning light 8 illuminates and triggers the alarm sound module 11 to sound an alarm.

[0077] The above description is only a preferred embodiment of the present utility model and does not limit the patent scope of the present utility model. All equivalent structural transformations made under the inventive concept of the present utility model using the contents of the present utility model specification and drawings, or direct / indirect applications in other related technical fields, are included within the patent protection scope of the present utility model.
