Subsequently, the dust-proof plate 320 is pressed again until the positioning end 351 of the elastic positioning element 350 abuts against the second guiding inclined surface 372 of the second positioning block 370, the dust-proof plate 320 continues to be pressed, due to the stopping and guiding effects of the second guiding inclined surface 372, the elastic positioning element 350 also elastically deforms towards the rebound avoiding channel 3100, when the positioning end 351 completely disengages from the second guiding inclined surface 372, the elastic positioning element 350 is clamped into the second positioning groove 371 under the elastic restoring force of the return spring 340, as shown in fig. 6, the dust-proof plate 320 shields the opening 110 and the charging port 200, and the dust-proof effect is achieved.
Because if dust guard 320 and connecting piece 330 fixed connection, then when being pressed and kick-back to the position that makes charging mouth 200 expose, for the convenient charging mouth 200 that utilizes to expose charges, dust guard 320 is great because of the rebound distance this moment, keeps away from charging mouth 200 more distant place to conveniently charge mouthful 200 external charging wire, and dust guard 320 rebound distance must increase whole dust keeper's volume greatly, is unfavorable for present increasingly miniaturized, the electronic product that becomes more meticulous to use. To avoid this problem, in the present embodiment, the dust-proof plate 320 is rotatably connected to the connecting member 330, as shown in fig. 1 and fig. 5 to fig. 12, a protruding connecting portion 321 is formed on a side surface of the dust-proof plate 320 opposite to the opening, a T-shaped groove 322 is formed on the protruding connecting portion 321, one end of the connecting member 330 is embedded into the T-shaped groove 322 and rotatably connected to the protruding connecting portion 321, the end of the connecting member 330 is referred to as a connecting end 331 thereof, in the present embodiment, the connecting end 331 is elastically deformable and is extruded into the T-shaped groove 322 through elastic deformation, and a guiding inclined surface 332 and a deformation avoiding notch 333 which are beneficial for the connecting member to be embedded into the T-shaped groove 322 are formed on the connecting end 331.
Rotate through dust guard 320 and connecting piece 330 and be connected, only need press the distance of kick-backing to set up to can break away from the opening with it, this moment only need rotate dust guard 320 then to keep away from charging mouthful 200 as shown in fig. 1 the state can, dust guard 320 can not hinder the operation of charging mouthful promptly, and the distance of kick-backing of dust guard 320 need not too big simultaneously to be favorable to reducing the volume of port dust keeper 300, and then reduce the volume of electron.
Preferably, the dust guard 320 is adapted to fit into the opening 110 so that it fits into the opening 110 when it closes the opening 110, flush with the bottom surface of the housing, and blends into the appearance of the housing, enhancing aesthetics, as shown in fig. 2.
Further, the mounting seat 310 of the present embodiment is an integrally formed structure with the housing, that is, it is a part of the housing, so as to facilitate product assembly; alternatively, the mounting base 310 may be a separate component that is secured to the housing. First locating piece 360, second locating piece 370 and backstop 380 can directly be fashioned on mount pad 310 or on the casing, because first locating piece 360, second locating piece 370 and backstop 380 are located the guide slot 311, if the guide slot 311 space is little, it is big to mould first locating piece 360, second locating piece 370 and backstop 380 degree of difficulty in little space guide slot 311, for solving this problem, set up a support 390 alone in this embodiment, first locating piece 360, second locating piece 370 and backstop 380 shaping are on support 390, then insert support 390 and establish in guide slot 311, then fix through gluing or screw.
As shown in fig. 6, in the present embodiment, the inclination direction of the first return guiding slope 381 is opposite to the inclination direction of the second guiding slope 372, and the lowest point of the first return guiding slope 381 and the lowest point of the second guiding slope 372 are located at two sides of the sliding direction (as shown by the vertical arrow in fig. 6) of the elastic positioning element 350; at this time, the rebound avoidance passage 3100 includes a return avoidance passage 3110 and a process avoidance passage 3120, the return avoidance passage is located on the side of the lowest point of the first return guide slope 381, and the process avoidance passage is located on the side of the lowest point of the second guide slope 372.
Since the inclination direction of the first return guiding slope 381 is opposite to the inclination direction of the second guiding slope 372, and meanwhile the lowest point of the first return guiding slope 381 and the lowest point of the second guiding slope 372 are located at two sides of the sliding direction of the elastic positioning member 350, the dust-proof plate 320 is pressed upward from the state shown in fig. 6 until the positioning end 351 of the elastic positioning member 350 abuts against the first return guiding slope 381 of the stopper 380, the dust-proof plate 320 is continuously pressed, at this time, the elastic positioning member 350 is elastically deformed as shown in fig. 7, the rebound path is as shown by arrows in fig. 6 and 7, i.e., the left return bypass passage 3110 is taken, when the positioning end 351 is completely separated from the first return guiding slope 381, the elastic positioning member 350 is positioned in the first positioning groove 361, as shown in fig. 8, at this time, the dust-proof plate 320 is popped downward to be away from the opening 110 and the charging port 200, so that the charging port 200 is exposed.

The elastic deformation direction of the elastic positioning element 350 is opposite to the elastic deformation direction of the elastic positioning element 350 in the process of closing the opening 110 when the dust-proof plate 320 is pressed to open the opening 110, that is, the elastic positioning element 350 swings and deforms in two opposite directions, so that the problem that the elastic positioning element 350 deforms elastically in one direction all the time to cause excessive deformation and is difficult to return to the original state can be avoided.
Further, as shown in fig. 6 and 7, the second positioning block 370 further has a second return guide inclined surface 373 facing the first positioning groove 361, and an inclined direction of the second return guide inclined surface 373 is opposite to an inclined direction of the second guide inclined surface 372, so that the second return guide inclined surface 373 guides the positioning end 351 of the elastic positioning member 350 to enter the first positioning groove 361 more smoothly on a path where the elastic positioning member 350 rebounds from the left return escape passage into the first positioning groove 361. In this embodiment, the highest point of the second return guiding inclined surface 373 intersects with the highest point of the second guiding inclined surface 372 to form a point, which forms the tip of the second positioning block 370.
Of course, the inclination direction of the first return guiding slope 381 may also be the same as the inclination direction of the second guiding slope 372, and in this case, the lowest point of the first return guiding slope 381, the lowest point of the second guiding slope 372, and the rebound escape channel 3100 should be located on the same side of the sliding direction of the elastic positioning member 350. In this embodiment, the elastic positioning element 350 can also elastically deform and resiliently snap into the first positioning groove 361 or the second positioning groove 371 under the guiding and stopping effects of the first return guiding inclined surface 381 or the second guiding inclined surface 372, but the elastic deformation of the elastic positioning element 350 always faces the same direction, which easily causes the elastic positioning element 350 to deform excessively in one direction, and the elastic positioning element 350 in this embodiment should be made of a material with better elastic performance.
As shown in fig. 6 to 9, the first positioning groove 361 is defined by two oppositely disposed and oppositely inclined sides of the first positioning block 360, and similarly, the second positioning groove 371 is defined by two oppositely disposed and oppositely inclined sides of the second positioning block 370, that is, the first positioning groove 361 and the second positioning groove 371 are both in a pointed shape, and the inclined sides thereof can play a good role in guiding, so that the positioning end 351 of the elastic positioning element 350 can smoothly enter or leave the first positioning groove 361 or the second positioning groove 371.
Furthermore, the positioning end 351 of the elastic positioning element 350 is hooked and hung in the second positioning groove 371 or the first positioning groove 361, which is also beneficial to the positioning end 351 to smoothly enter or leave the first positioning groove 361 or the second positioning groove 371.
In this embodiment, the elastic positioning element 350 is an elastic steel wire extending along the sliding direction, and one end of the elastic positioning element is fixedly connected to the connecting element 330, which is referred to as a fixed end 352, and in this embodiment, the fixed end 352 and the connecting element 330 are wound around and fixed on the connecting element 330. As shown in fig. 12, the fixing end 352 of the elastic positioning member 350 is bent into a U-shape, two adjacent side surfaces of the connecting member 330 are respectively formed with a slot 334 and a positioning hole 335, one side of the U-shaped fixing end 352 is embedded into the slot 334, and the end of the other opposite side is embedded into the positioning hole 335, so that the fixing end 352 is wound and fixed on the connecting member 330.
