Detailed Description
The small portable quick-charging charger provided by the embodiment comprises a charging head 1 and charging wires, and referring to fig. 1 to 3, a circuit board 3 is installed in the charging head 1, a plurality of USB interfaces 11 for connecting the charging wires are arranged on the charging head 1, a fool-proof groove 12 is formed in any one of the USB interfaces 11, and a fool-proof boss matched with the fool-proof groove 12 is arranged on a connector of the charging wire; a plurality of elastic support columns 15 used for supporting the circuit board 3 are uniformly distributed in the charging head 1, threaded holes are formed in the end portions of the elastic support columns 15, and through holes corresponding to the threaded holes are formed in the circuit board 3; a protective shell 2 is further slidably sleeved on the outer side of the charging head 1, a plurality of elastic positioning pieces 21 are uniformly arranged on one group of symmetrical inner side surfaces of the protective shell 2 along the length direction of the protective shell, and positioning holes 13 clamped with the elastic positioning pieces 21 are formed in the outer side surface of the charging head 1; the other symmetrical inner side surfaces of the protective shell 2 are respectively provided with positioning bosses 22 along the length direction, and the outer side surface of the charging head 1 is provided with positioning grooves 14 which are in one-to-one correspondence with the positioning bosses 22.
It should be noted that, the structure of current charger has been improved to this embodiment, the unsettled frame of main control board in the head that charges 1 is on elastomeric support post 15, when guaranteeing installation stability, improve its buffer protection performance, a protective housing 2 is still installed to the first outside of charging 1, can effectively protect the joint of charging wire, prevent that it from receiving external force striking to damage, and protective housing 2 installs through the elasticity joint between elastic positioning piece 21 and locating hole 13, can change its mounted position fast, adapt to different service environment.
When circuit board 3 installs, correspond via hole on the circuit board 3 with the screw hole on the elastic support column 15, then get screw 4 and pass via hole and screw hole in proper order to lock circuit board 3 on elastic support column 15, in this embodiment, elastic support column 15 sets up to the gluey integrated into one piece structure of dominant force, and this elastic support column 15 can support with the whole injection moulding of head 1 that charges, also can be with the help of outside mounting, like the bolt. The rubber and the like are fixed in the charging head, the friction rubber is wear-resistant and has certain elasticity, so that the circuit board 3 can be well supported, and meanwhile, the circuit board 3 can be elastically buffered and protected by means of elastic deformation of the rubber; the number of the elastic support columns 15 is four, and the elastic support columns 15 are arranged in a matrix mode, so that the installation stress of the circuit board 3 is uniform, and the installation stability of the circuit board is guaranteed.
When the protective housing 2 is installed, correspond first 1 tip of charging with 2 ports of protective housing and insert, it should be explained, 2 medial surface sizes of protective housing and the first 1 lateral surface size adaptation that charges, elastic positioning element 21 possesses the flexible tip of elasticity protrusion protective housing 2 medial surface, therefore, the in-process of pegging graft between protective housing 2 and the first 1 that charges, elastic positioning element 21 tip can receive the extrusion between first 1 lateral surface that charges and each locating hole 13 port, and compressed to 2 medial surface parallel and level with the protective housing, thereby make things convenient for grafting between protective housing 2 and the first 1 that charges, after both install target in place, one-to-one between elastic positioning element 21 and the locating hole 13, at this moment, elastic positioning element 21 loses the extrusion force that receives, stretch out in locating hole 13 under self elastic restoring force effect, with locating hole 13 joint, restriction relative movement between them. When the relative position between protective housing 2 and the first 1 that charges needs to be adjusted, only need promote protective housing 2 hard, make the power of exerting oneself be greater than the joint power between first 1 and the protective housing 2 that charges, can compress elastic positioning element 21 tip once more, thereby contact the joint power between elastic positioning element 21 and the locating hole 13, make first 1 and the protective housing 2 that charges take place relative movement, in this embodiment, arbitrary side elastic positioning element 21 quantity sets up to six, consequently, it can have six relative positions to charge between first 1 and the protective housing 2. When the charging wire was inserted on charging head 1, for the joint of protection charging wire, can be with stretching a target distance between charging head 1 and the protective housing 2, honor the joint of charging wire and aim at the protective housing 2 inboard, protect, simultaneously, when needs carry charging head 1 and charging wire, can draw the relative position between protective housing 2 and the charging head 1 to the biggest, put the charging wire at protective housing 2 inboard, conveniently carry.
Further, elastic positioning element 21 sets up to spring plunger, and spring plunger is the standard component among the prior art, and elastic effect is good, and is stand wear and tear, easy to assemble, in this embodiment, it counterpoints still to be equipped with positioning groove 14 and location boss 22 between head 1 and the protective housing 2 to charge, makes things convenient for installation between them.
Further, prevent slow-witted recess 12 with positioning groove 14's cross section all sets up to ARC structure, and the structural design of preventing slow-witted recess 12, when can avoiding the USB joint of charging wire and being connected between the USB interface 11 of the first 1 that charges, can't find the position accurately, avoids inserting the problem of turning over, can carry out the plug fast.
Further, the number of USB interface 11 sets up to three, and three USB interface 11 evenly arrange in charge 1 terminal surface of head, can provide the installation of a plurality of charging wires, charge for a plurality of equipment.
The above is only the preferred embodiment of the present invention, and not the scope of the present invention, all the equivalent structures or equivalent flow changes made by the contents of the specification and the drawings or the direct or indirect application in other related technical fields are included in the patent protection scope of the present invention.
