Specific implementation mode

The utility model is described in detail in the following with reference to the drawings and specific embodiments.

Embodiment

The utility model is related to it is a kind of can semi-automatic handling USB charging units, including front housing 1, PCBA circuit boards 2, Release button 3, fixing buckle 5, sliding block 8, rear shell 10, screw 11 and magnet 12.Front housing 1 and rear shell 10 affixed, the PCBA by screw 11 Circuit board be set between front housing 1 and rear shell 10, sliding block 8, fixing buckle 5, release button 3 be set to front housing 1 on, one end of fixing buckle 5 with 3 connection of release button, the other end are connect with sliding block 8, and magnet 12 is set in front housing 1, for fixing front housing 1 and rear shell 10.

The head of front housing 1 be equipped be used for ejecting fixing buckle lock hole 103, with the release release aperture 101 that matches of button with And the holes USB 102；PCBA circuit boards 2 are equipped with charging socket end, and charging socket end is stretched out from the holes USB 102.The bottom of front housing 1 is set It is useful for the slide opening 104 of the sliding disengaging of sliding block 8 and places the magnet groove 105 of magnet.It is respectively equipped with and slides in 1 shell of front housing Sliding block card slot 18, fixed buckle card slot 14 and the release buckle card slot 15 and a latch plate that block 8, fixing buckle 5, release button 3 match 13。

Sliding block 8 is placed in 1 bottom end of front housing, and is slided and passed in and out from the bottom end of front housing 1 by slide opening 104.Sliding block 8 is equipped with sliding block Spring 9.The side of sliding block 8 is equipped with the groove 801 with contact inclined-plane 504.

Fixing buckle 5 includes sticking department 501, fixed part 502 and convergence part 503, size and the lock hole 103 of sticking department 501 Identical, fixed part 5 is equipped with the fixation button spring 6 that connect with rear shell 10, and convergence part 503 is rod-shaped, and convergence part 503 is equipped with the Two pin holes 505 run through convergence part 503 for the second pin 20；The side of convergence part 503 is equipped with to connect with latch plate 13 Fixing buckle side spring 7, the other side be equipped with contact inclined-plane 504, contact inclined-plane 504 shape match with card base 304.Locking The edge in hole 103 is equipped with to block the features of sticking department 501.

Release button 3 is blunt corner-shape structure, including button portion 301 and movable part 302, and one end of button portion is equipped with release button bullet Spring 4.The first pin hole 303 that movable part 302 is equipped with, movable part 302 pass through 19 rotary moveable of the first pin.

Sliding block spring 9, fixed button spring 6 and release button spring 4 are constantly in compressive state.

When using the USB charging units of the utility model, need to coordinate accessory (not drawn in the figure) with interior It uses, to being respectively equipped with the lock fit end to match with sticking department 301 and sliding block 8 and bottom abutting end on accessory.USB is filled When electric installation is inserted vertically into the bottom abutting end to accessory, bottom abutting end moves upwards the jack-up of sliding block 8, and sliding block 8 is close to solid Surely 5 are detained, the inclined-plane projection 506 on fixing buckle 5 is buckled on the groove 801 of sliding block 8, makes sliding block 8 that can not return to original position；Gu Determine button spring 6 elastic force push fixing buckle 5 rotate around the second pin 20, until sticking department 501 from lock hole 103 stretching, and The lock fit end to accessory is caught on, and the features in lock hole 103 can block 5 retraction interiors of products of fixing buckle, realizes USB Charging unit is packed into interior positive lock.Meanwhile fixing buckle side spring 7 can push fixing buckle 5 to carry out side displacement, until Close to the right side of release buckle card slot 15.Release button 3 is popped up because of the compression of release button spring 4 from release aperture 101.

To unlock, release button 3 is pulled, the card base 304 of release button 3 is pushed away by the contact inclined-plane 504 on fixing buckle 5 For dynamic fixing buckle 5 to left dislocation one end distance, fixing buckle 5 avoids the features on front housing 1 because of displacement；Continue to pull release button 3, Release button 3 is rotated because the effect of release button spring 4 presses against fixing buckle 5 around the second pin 20, is made in 5 retraction front housing 1 of fixing buckle Portion, departing from the lock fit end to accessory.Meanwhile sliding block 8 moves downward under the action of sliding block spring 9, due to reaction Power influences, and from the bottom abutting end abjection to accessory, so that USB charging units are integrally detached to accessory, realize USB and fills The automatic dismantling of electric installation in the car.

The front housing 1 for the USB charging units that the present embodiment uses and one end width of rear shell 10 is 83.2mm, other end width For 96.8mm, the length of front housing 1 and rear shell 10 is 100.9mm, and USB charging units are small, facilitates fixation, saves space.

Above description is only a specific implementation of the present invention, but the scope of protection of the utility model is not limited to In this, any staff for being familiar with the art within the technical scope disclosed by the utility model, can readily occur in various Equivalent modifications or substitutions, these modifications or substitutions should all contain shell and be within the protection scope of the utility model.Therefore, this practicality Novel protection domain should be subject to the protection scope in claims.
