Problems solved by technology

[0003] The first is the charging problem. The battery of an ordinary lead-acid battery 48V electric vehicle is relatively heavy. It will be laborious and tiring to dismantle the battery and move it upstairs to charge every day; and some residents pull the charging cable from the upstairs to charge. Although this method saves labor , but the operation of retracting and releasing the charging cable is cumbersome, and the charging cable is easy to be entangled. If it is not put away, there are problems such as easy to be affected by moisture, aging, and great potential safety hazards.
[0004] The second is the problem of anti-theft. The theft of electric vehicles or batteries is relatively rampant. In professional electric vehicle theft, it takes less than 20 seconds to steal a car.

Embodiment 1

[0025] see figure 1 , figure 2 , image 3 and Figure 4 .

[0026] The retractable charging device of this embodiment includes a support frame 1, a rotating shaft 2, a bobbin 3, a lead screw 41, a lead screw nut 42, a lead screw guide rod 43 and a charging line 5, the rotating shaft 2 and the lead screw 41 They are all rotatably installed on the support frame 1, and the rotating shaft 2 and the lead screw 41 are parallel to each other. A power transmission mechanism is also provided between the rotating shaft 2 and the leading screw 41. The first pulley 81 and the second pulley 82 on the leading screw 41, and the drive belt 83 wound around the outside of the first pulley 81 and the second pulley 82, the bobbin 3 is fixed on the rotating shaft 2, so The lead screw guide rod 43 is fixed on the support frame 1 and is parallel to the lead screw 41, the lead screw nut 42 is screwed on the lead screw 41 and slides through the lead screw guide rod 43, and the lead screw nut 42 i...

Embodiment 2

[0036] see Figure 5 , Figure 6 and Figure 7 .

[0037] The structure of the retractable charging device of this embodiment is similar to that of Embodiment 1, the only difference is that this embodiment does not have an electric telescopic rod, a power plug and a power socket to turn on and off the power supply, but uses a side frame far away from the motor 6 12. A support block 16 is arranged on the top surface of the support block 16. Two conductive stators 101 arranged vertically at intervals are arranged on the top surface of the support block 16. The two conductive stators 101 are respectively connected to the positive and negative poles of the power supply. One end of the motor 6 protrudes from the first ear plate 13 and extends between the two conductive stators 101, and the opposite sides of one end of the rotating shaft 2 are covered with conductive plates 102 respectively. The positive and negative poles at the inner end are respectively connected to the two co...

Abstract

The invention discloses a retractable charging device which comprises a support, a rotary shaft, a winding reel, a lead screw, a lead screw nut, a lead screw guide rod and a charging line. The rotary shaft and the lead screw are rotationally installed on the support, the rotary shaft is parallel to the lead screw, a power transmission mechanism is further disposed between the rotary shaft and the lead screw, the winding reel is fixed to the rotary shaft, the lead screw guide rod is fixed to the support and parallel to the lead screw, the lead screw nut is screwed on the lead screw and penetrates through the lead screw guide rod in a sliding mode, a wire ring is further arranged on the lead screw nut, the charging line is wound on the winding reel, and the outer end of the charging line penetrates through the wire ring and is connected with a charging plug. By means of the retractable charging device, winding and unwinding are smoother, the charging line can not be twisted, the retractable charging device is very easy to operate, the charging line can be quickly wound and unwound, the situation that residents upstairs work hard to transport storage batteries is avoided, and the problems that the charging line is prone to dampness and aging, and safety hidden hazards are large are solved.

Description

technical field [0001] The invention relates to a charging device, in particular to a retractable charging device. Background technique [0002] Electric bicycles have been popularized in urban and rural areas, but in most cities and township residential areas, the relevant supporting measures are not perfect, such as there is no uniformly guarded bicycle shed, or there is no supporting charging facility in the shed, or there are charges for parking and charging quite expensive. This makes many residents living upstairs encounter two troublesome problems: [0003] The first is the charging problem. The battery of an ordinary lead-acid battery 48V electric vehicle is relatively heavy. It will be laborious and tiring to dismantle the battery and move it upstairs to charge every day; and some residents pull the charging cable from the upstairs to charge. Although this method saves labor , but the operation of retracting and releasing the charging cable is cumbersome, and the ...
