Description

Technical Field

[0001] The utility model relates to the technical field of electric bicycle charging equipment, and more specifically, to a two-way fast charger for an electric bicycle. Background Art

[0002] With the widespread popularity of electric bicycles in modern life, the convenience of charging and energy conversion efficiency have increasingly become core bottlenecks affecting their further development. The chargers equipped with traditional electric bicycles are generally limited to a one-way charging mode, that is, they can only transmit electricity from the external power grid to the electric bicycle battery in one direction. This design undoubtedly reduces the flexibility and practicality of electric bicycles when they are far away from conventional power supply areas. At the same time, in daily use, electric bicycle users frequently encounter scenarios where they need to recharge their portable electronic devices during riding, or in specific situations, they hope to use the electric bicycle battery as an emergency or temporary power source to power other devices. These practical and urgent needs have strongly stimulated the in-depth exploration and research and development of new charging technology solutions. Therefore, they need to be improved and optimized. Utility Model Content

[0014] 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 embodiments described 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 making creative efforts are within the scope of protection of the present invention.

[0015] like Figures 1 to 3 As shown, the utility model provides a bidirectional fast charger for electric bicycles. The bidirectional fast charger consists of a battery, a controller box and a UPS box. The battery, the controller box and the UPS box are connected by a wiring harness. The controller box contains an electronic control module and a bidirectional DC / DC control module. The electronic control module consists of a microprocessor, a power control unit and a circuit protection unit. The bidirectional DC / DC control module specifically includes an MCU control module, a power control module and a circuit protection module.

[0016] By setting up a bidirectional DC / DC control module, users can use their mobile phone charger to perform low-power emergency charging for electric bicycles. Although the speed is relatively slow, it is enough to cope with emergencies and maintain the basic operating capabilities of the vehicle. The charger can also charge the battery and mobile phone at the same time. By utilizing the high efficiency and high-power output characteristics of the electric bicycle charger, the built-in intelligent distribution circuit can reasonably distribute the electrical energy to the battery and mobile phone, which not only ensures the charging needs of the electric bicycle, but also takes into account the user's demand for mobile phone power, greatly improving the comfort and peace of mind of travel. Especially in long-term outdoor activities or away from fixed power sources, mobile phones are important communication and navigation tools, and their power is also crucial. By charging the mobile phone and battery at the same time through the electric bicycle charger, users do not need to worry about losing contact or getting lost due to the depletion of the mobile phone power, providing a solid guarantee for travel safety.

[0017] The user first connects the e-bike charger to the charging port on the e-bike and then to an external power source (such as a household outlet). The charger then begins to work, converting AC power to DC power to charge the e-bike battery. When the e-bike battery is fully charged, the user can use a dedicated USB port to transfer the battery power to a mobile phone via a DC / DC module. If the e-bike battery is low and the user forgets to bring the e-bike charger, they can use their phone's charger, connect the phone to a UPS box via a wiring harness, and use the DC / DC module to charge the e-bike battery at a low power. If both the e-bike battery and the mobile phone are low on power, the user can use the e-bike charger, which intelligently distributes the power through the DC / DC module. The charger first connects to an external power source and then uses the DC / DC module to simultaneously charge the e-bike battery and the mobile phone.

[0018] There is a groove on the front of the UPS box, and a TYPE-C charging port and a USB charging port are set at the bottom of the groove. A conversion button is set on the top of the UPS box, and an indicator light is set on the side where the TYPE-C charging port and the USB charging port are close to each other.

[0019] By setting a groove on the front of the UPS box, the groove is not only equipped with a TYPE-C charging port, but also takes into account the traditional USB charging port, which improves the compatibility of the charger and can meet the charging needs of the vast majority of smart devices and electronic products on the market, including the latest mobile phones, tablets and some laptops that support the TYPE-C interface. It is also compatible with devices using standard USB interfaces, which brings great convenience to users. By setting indicator lights, it can display the charging status, such as charging, full or abnormal, so that users can grasp the charging status at any time, avoid damage to the device due to improper charging or overcharging, and ensure the safety and reliability of the charging process.

[0020] Among them, the wiring harness is provided with a branching head, which connects the positive line and the negative line. The ends of the positive line and the negative line are respectively provided with Y-shaped connectors, and the two Y-shaped connectors are fixedly connected to the power connection port of the battery through set screws.

[0021] By adopting a Y-shaped connector design at the ends of the positive and negative lines, the connection area can be increased, making the connection between the charger and the battery tighter and more stable. At the same time, the Y-shaped connector is fixed to the power connection port of the battery by a set screw, effectively preventing poor contact or short circuit problems caused by vibration or looseness during charging, ensuring the safety and reliability of the charging process.

[0022] Among them, box openings are provided at both ends of the controller box, and a box cover is provided at the port of the wiring harness, and the box cover is fixedly connected to the controller box by screws.

[0023] By providing box openings at both ends of the controller box and equipping the wiring harness port with corresponding box covers, the entire connection part is effectively sealed, which can effectively prevent the intrusion of external impurities such as dust and moisture. Especially when used outdoors or in humid environments, it can protect the internal circuit and connection components from damage, thereby extending the service life of the charger and enhancing durability.

[0024] The working principle and use process of this utility model:

[0025] The user first connects the e-bike charger to the charging port on the e-bike and then to an external power source (such as a household outlet). The charger then begins to work, converting AC power to DC power to charge the e-bike battery. When the e-bike battery is fully charged, the user can use a dedicated USB port to transfer the battery power to a mobile phone via a DC / DC module. If the e-bike battery is low and the user forgets to bring the e-bike charger, they can use their phone's charger, connect the phone to a UPS box via a wiring harness, and use the DC / DC module to charge the e-bike battery at a low power. If both the e-bike battery and the mobile phone are low on power, the user can use the e-bike charger, which intelligently distributes the power through the DC / DC module. The charger first connects to an external power source and then uses the DC / DC module to simultaneously charge the e-bike battery and the mobile phone.
