[0030] See also Figure 1 The embodiment of the utility model provides an electronic transmission, including: a front transmission body 10, a driving module 20 and a charging module 30; the driving module 20 is installed on one side of the front transmission body 10 and is drivingly connected to the front transmission body 10; the charging module 30 is installed on the driving module 20, wherein the charging module 30 is provided with a charging terminal 31 located outside the driving module 20, the charging terminal 31 is connected to an external power source, and the external power source charges a rechargeable battery located on the frame through the charging module 30. In this embodiment, the charging module 30 is installed outside the driving module 20 on one side of the front transmission body 10, which is convenient for charging the rechargeable battery, and at the same time, it can effectively reduce the probability of the charging terminal 31 wading in the process of the speed-changing bicycle, and effectively improve the use safety of the charging terminal 31.

[0031] Further, such as Figure 2 As shown, the driving module 20 includes: a gear box 21 and a PCB board; the PCB board is installed in the gear box 21, the charging module 30 is electrically connected to the PCB board, and the charging terminal 31 is arranged on the gear box 21. In this embodiment, the driving module 20 also includes a motor (not shown in the figure) and a gear set (not shown in the figure). The working principle of the driving module 20 is: after the motor receives the start signal of the PCB board, it starts to work, the motor drives its motor shaft to rotate, the motor shaft further drives the input end of the gear set to rotate, and through the transmission of the gear set, finally drives the output end of the gear set to rotate, thereby controlling the front transmission body 10 to work.

[0032] like Figure 3 and Figure 4 As shown, the external power supply is electrically connected to the charging terminal 31 through the power cord module 40, and the power cord module 40 includes: a power cord interface 41 and a power cord 42; the power cord interface 41 is electrically connected to the charging terminal 31; one end of the power cord 42 is electrically connected to the power cord interface 41, and the other end is connected to the external power supply. In this embodiment, the charging terminal 31 can connect the power cord module 40 with the charging module 30 through the power cord interface 41, so as to transmit electrical energy to the rechargeable battery. Specifically, the rider only needs to insert one end of the power cord 42 into the power cord interface 41 and connect the other end to the external power supply to complete the charging process. Through such a charging method, the front transmission body 10 can be charged in time, and the charging process is more convenient and efficient. The rider can charge the external rechargeable battery at any time as needed to meet the use requirements of the front transmission body 10.

[0033] It should be noted that the power cord module 40 can be directly installed on the drive module 20 and electrically connected to the drive module 20. In this way, when charging the rechargeable battery, the power cord interface 41 can be directly electrically connected to the charging end 31 of the charging module 30 to complete the charging operation of the rechargeable battery. And because the power cord module 40 is directly installed on the drive module 20, the rider can charge the rechargeable battery anytime and anywhere.

[0034] Furthermore, a cover is provided on the charging terminal 31, and the cover is rotatably connected to the charging terminal 31, and a protrusion structure is provided on the cover. When the rechargeable battery needs to be charged, the rider only needs to hold the protrusion structure to open the cover, and after the cover is opened, the power cord interface 41 is connected to the charging terminal 31 to complete the charging operation; when the rechargeable battery does not need to be charged, the rider holds the protrusion structure to close the cover. The purpose of this design is to reduce the probability of the charging terminal 31 being affected by wading, and at the same time, it can effectively prevent the charging terminal 31 from being dirty due to dust and mud during riding, greatly improving the safety of the use of the charging terminal 31.

[0035] In this embodiment, a first buckle can also be provided between the cover and the charging terminal 31, a slot is provided on the cover, the bottom of the first buckle is rotatably connected to the charging terminal 31, and a buckle that cooperates with the slot is provided at the top of the first buckle towards the slot. When the rechargeable battery needs to be charged, the rider only needs to bend the buckle outward to open the cover, and after the cover is opened, the power cord interface 41 is connected to the charging terminal 31 to complete the charging operation; when the rechargeable battery does not need to be charged, the rider can close the cover by buckling the buckle inward.

[0036] Furthermore, the shape of the charging terminal 31 can be circular, rectangular, oval, etc., and the shape of the cover plate is adapted to the shape of the charging terminal 31, so that the cover plate completely covers the charging terminal 31, and better protects the charging terminal 31 from the influence of wading. A sealing ring can also be provided between the charging terminal 31 and the cover plate. When the rechargeable battery is charged, the sealing ring plays a role of waterproofing and corrosion resistance, preventing water or dust from entering, thereby better protecting the charging terminal 31.

[0037] In this embodiment, the charging module 30 is a magnetic charging module. The magnetic charging module is used to connect to an external power source through the power cord module 40 and charge the rechargeable battery. The charging module 30 may be a magnetic charging socket, and the power cord interface 41 may be a magnetic charging head, which is electrically connected to the magnetic charging socket. When the rechargeable battery is exhausted, the magnetic charging head (magnetic charging head is externally connected to power transmission) can be magnetically contacted with the magnetic charging socket, and the rechargeable battery can be charged through the power cord module 40.

[0038] In another embodiment, the charging module 30 is a USB charging module. Specifically, the charging module 30 can be a USB interface, and the power cord interface 41 can be a USB charging head. The rider can use the USB charging head to plug into the USB interface to connect to the charging terminal 31 of the front derailleur body 10. The circuit inside the charging module 30 will control the output of electric energy and the charging process according to the charging requirements and the characteristics of the battery. The advantage of the USB charging module is that it is widely used in various devices and scenarios, has a standardized interface and charging protocol, and is compatible with a variety of charging devices.

[0039] Further, such as Figure 3As shown, the electronic transmission also includes: a communication module 50, and the communication module 50 is electrically connected to the rechargeable battery. The communication module 50 includes a communication interface 51, and the communication interface 51 is electrically connected to the PCB board. In this embodiment, when the front transmission body 10 adopts wireless communication, the communication interface 51 only has a charging function, that is, the communication interface 21 at this time is electrically connected to the rechargeable battery on the frame, and does not have a wired communication function. When the front transmission body 10 adopts a wired communication function, it has both wired communication and charging functions, that is, the communication interface 51 must at least be electrically connected to the battery on the frame to achieve data transmission and communication with the front transmission body 10. The communication interface 51 can be a variety of types of interfaces, such as a serial port, Bluetooth, etc., which are used for data interaction and transmission of control instructions with the front transmission body 10. Through the communication module 50, the rider can connect to the front transmission body 10 through an external device or a mobile phone APP and control the gear shifting. The rider can send gear shifting instructions through the communication interface 51 to adjust the working state and speed of the front transmission body 10. The front transmission body 10 receives and analyzes the instructions sent by the communication module 50 to achieve precise control of the front transmission body 10.

[0040] Furthermore, the electronic transmission also includes: a designated light, which is electrically connected to the PCB board and installed on the gear box 21, and is used to indicate a signal. In this embodiment, an opening is provided on the gear box 21, and the indicator light extends outward through the opening. The indicator light is electrically connected to the PCB board and is used to indicate a signal. Specifically, the display of the indicator light is controlled by a program, and the light flashes when shifting gears, the indicator light flashes red during the charging process of the rechargeable battery, and the indicator light is always green when the rechargeable battery is full.

[0041] In this embodiment, the indicator light can also display information such as the power level of the rechargeable battery and the charging status. Specifically, a digital display screen can be set on the indicator light to display the battery power level. Each small light or number represents a specific power level. For example, when the battery is fully charged, all lights are on or a number of 100% is displayed, while when the battery is low, only one light is on or a lower number is displayed. The indicator light can also display the charging status of the battery, such as charging, fully charged, or abnormal charging. These states can be indicated by different light flashing frequencies, colors, or icons to facilitate the rider to understand the charging status and make timely preparations for charging.

[0042] In a specific application scenario, the PCB board is the main control board of the front transmission body 10, which is used to receive and transmit electrical signals to control the rotation of the drive module 20. When one end of the power cord 42 is connected to the power cord interface 41, the other end is connected to the rechargeable battery (the rechargeable battery can be installed on the bicycle frame or directly installed inside the gear box 21). The charging end 31 is electrically connected to the PCB board, and the power cord interface 41 is electrically connected to the charging end 31. When the charging module 30 is working, the rechargeable battery is charged through the PCB board and the power cord module 40. During the charging process, the indicator light flashes red to indicate that charging is in progress. When it is full, the indicator light flashes green to indicate that charging is complete.

[0043] Further, such as Figure 5 As shown, the gearbox 21 includes an upper gearbox shell 211 and a lower gearbox shell 212. The upper gearbox shell 211 and the lower gearbox shell 212 are fixedly connected by a plurality of connecting members 22 arranged on the side, so that the gearbox 21 is more firmly installed on one side of the front transmission body 10 and provides power to the front transmission body 10, thereby realizing the shifting function of the speed-changing bicycle.

[0044] The utility model also provides a speed-changing bicycle, comprising a bicycle body and the electronic transmission as described above. The front transmission body 10 is connected to the gear box 21, receives signals through the communication module 50, realizes automatic or manual shifting operation, and drives the movement of the gears through the motor, thereby realizing the speed-changing function.

[0045] Furthermore, the speed-changing bicycle also includes a rear transmission body, which is usually installed on the rear wheel axle of the speed-changing bicycle, close to the wheel; the front transmission body 10 is installed at the bottom pipeline on the speed-changing bicycle frame, close to the pedal. In this embodiment, the charging module 30 is installed on the front transmission body 10. During the travel of the speed-changing bicycle, the probability of the front transmission body 10 wading through water is lower than that of the rear transmission body, and the use environment is better than that of the rear transmission body, which effectively improves the use safety of the charging terminal 31, and the probability of failure of the charging terminal 31 is relatively reduced.
