[0002] With the rapid development of the social economy, the traffic pressure and parking pressure in the urban CBD have increased sharply. Convenient short-term rental lightweight means of transportation such as shared scooters, which have no traffic jam risk and parking pressure, have emerged as the times require. Currently, the shared scooters mainly adopt the power supply method of a main battery plus a secondary battery. The main battery supplies power to the entire system, and the secondary battery only provides emergency power for the communication part. When the main battery runs out of power, the system will send an emergency signal, and the emergency system is powered by the secondary battery. Since the capacity of the secondary battery is generally small, the power will be exhausted in a short time, resulting in the vehicle being permanently disconnected. Moreover, the secondary battery is a lithium-ion battery, and after the power is exhausted, it will cause damage to the internal structure of the battery, and there is a high probability of safety hazards such as fire and explosion when it is used again. Summary of the Invention

[0019] The present invention will be described in more detail below with reference to the drawings and embodiments.

[0020] The present invention discloses a shared scooter out-of-contact prevention control system. As shown in Figure 1 and Figure 2 , it includes a solar panel 1, a human-machine interaction unit 2, a secondary battery 3, a controller 4 and a main battery 5. The solar panel 1, the secondary battery 3, the controller 4 and the main battery 5 are respectively connected to the human-machine interaction unit 2, where:

[0021] The solar panel 1 is used to convert solar energy into electric energy and charge the secondary battery 3 through the human-machine interaction unit 2;

[0022] The human-machine interaction unit 2 is used to repeatedly send emergency signals to the server at a preset time interval.

[0023] In the above system, the human-computer interaction unit 2 includes an emergency system module 6 and a solar charging management module 7. In practical applications, the solar charging management module 7 receives the electric energy output by the solar panel 1 and charges the secondary battery 3, and the emergency system module 6 obtains electric energy from the secondary battery 3 and repeatedly sends emergency signals to the server at a preset time period. Compared with the prior art, the present invention adds a solar charging panel and a solar charging management module, and connects the solar charging system to the original power supply system. Under normal sunlight, it can provide continuous power supplement for the whole system. When the main battery of the shared scooter runs out of power, the electric energy converted from normal sunlight can maintain the power of the secondary battery in a safe state, so that the emergency system repeatedly sends emergency signals to the server at regular intervals. Because the energy is renewable, the emergency system will work for a long time, thus avoiding the situation of permanent loss of contact of the shared scooter. At the same time, it also ensures that the lithium-ion battery will not enter an over-discharged state, preventing situations such as damage to the internal structure of the battery caused by power exhaustion, and greatly reducing the safety hazards of the lithium battery.

[0024] Regarding the specific circuit structure of the solar charging part, in this embodiment, the output end of the solar panel 1 is connected to the solar charging management module 7 through a DC / DC circuit 8 and a diode 9 connected in series in sequence.

[0025] Further, the control end of the DC / DC circuit 8, the control end of the solar charging management module 7, and the control end of the emergency system module 6 are respectively connected to the controller 4.

[0026] In the above circuit, please refer to Figure 2 , which specifically includes two power supply circuits and a secondary battery emergency circuit. The two power supply circuits are the main battery power supply circuit and the solar power supply circuit respectively. The main battery power supply circuit passes through a fuse and is converted into the working power required by the system after being transformed by a DC / DC module. Similarly, the solar power supply circuit also passes through a fuse and is converted into the working power required by the system after being transformed by a DC / DC module. The solar power supply circuit and the main battery power supply circuit are isolated by a diode, and then through the regulation of the MCU, the solar power is preferentially used to meet the power supply of the control system. At the same time, the MCU is also used to control the charging management module to charge the secondary battery reasonably to keep it in a safe state all the time.

[0027] In the specific anti-loss-of-contact function, the emergency module continuously collects the location and status information of the system and encrypts and sends it to the cloud server. When the main battery fails or the main battery runs out of power, the system will detect the abnormality and enter the abnormal state. The MCU will control the function modules unrelated to the emergency module to turn off. At the same time, the MCU will control the emergency module to send a distress signal to the cloud server. In addition, since the solar power supply system is affected by the weather, if the sunlight is relatively weak and the solar power generation is less, the system controls to reduce the frequency of the emergency distress signal to reduce power consumption. When the sunlight is strong and the solar power generation is large, the system controls to increase the frequency of the emergency distress signal to increase power consumption.

[0028] When the solar energy is sufficient, it is necessary to discharge the excess electric energy converted and output. For this, this embodiment includes a surplus power release circuit 10. The surplus power release circuit 10 is connected between the output terminal of the solar charging management module 7 and the ground. The control terminal of the surplus power release circuit 10 is connected to the controller 4.

[0029] The specific circuit is as follows: The surplus power release circuit 10 includes an MOS transistor Q1 and a resistor R1. The drain of the MOS transistor Q1 is connected to the output terminal of the solar charging management module 7 through the resistor R1. The source of the MOS transistor Q1 is grounded. The gate of the MOS transistor Q1 is connected to the controller 4.

[0030] This embodiment can open the circuit to release the excess power to maintain the balance between power supply and consumption, so as to ensure that the system always works in a safe state. In practical applications, solar energy is a renewable clean energy, so the power of the system will be continuously supplemented, which can ensure that the shared electric scooter applying this system will never lose contact, avoid the waste of public resources, and also recover the loss of comprehensive value.

[0031] As a preferred method, the human-computer interaction unit 2 includes a communication module 11 and a display module 12. The communication module 11 and the display module 12 are respectively connected to the controller 4.

[0032] Based on the above system principle, this embodiment also proposes a shared scooter host, please refer to Figure 3 which includes a housing 13. The upper end of the housing 13 is fixed with an upper cover 14. The inner side of the upper cover 14 is provided with a circuit board 15. The circuit board 15 is provided with a human-computer interaction unit 2. The top of the upper cover 14 is embedded with a solar panel 1. A secondary battery 3 is provided below the circuit board 15. The human-computer interaction unit 2 includes an emergency system module 6 and a solar charging management module 7, wherein:

[0033] The solar panel 1 is used to convert solar energy into electric energy and charge the secondary battery 3 through the solar charging management module 7.

[0034] The emergency system module 6 is used to repeatedly send emergency signals to the server at preset time intervals.

[0035] The shared scooter main body is the head part of the scooter. Among them, a lower cover 16 is fixed inside the housing 13, the upper cover 14 is fixedly assembled opposite to the lower cover 16, and the circuit board 15 and the secondary battery 3 are accommodated in the cavity formed by the upper cover 14 and the lower cover 16.

[0036] In practical applications, the present invention connects the solar charging panel and the solar charging management module to the power supply system of the whole vehicle at the same time. The solar charging panel can convert conventional sunlight into electric energy to provide continuous power supplement for the whole system. After the main battery runs out of power, the electric energy converted by conventional sunlight can maintain the power of the secondary battery in a safe state, enabling the emergency system to repeatedly send emergency signals to the server at regular intervals. Due to the renewable energy, the emergency system will work permanently, perfectly solving the possible disconnection problem in the existing solutions on the market. At the same time, it will ensure that the lithium-ion battery will not enter an over-discharged state, avoiding the situation of damage to the internal structure of the battery due to power exhaustion, thereby reducing the safety hazards of the lithium battery.

[0037] The above are only the preferred embodiments of the present invention and are not used to limit the present invention. Any modifications, equivalent replacements, or improvements made within the technical scope of the present invention shall be included in the scope protected by the present invention.
