[0027] Specifically, the electric bicycle charger with a timing switch described in this embodiment has a first connector 11 connected to a plug for connecting to an external power source, and a second connector 2 connected to an electric bicycle for charging the electric bicycle.

[0028] When in use, first insert the second connector 2 into the interface 14, then start the timing switch 5, so that the driving component starts working, and the driving component drives the upper lifting seat 3 and the lower lifting seat 4 to approach each other, and fixes the second connector 2 with the top through the upper fixing component, and fixes the second connector 2 with the bottom through the lower fixing component, and the upper terminal 32 and the lower terminal 42 are respectively in contact with the second connector 2, so that the second connector 2 is locked between the upper fixing block 31 and the lower fixing block 41, which can effectively prevent the second connector 2 from being accidentally loosened or pulled out; when the timing switch 5 is charged at the time, or is used to press the timing switch 5 spontaneously, the upper lifting seat 3 and the lower lifting seat 4 can be separated again through the driving component, so that the second connector 2, the upper fixing block 31 and the lower fixing block 41 are unlocked, so that the second connector 2 is easy to take out.

[0029] In the electric bicycle charger with a timing switch described in this embodiment, the cross-sectional shape of the second connector 2 is circular; the cross-sectional shape of the upper fixing component and the cross-sectional shape of the lower fixing component are both semicircular. In the electric bicycle charger with a timing switch described in this embodiment, after the upper fixing component and the lower fixing component abut against each other, the second connector 2 is fixedly arranged between the upper fixing component and the lower fixing component. Specifically, the above arrangement can effectively fix the second connector 2 between the upper fixing block 31 and the lower fixing block 41.

[0030] In the electric bicycle charger with a timer switch described in this embodiment, the upper fixing assembly includes an upper fixing groove 33 provided on the upper fixing block 31, an upper fixing pin 34 which is telescopically provided on the upper fixing groove 33, and an upper spring 35 provided between the upper fixing pin 34 and the upper fixing groove 33; the telescopic movement direction of the upper fixing pin 34 is the same as the lifting movement direction of the upper fixing block 31; the top of the second connector 2 is provided with an upper clamping groove 21 which cooperates with the upper fixing pin 34. Specifically, during the descent of the upper lifting seat 3, the upper fixing pin 34 is inserted into the upper clamping groove 21, so that the upper fixing block 31 and the top of the second connector 2 can be locked.

Specifically, during the rising process of the lower lifting seat 4, the lower fixing pin 44 is inserted into the lower clamping groove 22, so that the lower fixing block 41 and the bottom of the second connector 2 can be locked.

[0032] The electric bicycle charger with a timing switch described in this embodiment, the driving assembly includes a bracket 6 arranged in the accommodating chamber 12, a push rod 7 slidably arranged on the bracket 6, a hinge block 71 arranged at one end of the push rod 7, an upper limit rod 36 arranged on the upper lifting seat 3 and a lower limit rod 46 arranged on the lower lifting seat 4; an upper connecting rod 37 is rotatably connected between one side of the hinge block 71 and the upper limit rod 36; the two ends of the upper connecting rod 37 are respectively rotatably connected to the hinge block 71 and the upper limit rod 36; the other side of the hinge block 71 is rotatably connected to the lower limit rod 46 by a lower connecting rod 47; the two ends of the lower connecting rod 47 are respectively rotatably connected to the hinge block 71 and the lower limit rod 46; the bracket 6 is provided with a switch assembly for driving the push rod 7 to slide.

[0033] Specifically, first insert the second connector 2 into the interface 14, and then start the timing switch 5, so that the coil 62 is energized. After the coil 62 is energized, the adsorption plate 72 can overcome the action of the reset spring 73 and move closer to the iron core 61, thereby allowing the upper lifting seat 3 and the lower lifting seat 4 to move closer to each other through the upper connecting rod 37 and the lower connecting rod 47.

[0034] When the timing switch 5 is charged at the specified time, or is used to press the timing switch 5 spontaneously, the coil 62 loses voltage, and under the action of the reset spring 73, the push rod 7 resets and moves away from the iron core 61, thereby moving the upper lifting seat 3 and the lower lifting seat 4 away from each other through the upper connecting rod 37 and the lower connecting rod 47.

[0035] In the electric bicycle charger with a timer switch described in this embodiment, the housing 1 is provided with a limit groove 8 along the height direction; the upper limit rod 36 is provided with an upper slider 38; the lower limit rod 46 is provided with a lower slider 48; the upper slider 38 and the lower slider 48 are respectively slidably arranged in the limit groove 8.

[0036] In the electric bicycle charger with a timer switch described in this embodiment, the number of the driving components is two; the two driving components are respectively arranged on both sides of the accommodating cavity 12. Through the above arrangement, the upper lifting seat 3 and the lower lifting seat 4 can be stably lifted and lowered.

[0037] Finally, it should be noted that the above embodiments are only used to illustrate the technical solution of the utility model, rather than to limit the protection scope of the utility model. Although the utility model has been described in detail with reference to the preferred embodiments, ordinary technicians in this field should understand that the technical solution of the utility model can be modified or replaced by equivalents without departing from the essence and scope of the technical solution of the utility model.
