[0002] The instrument of an electric bicycle displays important riding data during the trip, such as speed, distance, battery life, and power gear, helping riders to read data and control power during riding. The instrument generally uses a TYPE-C interface for charging and data transmission, but the TYPE-C mother seat is very weak and vulnerable; when the TYPE-C mother seat is vacant, a dust plug is required to block dust and foreign matter. The TYPE-C seat dust plug is one of the important components of the TYPE-C seat on the instrument.

[0003] Defects of the prior art:

[0004] The dust plug of TYPE-C seat generally adopts a soft rubber structure; to ensure that the dust plug does not fall off, the anti-falling structure and the instrument housing generally adopt two matching methods:

[0005] 1) The anti-drop structure of the dust plug is placed in the inner cavity of the instrument housing through the local slot structure of the instrument housing. In this way, the surface of the housing is smooth and beautiful, but water will penetrate into the inner cavity of the housing through the local slot structure of the housing;

[0020] The present invention is further explained below in conjunction with the accompanying drawings and specific embodiments. The embodiments are implemented based on the technical solution of the present invention. It should be understood that these embodiments are only used to illustrate the present invention and are not used to limit the scope of the present invention.

[0021] like Figures 1 to 3As shown, the embodiment of the utility model provides a TYPE-C female seat dustproof structure, including a dust plug 2 arranged on the upper cover 1. A first groove 11 is provided at a position adjacent to one side of the upper side of the upper cover 1, and a through hole 12 is provided in the middle of the first groove 11. The through hole 12 is used for the mouth of the TYPE-C female seat 5 to pass through, thereby exposing the mouth of the TYPE-C female seat 3 in the first groove 11. A second groove 13 is provided on the upper side of the upper cover 1 outside the first groove 11, and the openings of the first groove 11 and the second groove 13 are both arranged on the upper side of the upper cover 1, and the width of the second groove 13 is smaller than the width of the first groove 11. A third groove 14 is provided on the side of the upper cover 1 outside the second groove 13, and the opening of the third groove 14 is arranged on the side of the upper cover 1, and the inner end of the third groove 14 is connected to the lower side of the outer end of the second groove 13, and the width of the third groove 14 is greater than the width of the second groove 13.
