That is, in the second position, a part of the sliding member 83 may be located right in the recessed area 22, in some cases, a small part of the liquid may be attached to the sliding member 83 (the part of the sliding member 83 between the water blocking member and the front housing 1) after the liquid enters the charging stand from the sliding groove, and in the second position, the sliding member 83 is substantially closely connected to the bottom surface of the recessed area 22, so that the liquid on the sliding member 83 can directly flow into the waterproof groove 21 through the bottom surface.

At least a portion of the waterproof groove 21 near the front case 1 is a stepped groove wall, that is, the waterproof groove 21 includes a first groove 211 and a second groove 212, specifically, a bottom surface of the recessed region 22 is recessed inward to form the first groove 211, a bottom surface of the first groove 211 is recessed inward to form the second groove 212, an opening of the second groove 212 is smaller than an opening of the first groove 211, and the first groove 211 and the second groove 212 are coplanar with a wall surface far from the front case 1 and substantially flush with the stepped surface 253. The first mounting seat 2 can adopt an injection molding process, and the waterproof groove 21 is designed into a stepped groove wall, so that the drawing is convenient, and the first mounting seat 2 can be conveniently processed.

In addition, the front side of the first mounting seat 2 is provided with a mounting groove for accommodating the wireless charging assembly 6, the mounting groove and the waterproof groove 21 are substantially at the same position (in the up-down direction) of the first mounting seat 2, that is, the bottom surface of the first groove 211 and the side surface of the mounting groove can share the same wall structure, that is, the inner side surface of the wall structure constitutes the side surface of the mounting groove, and the outer side surface of the wall constitutes the bottom surface of the first groove 211; the front side surface of the second groove 212 and the bottom surface of the seating groove share the same structure, that is, the front side surface of the structure constitutes the bottom surface of the seating groove, and the rear side surface of the structure constitutes the front side surface of the second groove 212, so that the seating groove can be easily obtained by providing the first groove 211 and the second groove 212 even on the basis of forming the waterproof groove 21, thereby facilitating the installation of the wireless charging assembly 6.

Further, a diversion port 23 is arranged on the side wall of the lower side of the recessed area 22, and the diversion port 23 is communicated with the stepped surface 253, so that liquid in the waterproof tank 21 flows to the stepped surface 253 through the diversion port 23, and the liquid is ensured to flow to the air outlet 24 from the diversion structure 25. The flow guide 23 may be a chamfered cut as shown in fig. 3.

Further, in the embodiment where the waterproof groove 21 includes a stepped groove wall, the diversion port 23 is aligned with the second groove 212 in the left-right direction, so that the liquid in the second groove 212 can flow out of the diversion port 23 conveniently, and the liquid in the first groove 211 can converge and flow out to the diversion port 23, thereby avoiding the liquid from flowing out from the area of the non-diversion port 23 on the side wall of the lower side of the first groove 211, and ensuring that the liquid can flow to the air outlet 24 along the diversion structure 25.

The water baffle 85 has a gap between two opposite side walls in the width direction of the sliding groove and the inner wall of the waterproof groove 21. That is, a gap is left between the upper side wall of the water deflector 85 and the upper side surface of the waterproof groove 21, and a gap is left between the lower side wall of the water deflector 85 and the lower side surface of the waterproof groove 21, so that the water deflector 85 can slide in the left-right direction without being caught by the waterproof groove 21.

Of course, the water baffle is in sliding fit between the two opposite side walls in the width direction of the sliding groove and the inner wall of the waterproof groove.

Referring to fig. 8 and 9, the edge of the sliding groove protrudes to one side of the first mounting seat 2 to form a convex ring 111; the water guard plates 85 are respectively provided with water guard edges 86 protruding from the edges on both sides in the width direction, and the water guard edges 86 are in sliding fit with the outer annular surface of the convex ring 111.

The edge of the sliding groove protrudes backwards to form a convex ring 111, the sliding groove is formed in the convex ring 111, the water baffle 85 is respectively provided with a water baffle edge 86 in a forward protruding mode in the vertical direction, the water baffle edge 86 on the upper side is positioned on the upper side of the convex ring 111, the water baffle edge 86 on the lower side is positioned on the lower side of the convex ring 111, so that the water baffle 85 can completely cover the sliding groove in the vertical direction, when liquid enters the charging bracket from the sliding groove, the liquid can only flow onto the water baffle 85 under the limitation of the convex ring 111, and therefore the liquid can only flow onto the water baffle 85; in addition, even if the impact force of the liquid is large, the liquid is splashed by the water guard 85, and the splashed liquid is only bounced to the inner wall of the convex ring 111 and finally flows from the inner wall of the convex ring 111 to the water guard 85.

The water stop edge 86 is in sliding contact with the outer annular surface of the convex ring 111, and can limit the sliding direction of the water stop piece, so that the clamping mechanism can only slide along the left-right direction.

In embodiments where there is only one water guard 86 on the water guard 85, the water guard 86 is located on the underside of the male ring 111.

For the water blocking edge 86, the width dimension of the water blocking edge 86 in the front-back direction becomes smaller in the direction towards the first mounting seat 2, that is, for the first water blocking piece, the width of the water blocking edge 86 on the first water blocking piece becomes smaller from left to right, so that the part of the water blocking edge 86 with the larger width is far away from the first waterproof groove, the part of the water blocking edge 86 with the larger width is preferentially aligned with the exposed sliding groove, the drainage effect on liquid is improved, and the water blocking edge 86 with the smaller width is close to the first waterproof groove, so that the interference between the water blocking edge 86 and the waterproof groove 21 is avoided. Similarly, for the second water stop, the width of the water stop edge 86 thereon decreases from right to left. Specifically, the water blocking edge 86 may have a stepped structure as shown in fig. 8, and when the water blocking member slides to a certain position, the stepped surface of the stepped structure abuts against the outer side wall of the first mounting seat, and the sliding of the water blocking member can be limited.

That is, in the second position (the mobile phone is not clamped between the two clamping heads), the first clamping head can completely cover the first sliding groove 11, the second clamping head can completely cover the second sliding groove 12, and the waterproof jacket 84 can also relatively seal the sliding grooves, so that external liquid cannot enter the charging holder from the sliding grooves (the first sliding groove 11 and the second sliding groove 12).

For the first clamping mechanism 81, the sliding part 83 is taken as a boundary, and the size of the first water baffle plate at the right side part of the sliding part 83 is larger than that of the first water baffle plate at the left side part of the sliding part 83; similarly, for the second clamping mechanism 82, the size of the second water blocking plate of the left side portion of the sliding member 83 is larger than that of the second sliding plate of the right side portion, in the second position, the right side portion of the first sliding groove 11 is in the exposed state, the left side portion of the second sliding groove 12 is in the exposed state, the first water blocking plate is substantially located on the right side of the corresponding sliding member 83, so that the first water blocking plate can correspond to the exposed portion of the first sliding groove 11, and the second water blocking plate is substantially located on the left side of the corresponding sliding member 83, so that the first water blocking plate can correspond to the exposed portion of the second sliding groove 12, and thus the waterproof effect can be achieved.
