[0002] With the widespread use of battery bicycles, chargers as important supporting equipment have also been widely used. At present, battery bicycle chargers are generally provided with heat dissipation holes to ensure that the charger can dissipate heat in time during the charging process to ensure normal operation.

[0003] However, in actual use, the filters on the heat dissipation holes often accumulate dust and debris. This brings many adverse effects. First, the accumulated dust and debris seriously affect the heat dissipation effect of the charger, causing the internal temperature of the charger to rise. Excessive internal temperature of the charger will further affect the performance of the charger, reduce charging efficiency, and may even damage internal electronic components and shorten the service life of the charger. Secondly, existing chargers with cleaning functions on the market usually require users to clean them manually. This method is cumbersome to operate, which not only increases the user's usage burden, but also often has poor cleaning effects. Users may not clean in time due to negligence or trouble, resulting in the continued existence of the charger's heat dissipation problem, further exacerbating the impact on the charger's performance and life.

DETAILED DESCRIPTION

[0019] The present invention is further described in conjunction with the following examples.

[0020] Depend on Figures 1 to 8 It can be seen that the electric bicycle charger with automatic cleaning function described in this embodiment includes an upper shell 11 and a lower shell 12; a power line 13 is arranged between the upper shell 11 and the lower shell 12; a heat dissipation port 21 is penetrated by the upper shell 11; and a filter 22 is arranged on the heat dissipation port 21; The upper shell 11 is penetrated by a channel 23; the channel 23 is telescopically provided with a cleaning rod 3; one end of the cleaning rod 3 is provided with a movable rod 4; the lower shell 12 is provided with a bracket 5; the bracket 5 is provided with a cleaning drive mechanism for driving the movable rod 4 to move up and down and rotate; The bracket 5 is rotatably provided with a winding roller 6 ; one end of the power cord 13 protrudes out of the upper shell 11 and the lower shell 12 ; the other end of the power cord 13 is wound around the winding roller 6 .

[0021] Specifically, the electric bicycle charger with automatic cleaning function described in this embodiment can dissipate heat for the circuit board below the bracket 5 by providing a heat dissipation port 21, and can prevent dust and debris from entering the electric bicycle charger through the heat dissipation port 21 by providing a filter 22; in addition, by providing a cleaning rod 3, a movable rod 4 and a cleaning drive mechanism, the cleaning drive mechanism drives the movable rod 4 to rise, so that the cleaning rod 3 rises from the channel 23 to above the filter 22, and then the cleaning drive mechanism drives the movable rod 4 to rotate. During the rotation of the movable rod 4, the cleaning rod 3 can clean the dust and debris on the surface of the filter 22, thereby ensuring the performance and life of the charger.

[0022] In the electric bicycle charger with automatic cleaning function described in this embodiment, the heat dissipation port 21 and the filter 22 are both fan-shaped structures; the movable rod 4 is arranged at the center of the heat dissipation port 21 and the filter 22. Specifically, through the above arrangement, when the cleaning drive mechanism drives the movable rod 4 to rotate, the cleaning rod 3 can clean the entire surface of the filter 22 in a swinging manner, and the heat dissipation port 21 with a fan-shaped structure enables the charger to have a larger heat dissipation area.

[0023] In the electric bicycle charger with automatic cleaning function described in this embodiment, a cleaning strip 31 is provided at the bottom of the cleaning rod 3; the cleaning strip 31 is used to abut against the top of the filter 22. In the electric bicycle charger with automatic cleaning function described in this embodiment, a cleaning box 32 is provided at the bottom of the channel 23 of the upper shell 11; a cleaning agent is provided in the cleaning box 32; and the cleaning strip 31 is movably provided at the top of the cleaning box 32.

[0024] Specifically, when the cleaning rod 3 is retracted into the channel 23 , the cleaning strip 31 is disposed in the cleaning box 32 , and the cleaning agent enables the cleaning strip 31 to better clean the filter screen 22 .

[0025] The electric bicycle charger with automatic cleaning function described in this embodiment, the cleaning drive mechanism includes a friction roller 7 rotatably arranged on a bracket 5 and a limit frame 8 fixedly arranged on the bracket 5; the limit frame 8 is provided with a limit rod 81 at the top of the friction roller 7; the middle part of the friction roller 7 is provided with a driving cavity 71 along the height direction; the movable rod 4 is movably arranged in the driving cavity 71. The electric bicycle charger with automatic cleaning function described in this embodiment, the inner wall of the driving cavity 71 is provided with a spiral groove 72; the outer wall of the movable rod 4 is provided with a driving pin 41; the driving pin 41 is movably arranged in the spiral groove 72; the outer wall of the movable rod 4 is provided with a horizontal groove 42 and a vertical groove 43; the vertical groove 43 is arranged at the top of the horizontal groove 42; the bottom of the vertical groove 43 is connected with one end of the horizontal groove 42; the limit rod 81 is movably arranged between the horizontal groove 42 and the vertical groove 43. In the electric bicycle charger with automatic cleaning function described in this embodiment, a first coil spring 73 is provided between the friction roller 7 and the bracket 5; the power cord 13 includes multiple friction sections 14 and multiple smooth sections 15; the multiple friction sections 14 and the multiple smooth sections 15 are arranged alternately; the power cord 13 abuts against the friction roller 7; wherein the friction section 14 can be a plurality of striped grooves arranged in parallel; Specifically, when the power cord 13 is in the storage state, the power cord 13 abuts against the outer walls of the upper shell 11 and the lower shell 12; when in use, the power cord 13 can be pulled outward according to the actual length required, and when the friction section 14 passes through the friction roller 7, the driving pin 41 is located at the bottom of the spiral groove 72, and the limiting rod 81 is located at the top of the vertical groove 43. When the friction section 14 drives the friction roller 7 to rotate, the cooperation between the limiting rod 81 and the vertical groove 43 hinders the rotation of the movable rod 4. Therefore, when the friction roller 7 rotates, the driving pin 41 moves along the spiral groove. 72 moves, thereby driving the movable rod 4 to rise, so that the cleaning rod 3 rises from the channel 23 to the top of the filter screen 22; when the driving pin 41 moves to the top of the spiral groove 72, the limiting rod 81 is located at the bottom of the vertical groove 43, that is, one end of the horizontal groove 42. When the friction roller 7 continues to rotate, since the driving pin 41 abuts against the top of the spiral groove 72, the friction roller 7 drives the movable rod 4 to rotate, and the limiting rod 81 moves along the horizontal groove 42, thereby driving the cleaning rod 3 to clean the surface of the entire filter screen 22 in a swinging manner.

[0026] When the smooth section 15 passes through the friction roller 7, the friction force between the friction roller 7 and the power cord 13 is lost, and the movable rod 4 is reset under the action of the first coil spring 73, that is, after the movable rod 4 drives the cleaning rod 3 to rotate to the top of the channel 23, the movable rod 4 drives the cleaning rod 3 to descend, so that the cleaning rod 3 is re-stored into the channel 23.

[0027] In the present embodiment, when the power cord 13 is pulled out, when the friction section 14 passes through the friction roller 7, the cleaning rod 3 is extended and then swings on the surface of the filter 22 to clean the filter 22. When the smooth section 15 passes through the friction roller 7, the cleaning rod 3 is reset and swung in the opposite direction and then rotated to the top of the channel 23, and then retracted into the channel 23. When the power cord 13 is continuously pulled out, the filter 22 can be continuously cleaned.

[0028] In the electric bicycle charger with automatic cleaning function described in this embodiment, a ratchet 61 is provided on the top of the winding roller 6; the ratchet 61 is coaxially arranged with the winding roller 6; a second coil spring 62 is provided between the winding roller 6 and the bracket 5; a ratchet 93 cooperating with the ratchet 61 is provided between the upper shell 11 and the lower shell 12. In the electric bicycle charger with automatic cleaning function described in this embodiment, a reset frame 9 is provided in the lower shell 12 for lifting and lowering movement; the ratchet 61 is connected to the reset frame 9; a spring 91 is provided between the top of the reset frame 9 and the upper shell 11. In the electric bicycle charger with automatic cleaning function described in this embodiment, a handle 92 is provided on the top of the upper shell 11 for lifting and lowering movement; the handle 92 passes through the upper shell 11 and is connected to the top of the reset frame 9.

[0029] Specifically, when using the electric bicycle charger with automatic cleaning function described in this embodiment, the user can pull out the power cord 13 according to the actual length needed, and at the same time the second coil spring 62 gradually stores energy, and due to the cooperation of the ratchet 61 and the ratchet teeth 93, the power cord 13 and the second coil spring 62 will not reset.

[0030] When the power cord 13 needs to be stored, the user can pull the handle 92 upwards, so that the reset member drives the ratchet 93 to move upwards, causing the ratchet 61 and the ratchet 93 to lose coordination. At this time, the winding roller 6 is reset under the action of the second coil spring 62, and the power cord 13 is rewound into the winding roller 6. Since the drive pin 41 is located at the bottom of the spiral groove 72 and the limit rod 81 is located at the top of the vertical groove 43, the friction roller 7 will not be driven to rotate during the resetting of the power cord 13.

[0031] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the present invention, rather than to limit the scope of protection of the present invention. Although the present invention has been described in detail with reference to the preferred embodiments, those skilled in the art should understand that the technical solution of the present invention can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the present invention.
