Description

Technical Field

[0001] This utility model relates to the field of electric-assisted bicycle technology, and in particular to a quick-release portable power supply structure that can be used to supply power to electric-assisted bicycles. Background Technology

[0002] Currently, the power systems of most e-bikes adopt a fixed integrated design, where the power system is fixedly locked into the frame. This technical architecture has significant application pain points. First, the rigid binding of the battery module to the frame structure limits energy replenishment methods. When battery capacity degrades or during long-distance riding, users cannot extend their range through quick battery swaps and can only rely on charging stations for a few hours of static charging. Second, in cross-border transportation scenarios, the International Air Transport Association (IATA) regulations for transporting vehicles containing lithium batteries create a structural conflict with fixed power systems. Existing battery removal processes require specialized tools and technicians, and the complexity of disassembly and installation severely restricts the convenience of product transportation. Third, the whole-machine charging mode suffers from low space utilization efficiency. Users of e-bikes with fixed integrated power systems must plan dedicated charging areas for the bulky vehicle, which conflicts with the trend of urban space-intensive development. A feasible solution is needed to address these issues. Utility Model Content

[0003] To address this problem, this utility model proposes a quick-release portable power supply structure for powering electric bicycles, including a portable power supply and a connector. A connecting block is provided on the side of the portable power supply, and a connecting groove is provided on the connector. The connecting block and the connecting groove are matched and correspond to each other, and the portable power supply is fixed to the connector through the connecting block and the connecting groove.

[0004] Furthermore, the connector is fixed to the frame of the electric bicycle.

[0005] Furthermore, the connecting block is I-shaped and slides in connection with the connecting groove.

[0006] Furthermore, reinforcing ribs are provided on the connecting block.

[0007] Furthermore, the power bank further includes a main body, a top cover, and a base. The top cover is located on the top of the main body, and the base is located on the bottom of the main body. The base has an electrical connection port, through which the connecting cable is electrically connected to the drive motor and controller of the electric-assisted bicycle.

[0008] Furthermore, a control module is installed on the base, which is electrically connected to the battery cell located inside the main body. The power supply has a capacity of less than 160Wh.

[0009] Furthermore, the top cover is equipped with a charging interface and a power display module, which are electrically connected to the control module.

[0010] Furthermore, the side of the connector has a through-hole for the pin. When the power bank's connector block is inserted into the connector slot, the horizontal position of the pin hole is at the top of the connector block.

[0011] Furthermore, it includes a pin, which is inserted into a pin hole when the power bank's connector block is inserted into the connector slot, thus preventing the connector block from sliding upwards.

[0012] Furthermore, a nut plug is provided at the other end of the pin hole relative to the pin insertion, and the end of the pin is threaded. When the pin is inserted into the pin hole, the thread engages with the internal thread of the nut plug to lock and fix it.

[0013] Compared with existing technologies, the advantages of this utility model are:

[0014] 1. The quick-release design allows for rapid removal or installation of the battery, improving the range of electric-assist bicycles.

[0015] 2. The power bank is designed with a capacity of less than 160Wh, making it easy to carry during cross-border transportation.

[0039] In the description of this utility model, "multiple" means two or more, unless otherwise explicitly specified.

[0040] In the description of this utility model, it should be noted that, unless otherwise explicitly specified and limited, the terms "installed," "equipped with," "sleeved / connected," "connected," etc., should be interpreted broadly. For example, "connection" can be a fixed connection, a detachable connection, or an integral connection; it can be a mechanical connection or an electrical connection; it can be a direct connection or an indirect connection through an intermediate medium; it can be a connection within two components. Those skilled in the art can understand the specific meaning of the above terms in this utility model based on the specific circumstances.

[0041] Please refer to Figures 1-5The quick-release power bank structure of this utility model comprises two main parts: a power bank 10 and a connecting base 20. The power bank 10 includes a body 12, a top cover 13, and a base 14. The top cover 13 is located on the top of the body 12, and the base 14 is located on the bottom of the body 12. A connecting block 11 is provided on the side of the power bank body 12, and the connecting base 20 has a connecting groove 21 that matches the connecting block 11. The power bank 10 is fixed to the connecting base 20 through the cooperation of the connecting block 11 and the connecting groove 21. More specifically, the connecting block 11 is designed with an I-shaped structure. Furthermore, a reinforcing rib 18 can be provided on the connecting block 11. The main purpose of the reinforcing rib 18 is to prevent the connecting block 11 from breaking due to impact when the vehicle falls over, thus preventing the power bank 10 from detaching from the connecting base 20. The reinforcing rib 18 strengthens the connection block 11.

[0042] During installation, the user can align the connector 11 of the power bank 10 with the opening of the connector slot 21, and then insert the connector 11 into the connector slot 21 horizontally until the connector 11 is fully inserted into the connector slot 21. Then, slide it down from top to bottom to form a sliding connection with the connector slot 21, thereby achieving the initial fixation of the power bank 10 and the connector 20.

[0043] In this embodiment, the connector 20 can be secured to the frame of the electric bicycle using screws or other fasteners through the fixing hole 23, thereby achieving a stable installation of the entire power supply on the bicycle.

[0044] The base 14 of the power bank 10 has an electrical connection port 15. The connecting cable (not shown in the figure) is electrically connected to the drive motor and controller of the electric-assisted bicycle through the electrical connection port 15, thereby providing power to the electric-assisted bicycle.

[0045] The base 14 also has a control module (not shown in the figure) inside. This control module (not shown in the figure) is electrically connected to the battery cell (not shown in the figure) located in the main body 12, and is used to control the charging and discharging process of the battery and communication with external devices.

[0046] The portable battery of this utility model has a capacity of less than 160Wh, more specifically 158Wh. This design complies with relevant international transportation regulations and is convenient for carrying during cross-border transportation. In terms of power, the portable power bank has a capacity of 5Ah and can support fast chargers up to 36V / 2A.

[0047] The power bank 10 also features a charging port 17 and a power display module 16 on its top cover 13. The charging port 17, a Type-C interface, is used to connect to an external power source for charging. This allows for both external charging of the power bank and reversible charging of external mobile devices such as smartphones or action cameras. The power display module 16 displays the remaining battery level, allowing users to easily monitor the battery status. Both the charging port 17 and the power display module 16 are electrically connected to a control module, which performs the corresponding functions.

[0048] To further enhance the stability of the connection between the power bank 10 and the connector 20, a pin hole 22 is provided on the side of the connector 20, penetrating the connector. When the connector block 11 of the power bank 10 is inserted into the connector slot 21, the horizontal position of the pin hole 22 is exactly at the top of the connector block 11. At this time, inserting the pin 30 into the pin hole 22 can restrict the connector block 11 from sliding upwards, preventing the power bank 10 from accidentally detaching from the connector 20.

[0049] A nut plug 40 is provided at the other end of the pin hole 22 opposite to the insertion end of the pin 30, and the end of the pin 30 is provided with a thread 31. When the pin 30 is inserted into the pin hole 22, the thread 31 engages with the internal thread of the nut plug 40 to fix it, thereby firmly fixing the pin 30 in the pin hole 22 and ensuring the reliability of the connection between the power supply 10 and the connector 20.

[0050] When using the quick-release power bank of this utility model, if the user needs to disassemble the power bank for charging, simply unscrew the pin 30 to release the lock on the connecting block 11, and then slide the power bank 10 horizontally to allow the connecting block 11 to slide out of the connecting groove 21. During installation, the operation is reversed: first slide the connecting block 11 into the connecting groove 21, then insert the pin 30 and tighten it to complete the installation of the power bank.

[0051] The quick-release design allows users to quickly remove or install batteries, significantly improving the range of e-bikes. When one power bank's capacity is low, users can quickly replace it with a fully charged one, without waiting for recharging. Furthermore, the power bank's capacity of less than 160Wh makes it more convenient for cross-border transportation, complying with relevant safety regulations. In addition, the quick-release structure facilitates separate charging of the battery, avoiding the space occupied by charging the entire bike and increasing charging flexibility.
