[0020] In the above structure, the first shell 1 and the second shell 2 are two independent bodies. The AC plug 10 on the first shell 1 can be plugged into a 220V AC socket. The second shell 2 has a battery 20 and a charging and discharging mainboard 21, so it can be used as a mobile power supply. When the battery 20 is low on power, the second docking plate 22 can be docked with the first docking plate 11 to electrically connect the probe assembly 13 and the contact assembly 23. The AC-DC conversion circuit board 12 can charge the battery 20 through the charging and discharging mainboard 21, and based on the mutual attraction relationship between the first magnet assembly 14 and the second magnet assembly 24, the first shell 1 and the second shell 2 can be reliably combined, and the charging process does not rely on wires, so it is more convenient to use in combination.
[0021] As a preferred embodiment, the AC plug 10 is a flip-up plug, that is, the AC plug 10 can be stored and hidden in a slot on the first housing 1 .
[0022] In order to realize the wireless charging function, in this embodiment, see Figure 4 The second housing 2 is provided with a wireless charging seat 26, and a wireless charger is provided in the wireless charging seat 26, and the wireless charger is electrically connected to the charging and discharging mainboard 21. For example, the wireless charger can be used to charge a smart watch.
[0023] In this embodiment, two flip plugs 25 are provided on the second housing 2, and the interface models of the two flip plugs 25 are different. The two flip plugs 25 can be matched with different models of electronic products, such as mobile phones, etc.
[0024] To achieve reliable magnetic attraction, the first magnet assembly 14 includes two first magnets 140, the probe assembly 13 is located between the two first magnets 140, the second magnet assembly 24 includes two second magnets 240, the contact assembly 23 is located between the two second magnets 240, the first magnet 140 and the second magnet 240 correspond one to one and have opposite magnetic poles.
[0025] Among them, this embodiment preferably arranges two first magnets 140 on both sides of the probe assembly 13, and simultaneously arranges two second magnets 240 on both sides of the contact assembly 23, so that the magnetic attraction between the second docking plate 22 and the first docking plate 11 is evenly distributed, ensuring that the two are reliably connected.
[0026] Furthermore, the two first magnets 140 have the same magnetic poles on a side facing outside the first docking plate 11 , and the two second magnets 240 have the same magnetic poles on a side facing outside the second docking plate 22 .
[0027] Based on the above magnetic pole distribution, in this embodiment, the second docking plate 22 and the first docking plate 11 are not restricted in the docking direction, and even if the second housing 2 is rotated 180° along the horizontal axis, the probe and the contact can still be correctly connected. To achieve this function, the polarity of the probe and the contact can be set as follows:
[0028] The probe assembly 13 includes four probes arranged in sequence laterally, the two probes in the middle are electrically connected to one pole of the output end of the AC-DC conversion circuit board 12, and the probes at both ends are electrically connected to the other pole of the output end of the AC-DC conversion circuit board 12;
[0029] The contact assembly 23 includes four contacts arranged in sequence laterally, and the contacts correspond to the probes one by one. The two contacts in the middle are electrically connected to one pole of the input end of the charge and discharge mainboard 21, and the contacts at both ends are electrically connected to the other pole of the input end of the charge and discharge mainboard 21.
[0030] However, in actual applications, the first and second magnets may not be arranged according to the above-mentioned magnetic poles. In another embodiment of the utility model, it can also be arranged as follows: the two first magnets 140 have different magnetic poles on the side outside the first docking plate 11, and the two second magnets 240 have different magnetic poles on the side outside the second docking plate 22.
[0031] In practical applications of the present invention, wires can also be used to charge electronic devices. For example, the first shell 1 can be provided with a first wired socket 15 electrically connected to the output end of the AC-DC conversion circuit board 12, and the second shell 2 can be provided with a second wired socket 27 electrically connected to the output end of the charging and discharging mainboard 21.
[0032] In this embodiment, in order to make the first and second shells more tightly and reliably connected, see Figure 2 The first shell 1 is provided with a recessed portion 17, the first docking plate 11 is arranged in the recessed portion 17, the second shell 2 includes a protruding portion 28, the second docking plate 22 is arranged on the protruding portion 28, and the protruding portion 28 can be plugged and matched with the recessed portion 17.
[0033] The above description is only a preferred embodiment of the present invention and is not intended to limit the present invention. Any modifications, equivalent substitutions or improvements made within the technical scope of the present invention should be included in the scope of protection of the present invention.
