In practical operation, when external liquid is splashed onto the mobile device, the cover 200 and the housing assembly 100 can be isolated from each other to prevent the liquid from directly entering the mobile device from the first opening 101. In general, since the liquid guide tank 103 is shielded by the upper lid 200 covering the first opening 101, the external liquid does not flow into the liquid guide tank 103 directly. It can be understood that, due to a certain gap existing between the upper cover 200 and the housing assembly 100, when a part of the liquid flows in from the gap at the connection between the housing assembly 100 and the upper cover 200, that is, a part of the liquid flows from the edge of the first opening 101 of the housing assembly 100 to the inside of the housing assembly 100, the liquid guiding groove 103 at the edge of the first opening 101 of the housing assembly 100 receives and guides the liquid, so as to prevent the liquid from entering the inside of the housing assembly 100 from the first opening 101, and prevent the penetrated liquid from affecting the normal operation of the electronic components inside the mobile device. Wherein, the liquid can be water, oil, beverage, etc.

Specifically, in the embodiment shown in fig. 1, 2, 3 and 4, the housing assembly 100 includes a middle housing 110 and a front housing 120 connected to the middle housing 110, and the middle housing 110 and the front housing 120 enclose to form the first opening 101. The liquid guiding groove 103 includes a first liquid guiding groove 111 and a second liquid guiding groove 121, the middle housing 110 forms the first liquid guiding groove 111 at the edge of the first opening 101, the first liquid guiding groove 111 is substantially U-shaped, and the front housing 120 forms the second liquid guiding groove 121 at the edge of the first opening 101. Upper cover 200 is close to one side of casing subassembly 100 is equipped with the spacing protruding muscle 210 that is used for with first liquid guide groove 111 joint, and upper cover 200 stretches into first liquid guide groove 111 through spacing protruding muscle 210 in order to with the spacing cooperation of casing subassembly 100. On one hand, the limiting convex rib 210 can be in limiting fit with the first liquid guide groove 111, so that the connection between the shell assembly 100 and the upper cover 200 is more reliable; on the other hand, the limiting rib 210 can also play a certain sealing role to prevent the liquid that has penetrated into the housing assembly 100 from further flowing to a position outside the first liquid guiding groove 111.

In an embodiment, as shown in fig. 2, 3 and 4, in some embodiments, the middle shell 110 is formed with a first limiting portion 113 protruding inward from the first opening 101, and the edge of the upper cover 200 adjacent to the middle shell 110 is formed with a first clamping portion 201; the front shell 120 is formed with a second limiting portion 124 protruding inward from the first opening 101, and a second engaging portion 202 is formed at the edge of the upper cover 200 adjacent to the front shell 120. When the upper cover 200 is covered on the middle shell 110 through the first opening 101, the first clamping portion 201 and the second clamping portion 202 of the upper cover 200 are respectively clamped and matched with the first limiting portion 113 and the second limiting portion 124 of the middle shell 110, and are further fixed with the middle shell 110.

Referring to fig. 4 and 6, in some embodiments, a waterproof strip 123 may be disposed in the second liquid guiding groove 121, the waterproof strip 123 extends along the length direction of the second liquid guiding groove 121 to form a strip shape, and the waterproof strip 123 is supported between the groove wall of the second liquid guiding groove 121 and the upper cover 200 to prevent water in the second liquid guiding groove 121 from flowing into the housing assembly 100. The sealing effect of the housing assembly 100 can be further improved by providing the flashing strips 123. The waterproof strip 123 may refer to a silica gel waterproof strip 123.

Referring to fig. 5 and 6, in some embodiments, the middle housing 110 is provided with a first dropping portion 112, a distance between the first dropping portion 112 and the support plate 130 is smaller than a distance between the first liquid guiding groove 111 and the support plate 130, and the first dropping portion 112 is communicated with a bottom of the first liquid guiding groove 111. The front shell 120 is provided with a second dripping part 122, the distance between the second dripping part 122 and the support plate 130 is smaller than the distance between the second liquid guiding groove 121 and the support plate 130, and the second dripping part 122 is communicated with the bottom of the second liquid guiding groove 121. When the mobile device is operating normally and the height of the top cover 200 in the direction of gravity is higher than that of the housing assembly 100, if liquid flows into the first liquid guiding groove 111 and the second liquid guiding groove 121 from the edge of the first opening 101, the liquid in the first liquid guiding groove 111 can automatically flow to and concentrate on the first dropping portion 112 under the action of gravity, and the liquid in the second liquid guiding groove 121 can automatically flow to and concentrate on the second dropping portion 122 under the action of gravity.
