The experimental methods in the following embodiments are all conventional methods unless otherwise specified, and the materials, reagents, etc. used in the following embodiments can be obtained from commercial channels unless otherwise specified.
[0020] Embodiment 1:
[0021] As Figures 1 - 3 shown, a waterproof charging interface structure for an electric bicycle includes an electric vehicle charging part 1 and a waterproof mechanism. The waterproof mechanism includes a plug-in port 14. The plug-in port 14 is opened on one side surface of the electric vehicle charging part 1. A charging head 20 is inserted inside the plug-in port 14. A power cord 2 is provided at the input end of the charging head 20. A waterproof protective case 3 is movably connected to the outside of the power cord 2. A connection slot 10 is opened on the outside of the electric vehicle charging part 1. One end of the waterproof protective case 3 is movably inserted into the inside of the connection slot 10, and the waterproof protective case 3 covers the outside of the charging head 20. Heat dissipation holes are opened at equal distances at the bottom end of the waterproof protective case 3, and a positioning component is provided at the connection between the waterproof protective case 3 and the connection slot 10; The positioning component includes an empty slot 11. The empty slot 11 is opened inside the connection slot 10. A spring 12 is provided inside the empty slot 11. A positioning slider 13 is provided at the other end face of the spring 12. A positioning groove 31 is opened on the outside of the waterproof protective case 3. One end of the positioning slider 13 is movably connected to the inside of the positioning groove 31;
[0022] An electric bicycle refers to a means of transportation that uses a battery as an auxiliary energy source and is equipped with a motor, a controller, a battery, a handlebar, a brake handle and other control components and a display instrument system on the basis of an ordinary bicycle. Different from an ordinary bicycle, an electric bicycle needs to be charged;
[0023] At present, the charging shed in the community only has a shed on the top to block rain. In the case of slightly heavy rain, rainwater will splash on the charging electric bicycle. If too much rainwater seeps into the charging port, it will cause damage to components such as the battery;
[0024] Align the charger 20 with the power socket 14, insert the waterproof protective case 3 into the connection slot 10. When the charger 20 enters the power socket 14 to start charging, the waterproof protective case 3 presses against the positioning slider 13. The positioning slider 13 applies force to the spring 12, causing the spring 12 to contract. The positioning slider 13 temporarily returns to the inside of the empty slot 11 until the position of the positioning slider 13 overlaps with that of the positioning groove 31. Then the spring 12 extends and pushes the positioning slider 13 into the positioning groove 31, ensuring that the waterproof protective case 3 is fixed within the connection slot 10. Thus, the waterproof protective case 3 protects the working charger 20, and the heat dissipates through the heat dissipation holes at the bottom end of the waterproof protective case 3.
[0025] This protects the charging part of the electric bicycle during charging, preventing rainwater from seeping into the power socket 14 and damaging the components in the vehicle. At the same time, the structure of this mechanism is simple, and there are also heat dissipation holes, so that the charger 20 and the power socket 14 will not be damaged due to heat accumulation, making it more practical.
[0026] In other embodiments, this embodiment discloses that, as shown in Figure 2 On the top end face of the waterproof protective case 3, there are anti-slip cross bars 30, which are arranged at equal distances around the top end face of the waterproof protective case 3. Through this design, the friction degree of the waterproof protective case 3 during use is higher, improving the user experience.
[0027] In other embodiments, this embodiment discloses that, as shown in Figure 1 There are eight empty slots 11 arranged around the inside of the connection slot 10, and the number of springs 12, positioning sliders 13 is the same as that of the empty slots 11. Through this design, the connection tightness between the waterproof protective case 3 and the connection slot 10 can be improved, making the user experience of the waterproof protective case 3 better.
[0028] Embodiment 2:
[0029] In other embodiments, this embodiment discloses that, as shown in Figure 1 、 Figure 4 It further includes a connection mechanism. The connection mechanism includes a fixed sleeve 21 sleeved on the outside of the power cord 2. Inside the waterproof protective case 3, there is a connection sliding sleeve 32, which is movably connected to the outside of the fixed sleeve 21. And inside the connection sliding sleeve 32, there is a connection slider 33. On the outside of the fixed sleeve 21, there is a connection chute 22. At both ends inside the connection chute 22, there are first magnetic blocks 23. On both sides of the connection slider 33, there are second magnetic blocks 34, and the first magnetic blocks 23 and the second magnetic blocks 34 are magnetically connected.
[0030] When using the waterproof protective case 3, push the waterproof protective case 3 in the corresponding direction. The connecting sliding sleeve 32 slides on the outside of the fixed sleeve 21, and the connecting slider 33 is slidably connected to the inside of the connecting chute 22. When the waterproof protective case 3 is in different states, the connecting sliders 33 on both sides respectively contact the second magnets 34 at different positions on the inside of the connecting chute 22; this protects the charging part of the electric bicycle being charged and prevents rainwater from seeping into the power socket 14 and damaging the components in the vehicle. At the same time, the structure of this mechanism is simple, and there are also heat dissipation holes, so that the charger 20 and the power socket 14 will not be damaged due to heat accumulation, and the practicality is higher.
[0031] In other embodiments, this embodiment discloses, please refer to Figure 1 , Figure 4 As shown, the connecting sliders 33 are annularly distributed around the inside of the connecting sliding sleeve 32, and the number of the connecting chutes 22 is the same as that of the connecting sliders 33; through this design, the connection between the waterproof protective case 3 and the fixed sleeve 21 is more stable.
[0032] The above describes the embodiments of the present invention in detail with reference to the accompanying drawings. However, the present invention is not limited to this. Various changes can be made without departing from the spirit of the present invention within the scope of knowledge possessed by those skilled in the art to which the present invention pertains.
