Description

Technical Field

[0001] This utility model relates to the field of electric vehicle technology, and in particular to a Bluetooth-based positioning device for two-wheeled electric vehicles. Background Technology

[0002] Electric bikes are a common mode of transportation, accounting for a very high percentage of short-distance commutes in cities. In densely populated areas such as shopping malls, supermarkets, and subway stations, electric bikes are often parked in designated areas. Because electric bikes are similar in design, their parking positions are often organized and aligned by management personnel, making it difficult for riders to find their bikes when returning to their original location. The conventional method is to press a remote control to locate the bike by sound; however, in noisy outdoor areas or in underground parking garages with many obstructions, traditional infrared remote controls are not very effective in helping riders find their bikes. Additionally, some GPS-based bikes can be located via an app, but due to accuracy issues, the location points are often inaccurate, further complicating the search. Utility Model Content

[0010] Preferably, the first and second indicator lights remain constantly lit in yellow after the Bluetooth connection is stable.

[0011] Preferably, after the distance is determined, the side closer to the first indicator light and the side farther away remains constantly green and lit, while the side farther away is turned off.

[0022] Example 1

[0023] like Figure 1 As shown, the present invention proposes a Bluetooth-based positioning device for a two-wheeled electric vehicle, which includes a first Bluetooth module and a second Bluetooth module integrated in the remote control key module 1.

[0024] The first Bluetooth module outputs signals in a first direction; the second Bluetooth module outputs signals in a second direction; the first direction and the second direction are opposite; preferably, the first direction and the second direction are the left and right sides of the remote control key module 1, respectively.

[0025] The remote key module 1 is provided with a first indicator light 4 for indicating the status of the first Bluetooth module and a second indicator light 5 for indicating the status of the second Bluetooth module; the remote key module 1 is provided with a control button 6 in the middle for controlling the operation of the first Bluetooth module and the second Bluetooth module.

[0026] After pressing control button 6, the first Bluetooth module first sends a signal to connect with the electric vehicle's built-in Bluetooth device and measures the RSSI signal strength R1 at the current location; then, the second Bluetooth module sends a signal to connect with the electric vehicle's built-in Bluetooth device and measures the RSSI signal strength R2 at the current location; the distances D1 and D2 are calculated based on the values ​​of R1 and R2, and the indicator light on the side with the closer distance is lit up when comparing the magnitudes of D1 and D2.

[0027] The distance calculation formula is:

[0028]

[0029] Where D is the calculated distance (m); RSSI is the received signal strength (dB); abs is the absolute value; A is the signal strength when the transmitter and receiver are 1 meter apart; and n is the environmental attenuation factor.

[0030] In this embodiment, the first indicator light 4 and the second indicator light 5 flash yellow during Bluetooth connection. After the Bluetooth connection is stable, the first indicator light 4 and the second indicator light 5 remain solid yellow. Once the distance is determined, the indicator light 4 and the second indicator light 5 will remain solid green on the side closer to the vehicle and off on the side farther away. The vehicle's location can be roughly determined based on the direction of the indicator lights, and a quick vehicle location function can be achieved in conjunction with the infrared remote control. Users can also hold the remote key module 1 and press the control button 6 multiple times at nearby locations to locate the vehicle based on the approximate range indicated by the indicator lights.

[0031] In this embodiment, as Figure 3As shown, the remote key module 1 is also equipped with an infrared-based unlock button 2 and a lock button 3. A hanging ring 11 is provided on the top of the remote key module 1 for easy attachment to a keychain. The remote key module 1 includes an upper shell 12 and a lower shell 13; a magnetic ring 15 is provided on the lower shell 13 for magnetic attraction with the upper shell 12. A snap-fit ​​cover 14 is provided on the lower shell 13; the cover 14 protects the battery compartment; removing the cover 14 allows for easy battery replacement of the remote key module 1, making it more convenient; when the remote key module 1 malfunctions, the magnetic attraction of the magnetic ring 15 allows the upper shell 12 and lower shell 13 to be easily disassembled for repair.

[0032] The embodiments of the present invention have been described in detail above with reference to the accompanying drawings. However, the present invention is not limited thereto. Various changes can be made within the scope of knowledge possessed by those skilled in the art without departing from the spirit of the present invention.
