Attached Figure Description

[0010] Figure 1 This is the front view of the present invention;

[0011] Figure 2 This is a side view of the present invention;

[0012] Figure 3 This is a schematic diagram of the structure of the present invention;

[0013] Figure 4 This is a partially enlarged view of the sealing assembly of the present invention. Detailed Implementation

[0014] like Figures 1-3 As shown, this fully automatic electronically controlled fuel tank cover assembly includes a fuel tank lock bracket 1, a face cover 2, a lock body seat 5, and a lock tongue 6. The lock tongue 6 is mounted on the lock body seat 5, the lock body seat 5 is connected to the face cover 2, the face cover 2 is hinged to the fuel tank lock bracket 1, and the fuel tank lock bracket 1 is connected to the motorcycle body.

[0015] like Figure 3 As shown, a motor 3 and a driven gear 10 are installed on the lock body seat 5. A driving gear 16 is connected to the output shaft of the motor 3. The driving gear 16 meshes with the driven gear 10. The driven gear 10 is connected to the transmission component 11. An eccentric column 17 is provided on the transmission component 11. The side of the lock tongue 6 opposite to the transmission component 11 has a transmission groove 60. The eccentric column 17 of the transmission component 11 is located in the transmission groove 60 of the lock tongue 6. A lock tongue return spring 13 is provided on the lock body seat 5 to drive the lock tongue 6 to move outward.

[0016] The working principle of this fully automatic electronically controlled fuel tank cover assembly is as follows: When the assembly is locked, the latch 6 moves outward under the action of the latch return spring 13, thus locking the latch 6. When unlocking is required, pressing the button on the control motor 3 causes the motor 3 to drive the drive gear 16 to rotate, which in turn drives the driven gear 10 to rotate. The driven gear 10 then drives the transmission component 11 to rotate, and the eccentric column 17 on the transmission component 11 moves the latch 6 inward within the transmission groove 60 of the latch 6, thus unlocking the latch 6 and allowing the cover 2 to open normally. With this structure, the fuel tank cover can be opened automatically simply by pressing the control button, eliminating the need to press the button, making operation more convenient.

[0017] In order to enable the automatic electric control oil tank cover assembly to form a seal with the oil tank, and enable the cover 2 to automatically pop up after being opened, a sealing assembly is installed on the outer circle of the lock body seat 5, and the sealing assembly is located between the lock tongue 6 and the cover 2, as shown in Figure 4 The sealing assembly comprises a sealing ring 8, a sealing movable seat 9, and a sealing spring 12. The upper end of the sealing movable seat 9 has an inwardly extending inner extension edge 90. The lock body seat 5 has a spring support surface 50. The sealing spring 12 is located between the inner extension edge 90 of the sealing movable seat 9 and the spring support surface 50 of the lock body seat 5. The lower end of the sealing movable seat 9 has an outwardly extending outer extension edge 91. The sealing ring 8 is sleeved on the outer extension edge 91 of the sealing movable seat 9. When the automatic electric control oil tank cover assembly is in a locked state, the sealing ring 8 is pressed at the oil tank opening, and at the same time, the sealing movable seat 9 compresses the sealing spring 12 to form a pre-tightening force. In this way, the sealing ring 8 forms a seal to prevent fuel from leaking from the oil tank opening. After unlocking, the sealing spring 12 drives the sealing movable seat 9 to reset under the action of the pre-tightening force. In this way, the cover 2 automatically pops up, and the oil filling personnel can conveniently open the cover 2 to fill oil.

[0018] Since the motor 3 drives the lock tongue 6 to move through the gear, if the motor 3 is overdriven, the gear will be damaged, and even the motor 3 will be burned out. In order to solve this problem, the driven gear 10 of the present application is an incomplete gear. When the motor 3 drives the driving gear 16 to over-rotate, since the driven gear 10 is an incomplete gear, the driving gear 16 only drives the driven gear 10 to rotate a part. This part is sufficient to unlock the lock tongue 6. If the motor 3 is overdriven, the driving gear 16 will only idle, and will not act on the driven gear 10, thereby protecting the motor 3.

[0019] In order to further control the rotation of the motor 3 driving the driven gear 10, a permanent magnet 7 is installed on the driven gear 10, and a Hall sensor 4 that can sense the permanent magnet 7 is installed on the lock body seat 5. The Hall sensor 4 is electrically connected with the motor 3. When the driven gear 10 rotates a set part, the Hall sensor 4 senses the permanent magnet 7. In this way, the Hall sensor 4 transmits a signal to the motor 3, and the motor 3 immediately stops rotating, thereby further protecting the motor 3.

[0020] Finally, it is worth mentioning that the transmission groove 60 of the lock tongue 6 of the present application is a long groove, and the transmission groove 60 has a space for allowing the eccentric column 17 to move left and right. When being pressed on the cover 2, the lock tongue 6 moves back under the action of the guide slope (the lock tongue 6 moves relative to the eccentric column 17, which is equivalent to the eccentric column 17 moving in the transmission groove 60). When the lock tongue 6 is aligned with the lock slot, the lock tongue 6 moves outward into the lock slot under the action of the lock tongue return spring 13, thereby realizing locking. In this case, the motor does not need to participate in locking, and the structure is more simple and reasonable.
