Specific embodiment
The utility model proposes a kind of fixed structure of wrist-watch charging head.
Reference Fig. 1 and the axonometric chart that Fig. 3, Fig. 1 are charging head, Fig. 3 is the structure schematic diagram of wrist-watch.
As shown in figures 1 and 3, in this utility model embodiment, the fixed structure of the wrist-watch charging head includes：Some bullets
Pin 11, some sheet metals 21, the first Magnet 12 and the second Magnet 13, the first magnetic adsorption plate 22 and the second magnetic adsorption plate 23.Some bullet pins
11 are vertically arranged and are fixed on the end face of charging head 1.Some sheet metals 21 are engaged with each bullet pin 11, and are fixed on wrist-watch 2
The back side.When bullet pin 11 is contacted with sheet metal 21, pin 11 is played by the voltage output of charging head 1 to wrist-watch 2, to fill to wrist-watch 2
Electricity.In the present embodiment, the quantity for playing pin 11 is 4, and accordingly, the quantity of sheet metal 21 is also 4.First Magnet 12 and
Two Magnet 13 are oppositely arranged on the both sides of four bullet pins 11, and are fixed on the end face of charging head 1.First magnetic adsorption plate 22 and the second magnetic
Piece 23 is fixed on the back side of wrist-watch 2, and the first magnetic adsorption plate 22 is engaged with the first Magnet 12, the second magnetic adsorption plate 23 and the second Magnet
13 are engaged.First Magnet 12 magnetic pole relative with the first magnetic adsorption plate 22 is conversely, the second Magnet 13 is relative with the second magnetic adsorption plate 23
Magnetic pole conversely, the principle of opposite sex attraction for passing through Magnet, by charging head 1 back side of wrist-watch 2 is fixed on.The end face of charging head 1
Extend to the side of wrist-watch 2 along the back side of wrist-watch 2, form the adsorption plane 14 fitted with the side of wrist-watch 2.
The technical solution of the utility model by by the end face of charging head 1 along side from the back side of wrist-watch 2 to wrist-watch 2 extend,
Form the adsorption plane 14 fitted with the side of wrist-watch 2 so that the adsorption plane 14 of charging head 1 and the back side of wrist-watch 2 and side
Fit, it is to avoid play pin 11 and misplace with sheet metal 21, prevent the positive and negative electrode reversal connection of charging head 1 and wrist-watch 2, it is ensured that wrist-watch 2 fills
Electric safety.Magnetic charging head compared to existing technology, this utility model by the back side of the end face of charging head 1 and wrist-watch 2 and
The close fit of the side of wrist-watch 2, can effectively prevent user by the reversal connection of charging head 1, it is ensured that charge safety.
Further, the N poles of the first Magnet 12 towards wrist-watch 2 the back side, the back of the body of the S poles of the second Magnet 13 towards wrist-watch 2
Face.First Magnet 12 is reversed with the magnetic pole of the second Magnet 13, when charging head 1 it is anti-with the charging inlet at the back side of wrist-watch 2
Connect, now, the N poles of the first Magnet 12 can be extremely relative with the N of the second magnetic magnetic adsorption plate 23, and the S poles of the second Magnet 13 can be with the first magnetic
The S of suction piece 22 is extremely relative, by the effect of Magnet " same sex is repelled each other " so that charging head 1 mutually repels with wrist-watch 2 and cannot be connected,
Prompting user charging head 1 and the connection error of wrist-watch 2 are connect, so as to further prevent user the reversal connection of charging head 1.
Further, it is to improve the intensity that charging head 1 is connected with wrist-watch 2.The adsorption plane 14 of charging head 1 is along wrist-watch 2
Side to the front of wrist-watch 2 extends, and forms the back-off for clasping wrist-watch 2.Charging head 1 is allowd to snap onto handss by back-off
On table 2, increase the fastness of charging head 1 and the attachment structure of wrist-watch 2, prevent charging head 1 de- with wrist-watch 2 because of unexpected tearing
From.
Further, in order to ensure having stable voltage to transmit between charging head 1 and wrist-watch 2.As shown in Fig. 2 first
The height of the Magnet 13 of Magnet 12 and second is respectively less than or equal to the height of each bullet pin 11, that is, play the height portion of pin 11 more than the
The height of one Magnet 12 and the second Magnet 13.When charging head 1 is fixed at the charging inlet at the back side of wrist-watch 2, play pin 11 and pressed
Contracting, plays pin 11 and is connected to contact chip 21 by elastic force effect, it is ensured that the good contact of pin 11 and contact chip 21 is played, so as to ensure to fill
There is stable voltage to transmit between dateline 1 and wrist-watch 2.
Preferred embodiment of the present utility model is the foregoing is only, the scope of the claims of the present utility model is not thereby limited,
It is every under inventive concept of the present utility model, the equivalent structure made using this utility model description and accompanying drawing content is become
Change, or directly/be used in other related technical fields indirectly and be included in scope of patent protection of the present utility model.
