Description

Technical Field

[0001] This utility model relates to the field of motorcycle technology, and in particular to a motorcycle electronic fuel tank lock unlocking device. Background Technology

[0002] In the motorcycle industry, the locking method of the fuel tank cap plays a crucial role in vehicle safety and user convenience. Currently, the two main types of motorcycle fuel tank caps commonly found on the market are mechanical lock caps and electronically controlled lock caps.

[0003] Mechanical fuel tank caps have been widely used in the past due to their relatively high security. They involve inserting a mechanical key into the lock cylinder, turning the key to activate the internal locking mechanism, and opening or closing the fuel tank cap. This method can, to some extent, prevent the fuel tank cap from being easily pried open, ensuring the safe storage of fuel. However, it has significant inconveniences. Users need to carry the key at all times; if they forget to bring it or lose the key, they cannot open the fuel tank cap, causing considerable trouble for refueling and other operations. Electronic fuel tank caps are usually controlled by electronic signals. Users can unlock them remotely or at close range using a remote control, mobile app, or buttons on the vehicle, eliminating the need for a traditional key and greatly improving convenience. However, electronic systems rely on power supplies and have complex electronic components and programs, making them prone to malfunctions or failures. Therefore, existing motorcycle fuel tank cap locking methods, whether mechanical or electronic, have their own drawbacks and cannot simultaneously meet the requirements of security and convenience.

[0026] Please see Figures 1 to 6The diagram illustrates a preferred embodiment of a motorcycle electronic fuel tank lock unlocking device, comprising a fuel tank cap body 19, a bracket 1, a lock body 2, a latch 3, a lock cylinder 4, an electromagnet 5, a knob 6, a latch limiting cover 7, and a spare key 8. The fuel tank cap body 19 is mounted within the bracket 1 via a pin and can rotate relative to the bracket 1, which is mounted on the motorcycle's fuel tank. The lock body 2 is located on the fuel tank cap body 19 and contains the lock cylinder 4 and the electromagnet 5. The lock cylinder 4 has a lock hole 9 that engages with the electromagnet 5. Two latches 3 are located at the lower end of the lock cylinder 4, and a knob 6 is located at the upper end of the lock cylinder 4. The upper end of the knob 6 has a keyhole 20 that engages with the spare key 8. The latch limiting cover 7 is movably mounted on the outer side of the lock body 2. The lock body 2 is connected to the fuel tank cap body 19 by screws, which are installed from the inside of the fuel tank cap body 19 to prevent external removal of the screws, thus providing an anti-theft function.

[0027] A circuit board and a battery can be installed inside the lock body 2. The battery is connected to the circuit board, and the electromagnet 5 is also connected to the circuit board. A wireless module can be installed on the circuit board for connecting to an external mobile phone signal, allowing the electromagnet 5 to be powered on or off via an app or mini-program on a mobile phone. The structure of the electromagnet 5 in this embodiment is existing technology. The electromagnet 5 has an iron core. When the electromagnet 5 is energized, it attracts the iron core, causing the iron core to disengage from the lock hole 9 and releasing the lock cylinder 4. At this time, turning the knob 6 will drive the lock cylinder 4 to rotate, and the lock cylinder 4 will retract the two locking tongues 3 into the lock body 2, thereby unlocking the fuel tank cap body 19. The fuel tank cap body 19 can then be rotated to open the fuel tank cap.

[0028] In this embodiment, a locking groove that cooperates with the locking tongue 3 is provided inside the oil tank.

[0029] Inside the fuel tank, there is a protrusion that cooperates with the locking tongue limit cover 7. When the fuel tank cap body 19 is pressed down, the locking tongue limit cover 7 will abut against the protrusion. At this time, the locking tongue limit cover 7 will move upward relative to the lock body 2, releasing the restriction on the locking tongue 3. The locking tongue 3 will automatically pop out under the action of the locking tongue spring 14 and enter the locking groove, thereby locking the fuel tank cap body 19. At this time, the fuel tank cap body 19 cannot be opened.

[0030] Furthermore, as a preferred embodiment, a protruding ring 10 is provided on the inner wall of the latch limit cover 7, and a limiting block 11 is provided on the upper outer edge of the latch limit cover 7. The upper end of the latch limit cover 7 extends into the lock body 2, and a limiting groove for assembling the limiting block 11 is provided on the inner wall of the lock body 2. The protruding ring 10 is integrally formed with the latch limit cover 7 and is provided on the inner wall of the latch limit cover 7. It is mainly used to support the spring 12. The spring 12 is located inside the latch limit cover 7. The lower end of the spring 12 is connected to the upper end of the protruding ring 10, and the upper end of the spring 12 is in contact with the inner wall of the lock body 2. Under the action of the spring 12, the latch limit cover 7 can move downward relative to the lock body 2. When the latch 3 enters the latch limit hole 13, the spring 12 automatically pushes the latch limit cover 7 to move and blocks the latch limit hole 13 to prevent the latch 3 from protruding.

[0031] Furthermore, as a preferred embodiment, the lower end of the lock body 2 is provided with a latch limiting hole 13, which penetrates the lock body 2. Two latches 3 are disposed within the latch limiting hole 13, and the latches 3 can operably extend out of or enter the latch limiting hole 13. See also... Figure 3 As shown, the latch limiting hole 13 serves as a channel for the movement of the latch 3. The width of the latch limiting hole 13 is slightly larger than the width of the latch 3 to facilitate the movement of the latch 3, allowing the latch 3 to enter or exit the latch limiting hole 13.

[0032] Furthermore, as a preferred embodiment, it also includes a latch spring 14, with a telescopic rod 15 disposed between the two latches 3. The latch spring 14 is sleeved on the telescopic rod 15, and the two ends of the spring 12 abut against the two latches 3. In this embodiment, the two ends of the telescopic rod 15 can be hinged to the two latches 3. The latch spring 14 is disposed on the telescopic rod 15 to facilitate support of the latch spring 14. The latch spring 14 is used to push the two latches 3 out of the latch limiting hole 13.

[0033] Furthermore, as a preferred embodiment, each of the two latches 3 has a slot 16 at its closest point, and the two slots 16 face each other to form a slot. A insert 17 is provided at the lower end of the lock cylinder 4, and the insert 17 is disposed within the slot. See also Figure 5 and Figure 6 As shown, the length of the slot should be greater than the length of the insert 17, and the width of the slot should be greater than the width of the insert 17. This way, when the insert 17 rotates, both sides of the insert 17 can contact the inner walls of the two slots 16, which can drive the two latches 3 to move closer to each other and enter the latch limiting hole 13.

[0034] Furthermore, as a preferred embodiment, a micro switch 18 is also included, which is provided on one side of the fuel tank cap body 19. The micro switch 18 is connected to the circuit board, and when the fuel tank cap body 19 is opened, the micro switch 18 is turned on, sending a signal that the fuel tank is open.

[0035] When in use, an unlocking signal is sent via mobile phone. Upon receiving the signal, electromagnet 5 activates, attracting the iron core and disengaging it from lock hole 9, thus releasing the lock cylinder 4. Then, knob 6 is manually turned, causing lock cylinder 4 to rotate. Lock cylinder 4 then rotates insert 17, pushing the two bolts 3 into bolt limiting holes 13. At this point, bolt limiting cover 7 moves downward relative to lock body 2 under the action of spring 12, blocking bolt limiting holes 13 and preventing bolts 3 from extending. This completes the unlocking action. When locking, pressing down on the fuel tank cap body 19 causes the lower end of bolt limiting cover 7 to abut against a protrusion inside the fuel tank, moving the protrusion upward relative to lock body 2 and exposing bolt limiting holes 13. Bolts 3 then automatically extend from bolt limiting holes 13 under the action of bolt spring 14, entering the locking groove and locking the fuel tank cap.

[0036] The above description is only a preferred embodiment of the present utility model and does not limit the implementation method and protection scope of the present utility model. Those skilled in the art should realize that all solutions obtained by equivalent substitutions and obvious changes made based on the description and illustrations of the present utility model should be included within the protection scope of the present utility model.
