[0036] The specific embodiments of the application have been shown and described in the above drawings, which will be described in more detail hereinafter. These drawings and written descriptions are not intended to limit the scope of the concept of the application in any way, but to illustrate the concept of the application to those skilled in the art by referring to specific embodiments. DETAILED DESCRIPTION
[0037] In order to better understand the scheme of the application for those skilled in the art, the technical solutions in the embodiments of the application will be described clearly and completely below in conjunction with the drawings in the embodiments of the application. Obviously, the described embodiments are only a part of the embodiments of the application, not all the embodiments. Based on the embodiments in the application, all other embodiments obtained by those skilled in the art without creative labor should be within the scope of protection of the application.
[0038] It should be noted that the terms "first", "second", and the like in the description and in the claims of the present application and the above-described accompanying drawings are used to distinguish similar objects, and do not necessarily indicate a specific order or sequence. It should be understood that the data thus used can be interchanged under appropriate circumstances, so that the embodiments of the present application described herein can be implemented in an order other than that illustrated or described herein. In addition, the terms "include" and "have" and any variations thereof are intended to cover non-exclusive inclusion.
[0039] As described in the background, electronic locks are usually controlled and driven by vehicle controllers outside the lock body; the specific control and driving process can be: when the user issues an unlocking or locking instruction through a key, a remote control or other control device, the vehicle controller will generate a corresponding driving signal according to the instruction. These signals are usually based on a specific coding protocol and electrical signal format, such as a Pulse Width Modulation (PWM) signal, which controls the speed and direction of rotation of the motor by changing the duty cycle of the pulse.
[0040] Since the signal power output by the vehicle controller is usually small and cannot directly drive the motor inside the electronic lock, the generated driving signal can be transmitted through external leads to a motor driver also located outside the electronic lock. The motor driver amplifies the received signal to enhance its driving capability to provide sufficient current and voltage to drive the motor to operate. In turn, the amplified driving signal is transmitted to the inside of the electronic lock through external leads, so that the driving signal acts on the motor inside the lock body, realizing the rotation of the motor in the predetermined direction. For example, in the unlocking state, the motor rotates forward, driving the lock cylinder to rotate through the transmission device, so that the lock tongue is in the retracted state, realizing the unlocking action; in the locking state, the motor reverses, driving the lock cylinder to rotate in the opposite direction, so that the lock tongue is in the extended state, completing the locking action.
[0041] After the electronic lock completes the unlocking or locking action, the position sensor pre-installed in the lock body can detect the position state of the lock tongue and convert the detected lock tongue state signal into an electrical signal, which is fed back to the vehicle controller through external leads. These feedback signals can be simple on-off signals (high or low), or more complex digital signals, depending on the type of sensor and the design of the controller.
[0042] After receiving the feedback signal representing the state of the lock tongue, the vehicle controller will determine whether the lock tongue has reached the correct position, i.e. whether it has been successfully unlocked or locked, according to the pre-set logic. If the lock tongue state does not match the expectation, the vehicle controller may take appropriate measures, such as sounding an alarm or displaying fault information on the instrument panel, to prompt the user that the lock may have a problem.
[0043] It should be understood that, in order to achieve the above motor driving and bolt position detection, the electronic lock needs to be connected with the vehicle controller through multiple external leads. However, such a design of multiple external leads has the following problems in practical application:
[0044] 1. Poor anti-interference ability
[0045] During the operation of the electric bicycle, there are various electromagnetic interference sources around, and the external leads between the electronic lock and the vehicle controller are usually thin and long. When they are in the above electromagnetic interference environment, they are easy to receive electromagnetic interference signals, which may cause distortion of the driving signal of the motor, so that the motor driver receives incorrect signals, thereby affecting the normal rotation of the motor, such as unstable motor speed, incorrect rotation direction, or failure to start normally. At the same time, the interference may also distort the bolt state detection signal, causing the external controller to be unable to accurately determine the actual position of the bolt, and further causing false alarms, incorrect display of the lock status, etc.
[0046] 2. High complexity of wire harness
[0047] Since the electronic lock needs an external motor driver to drive the motor to rotate, and an external vehicle controller to detect the bolt state, the electronic lock needs to draw out wire harnesses connected with the motor driver and the external controller, respectively. More wire harnesses need to be arranged reasonably at the vehicle frame, handle, etc. during the wiring in the vehicle, to avoid interference with other components, while also ensuring the safety and reliability of the wire harnesses. This not only increases the difficulty of wiring, but also may cause mutual interference between the wire harnesses, affecting the signal transmission quality. In addition, the use of multiple wire harnesses increases the material cost, including the cost of wires, connectors, etc. Moreover, the installation and wiring of the wire harnesses require more labor cost, and more time and effort are needed for the laying and connection of the wire harnesses during the production process, thereby increasing the production cost of the vehicle.
[0048] 3. Low integration
[0049] In the existing related design, the vehicle controller, the motor driver, and the electronic lock are separated from each other. Such a separated design makes the structure of the entire system loose, and the components need to be connected and communicated through wire harnesses. Once a component or the connection between them has a problem, it may cause the entire electronic lock system to malfunction, challenging the reliability and stability of the vehicle. In addition, the separated design also increases the difficulty and workload of system integration during the design and production of the vehicle, affecting the production efficiency and product quality.
[0050] To solve the above technical problems, the electronic lock circuit, the electronic lock and the vehicle are provided in the embodiments of the present application. The driving module for driving the motor in the lock body is integrated in the electronic lock circuit, and the electronic lock circuit is arranged in the electronic lock, so that the integration of the vehicle is improved. The control module in the electronic lock circuit and the vehicle controller outside the electronic lock are connected through single bus communication, so that the number of wire harnesses connected between the electronic lock and the outside is reduced, the risk of electromagnetic interference is reduced, the wire harness structure is simplified, and the integration and reliability of the vehicle system are improved and the cost is reduced.
[0051] The technical solutions of the present application and how the technical solutions solve the above technical problems will be described in detail below with specific embodiments. The following specific embodiments can be combined with each other, and the same or similar concepts or processes can not be described in detail in some embodiments. The embodiments of the present application will be described below with reference to the drawings.
[0052] In order to better explain the electronic lock circuit provided by the present embodiment, the vehicle in which the electronic lock circuit is arranged will be described in detail first.
[0053] The vehicle provided by the embodiments of the present application can include but is not limited to electric two-wheeled vehicles, electric three-wheeled vehicles or electric four-wheeled vehicles, etc. In the embodiments of the present application, the vehicle is taken as an example of an electric two-wheeled vehicle, which can include electric motorcycles and electric bicycles, etc. The type of electric two-wheeled vehicle is not limited further.
[0054] Figure 1 A structural schematic diagram of a vehicle provided by the embodiments of the present application is shown in FIG. 1. Referring to FIG. 1, the vehicle 1 includes a vehicle controller 10 and an electronic lock 20 in communication connection with the vehicle controller 10. Figure 1
[0055] In the present application, the vehicle controller 10 can be understood as the core control unit of the whole vehicle, which is used to coordinate and control various systems of the vehicle. According to different vehicle models and design requirements, the position of the vehicle controller 10 in the vehicle 1 can be different, for example, it can be installed at the front of the vehicle 1, under the pedal or under the seat pan, etc. to adapt to the overall layout and functional requirements of the vehicle 1.
[0056] Some vehicles 1 can also install the vehicle controller 10 at other positions such as the side or tail of the frame in order to achieve better heat dissipation or specific structural layout. The position of the vehicle controller 10 in the vehicle 1 is not limited in the embodiments of the present application.
[0057] It should also be understood that the electronic lock 20 is a safety device arranged in the vehicle 1, which aims to improve the anti-theft performance and user convenience of the vehicle 1 through electronic control technology.
[0058] Optionally, the electronic lock 20 realizes the anti-theft of the vehicle 1 by controlling the unlocking and locking operation of the key components of the vehicle. According to the different setting positions of the key components in the vehicle 1, the types of the electronic lock are also different, including but not limited to the faucet lock, the saddle lock, the tire lock, the frame lock and the battery lock, etc.
[0059] In the present application, the vehicle controller 10 generates the control signal for the electronic lock 20 to control the electronic lock 20 to perform the unlocking action or the locking action by receiving the unlocking or locking instruction issued by the user. After the electronic lock 20 performs the action, the execution feedback signal issued by the electronic lock 20 is received to determine the corresponding execution result, i.e. the unlocking execution success or the locking execution success, and then the corresponding control instruction can be given according to the execution result.
[0060] In an optional embodiment, the vehicle controller 10 and the electronic lock 20 can communicate through a single bus. Optionally, the vehicle controller 10 can transmit the control signal to the electronic lock 20 through the single bus, and the electronic lock 20 will transmit the execution feedback signal back to the vehicle controller 10 through the same bus after performing the corresponding operation. In this way, the communication through the single bus can simplify the number of wire harnesses connected between the electronic lock and the vehicle controller in the vehicle, and improve the integration and reliability of the whole vehicle system.
[0061] Figure 2 Another structure schematic diagram of the vehicle provided by the embodiment of the present application is provided. Referring to Figure 2 The vehicle 1 provided by the embodiment of the present application further includes an alarm 30, which is connected with the vehicle controller 10.
[0062] Optionally, when the execution feedback signal transmitted by the electronic lock 20 to the vehicle controller 10 indicates that the electronic lock 20 has not successfully unlocked or locked, the vehicle controller 10 will generate the corresponding alarm signal and transmit it to the alarm 30 to prompt the user that the lock may have a problem. At the same time, measures such as displaying the fault information on the instrument panel or the user terminal and retransmitting the driving signal can also be taken to further remind the user and try to solve the problem. In this way, not only the safety of the whole vehicle system can be improved, but also the real-time control of the vehicle state by the user can be enhanced.
[0063] On the basis of the above-mentioned embodiments, the electronic lock in the vehicle provided by the embodiment of the present application is further described in detail.
[0064] Figure 3 A structure schematic diagram of an electronic lock provided by the embodiment of the present application is provided. Referring to Figure 3 The electronic lock 20 includes: an execution component 21 for performing the locking and unlocking operation, a motor 22 for driving the execution component, and an electronic lock circuit 23 for controlling the operation of the motor.
[0065] In this application, the electronic lock circuit 23 serves as the core control unit of the electronic lock 20, which controls the operation of the motor 22 inside the lock body, thereby enabling the drive actuator 21 to perform locking and unlocking operations.
[0066] Optionally, the electronic lock circuit 23 receives the control signal output from the vehicle controller 10 and amplifies it to enhance its driving capability, so as to provide sufficient current and voltage to drive the motor 22 to operate; then the amplified driving signal is transmitted to the motor 22 to realize the action of the drive actuator 21.
[0067] In practical applications, the actuator 21 may include, but is not limited to, structures such as a locking tongue and a locking latch. When the motor 22 receives a locking command, the motor 22 rotates in a first preset direction, causing the actuator 21 to be in the extended position, thereby preventing the movement of certain components of the vehicle 1 (such as the steering wheel, saddle, etc.), thus completing the locking operation and playing a role in theft prevention; when an unlocking command is received, the motor 22 rotates in the opposite direction or at different speeds, and the actuator 21 will change to the retracted position under the drive of the motor 22, so that the relevant components of the vehicle 1 can operate normally.
[0068] For example, in the handlebar lock of an electric bicycle, when the motor 22 drives the lock tongue to be in the extended state, the handlebars of the electric bicycle cannot be turned, causing the electric bicycle to be in a locked state; when the motor 22 drives the lock tongue to be in the retracted state, the handlebars can move normally, realizing the unlocking of the electric bicycle.
[0069] Based on the above, the electronic lock circuit 23 may also have other functions, such as monitoring the status of the motor 22 and the actuator 21, and taking corresponding protective measures when an abnormality is detected (such as motor overload, actuator jamming, failure to execute, etc.), such as cutting off the motor power supply to prevent damage; or sending alarm information to the instrument panel or user terminal of the vehicle 1.
[0070] Based on the above embodiments, the electronic lock circuit in the electronic lock provided in the embodiments of this application will be further described in detail below.
[0071] Figure 4 This is a schematic diagram of an electronic lock circuit provided in an embodiment of this application. See also... Figure 4 The electronic lock circuit 23 includes a control module 231 and a drive module 232. The communication terminal of the control module 231 is connected to the vehicle controller 10 via a single bus, and the motor control terminal of the control module 231 is connected to the control terminal of the drive module 232. The drive output terminal of the drive module 232 is connected to the motor 22.
[0072] In the present application, the control module 231 can be implemented by any controller with data analysis and processing functions, such as a microcontroller and a single-chip microcomputer.
[0073] The driving module 232 can be implemented by any device or circuit capable of amplifying the low-power control signal output by the control module 231 to provide sufficient current and voltage to drive the motor 22 to operate normally, such as a power amplifier and a motor driving chip.
[0074] Optionally, the communication end of the control module 231 is connected to the vehicle controller 10 through a single bus. The single bus has the characteristics of simple hardware and the ability to mount multiple devices. Based on these advantages, the vehicle controller 10 can conveniently send control signals, such as a locking signal or an unlocking signal, to the control module 231 through the single bus. At the same time, the control module 231 can also feed back the execution result of the electronic lock 20, the lock state and other information to the vehicle controller 10 through the single bus.
[0075] Optionally, the motor control end of the control module 231 is connected to the control end of the driving module 232, so that the driving module 232 receives the low-power control signal output by the control module 231, amplifies it using devices such as a power amplifier and a motor driving chip, and converts it into a driving signal that can provide sufficient current and voltage for the motor 22.
[0076] On this basis, the driving output end of the driving module 232 is connected to the motor 22, so that the driving signal processed and amplified will be transmitted to the motor 22, causing the motor 22 to rotate according to the control signal of the control module 231, thereby driving the execution component 21 to complete the locking or unlocking operation.
[0077] The electronic lock circuit provided by the embodiment of the present application integrates the driving module for driving the motor in the lock body in the electronic lock circuit, sets the electronic lock circuit in the electronic lock, and uses a single bus to communicate the control module in the electronic lock circuit and the vehicle controller outside the electronic lock, thereby reducing the number of wire harnesses connected to the electronic lock, reducing the risk of electromagnetic interference, simplifying the wire harness structure, and achieving the effects of significantly improving the integration and reliability of the vehicle system and reducing the cost.
[0078] The specific structures of the functional modules in the electronic lock circuit 23 will be described exemplarily below, but not as a limitation of the present application.
[0079] Figure 5 Another structure diagram of an electronic lock circuit provided by the embodiment of the present application is shown in FIG. 3. Referring to FIG. 3, the electronic lock circuit 23 comprises a control module 231, a driving module 232 and a motor 22. Figure 5On the basis of the above-mentioned embodiments, the control module 231 can optionally comprise a single-chip microcomputer 2310. Based on the small size, light weight, high integration and modularization of the single-chip microcomputer 2310, the circuit size and weight can be significantly reduced, the system complexity and cost can be reduced, and the upgrading and maintenance can be facilitated.
[0080] Referring to Figure 5 On the basis of the above-mentioned embodiments, the electronic lock circuit 23 further comprises a position sensor 233 connected to the executing component 21 for detecting the position of the executing component 21, and the position sensor 233 is further connected to the position feedback end of the control module 231.
[0081] In the present application, the position sensor 233 can be interpreted as a device for detecting the position information of the executing component 21 in the electronic lock 20, which can convert the detected position information into an electrical signal and feed it back to the control module 231, so that the control module 231 can know the execution result of the electronic lock 20 in real time.
[0082] Optionally, the position sensor 233 is connected to the executing component 21 on the one hand, and realizes real-time detection of the position information of the executing component 21 through a preset sensing principle, such as detecting whether the executing component 21 is in a completely locked or unlocked state, and the specific position in the action process, etc. On the other hand, the position sensor 233 is connected to the position feedback end of the control module 231, and converts the detected executing component position information into an electrical signal and transmits it to the control module 231. In this way, the control module 231 can accurately understand the actual state of the executing component 21 according to the received position feedback signal, so as to realize precise control of the electronic lock 20.
[0083] On the basis of the above-mentioned embodiments, in an optional solution, the control module 231 obtains the position information of the executing component 21 after receiving the low-power control signal transmitted by the vehicle controller 10. If the position information matches the type of the control signal, the control module 231 transmits the control signal to the driving module 232 for amplification processing; otherwise, if the position information does not match the type of the control signal, the control module 231 generates an alarm signal and transmits the alarm signal to the vehicle controller 10, so that the vehicle controller 10 sends the alarm signal to the alarm 30 to prompt the user that the lock may have a problem.
[0084] For example, continuing with the example of the electric bicycle's lock, when the control module 231 receives the unlock signal transmitted by the vehicle controller 10, if the position information indicates that the lock tongue is in the extended position, the unlock signal is transmitted to the drive module 232 and then to the motor 22, thereby achieving the unlocking of the electric bicycle; otherwise, if the position information indicates that the lock tongue is in the retracted position, an alarm signal is generated and transmitted to the vehicle controller 10 for alarm processing.
[0085] For example, when the control module 231 receives the lock signal transmitted by the vehicle controller 10, if the position information indicates that the lock tongue is in the retracted position, the lock signal is transmitted to the drive module 232 and then to the motor 22, thereby achieving the locking of the electric bicycle; otherwise, if the position information indicates that the lock tongue is in the extended position, an alarm signal is generated and transmitted to the vehicle controller 10 for alarm processing. In this way, the safety and reliable operation of the electronic lock system can be further ensured.
[0086] Figure 6 Another schematic diagram of the vehicle structure is provided for the embodiments of the present application. Referring to Figure 6 On the basis of the above-mentioned embodiments, the electronic lock circuit 23 optionally further comprises a power input end; the power input end 233 is connected to the power output end of the vehicle controller 10.
[0087] Optionally, the electronic lock circuit 23 is provided with a power input end during the design process, which is used to provide power for the electronic lock 20. Since the vehicle controller 10 also has the function of managing and distributing electric energy, the power output end of the vehicle controller 10 is connected to the power input end of the electronic lock circuit 23 in the present application.
[0088] Through the above connection, the vehicle controller 10 can stably transmit the electric energy (usually from the battery system of the vehicle 1) obtained by itself to the electronic lock circuit 23. In this way, each component in the electronic lock circuit 23, such as the control module 231, the drive module 232, and the position sensor 233, can obtain continuous and stable power supply, thereby ensuring that the electronic lock 20 can operate stably, realizing the control of the motor 22 to drive the execution component 21 to complete the locking and unlocking operations, and protecting the safety function of the vehicle 1.
[0089] Referring to Figure 6 On the basis of the above-mentioned embodiments, the electronic lock circuit 23 provided by the present application further comprises: a power conversion module 234; the input end of the power conversion module 234 is connected to the power input end 233, the first output end of the power conversion module 234 is connected to the power input end of the drive module 232, and the second output end of the power conversion module 234 is connected to the power input end of the control module 231.
[0090] Optionally, the input end of the power conversion module 234 is connected with the power input end of the electronic lock circuit 23, indicating that the power conversion module 234 can obtain the power provided by the vehicle 1. However, due to the voltage, current characteristics and other parameters of the original power signal provided by the vehicle 1 in actual application, it is usually difficult to directly match the working requirements of the driving module 232 and the control module 231, so that the power conversion module 234 needs to convert the provided power to obtain the power that meets the requirements of each module in the circuit.
[0091] Optionally, the first output end of the power conversion module 234 is connected with the power input end of the driving module 232, which can convert the input power into a specific voltage and current form suitable for the working of the driving module 232, ensuring that the driving module 232 has stable and suitable power supply, so as to efficiently drive the motor 22 to operate. At the same time, the second output end of the power conversion module 234 is connected with the power input end of the control module 231, realizing the provision of power meeting the working requirements of the control module 231 for the control module 231, and guaranteeing the accurate execution of the functions such as signal processing and instruction transmission of the control module 231.
[0092] Through the addition of the power conversion module 234, the modules of the electronic lock circuit 23 can work cooperatively in the adaptive power environment, improving the stability and reliability of the whole vehicle system.
[0093] Referring to Figure 6 On the basis of the above-mentioned embodiments, the power conversion module 234 includes a low dropout regulator 2340; the power input end 233 is connected with the first end of the low dropout regulator 2340, the second end of the low dropout regulator 2340 is taken as the second output end of the power conversion module 234; and the power input end of the driving module 232 is further connected with the second output end of the power conversion module 234.
[0094] In the present application, the power conversion module 234 includes a low dropout regulator 2340 (Low Dropout Regulator Circuit, LDO) for providing stable voltage output, that is, maintaining constant output voltage even in the case of input voltage fluctuation or load change. It is usually composed of a power transistor (such as MOSFET or bipolar transistor), error amplifier and voltage reference. The error amplifier compares the output voltage with the reference voltage and adjusts the conduction state of the power transistor to maintain stable output.
[0095] Optionally, the vehicle power supply is connected to the power input end of the electronic lock circuit 23, and is connected to the first end of the low dropout linear regulator 2340 to provide the original input power supply. Based on the characteristics of the low dropout linear regulator 2340, the input power supply in the vehicle electronic circuit can be processed to achieve stable voltage output.
[0096] Optionally, the second end of the low dropout linear regulator 2340 is used as the second output end of the power conversion module 234 to provide stable power supply for the control module 231, so that the control module 231 can stably process signal analysis and other tasks. At the same time, the power input end of the driving module 232 is also connected to the second output end of the power conversion module 234, and the driving module 232 and the control module 231 share the same stable power supply processed by the low dropout linear regulator 2340. In this way, it can be ensured that the driving module 232 can obtain stable and reliable power when driving the motor 22 to perform the unlocking and locking actions of the electronic lock 20, thereby ensuring that the entire electronic lock circuit 23 can stably and efficiently operate.
[0097] For example, the driving module 232 of the electronic handlebar lock circuit in the electric bicycle needs an external input voltage of 12V to provide sufficient power to drive the motor 22 to complete the unlocking and locking actions of the handlebar lock. However, the control module 231 (single-chip microcomputer 2310) cannot directly use such a high voltage of 12V, and its voltage requirement is relatively low, generally 3.3V or 5V. Based on the above requirements, a low dropout linear regulator 2340 can be used to process the 12V voltage input into the electronic handlebar lock circuit to provide power supply meeting the requirements of the driving module 232 and the control module 231 (single-chip microcomputer 2310). For example, when the external input voltage of 12V enters the low dropout linear regulator 2340, the low dropout linear regulator 2340 will adjust and stabilize the input voltage through the internal circuit mechanism, and finally output stable 3.3V or 5V voltage to the control module 231 (single-chip microcomputer 2310). At the same time, stable 12V voltage is also transmitted to the driving module 232. In this way, it is ensured that the control module 231 and the driving module 232 receive stable voltages that have been stabilized, thereby improving the reliability and performance of the entire vehicle system.
