[specific embodiment]
For object of the present invention, feature and advantage can more be become apparent, below in conjunction with accompanying drawing, the specific embodiment of the present invention is described in detail.
Fig. 2 is that in an embodiment, flashlight is by the schematic diagram after tail cover of flashlight STRUCTURE DECOMPOSITION, and Fig. 3 is the exploded view of tail cover of flashlight structure embodiment illustrated in fig. 2.Flashlight comprises light emitting source (not shown), stack shell 200 and the tail cover of flashlight structure 100 that is connected in stack shell afterbody 210.Tail cover of flashlight structure 100 comprises:
Tail-hood cylinder 130, the tubular structure that tail-hood cylinder 130 is both ends open, this tubular structure is double-layer structural, referring to Fig. 4, outer 132 are connected with one end of internal layer 134 connecting portion 133 by annular slice.Distance between skin 132 and internal layer 134 and the thickness of stack shell afterbody 210 match, and form for stack shell afterbody 210 and insert the annular groove that forms connection, and tail-hood cylinder 130 just can be fixed on stack shell afterbody 210 like this.
Button cap compressing tablet 120, button cap compressing tablet 120 is circular ring plate, and the outer surface of crown is provided with the shallow slot of accommodating button cap compressing tablet 120.The material that button cap compressing tablet 120 is hard, is sheet metal in the present embodiment, also can adopt in other embodiments other hard materials, such as hard plastic sheet etc.Because button cap 140 is more soft elastic materials, the feel when button cap compressing tablet 120 that hard is set can improve user's pressing keys cap 120, is easier to operation.
Charging plug connector 170, forms and is connected for the charging plug with inserting, to the battery charging in flashlight.The structure of charging plug connector 170 and adaptive plug match, and connected wire is not shown in the accompanying drawings.
Threaded fastener 110, crown, button cap compressing tablet 120 and charge port shell 150 offer the through hole coordinating with threaded fastener 110, and threaded fastener 110 is fixedly connected with crown, button cap compressing tablet 120 and charge port shell 150.Threaded fastener 110 is 4 screws in the present embodiment.Apparent, threaded fastener 110 and button cap compressing tablet 120 all can omit in other embodiments, and charge port shell 150 can be connected by other connected modes with button cap 140, and for example button cap 140 is closely linked on charge port shell 150.
Connector the first sealing gasket 162 and connector the second sealing gasket 164, connector the first sealing gasket 162 and connector the second sealing gasket 164 are tubular structures of both ends open, connector the first sealing gasket 162 is closely sheathed on one end of charging plug connector 170, connector the second sealing gasket 164 is closely sheathed on the other end of charging plug connector 170, and connector the first sealing gasket 162 and connector the second sealing gasket 164 is placed in the accommodating cavity of charge port shell 150 in the lump with charging plug connector 170.Connector the first sealing gasket 162 and connector the second sealing gasket 164 can play waterproof action, guarantee that the liquid entering from charge port 141 is unlikely to infilter the circuit of flashlight inside, battery part.Notice that charge port shell 150 should mate with the size of connector the first sealing gasket 162 towards the diameter of the opening of charge port 141, can pack into and be fixed in charge port shell 150.Same, connector the second sealing gasket 164 also should be able to pack in charge port shell 150.
Be provided with the circuit board 190 of switch 192, circuit board 190 is fixed on the stack shell afterbody of flashlight, be provided with the one side of switch 192 towards charging plug connector 170, support 180 is fixed on circuit board 190, and support 180 is connected with circuit board 190 by column provided thereon (not indicating in figure).
In other embodiments, also can omit support 180, button cap 140 directly contacts with circuit board 190.The life-span that support 180 can improve product with respect to the direct mode contacting with circuit board 190 of button cap 140 is set, because can produce the button cap 140 of deformation, directly contacts the damage that may cause circuit, components and parts on circuit board 190 when pressing with circuit board 190.And the mode coordinating with column on support 180 by perforate on circuit board 190 does not have this potential safety hazard.
In addition, when water resistance is not required, also can omit connector the first sealing gasket 162 and connector the second sealing gasket 164, or connector the first sealing gasket 162 is only set and connector the second sealing gasket 164 is not set.
For guaranteeing that charge port shell 150 has enough spaces to offer the through hole coordinating with threaded fastener 110, charge port shell 150 should be done greatlyr towards one end of button cap compressing tablet 120.
During user's pressing keys cap 140, the crown of button cap 140, to lower recess, drives charge port shell 150 and inner charging plug connector 170 (also having the first sealing gasket 162 and connector the second sealing gasket 164) thereof to move downward, thus touching switch 192.After letting go, button cap 140 deformation recovery under self elastic reaction drives charge port shell 150 grades to get back to original position simultaneously.
When tail cover of flashlight structure 100 is installed, can first support 180 be installed on circuit board 190, then connector the first sealing gasket 162 and connector the second sealing gasket 164 are sheathed on charging plug connector 170 fills in charge port shell 150 in the lump, then after button cap compressing tablet 120, button cap 140 and charge port shell 150 being fixed together by threaded fastener 110, stretch in support 180, finally tail-hood cylinder 130 is built to (stack shell afterbody 210 inserts in the annular groove of tail-hood cylinder 130), just completed the installation of tail cover of flashlight structure 100.
Above-mentioned tail cover of flashlight structure and flashlight, button cap takes full advantage of the area of tail-hood, and button cap size (lifting surface area) is large, is easy to carry out pressing operation.And this simple and reliable for structure, easy realization, easy for installation, with low cost.
The above embodiment has only expressed several embodiment of the present invention, and it describes comparatively concrete and detailed, but can not therefore be interpreted as the restriction to the scope of the claims of the present invention.It should be pointed out that for the person of ordinary skill of the art, without departing from the inventive concept of the premise, can also make some distortion and improvement, these all belong to protection scope of the present invention.Therefore, the protection domain of patent of the present invention should be as the criterion with claims.
