[0034] The following will be combined with the drawings in the embodiments of the present invention to clearly and completely describe the technical solutions in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, not all of the embodiments. Based on the embodiments of the present invention, all other embodiments obtained by ordinary technicians in this field without creative work are within the scope of protection of the present invention.

[0035] The following is combined with Figure 1-Figure 3 The specific implementation modes of the present invention are described in further detail.

[0036] Depend on Figure 1-Figure 3 The present invention includes a data acquisition unit, a data analysis unit, a data storage unit, a vehicle life cycle management unit, a brake adjustment unit, and a driving state learning unit, in order to achieve the purpose of timely detection and reminder of the vehicle state, wherein:

[0037] The vehicle life cycle management unit includes a brake management unit for detecting and evaluating the braking force of the vehicle, a battery management unit for detecting and evaluating the battery life, and a motor management unit for detecting and evaluating the motor life;

[0038] The data acquisition unit is used to collect the data required by the brake management unit, the battery management unit and the motor management unit, and to collect the vehicle throttle size data;

[0039] The data analysis unit is used to perform data noise reduction and data analysis on the data collected by the data collection unit;

[0040] The data storage unit is used to store the data collected and analyzed by the data collection unit and the data analysis unit;

[0041] The brake adjustment unit is used to detect the rotation angle of the brake handle and adjust the brake tightness;

[0042] The driving state learning unit is used to detect and record the extension and contraction state of the vehicle shock absorber, and optimize the data collection frequency of the data collection unit according to the vehicle's mileage.

[0043] Furthermore, in order to detect the battery status, motor status and braking force of the vehicle, the data acquisition unit includes:

[0044] A first torque sensor for detecting a braking torque, wherein the first torque sensor is installed between a brake disc and a wheel shaft of the vehicle;

[0045] a first tension sensor for detecting the tension exerted on the brake line;

[0046] An energy meter and a voltmeter, wherein the energy meter is disposed between the vehicle charging port and the battery and is used to detect and record the total amount of electrical energy input to the battery, and the voltmeter is used to detect the total output voltage of the battery;

[0047] A second torque sensor for detecting the motor output torque, wherein the second torque sensor is arranged between the motor output shaft and the wheel shaft;

[0048] The voltage sensor is used to detect the voltage signal output by the vehicle throttle.

[0049] Furthermore, in order to achieve the purpose of accurately measuring the braking state, a preset standard braking torque is stored in the braking management unit, and the braking management unit is electrically connected to the first tension sensor, so that the actual braking torque can be compared and evaluated with the preset standard braking torque;

[0050] It should be noted that during normal driving of the vehicle, the brakes will wear out and the maximum braking torque will decrease as the vehicle is used, which poses a hidden danger;

[0051] When the brake management unit is operating, the tension on the brake line can be obtained through the first tension sensor, and the real-time braking torque can be obtained through the first torque sensor of the data acquisition unit. By comparing the two with the corresponding relationship between the standard brake tension and braking torque stored in the brake management unit, the wear of the brake disc can be obtained.

[0052] Furthermore, in order to accurately detect the vehicle power, the battery management unit stores corresponding data of standard power input and battery power percentage change, and the voltmeter detects the battery output voltage to detect the battery remaining power percentage. By comparing the standard battery power percentage change data corresponding to the power input detected by the energy meter with the battery power percentage change data actually detected by the voltmeter, the battery capacity depreciation rate can be evaluated. The energy meter and the voltmeter are both existing technologies and will not be described in detail here.

[0053] When the battery management unit is operating, the energy meter can accurately calculate the total amount of electricity charged into the battery during the charging process, and the built-in data can obtain the accurate percentage of increase in the remaining battery power. This value is compared with the actual increase in the battery. If the actual increase is greater than the ideal value, it shows that the total capacity of the battery has decayed. At the same time, the data is fed back to the data analysis unit for further analysis.

[0054] Furthermore, in order to detect the motor state, the motor management unit stores corresponding data of the standard throttle output voltage and the motor output torque. The motor management unit is electrically connected to the voltage sensor, and can compare and evaluate the motor output torque corresponding to the same throttle output voltage with the standard output torque.

[0055] When the motor management unit is operating, the throttle size can be detected through the voltage sensor, and the standard motor output torque under the throttle size can be obtained from the built-in data, which is compared with the real data obtained by the second torque sensor in the data acquisition unit to obtain the motor working status, and the information is fed back to the data analysis unit for further analysis.

[0056] Furthermore, in order to automatically tighten the brake line, the brake adjustment unit includes an angle sensor and a brake fastening mechanism. The angle sensor is a prior art and will not be described in detail herein. The angle sensor can detect the rotation angle of the brake handle. When the angle sensor detects that the brake angle is rotated too much and exceeds a preset value, the brake line is tightened through the brake fastening mechanism. The brake fastening mechanism is used to connect the brake handle and the brake.

[0057] It should be noted that due to the shortcomings of existing electric bicycle brake cables, the brake cables may be stretched after long-term use, or the cooperation with the brakes may become loose, thereby making it impossible for the vehicle's brakes to obtain the maximum braking torque;

[0058] When the brake adjustment unit is operating, the rotation angle of the brake can be detected by the angle sensor. If it is detected that the rotation angle of the brake handle is too large, that is, the brake is "too loose", the brake tightening mechanism can be fed back to tighten the brake line, so that the brake can achieve the desired effect.

[0059] Furthermore, in order to detect and record vehicle driving data, the driving state learning unit includes:

[0060] Laser rangefinder, which can detect the relative displacement between the vehicle body and the shock absorber bracket;

[0061] A deep learning module capable of recording the relative displacement between the vehicle body and the shock absorber bracket and learning and recording abnormal data;

[0062] When in use, the data changes detected by the laser rangefinder can be used to obtain the approximate road conditions that the vehicle often drives on. For example, when the vehicle often drives on flat roads in the city, the data changes infrequently. If the vehicle often drives on bumpy roads, the data changes frequently and the change range is large. The deep learning module can then record and analyze the data, and when the staff reads the internal data of the deep learning module, it can assist the staff in adjusting the hardness of the vehicle suspension.

[0063] In addition, the deep learning module can read the internal data of the data analysis unit and the internal data of the data storage unit. When the data analysis unit obtains abnormal data from the brake management unit, battery management unit or motor management unit, it will increase the data collection frequency of the data collection unit to accurately record the vehicle information.

[0064] Furthermore, in order to reduce the frequency of brake maintenance by riders, the brake fastening mechanism includes a brake line 1, a first connecting block 2 and a second connecting block 3 are respectively provided at the front and rear ends of the brake line 1, the first connecting block 2 is fixedly connected to the brake line 1, a brake pad 4 is slidably sleeved on the outer side of the brake line 1, a first fixing ring 5 is fixedly connected to the rear side of the brake pad 4, a threaded rod 6 is rotatably connected to the rear side of the brake line 1 through a rotating connector, the middle part of the threaded rod 6 is threadedly connected to the second connecting block 3, the rear side of the threaded rod 6 is rotatably connected to a power shell 7, and the front side of the power shell 7 is fixedly connected Two connecting rods 8 are connected, and a micro motor 9 is fixedly connected inside the power shell 7. The micro motor 9 is a micro servo motor, which is a prior art, such as a Beili micro motor, which will not be described in detail here. The output shaft of the micro motor 9 is fixedly connected to the threaded rod 6. A spring 10 is provided between the first fixing ring 5 and the second connecting block 3. The micro motor 9 is equipped with a controller that can receive the signal of the angle sensor. Each time the signal is received, the output shaft of the micro motor 9 rotates one circle. Furthermore, the first tension sensor is arranged on the brake line 1 near the first fixing ring 5 to facilitate maintenance and data transmission.

[0065] When in use, the first connecting block 2 can be connected to the brake handle, the second connecting block 3 can be connected to the brake, and the two connecting rods 8 can be clamped with the brake so that the power shell 7 will not rotate with the brake. When the brake action is performed, the brake handle will pull the first connecting block 2 to move, and then pull the second connecting block 3 to move under the action of the brake line 1, thereby driving the brake to perform the braking action. When the micro motor 9 is started, it will drive the threaded rod 6 to rotate. Since the threaded rod 6 is threadedly connected to the second connecting block 3, when the threaded rod 6 rotates, it will push the second connecting block 3 away from the power shell 7. At this time, the total distance between the brake line 1 and the threaded rod 6 between the first connecting block 2 and the second connecting block 3 is reduced, so that the brake handle can transmit a certain pulling force to the brake through the brake line 1 and the threaded rod 6;

[0066] Furthermore, the deep learning module is provided with an external interface, so that the staff can read the data of the deep learning module through the external interface, and then summarize the abnormal data of the vehicle through the deep learning module, so as to facilitate the staff to detect and debug the vehicle.

[0067] The present invention has a novel structure, ingenious conception, and simple and convenient operation. Through this design, the purpose of being able to monitor the status of the vehicle's brakes, batteries, and motors is effectively achieved, so that the staff can timely detect and debug various components of the vehicle, thereby increasing the service life of the vehicle, and realizing the function of automatically debugging the tightness of the vehicle's brakes, thereby reducing the frequency of brake inspections by riders and increasing the safety of braking.

[0068] Although the present invention has been described in detail with reference to the aforementioned embodiments, it is still possible for those skilled in the art to modify the technical solutions described in the aforementioned embodiments, or to make equivalent substitutions for some of the technical features therein. Any modifications, equivalent substitutions, improvements, etc. made within the spirit and principles of the present invention should be included in the protection scope of the present invention.
