Description

Technical Field

[0001] This utility model relates to the field of electric bicycle technology, specifically to an NFC key for electric bicycles. Background Technology

[0002] Electric bicycles are mechatronic personal transportation vehicles that use batteries as auxiliary power sources and are based on ordinary bicycles, but are equipped with motors, controllers, batteries, throttles, and other control components and display instrument systems.

[0003] Currently, electric bicycles are widely used in daily life as a convenient means of transportation. Traditional electric bicycles mostly use mechanical keys or remote control keys for unlocking and starting. Mechanical keys have problems such as being easy to lose and having a high risk of being copied. Moreover, it is inconvenient to insert the key into the keyhole in dark environments. Although remote control keys are relatively convenient to operate, they have problems such as being susceptible to signal interference and needing to replace the battery regularly. If the battery is dead, the bicycle cannot be used normally, causing many inconveniences for users. Utility Model Content

[0004] The purpose of this invention is to address the shortcomings of existing technologies by proposing an NFC key for electric bicycles.

[0005] To achieve the above objectives, the present invention adopts the following technical solution:

[0006] An NFC key for electric bicycles includes a key body with an NFC chip inside. The NFC chip stores information related to vehicle unlocking and starting, and interacts with an NFC sensing device on the electric bicycle. A battery is also inside the key body, and a charging slot is provided at the connection point between the key body and the battery. A control button and an indicator light are located at the top of the key body. The indicator light is electrically connected to the NFC chip. During NFC data interaction, the indicator light can display the interaction status through different light colors and flashing patterns, allowing the user to intuitively understand the operation result.

Compared with traditional mechanical keys and remote control keys, it is more convenient to operate. There is no need to search for the keyhole in the dark, and there is no need to worry about remote control signal interference. By setting control buttons and indicator lights, users can quickly trigger the NFC function through the control buttons and intuitively understand the NFC data interaction status according to the different display status of the indicator lights. The operation is more convenient and efficient, avoiding the trouble caused by not being able to judge the working status of the key.

[0015] 2. This NFC key for electric bicycles features a multi-layered protective structure, including a first rubber protective pad, a second rubber protective pad, a waterproof shell, and a waterproof silicone pad. This effectively enhances the key's waterproof and impact-resistant performance, enabling it to adapt to various complex environments, extending its service life, and improving its reliability.

[0022] The technical solutions of the present utility model will be clearly and completely described below with reference to the accompanying drawings of the embodiments of the present utility model. Obviously, the described embodiments are only some embodiments of the present utility model, and not all embodiments.

[0023] In the description of this utility model, it should be understood that the terms "upper", "lower", "front", "rear", "left", "right", "top", "bottom", "inner", "outer", etc., indicate the orientation or positional relationship based on the orientation or positional relationship shown in the accompanying drawings. They are only for the convenience of describing this utility model and simplifying the description, and do not indicate or imply that the device or element referred to must have a specific orientation, or be constructed and operated in a specific orientation. Therefore, they should not be construed as limitations on this utility model.

[0024] Example: An NFC key for electric bicycles, such as Figures 1-4 As shown, the device includes a key body 1, which contains an NFC chip 2. The NFC chip 2 stores information related to vehicle unlocking and starting, and interacts with the NFC sensing device on the electric bicycle. The key body 1 also contains a battery 3, and a charging slot 4 is located at the connection between the key body 1 and the battery 3. A control button 5 and an indicator light 6 are located on the top of the key body 1. The indicator light 6 is electrically connected to the NFC chip 2. During NFC data interaction, the indicator light 6 can display the interaction status through different light colors and flashing patterns, allowing the user to intuitively understand the operation results.

[0025] like Figures 1-4As shown, the upper end of the key body 1 is provided with a first rubber protective pad 7, the upper end of the first rubber protective pad 7 is provided with a first opening 8, the upper end of the first rubber protective pad 7 is provided with a second opening 9, and the lower end of the key body 1 is provided with a second rubber protective pad 10. The diameter of the first opening 8 is adapted to the control button 5, and the diameter of the second opening 9 is adapted to the indicator light 6. The outer side of the key body 1 is covered with a waterproof shell 11, and the side of the waterproof shell 11 is provided with a slot 12. When the user presses the control button 5 on the key body 1, the control button 5 triggers the circuit to conduct, powering the NFC chip 2 and activating its working state. The activated NFC chip 2 reads itself. The stored encrypted information related to vehicle unlocking and starting is sent to the NFC sensing device on the electric bicycle via an antenna (integrated in the NFC chip 2 or the internal circuit of the key body 1). The vehicle sensing device decodes, verifies, and authenticates the received signal. If the verification is successful, the vehicle is unlocked or started. Both the first rubber protective pad 7 and the second rubber protective pad 10 are made of highly elastic silicone material and have multiple protective functions. Firstly, they provide cushioning and shock absorption. When the key is accidentally dropped or subjected to external impact, the rubber protective pad absorbs the impact force through its own deformation, preventing damage to the precision components such as the NFC chip 2 and the battery 3 inside the key body 1 due to severe vibration.

[0026] like Figures 1-3 As shown, the upper end of the waterproof housing 11 is provided with a third opening 13 corresponding to the control button 5, and the upper end of the waterproof housing 11 is provided with a fourth opening 15 corresponding to the indicator light 6. A first waterproof silicone pad 14 is provided at the connection between the control button 5 and the third opening 13, and a second waterproof silicone pad 16 is provided at the connection between the indicator light 6 and the fourth opening 15. A fixing block 17 is provided at the front end of the waterproof housing 11, and a wire groove 18 is provided inside the fixing block 17. The waterproof housing 11, combined with the silicone pad, prevents moisture and dust from entering.

[0027] Working principle: When the user presses the control button 5 on the key body 1, the control button 5 triggers the circuit to conduct, powering the NFC chip 2 and activating its working state. The activated NFC chip 2 reads the encrypted information related to vehicle unlocking and starting stored in itself, and sends the data signal to the NFC sensing device on the electric bicycle through the antenna (integrated in the NFC chip 2 or the internal circuit of the key body 1). The vehicle sensing device decodes, verifies, and authenticates the received signal. If the verification is successful, the vehicle is unlocked or started, and the indicator light 6 is solid green. If the verification fails, the indicator light 6 flashes red to remind the user. When the battery 3 is below 20%, the indicator light 6 will flash yellow to remind the user to charge through the charging slot 4.

[0028] The above description is only a preferred embodiment of the present utility model, but the protection scope of the present utility model is not limited thereto. Any equivalent substitutions or changes made by those skilled in the art within the technical scope disclosed in the present utility model, based on the technical solution and the inventive concept of the present utility model, should be included within the protection scope of the present utility model.
