[0022] like Figures 1 to 3 As shown, this embodiment proposes: a high-safety fuel tank cap, comprising a cover body 1 that can be flipped open and closed, and a monitoring assembly 4 fixedly mounted on the cover body 1;

[0023] It also includes a bracket 2 rotatably connected to the cover body 1, and a cover opening 3 fixed to the bracket 2. The cover body 1 rotates on the bracket 2 through a rotating shaft to close the cover opening 3.

[0024] The monitoring assembly 4 includes a housing 41 (such as Figure 2 As shown, a cavity is provided inside the housing 41);

[0025] A microcontroller 42 and a lithium battery 43 are installed in the housing 41 (according to the above, the microcontroller 42 and the lithium battery 43 are respectively installed in the cavity for shielding and good protection);

[0026] and a charging port 44 fixed on the housing 41, wherein the charging port 44, the lithium battery 43 and the microcontroller 42 are electrically connected in sequence (the charging port 44 may be a USB charging port, etc.), (the microcontroller 42 may be a LPC820 microcontroller or a Texas Instruments (TI) MSP430 series microcontroller, etc.);

[0027] The microcontroller 42 is provided with a sensor for sensing whether the cover 1 is turned over or not, and a wireless transceiver module (the model of the wireless transceiver module is: NRF24L01, etc.)

[0028] The sensor is an inclination sensor or the like (the model may be Murata Electronics - SCA61T series, a small low-power inclination sensor using MEMS technology);

[0029] When in use, the lithium battery 43 is powered by an external power source connected to the charging port 44, and the wireless transceiver module is connected in advance by the user's smart phone {the application program (App) therein}. When the cover body 1 is flipped over, the sensor senses that the cover body 1 is flipped over, and the microcontroller 42 controls the wireless transceiver module to transmit the information to the user's smart phone, so as to provide timely notification and reminder, thereby increasing safety. Embodiment 2:

[0030] like Figure 1 As shown, the difference from Example 1 is that it also includes an anti-fouling component 5 arranged on the shell 41, which is used to close and open the charging port 44 (that is, the charging port 44 is closed to prevent dirt accumulation and opened for charging).

[0031] In order to implement the above-mentioned anti-fouling component 5, it is proposed that Figure 1 As shown, the specific structure and composition of the anti-fouling component 5 can be as follows: the anti-fouling component 5 includes a flip sheet 52 fixed on the housing 41, a blocking block 53 and a protrusion 54 fixed to the flip sheet 52, the outer side of the blocking block 53 is fitted with the inside of the charging port 44 (the entire anti-fouling component 5 can be made of soft materials, such as rubber, etc.), and the flip sheet 52 is softly rotated to press the blocking block 53 into the charging port 44 for sealing, and then remove it to open;

[0032] When the blocking block 53 is fitted in the charging port 44, the protrusion 54 is exposed outside the charging port 44. The protrusion 54 is arranged on the outer side of the blocking block 53 in the direction where the blocking block 53 is not inserted into or removed from the charging port 44 (such as Figure 1 As shown, the blocking block 53 is not arranged on the outer side of the blocking block 53 facing the charging port 44 and facing away from the charging port 44, that is, it is arranged at the periphery of the two side ends to facilitate pulling the blocking block 53 out of the charging port 44).

[0033] The control method of the present invention is automatic control through a controller. The control circuit of the controller can be realized by simple programming by technicians in this field. The provision of power is also common knowledge in this field. The present invention is mainly used to protect mechanical devices, so the present invention will no longer explain the control method and circuit connection in detail.

[0034] The above shows and describes the basic principles and main features of the utility model and the advantages of the utility model. For those skilled in the art, it is obvious that the utility model is not limited to the details of the above exemplary embodiments, and can be implemented in other specific forms without departing from the spirit or basic features of the utility model. Therefore, no matter from which point of view, the embodiments should be regarded as exemplary and non-restrictive. The scope of the utility model is limited by the attached claims rather than the above description, and it is intended to include all changes within the meaning and scope of the equivalent elements of the claims. Any figure mark in the claims should not be regarded as limiting the claims involved.

[0035] In addition, it should be understood that although the present specification is described according to implementation modes, not every implementation mode contains only one independent technical solution. This description of the specification is only for the sake of clarity. Those skilled in the art should regard the specification as a whole. The technical solutions in each embodiment may also be appropriately combined to form other implementation modes that can be understood by those skilled in the art.
