[0025] Depend on Figures 1 to 5 It can be seen that the waterproof charger for an electric bicycle described in this embodiment includes a charger body 1, a connector 2, and a connecting line 11 provided between the charger body 1 and the connector 2;

[0026] The charger comprises a housing 4, a terminal 41 arranged at the bottom of the housing 4, and a pressing block 5 arranged on the housing 4 for lifting and movement; the housing 4 is provided with a slot 42; a pressing plate 51 is arranged at the bottom of the housing 4 for lifting and movement; a rubber sealing pad 52 is arranged on the top of the pressing plate 51; one end of the pressing block 5 is movably and telescopically arranged in the slot 42; the other end of the pressing block 5 protrudes out of the bottom of the housing 4 and is connected to the pressing plate 51;

[0027] The charger further comprises a swing arm 6 ; the swing arm 6 is used to drive the pressing block 5 to move up and down; a flexible wire is provided between the terminal 41 and the connecting wire 11 ; the flexible wire is passed through the swing arm 6 .

[0028] Specifically, in the waterproof charger for electric bicycles described in this embodiment, a sealing groove 31 is provided in the socket 3 for cooperating with the rubber sealing gasket 52; when it is necessary to connect to the socket 3, firstly, the bottom of the shell 4 is inserted into the socket 3, so that the terminal 41 is connected to the socket 3, and the rubber sealing gasket 52 is moved to the position of the sealing groove 31, and then the swing arm 6 is rotated to move the pressure block 5 and the pressure plate 51 upward. In the process of the pressure plate 51 moving upward, the pressure plate 51 cooperates with the bottom of the shell 4 to squeeze the rubber sealing gasket 52, so that the rubber sealing gasket 52 is embedded in the sealing groove 31, so that the connector 2 and the socket 3 form a waterproof seal; since the rubber sealing gasket 52 is in a natural state during the plugging process, the rubber sealing gasket 52 does not contact the inner wall of the socket 3, and no additional plugging resistance is generated, making the plugging process easier to operate.

[0029] In the waterproof charger for electric bicycle described in this embodiment, the swing arm 6 is provided with a rotation shaft 61; the swing arm 6 is rotatably arranged in the slot 42 via the rotation shaft 61.

[0033] When the rubber sealing pad 52 moves to the position of the sealing groove 31, the swing arm 6 is rotated to make the rotating shaft 61 move to the top of the cam groove 62. Since the distance between the rotating shaft 61 and the bottom of the cam groove 62 is greater than the distance between the rotating shaft 61 and the top of the cam groove 62, the pressing block 5 drives the pressing plate 51 to move upward during the movement of the rotating shaft 61 to the top of the cam groove 62. During the upward movement of the pressing plate 51, the pressing plate 51 cooperates with the bottom of the shell 4 to squeeze the rubber sealing pad 52, so that the rubber sealing pad 52 is embedded in the sealing groove 31, so that the connector 2 and the socket 3 form a waterproof seal, forming the state shown in the figure; since the rubber sealing pad 52 is in a natural state during the plugging process, the rubber sealing pad 52 does not contact the inner wall of the socket 3, and no additional plugging resistance is generated, making the plugging process easier to operate.

[0034] In the waterproof charger for electric bicycles described in this embodiment, the swing arm 6 is provided with a first clamping arm 71 and a second clamping arm 72; the pressing block 5 is provided between the first clamping arm 71 and the second clamping arm 72; the first clamping arm 71 and the second clamping arm 72 are both provided with the cam groove 62; and a clearance groove 73 is formed between the first clamping arm 71 and the second clamping arm 72. Specifically, the above arrangement can make way for the pressing block 5 and enhance the stability of the lifting and lowering of the pressing block 5.

[0035] In the waterproof charger for electric bicycles described in this embodiment, the side wall of the swing arm 6 is provided with a fixing groove 8; a locking block 81 is movably provided in the fixing groove 8; a locking spring 82 is provided between the locking block 81 and the fixing groove 8; and the housing 4 is provided with a locking groove that cooperates with the locking block 81. In the waterproof charger for electric bicycles described in this embodiment, the locking groove includes an upper locking groove 43 and a lower locking groove 44; when the pressing block 5 is arranged parallel to the swing arm 6, the locking block 81 is locked with the upper locking groove 43; when the pressing block 5 is arranged perpendicular to the swing arm 6, the locking block 81 is locked with the lower locking groove 44.

[0036] Specifically, through the above arrangement, the positions of the swing arm 6 and the shell 4 can be fixed when the pressure block 5 and the swing arm 6 are arranged in parallel, and the positions of the swing arm 6 and the shell 4 can be fixed when the pressure block 5 and the swing arm 6 are arranged vertically.
