Description

Technical Field

[0001] The present invention relates to the technical field related to electric bicycle accessories, and in particular to an anti-misinsertion electric bicycle charging interface and a use method thereof. Background Art

[0002] The electric bicycle charging interfaces currently on the market present significant safety risks in actual use. Charging interfaces of different brands or models are highly similar in appearance, making it difficult for users to visually distinguish interface specifications, resulting in frequent mis-insertion of mismatched chargers. Once mis-inserted, serious safety incidents such as circuit short circuits, battery overcharge and damage, and even fire can easily occur. Furthermore, existing charging interfaces generally lack a mechanical anti-mock structure design and rely solely on the user's subjective identification of the interface type. This protection method has obvious shortcomings in terms of operational convenience and reliability, and cannot effectively avoid the risk of mis-insertion at the structural level, making it difficult to meet the actual needs of electric bicycle charging safety. Summary of the Invention

[0003] The purpose of the present invention is to solve the shortcomings of the prior art and to propose an anti-misinsertion electric bicycle charging interface.

[0004] In order to achieve the above object, the present invention adopts the following technical solutions: A charging interface for an electric bicycle that prevents mis-insertion, comprising a charging interface, a charging plug, a protrusion, a groove, a cover, a paddle, a first magnet, a second magnet, and a mounting hole. A charging plug is inserted into one end of the charging interface, and protrusions are fixedly connected to the four end surfaces of the inner wall of the charging interface. Grooves are formed on the four end surfaces of the outer wall of the charging plug, and multiple grooves are respectively in contact with corresponding protrusions. Multiple protrusions and grooves are all rectangular and compatible.

[0005] Preferably, the charging port is rotatably connected to a cover body, and the cover body is fixedly connected to a first magnet.

[0006] Preferably, the charging port is fixedly connected to a second magnet.

[0007] Preferably, one end and the other end of the charging interface are fixedly connected with mounting holes.

[0008] Preferably, the first magnet and the second magnet are magnetically attracted to each other.

[0009] Preferably, the cover is fixedly connected with a paddle.

[0010] Preferably, the plurality of grooves pass through one end and the other end of the charging plug.

[0011] A method for using an electric bicycle charging interface to prevent mis-insertion, comprising the following steps: S1. Interface protection: In the non-charging state, the cover is closed by magnetic attraction between the first magnet and the second magnet of the charging interface, covering the insertion end of the charging interface; S2. Opening the cover: overcoming the magnetic attraction by moving the cover's paddle, so that the cover rotates around the charging port (1) to open; S3. Anti-misinsertion operation: Align the groove of the charging plug with the protrusion on the inner wall of the charging port. Only when the rectangular outline and position of the groove and the protrusion are completely matched, insert the charging plug into the charging port; S4, charging execution: the protrusion is embedded in the groove to complete the mechanical interlocking and the charging operation is carried out; S5. Reset protection: After charging is completed, unplug the charging plug and the cover will automatically close and reset due to the magnetic attraction of the first magnet and the second magnet.

[0012] In step S3, the grooves penetrate the structural guide protrusions at both ends of the charging plug and are fully embedded until the charging plug is fully inserted.

[0013] In step S5, the closing operation of the cover body is automatically completed by the magnetic attraction without manual intervention.

[0014] The beneficial effects of the present invention are: 1. By coordinating the charging interface, charging plug, protrusions, and grooves, multiple protrusions are provided within the charging interface, and matching grooves are provided at the corresponding positions of the charging plug. This structurally addresses the safety hazards of existing interfaces. The charging plug can only be successfully inserted when its specifications are completely consistent with the interface, avoiding mis-insertion problems caused by similar interface appearances. Without relying on subjective user identification, the anti-mis-insertion function is achieved through physical structural adaptation, which can reduce the risk of circuit short circuits and battery damage caused by the insertion of mismatched chargers. This fundamentally improves the safety and reliability of the charging interface, while reducing equipment failures and safety accidents caused by mis-insertion, providing more operational structural protection for electric bicycle charging safety. 2. Through the coordination between the charging port, the cover, the first magnet and the second magnet, the cover is connected to the charging port by rotation, so that the first magnet of the cover and the second magnet of the charging port form magnetic adsorption, which can automatically close the covering port in the non-charging state, blocking the intrusion of dust and rainwater to a certain extent, thereby extending the service life of the charging port and providing protection for the charging safety of the electric bicycle.

[0017] The technical solutions in the embodiments of the present invention will be clearly and completely described below in conjunction with the drawings in the embodiments of the present invention. Obviously, the described embodiments are only part of the embodiments of the present invention, rather than all the embodiments.

[0018] Example 1, reference Figures 1 to 5 , an anti-misinsertion electric bicycle charging interface, including a charging interface 1, a charging plug 2, a protrusion 3, a groove 4, a cover body 5, a paddle 6, a first magnet 7, a second magnet 8 and a mounting hole 9. The charging plug 2 is inserted into one end of the charging interface 1, and the four end surfaces of the inner wall of the charging interface 1 are fixedly connected with protrusions 3. The four end surfaces of the outer wall of the charging plug 2 are provided with grooves 4. Multiple grooves 4 are respectively in contact with corresponding protrusions 3. The cooperation between the protrusions 3 and the grooves 4 can also facilitate the guiding operation when the charging plug 2 is inserted into the charging interface 1. Multiple protrusions 3 and grooves 4 are all rectangular and adapted. A protrusion 3 is set in the charging interface 1, and the charging plug 2 is provided with an adapted groove 4. It can only be inserted when the specifications are consistent, preventing misinsertion, reducing the risk of short circuit, and improving the safety and reliability of the charging interface 1.

[0019] In this embodiment, the charging interface 1 is rotatably connected to a cover body 5, and the cover body 5 can rotate on the charging interface 1. The cover body 5 is fixedly connected to a first magnet 7, and the charging interface 1 is fixedly connected to a second magnet 8. One end and the other end of the charging interface 1 are fixedly connected to mounting holes 9, which are used to fix the interface on the body of the electric bicycle. The first magnet 7 and the second magnet 8 are magnetically attracted to each other. When the cover body 5 contacts the charging interface 1, the magnetic attraction of the first magnet 7 and the second magnet 8 can be used to shield the charging interface 1 with the cover body 5, reducing the chance of dust and rainwater entering the charging interface 1. The cover body 5 is fixedly connected to a paddle 6, and multiple grooves 4 run through one end and the other end of the charging plug 2, which can facilitate the insertion of the charging plug 2 at one end of the charging interface 1.

[0020] The working principle of this embodiment is as follows: when in use, in the non-charging state, the cover body 5 is magnetically attracted by the first magnet 7 and the second magnet 8 of the charging interface 1, automatically closing and covering the interface to prevent the intrusion of dust and rainwater; when charging is needed, the cover body 5 is rotated to open, and the charging plug 2 is aligned with the charging interface 1. It can only be inserted when the groove 4 of the charging plug 2 is adapted to the protrusion 3 in the charging interface 1, and anti-misinsertion is achieved through the mechanical structure; after charging is completed, the charging plug 2 is pulled out, and the cover body 5 can be magnetically attracted by the first magnet 7 and the second magnet 8 to cover the charging interface 1 again.

[0021] The present invention also relates to a method for using an electric bicycle charging interface to prevent mis-insertion, comprising the following steps: S1. Interface protection: In the non-charging state, the cover 5 is magnetically closed by the first magnet 7 and the second magnet 8 of the charging interface 1, covering the insertion end of the charging interface 1; S2. Open the cover: Overcome the magnetic attraction by moving the paddle 6 of the cover 5 to rotate the cover 5 around the charging port 1 to open it; S3. Anti-misinsertion operation: Align the groove 4 of the charging plug 2 with the protrusion 3 on the inner wall of the charging interface 1. Only when the rectangular outline and position of the groove 4 and the protrusion 3 are completely compatible, the charging plug 2 is inserted into the charging interface 1; in step S3, the groove 4 penetrates the structure at both ends of the charging plug 2 to guide the protrusion 3 to be fully embedded until the charging plug 2 is fully inserted.

[0022] S4, charging execution: the protrusion 3 is embedded in the groove 4 to complete the mechanical interlocking and the charging operation is performed; S5, reset protection: After charging is completed, unplug the charging plug 2, and the cover 5 automatically closes and resets due to the magnetic attraction between the first magnet 7 and the second magnet 8. In step S5, the closing operation of the cover 5 is completed automatically by the magnetic attraction without manual intervention.

[0023] The above description is only a preferred specific embodiment of the present invention, but the scope of protection of the present invention is not limited thereto. Any technician familiar with the technical field, within the technical scope disclosed by the present invention, who makes equivalent replacements or changes based on the technical solution and inventive concept of the present invention, should be covered by the scope of protection of the present invention.
