Detailed Description

So that the manner in which the above recited objects, features and advantages of the present invention can be understood in detail, a more particular description of the utility model, briefly summarized above, may be had by reference to the embodiments thereof which are illustrated in the appended drawings. In addition, the embodiments and features of the embodiments of the present application may be combined with each other without conflict.

In the following description, numerous specific details are set forth to provide a thorough understanding of the present invention, and the described embodiments are merely a subset of the embodiments of the present invention, rather than a complete embodiment. All other embodiments, which can be obtained by a person skilled in the art without any inventive step based on the embodiments of the present invention, are within the scope of the present invention.

Unless defined otherwise, all technical and scientific terms used herein have the same meaning as commonly understood by one of ordinary skill in the art to which this invention belongs. The terminology used herein in the description of the utility model is for the purpose of describing particular embodiments only and is not intended to be limiting of the utility model.

Referring to fig. 1, the present invention provides a protective case 100, which can be mounted on an electronic device such as a mobile phone to prevent dust from entering the electronic device. In the embodiment of the present application, the case 100 is mainly used for a mobile phone. That is, in the present embodiment, the protective case 100 is a mobile phone protective case. The protective case 100 at least includes a frame 200. The frame 200 is rectangular and includes at least a middle layer 20 and an inner layer 30. The middle layer 20 is disposed outside the inner layer 30 and spaced apart from the inner layer 30.

It is understood that the protective case 100 may further include a back portion (not shown), and the rim 200 is fixedly coupled to a peripheral edge of the back portion. Thus, the frame 200 and the back together form an accommodating space for accommodating the mobile phone, and the edge of the mobile phone is abutted against the inner layer 30, thereby effectively protecting the mobile phone.

The inner layer 30 is provided with at least one inner layer through hole, and the middle layer 20 is also provided with a middle layer through hole at a corresponding position. For example, the inner layer 30 is provided with a first inner layer through hole 31, and the middle layer 20 is provided with a first middle layer through hole 21 corresponding to the first inner layer through hole 31. The protective case 100 further includes a slider 50. The sliding member 50 is disposed between the middle layer 20 and the inner layer 30, and is used for driving the middle layer 20 to slide relative to the inner layer 30. The middle layer 20 can be engaged by the sliding member 50 such that the first middle layer through hole 21 is close to or far from the first inner layer through hole 31.

Specifically, after the first middle layer through hole 21 is far away from the first inner layer through hole 31, the first inner layer through hole 31 is shielded by a portion of the middle layer 20 not provided with the middle layer through hole. When the first middle layer through hole 21 is gradually close to the first inner layer through hole 31, the first middle layer through hole 21 slides to a corresponding position of the first inner layer through hole 31, so that the first inner layer through hole 31 is exposed through the first middle layer through hole 21.

In one embodiment, the slider 50 is a pulley. The pulley is disposed between the middle layer 20 and the inner layer 30 for better sliding of the middle layer 20 relative to the inner layer 30. The protective case 100 also includes a toggle 24. The toggle member 24 is disposed on the middle layer 20. The toggle member 24 may be a protrusion, for example, and the toggle member 24 is used to toggle the middle layer 20 to slide along the sliding direction of the sliding member 50.

In one embodiment, the frame 200 further includes an outer layer 10. The outer layer 10 is disposed on a side of the middle layer 20 away from the inner layer 30, and is spaced apart from the inner layer 30 to form a vent groove 40. The middle layer 20 and the slider 50 are both located within the vent slot 40. The outer layer 10 is provided with a first outer layer through hole 11 and an opening 14, and the first outer layer through hole 11 is disposed corresponding to the first inner layer through hole 31 and the first middle layer through hole 21, so that the first inner layer through hole 31 and/or the first middle layer through hole 21 can be exposed through the first outer layer through hole 11. The toggle member 24 is disposed in the opening 14, and the toggle member 24 can perform a linear reciprocating motion in the opening 14 along a length direction of the opening 14, so as to drive the middle layer 20 to rotate along a sliding direction of the sliding member 50, and further to enable the first middle layer through hole 21 to be close to or far from the first inner layer through hole 31.

It can be understood that the position where the first inner layer through hole 31 (or the first middle layer through hole 21 or the first outer layer through hole 11) is opened corresponds to a charging port of a mobile phone. So, through rotating middle level 20, can make middle level 20 shields first inlayer through-hole 31, and then make and work as when the cell-phone need not insert and establish the charging wire, effectively shelter from first inlayer through-hole 31, and then prevent to have dust to get into. Similarly, when a charging wire needs to be inserted, the middle layer 20 can be rotated so that the first inner layer through hole 31 is not shielded by the middle layer 20, i.e. the first inner layer through hole 31 is exposed through the first middle layer through hole 21 and the first outer layer through hole 11.

It should be understood that, referring to fig. 2 together, fig. 2 is another schematic view of the protective shell 100. Obviously, when the toggle member 24 rotates the middle layer 20, so that the first middle layer through hole 21 gradually approaches the first inner layer through hole 31 until the position shown in fig. 1 (the position of the first inner layer through hole 31) is reached, the first inner layer through hole 31 is exposed through the first middle layer through hole 21. At this time, the toggle member 24 is located at one end of the opening 14, the first inner layer through hole 31 is exposed, and the protective shell 100 is in the first state. When the toggle member 24 drives the middle layer 20 to rotate, so that the first middle layer through hole 21 gradually gets away from the first inner layer through hole 31 until the first middle layer through hole 21 rotates to the position shown in fig. 2 (the position avoiding the first inner layer through hole 31), the first inner layer through hole 31 is completely shielded by the part of the middle layer 20 not provided with the middle layer through hole. At this time, the toggle member 24 is located at the other end of the opening 14, and the protective case 100 is in the second state. That is, the protective case 100 includes a first state and a second state. The first state and the second state are switched by sliding of the middle layer 20. For example, in the first state, the toggle member 24 is located at one end of the opening 14, and the first inner layer through hole 31 is exposed. In the second state, the toggle member 24 is located at the other end of the opening 14, and the first inner layer through hole 31 is blocked by the middle layer 20.

It can be understood that, by arranging the outer layer 10 and the middle layer 20 at an interval and arranging the middle layer 20 and the inner layer 30 at an interval, a gap is left in the frame 200, and the protective case 100 can play a better role in buffering when the mobile phone falls down.

It is understood that the frame 200 may have a square shape, and the sliding members 50 (pulleys) include four ones, which are respectively disposed at four corners of the frame 200. Four corners of the outer layer 10 are respectively provided with a protruding part 15. The protrusion 15 can make the mobile phone protection case 100 better protect the mobile phone when the mobile phone is dropped, and can increase the space of four corners in the frame 200 to better place the sliding member 50.

In a specific embodiment, the outer layer 10 has a second outer layer through hole 12, the inner layer 30 has a second inner layer through hole 32, and the second outer layer through hole 12 and the second inner layer through hole 32 are correspondingly disposed. The middle layer 20 is provided with a second middle layer through hole 22 corresponding to the second outer layer through hole 12 and the second inner layer through hole 32. When the middle layer 20 slides relative to the inner layer, the second inner layer through hole 32 is always exposed through the second middle layer through hole 22 and the second outer layer through hole 12.

It is understood that, in the embodiment of the present application, the second outer layer through hole 12, the second inner layer through hole 32 and the second middle layer through hole 22 may correspond to a volume key of a mobile phone. That is, the mobile phone can be accommodated in the protective case 100, and the volume key thereof can be exposed from the second inner layer through hole 32, the second middle layer through hole 22, and the second outer layer through hole 12.

It will be appreciated that in the case of a mobile phone having a separate volume key, since dust is less likely to enter from the location of the volume key, the location of the second outer layer through hole 12 (or the location of the second inner layer through hole 32 or the second middle layer through hole 22) is generally exposed to expose the volume key of the mobile phone. Thus, the volume key of the mobile phone can be normally used without being affected by the image of the protective case 100.

Referring to fig. 1 and 2, it can be understood that, in one embodiment, the toggle member 24 and the second middle layer through hole 22 are located on the same side of the frame 200. The second outer layer via 12 and the opening 14 are located on the same side of the frame 200. The toggle member 24 can reciprocate linearly up and down along the length of the opening 14. As shown in fig. 1, when the toggle member 24 moves to a first position (e.g., near one end of the second outer layer through hole 12), the first inner layer through hole 31 is exposed through the first middle layer through hole 21 and the first outer layer through hole 11. As shown in fig. 2, when the toggle member 24 moves to a second position (e.g., an end away from the second outer layer through hole 12), the first inner layer through hole 31 is blocked by the middle layer 20.

It is understood that the opening position of the at least one inner layer through hole (or the at least one middle layer through hole) and the opening position of the opening 14 (or the setting position of the toggle member 24) may not be on the same side of the frame 200. It is only necessary to ensure that the at least one inner layer through hole and the at least one middle layer through hole are located at the same side of the frame 200 and are disposed correspondingly, and the toggle member 24 and the opening 14 are located at the same side of the frame 200 and are disposed correspondingly.

Referring to fig. 1 and 2, it can be understood that the at least one inner layer through hole may further include a third inner layer through hole 33, the at least one middle layer through hole may further include the third middle layer through hole 23, and a third outer layer through hole 13 is further disposed on the outer layer 10. The third inner layer through hole 33, the third middle layer through hole 23 and the third outer layer through hole 13 are all correspondingly arranged. The third middle layer through hole 23 can be rotated to shield or expose the third inner layer through hole 33, and the specific principle is similar to that of the first middle layer through hole 21 and the first inner layer through hole 31, and is not described herein again. The opening position of the third inner layer through hole 33 (or the third middle layer through hole 23 or the third outer layer through hole 13) may correspond to an earphone hole of a mobile phone, for example. Therefore, the middle layer 20 can be rotated to shield the third inner layer through hole 33 from the middle layer 20, so that when the mobile phone does not need to be inserted with an earphone, the third inner layer through hole 33 is effectively shielded, and dust is prevented from entering the mobile phone. Similarly, when the earphone is required to be inserted, the middle layer 20 may be rotated so that the third inner layer through hole 33 is not shielded by the middle layer 20, that is, the third inner layer through hole 33 may be exposed through the third middle layer through hole 23 and the third outer layer through hole 13.

Referring to fig. 3 and 4, the length of the second inner layer through hole 32 is a first length a, the length of the second middle layer through hole 22 is a second length b, the maximum distance that the toggle element 24 can move is a third length c, and the second length b is equal to the first length a + the third length c. Obviously, by limiting the length of the second middle layer through hole 22, it can be ensured that the middle layer 20 is not jammed by the volume key of the mobile phone during the sliding process of the toggle piece 24 in the process of the linear reciprocating motion.

Referring to fig. 4 and 5, the length of the opening 14 is a fourth length e, the maximum distance that the toggle element 24 can move is a third length c, the width of the toggle element 24 in the moving direction is a fifth length d, and the fourth length e is equal to the third length c + the fifth length d. Obviously, by limiting the length of the opening 14, it is ensured that the toggle member 24 can linearly reciprocate in a suitable range (the protective case 100 can achieve the first state and the second state).

It is understood that, since the middle layer 20 is disposed at the periphery of the inner layer 30 and spaced apart from the inner layer 30, the outer layer 10 is disposed at a side of the middle layer 20 away from the inner layer 30 and the outer layer 10 is spaced apart from the middle layer 20. The overall length of the inner layer 30 < the overall length of the middle layer 20 < the overall length of the outer layer 10.

According to the utility model, the middle layer through hole and the inner layer through hole are respectively formed on the middle layer 20 and the inner layer 30, and the inner layer through hole can be shielded by the middle layer 20 in the sliding process of the middle layer 20 through the double-layer design that the middle layer 20 slides relative to the inner layer 30, so that dust can be prevented from entering the interior of the mobile phone.

Finally, it should be noted that the above embodiments are only intended to illustrate the technical solutions of the present invention and not to limit the same, and although the present invention has been described in detail with reference to the preferred embodiments, it should be understood by those skilled in the art that modifications or equivalent substitutions may be made to the technical solutions of the present invention without departing from the spirit and scope of the technical solutions of the present invention.
