The bottom of the groove of the second fixing bracket 230 is designed as an incomplete opening structure, so that when the second insulating positioning block 220 is accommodated inside, it will not slip out from the bottom of the groove. In addition, the first inner cavity 222 and the second inner cavity The cavity 224 is designed as a structure independent of each other, so that it will not cause a short circuit when it is used for accommodating the positive transmission group and the negative transmission group.
[0039] Please combine figure 2 , image 3 , Figure 4 As shown, the positive electrode transmission group 140 includes a positive electrode contact block 142 and a first conductive fixing pin 144, and the positive electrode contact block 142 is fixed in the first groove 122 of the first insulating positioning block 120 by the first conductive fixing pin 144; The set 150 includes a negative electrode contact block 152 and a second conductive fixing pin 154 , and the negative electrode contact block 152 is fixed in the second groove 124 of the first insulating positioning block 120 through the second conductive fixing pin 154 . Here, the conductive fixing pin with conductive function is used instead of the insulating fixing pin. In addition to fixing the positive and negative contact blocks on the first insulating positioning block, it can also play the role of fixing the power line and conducting electricity.
[0040] see again Figure 4 , in particular, the first conductive fixing pin 144 is a screw, and a first gasket 146 is also provided between the positive contact block 142 and the first conductive fixing pin 144; the second conductive fixing pin 154 is a screw, and the negative contact block 152 and the first A second spacer 156 is also disposed between the two conductive fixing pins 154 . After winding the power cord on the screw, put the washer on it and then screw the screw into the positive and negative contact blocks. Electricity. Gaskets are arranged between the positive and negative contact blocks and the conductive positioning pins, which effectively reduces the gap between the contact blocks and the positioning pins, resulting in a better fixing effect.
[0041] Please combine figure 2 , image 3 , Figure 5 As shown, the positive receiving group 240 includes a first telescopic piece 242, a first conductive contact piece 244, and a first spring tongue 246 arranged in sequence; one end of the first telescopic piece 242 abuts on the first conductive contact piece 244, and the other end Butt against the second insulating positioning block 220; the first elastic tongue 246 is covered with a first insulating post 246a, and the first insulating post 246a is also covered with a first positioning piece 246b, and one end of the first positioning piece 246b is abutted against the first insulating post 246a. The other end of a spring tongue 246 abuts against the first conductive contact piece 244 .
[0042] The negative receiving group 250 includes a second telescopic piece 252, a second conductive contact piece 254, and a second elastic tongue 256 arranged in sequence; one end of the second telescopic piece 252 abuts against the second conductive contact piece 254, and the other end abuts against the second conductive contact piece 254. On the second insulating positioning block 220; the second elastic tongue 256 is covered with a second insulating column 256a, and the second insulating column 256a is also covered with a second positioning piece 256b, and one end of the second positioning piece 256b abuts against the second elastic tongue 256 , and the other end abuts against the second conductive contact piece 254 .
[0043] In order to make the locating member play a better positioning effect, a first spring tongue groove 246c is opened on the first spring tongue 246, and a second spring tongue groove 256c is opened on the second spring tongue 256. 246b and one end of the second positioning member 256b are actually respectively abutted in the first spring tongue groove 246c and the second spring tongue groove 256c. Also, in order to increase the strength of the insulating column, the first insulating pin 266 is used to insulate the first spring tongue groove. The column 246a and the second insulating column 256a are connected in series. The positioning piece, the conductive contact piece and the elastic tongue of the above positive and negative receiving groups can all conduct electricity, and one end of the conductive contact piece is connected to the power line 260. The pole receiving group and the power cord are passed to the device to be charged. Here, with the help of the resilience of the telescopic element itself, the elastic tongue can always stay in a suitable position, ensuring good contact effect between the elastic tongue and the positive and negative contact blocks.
[0044] See Figure 5 , in particular, the first telescopic member 242 and the second telescopic member 252 are springs.
[0045] The first locating piece 246b and the second locating piece 256b are locating springs whose cross-section is in the shape of a "Q". Good positioning effect.
[0046] see again Figure 5 In particular, the cross-sections of the first elastic tongue 246 and the second elastic tongue 256 are crescent-shaped, and the design of this structure is conducive to the expansion and contraction of the elastic tongues when opening and closing the door.
[0047] The cross-sections of the first conductive contact piece 244 and the second conductive contact piece 254 are in the shape of a "U", and the telescopic piece is packed into the recessed position of the conductive contact piece, which can better limit the direction of the telescopic movement of the flexible piece, and obtain a more ideal The expansion and contraction effect, but also increases the contact area of ​​the conductive contact piece, which is convenient for connecting the power line.
[0048] like figure 1 As shown, an intelligent door lock 20 includes the above-mentioned automatic charging device 10, and also includes a door frame 30, a door body 40, and a lock body 50. The power transmission part 100 and the power receiving part 200 are respectively installed on the door frame 30 and the door body 40. The lock body 50 has a rechargeable battery 52 connected to the power receiving part 200 . When the smart door lock 20 is in the closed state, the power transmission part 100 and the power reception part 200 are connected at this time, and the power is transmitted to the In the rechargeable battery 52, the purpose of automatic charging is realized. This charging method is simple and does not need to add redundant steps, and the conversion rate of charging electric energy is high.
