The terms of directions used in the present invention, such as "up", "down", "front", "back", "left", "right", "side", etc., refer only to the directions of the attached drawings. Accordingly, directional terminology is used to describe and understand the invention and is not limiting of the invention.
In the following embodiments, like parts are denoted by like reference numerals in different drawings.
As shown in fig. 2 to 6, the case structure 100 with waterproof function of the present invention includes a case 200 and a waterproof unit 300. The case 200 has an opening 210 and a receiving space communicating with the opening 210, the opening 210 being for inserting the card 400 into the receiving space. The waterproof unit 300 is disposed adjacent to the opening 210. Specifically, the waterproof unit 300 includes an elastic roller 310 and an elastic member connected to the elastic roller 310. When the card 400 is not inserted into the opening 210, the elastic roller 310 is abutted against the opening 210 by the elastic member to form a seal. When the card 400 is inserted from the opening 210, the card 400 pushes the elastic roller 310 to deform in communication with the elastic member to form a yielding, and the card 400 is inserted from the opening 210 into the accommodating space to the target position.
The waterproof unit 300 of the housing structure 100 with waterproof function of the present invention includes an elastic roller 310 and an elastic member. When the card 400 is not inserted into the opening 210 of the housing 200, the elastic member provides an elastic force to the elastic roller 310, so that the elastic roller 310 abuts against the housing near the opening 210 to close the opening 210, thereby preventing external moisture from entering the housing from the opening 210 when the card 400 is not inserted into the opening 210. When the card 400 is inserted from the opening 210, a user can push the elastic roller 310 and the elastic member by the force applied to the card 400 so that the elastic roller 310 is not abutted against the shell near the opening 210 any more, thereby releasing the closure of the opening 210, facilitating the insertion of the card 400 from the opening 210, and the card 400 is contacted with the elastic roller in the insertion process, and the elastic roller 310 rotates relative to the card 400 when the card 400 pushes the elastic roller 310 to move in the process of pushing the card 400 to the target position, so that friction is reduced and damage to the surface of the card 400 is avoided; meanwhile, the elastic roller 310 and the card 400 are always kept in a mutually pushed state by the elastic member, so that the opening 210 always maintains tightness. That is, in the process that the card 400 is not inserted or inserted into the housing structure 100 with the waterproof function, moisture in the external environment cannot invade from the opening 210 toward the inside of the accommodating space, so as to affect the circuit in the accommodating space inside the housing, thereby improving the waterproof performance.
In this embodiment, the elastic member includes a first elastic member 320 and a second elastic member 360. The first elastic member 320 is disposed at a first end of the elastic roller 310, and the second elastic member 360 is disposed at a second end of the elastic roller 310, where the first end of the elastic roller 310 is opposite to the second end of the elastic roller 310.
As shown in fig. 3, when the card 400 is inserted into the opening 210, the card 400 pushes the elastic roller 310 and the first elastic member 320 and the second elastic member 360, so that the elastic roller 310 is linked to deform and displace the first elastic member 320 and the second elastic member 360, thereby releasing the opening 210 from being closed. Specifically, when the card 400 is inserted into the opening 210 along the first direction X, the card 400 provides a pushing force towards the first direction X to deform the first elastic member 320 and the second elastic member 360, so that the elastic roller 310 is displaced from (at least a portion of) the first elastic member 320 and (at least a portion of) the second elastic member 360, and the elastic roller 310 is no longer in abutment with the housing near the opening 210 to release the closure of the opening 210, so as to facilitate the insertion of the card 400.
As shown in fig. 4 to 6, the waterproof unit 300 further includes a body 330, the body 330 is fixedly connected to the housing 200 and adjacent to the opening 210, and two ends 311, 312 of the elastic roller 310 are movably connected to the body 300. Further, the body 330 is provided with a first track 331, two ends 311 and 312 of the elastic roller 310 are slidably disposed on the first track 331, when the card 400 is inserted into the opening 210, the card 400 pushes against the elastic roller 310, the first elastic member 320 and the second elastic member 360, the card 400 pushes against the elastic roller 310, the elastic roller 310 drives one ends of the first elastic member 320 and the second elastic member 360 to deform, so that the elastic roller 310 slides along a first path on the first track 331 to release the closure of the opening 210, and the card 400 is inserted into the accommodating space; the elastic roller 310 rotates relative to the card 400 when the elastic roller 310 is pushed against the card 400, and at this time, the first elastic member 320 and the second elastic member 360 exert elastic force to press the elastic roller 310 against the card 400, so as to maintain the tightness between the elastic roller 310 and the card 400. (further describing the process of the roller 310 interlocking with the deformation of the elastic member 320).
In this embodiment, the body 330 and the roller 310 are substantially parallel, and the opening 210 is, for example, a straight slot, and the extending direction of the straight slot is substantially parallel to the roller 310.
As shown in fig. 6, the first rail 331 has a chute structure, and the first path is, for example, moving upward along the chute.
In this embodiment, the first path forms an included angle with the first direction X, for example, 45 ° to 60 °, so that when the card 400 pushes against the elastic roller 310 and the first elastic member 320 and the second elastic member 360 to deform the first elastic member 320 and the second elastic member 360, the elastic roller 310 displaces in the second direction Y in addition to the first direction X, so that the card 400 passes under the elastic roller 310 and enters the target position inside the housing 200, and the second direction Y is not parallel to the first direction X, for example, the second direction Y is perpendicular to the first direction X.
In actual operation, when the card 400 is removed from the opening 210, the card 400 moves along the third direction X ', and the third direction X' is opposite to the first direction X, in this process, the first elastic member 320 and the second elastic member 360 gradually recover to deform to push the elastic roller 310 to slide along the second path on the first track 331 so as to gradually recover to abut against the housing near the opening 210, thereby recovering the closing of the opening 210, and the first path is opposite to the second path, so that after the card 400 leaves the opening 210, the opening 210 is closed again to avoid the erosion of external moisture and protect the electronic components in the housing interior.
In other words, when the card 400 is pulled out from the housing structure 100, the elastic member connected to the elastic roller 310 gradually resets to provide an elastic force to enable the elastic roller 310 to slide on the first track 331 of the body 330 along the second path to reset to abut against the housing near the opening 210, so as to restore the sealing of the opening 210, and the first path is opposite to the second path, so that after the card 400 leaves the opening 210, the opening 210 is sealed again to avoid erosion of external moisture and protect the electronic components in the housing space.
