[0079] The technical solutions in the embodiments of the present application will be described clearly and completely below with reference to the drawings in the embodiments of the present application. Obviously, the described embodiments are only some of the embodiments of the present application, but not all the embodiments of the present application.

When an element is referred to as being "connected" to another element, it can be directly connected to the other element or there can be intervening elements. When an element is referred to as being "disposed" on another element, it can be directly on the other element or there can be intervening elements. The terms "vertical", "horizontal", "left", "right", and similar expressions used herein are for purposes of description only.

[0081] Unless otherwise defined, 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 application belongs. The terminology used in the description of the application herein is for the purpose of describing particular embodiments only and is not intended to be limiting of the application. As used herein, the singular forms "a", "an" and "the" are intended to include the plural forms as well, unless the context clearly indicates otherwise.

[0082] Some embodiments of the present application are described in detail. The following embodiments and features of the embodiments can be combined with each other in the case of no conflict.

[0083] Referring to Figures 1 to 3 , the present embodiment provides an electronic device 200, comprising a housing 201 and a shielding device 100.

[0084] The housing 201 comprises a bottom wall 202 and a side wall 203 connected to the edge of the bottom wall 202 and enclosing a receiving cavity Q with the bottom wall 202. The side wall 203 is provided with a through hole K1 (see Figure 3 ), which penetrates the inner surface and the outer surface of the side wall 203 to communicate the receiving cavity Q and the external environment of the housing 201.

[0085] Referring to Figure 2 and Figure 3 , the shielding device 100 is installed in the housing 201, i.e. the shielding device 100 is arranged in the receiving cavity Q. The shielding device 100 comprises a driving member 10, a functional assembly 20 and a shielding member 30. The functional assembly 20 is drivingly connected to the driving member 10 and can be driven by the driving member 10 to move towards the through hole K1. The shielding member 30 is movably connected to the functional assembly 20. During the movement of the driving member 10 driving the functional assembly 20 to move the shielding member 30 towards the through hole K1, the shielding member 30 moves relative to the functional assembly 20 until the through hole K1 is shielded. During the movement of the driving member 10 driving the functional assembly 20 to move away from the through hole K1, the shielding member 30 is driven by the functional assembly 20 to open the through hole K1.

[0086] According to the shielding device 100 of the present embodiment, the driving member 10 can move the functional assembly 20, and the functional assembly 20 drives the shielding member 30 to move and shield the through hole K1, thereby improving the shielding reliability of the through hole K1. Compared with the known shielding structure, the possibility of foreign matter on the outside of the housing 201 entering the inside of the housing 201 from the gap between the housing 201 and the shielding member 30 can be reduced, and in the case of water, the waterproof effect can be further improved. In addition, since the functional assembly 20 is used as a transmission structure, compared with the known shielding structure, the volume of the shielding device 100 can be greatly reduced, the installation space requirement of the driving member 10 and the shielding member 30 can be reduced, and the shielding device 100 can be directly applied to the existing electronic device products, thereby reducing the modification cost.

[0087] In the present embodiment, the functional assembly 20 is a loudspeaker assembly, and the through hole K1 is a loudspeaker hole. In other embodiments, the functional assembly 20 can be a USB interface, a power interface or other types of hardware interface.

[0088] In the present embodiment, referring to Figure 2The driving member 10 is configured to drive the functional assembly 20 to move along the first direction X.

[0089] In some embodiments, referring to Figures 2 to 4 The shielding device 100 further comprises a pushing member 40. One end of the pushing member 40 is in transmission connection with the driving member 10 and can rotate about the rotation axis L (see Figure 2 ) under the driving of the driving member 10. The rotation axis L is perpendicular to or obliquely intersects with the displacement direction of the functional assembly 20 (i.e. the first direction X). The other end of the pushing member 40 abuts against the functional assembly 20. During the movement of the driving member 10 driving the pushing member 40 to rotate about the rotation axis L towards the through hole K1, the pushing member 40 can push the functional assembly 20 to move towards the through hole K1. Through the arrangement of the pushing member 40, the driving member 10 and the functional assembly 20 can be connected without the connection structure. When the shielding device 100 is small in size, the driving member 10 can still drive the functional assembly 20 to move, thereby reducing the processing cost of the shielding device 100 and improving the versatility thereof. The pushing member 40 can be configured as a push block. One end of the push block is connected with the output shaft of the driving member 10, and the other end of the push block is suspended to abut against the functional assembly 20.

[0090] In other embodiments, the driving member 10 can be configured as a linear driving structure, such as a linear motor, so that the output shaft of the linear motor can directly abut against the functional assembly 20. Therefore, there are various ways to realize the movement of the driving member 10 driving the functional assembly 20, which are not limited in the present embodiment.

[0091] In some embodiments, referring to Figures 3 to 5 The shielding device 100 further comprises a resetting member 50. The resetting member 50 is connected with the functional assembly 20 and the housing 201, and is configured to drive the functional assembly 20 to reset to an initial position away from the through hole K1. The initial position is a position where the functional assembly 20 is away from the through hole K1 and the shielding member 30 opens the through hole K1. In this way, when the driving member 10 is retracted in a direction away from the through hole K1, the resetting member 50 can drive the functional assembly 20 to move in a direction away from the through hole K1. Thus, the driving member 10 only needs to be in contact with the functional assembly 20, and the two do not need to be connected through the connection structure. When the electronic device 200 is small in size, the processing difficulty of the shielding device 100 can be reduced, and the movement reliability of the functional assembly 20 can be ensured at the same time.

[0092] In some embodiments, referring to Figure 3 The number of the resetting members 50 is two. The two resetting members 50 are arranged at intervals along the first direction X. The housing 201 further comprises a boss portion 206 which protrudes from the bottom wall 202 towards the surface of the functional assembly 20. The resetting member 50 can be configured as an elastic element. One end of the two resetting members 50 is connected with the functional assembly 20, and the other end is elastically supported on the boss portion 206.

[0093] In some embodiments, referring to Figure 2 and Figure 3 , the bottom wall 202 of the shell 201 is provided with a first guide portion 205. The functional assembly 20 is provided with a second guide portion 23 towards the bottom surface of the bottom wall 202, the first guide portion 205 cooperates with the second guide portion 23 and is used to guide the movement of the functional assembly 20 in the first direction X. Thus, the movement stability of the functional assembly 20 is improved, the movement reliability of the shielding member 30 relative to the functional assembly 20 is improved, and the shielding member 30 can be accurately moved to the position of shielding the through hole K1 under the driving of the functional assembly 20.

[0094] In some embodiments, referring to Figure 3 , the number of the second guide portions 23 is two, the two second guide portions 23 are arranged in the second direction Y and define a guide groove C2. The number of the first guide portions 205 is two, the two first guide portions 205 are arranged in the second direction Y, the two first guide portions 205 extend in the first direction X, and the two guide strips 24 are respectively attached to the groove side surfaces P3 of the guide groove C2 arranged opposite in the second direction Y.

[0095] In some embodiments, referring to Figure 3 , the two second guide portions 23 are respectively connected to the two sides of the bottom surface of the main body portion 21 in the first direction X. The two second guide portions 23 extend in the first direction X and define the guide groove C2 with the main body portion 21. The guide groove C2 penetrates through the two side surfaces of the main body portion 21 arranged opposite in the first direction X. The two first guide portions 205 are respectively attached to the two second guide portions 23. One end of the reset member 50 is connected to the side of the main body portion 21 in the first direction X away from the shielding member 30, and the other end of the reset member 50 abuts against the boss portion 206.

[0096] In some embodiments, referring to Figure 3 , the boss portion 206 extends in the first direction X. The two first guide portions 205 are respectively connected to the two ends of the boss portion 206 in the first direction X. Thus, the boss portion 206 and the first guide portions 205 can be integrally machined and formed, reducing the processing difficulty of the shell 201.

[0097] In some embodiments, referring to Figure 2 and Figure 3The shielding device 100 further comprises a detection assembly 60 configured to detect the humidity inside the shell 201, the detection assembly 60 being electrically connected with the driving member 10, the driving member 10 being configured to drive the functional assembly 20 to move close to the through hole K1 when the humidity detected by the detection assembly 60 is within a preset range. Specifically, the preset range can be set as a range greater than a preset value. In this way, when water outside the shell 201 enters the shell 201 through the through hole K1, the detection assembly 60 detects that the humidity enters the preset range, and the driving member 10 can drive the functional assembly 20 to move, so that the shielding member 30 closes the through hole K1, thereby achieving the waterproof effect.

[0098] In some embodiments, referring to Figure 2 and Figure 3 , the detection assembly 60 comprises a humidity sensor 61 and a transmission line 62. The humidity sensor 61 is arranged on the side of the bottom wall 202 close to the through hole K1, and is used to detect the humidity. The transmission line 62 is electrically connected with the driving member 10 and the humidity sensor 61, and is used to transmit a detection signal to the driving member 10.

[0099] In some embodiments, referring to Figure 3 , the shielding device 100 further comprises a dustproof member 70 arranged on the inner surface of the shell 201 and covering the through hole K1. In this way, the dustproof effect of the accommodation cavity Q is improved. The dustproof member 70 can be specifically configured as a dustproof net.

[0100] In some embodiments, referring to Figure 4 and Figure 5 , the shielding member 30 comprises a rotating part 31 and a shielding part 32. The rotating part 31 is rotatably connected with the functional assembly 20, and the shielding part 32 is fixedly connected with the rotating part 31. During the process of driving the functional assembly 20 to move close to the through hole K1 by the driving member 10, the rotating part 31 abuts against the shell 201 and rotates relative to the functional assembly 20 under the limiting of the shell 201, until the shielding part 32 shields the through hole K1.

[0101] In some embodiments, referring to Figure 4 and Figure 5 , the number of the rotating parts 31 is two, the two rotating parts 31 are respectively connected with the two ends of the length direction of the shielding part 32, and the number of the limiting parts 204 is two, the two limiting parts 204 are respectively arranged corresponding to the two rotating parts 31. In this way, the stability of the shielding member 30 during the movement process can be improved, so as to ensure that the shielding member 30 moves to the position where the shielding part 32 shields the through hole K1.

[0102] Specifically, the rotating part 31 has a first end 311 and a second end 312, and the hinge point P9 between the rotating part 31 and the functional assembly 20 is located between the first end 311 and the second end 312. The side of the functional assembly 20 is provided with a pivot 22, the rotating part 31 is provided with a pivot hole K2, the pivot 22 is accommodated in the pivot hole K2, and the pivot hole K2 is configured as the hinge point P9 between the rotating part 31 and the functional assembly 20. The shielding piece 30 has a first state of being spaced apart from the through hole K1 and a second state of shielding the through hole K1. In some embodiments, the pivot hole K2 penetrates the rotating part 31 along the second direction Y.

[0103] In some embodiments, referring to Figure 6 and Figure 7 , the shell 201 further comprises a limiting part 204. The limiting part 204 is connected to one end of the side wall 203 away from the bottom wall 202. The limiting part 204 has a guide surface P1 facing the inside of the accommodation cavity Q, and the guide surface P1 is inclined in a direction away from the bottom wall 202 in the first direction X away from the direction of the through hole K1. When the shielding piece 30 is in the first state, the driving piece 10 drives the functional assembly 20 to drive the shielding piece 30 to move close to the limiting part 204 to abut against the guide surface P1. In the process of the functional assembly 20 continuing to drive the shielding piece 30 to move, the first end 311 moves in the third direction Z away from the bottom wall 202 and in the first direction X away from the direction of the through hole K1 under the limitation of the guide surface P1, thereby driving the rotating part 31 to rotate relative to the functional assembly 20 until the shielding part 32 is clamped between the functional assembly 20 and the shell 201, and the through hole K1 is shielded.

[0104] In some embodiments, referring to Figure 6 and Figure 7 , the rotating part 31 has an arc surface P6 located at the second end 312 and arranged close to the bottom wall 202, so that the arc surface P6 does not collide with the bottom wall 202 in the process of the first end 311 abutting against the guide surface P1 and driving the rotating part 31 to rotate relative to the functional assembly 20, thereby ensuring the rotation reliability of the rotating part 31.

[0105] In some embodiments, referring to Figure 6 and Figure 7 , in the process of the shielding piece 30 moving away from the through hole K1 from the second state, the shielding piece 30 rotates to the first state relative to the functional assembly 20 under the action of its own weight. In this way, the shielding piece 30 of the present embodiment and the shell 201 can be connected without a component transmission, and the function of resetting the shielding piece 30 is still achieved, thereby improving the installation convenience of the shielding device 100. In other embodiments, a reset structure such as a spring element or a linkage mechanism can be additionally arranged between the shielding piece 30 and the shell 201 to reset the shielding piece 30 in the process of the functional assembly 20 moving away from the shell 201.

[0106] In some embodiments, referring to Figure 6 and Figure 7 , the limiting portion 204 further has a first limiting surface P2 facing the bottom wall 202 along the third direction Z. The rotating portion 31 has a second limiting surface P7 extending to the first end 311. The second limiting surface P7 is spaced apart from the through hole K1 along the first direction X at a position where the rotating portion 31 is away from the through hole K1. After the rotating portion 31 rotates to abut against the side wall 203, the second limiting surface P7 abuts against the first limiting surface P2, so as to limit the rotating portion 31 from continuing to rotate, thereby achieving the fool-proof effect.

[0107] In some embodiments, referring to Figure 6 and Figure 7 , the bottom surface of the functional assembly 20 is provided with a concave-structured avoiding groove C1 on the side close to the through hole K1. The avoiding groove C1 penetrates to the side surface of the functional assembly 20 facing the through hole K1 along the first direction X. The shielding member 30 is movably in and out of the avoiding groove C1 under the driving of the functional assembly 20. When the functional assembly 20 is away from the through hole K1, the shielding member 30 is accommodated in the avoiding groove C1.

[0108] In this way, when the functional assembly 20 is away from the through hole K1, the shielding member 30 does not occupy the space between the functional assembly 20 and the through hole K1, thereby ensuring the normal operation of the through hole K1. For example, when the through hole K1 is a plug-in hole, an external plug can be smoothly inserted into the shell 201 through the through hole K1 without being blocked by the shielding member 30. When the through hole K1 is a sound emitting hole, the sound generated by the loudspeaker assembly (i.e., the functional assembly 20) can be smoothly transmitted to the external environment through the through hole K1 without being blocked by the shielding member 30.

[0109] Referring to Figure 8 , the avoiding groove C1 is enclosed between the end surface of the second guiding portion 23 close to the end of the through hole K1 along the first direction X and the bottom surface of the functional assembly 20. In this way, the avoiding groove C1 can be formed by additionally providing the second guiding portion 23 on the bottom of the functional assembly 20, thereby improving the convenience of modification without the need to provide the avoiding groove C1 on the existing loudspeaker assembly.

[0110] In some embodiments, referring to Figure 9 and Figure 10 , the shielding portion 32 is provided with an inclined surface P5. In the case where the shielding portion 32 is accommodated in the avoiding groove C1, the inclined surface P5 is located on the side of the shielding portion 32 away from the bottom wall 202 along the third direction Z. In the direction away from the through hole K1, the distance between the inclined surface P5 and the bottom wall 202 along the third direction Z gradually decreases, so as to facilitate the shielding portion 32 to smoothly enter the avoiding groove C1. Meanwhile, in the case where the shielding portion 32 shields the through hole K1, the surface of the shielding portion 32 opposite to the inclined surface P5 is used to shield the through hole K1, so as to ensure that the inclined surface P5 does not affect the shielding effect of the shielding portion 32 on the through hole K1.

[0111] In some embodiments, referring to Figure 10 When the shielding member 30 is in the second state, the functional assembly 20 abuts against the shielding portion 32 to the side wall 203 of the housing 201 and shields the through hole K1. In this way, by the functional assembly 20 applying a force to the shielding portion 32, the contact tightness between the shielding portion 32 and the side wall 203 can be improved, thereby improving the shielding reliability of the through hole K1.

[0112] In some embodiments, referring to Figure 10 and Figure 11 The inner surface of the side wall 203 is provided with a concave formed accommodation groove C3 near the bottom wall 202. The length of the accommodation groove C3 along the second direction Y is greater than the length of the shielding member 30 along the second direction Y. The through hole K1 penetrates the groove side surface P3 of the accommodation groove C3 and the outer surface of the side wall 203. The accommodation groove C3 has a groove top surface P4, which is formed offset from the top surface of the side wall 203 towards the bottom wall 202. The limiting portion 204 is protrudingly arranged from the groove top surface P4 towards the bottom wall 202, and the guide surface P1 is the surface of the limiting portion 204 along the first direction X towards the driving member 10. In this way, the movement of the shielding member 30 can be carried out in the accommodation groove C3, so as not to occupy the space of the accommodation cavity Q inside the side wall 203, thereby improving the space utilization rate in the housing 201.

[0113] In some embodiments, referring to Figure 11 The number of the through holes K1 is multiple, and the multiple through holes K1 are distributed at intervals along the second direction Y. The length direction of the shielding portion 32 is parallel to the second direction Y, and the shielding portion 32 is a full-length structure, that is, the shielding portion 32 extends beyond both ends of the multiple through holes K1 in the second direction Y, so as to ensure that the shielding portion 32 simultaneously shields the multiple through holes K1 and guarantees the shielding effect.

[0114] The above embodiments are only used to illustrate the technical solutions of the present application and not to limit the present application. Although the present application has been described in detail with reference to the above preferred embodiments, those skilled in the art should understand that the technical solutions of the present application can be modified or replaced by equivalents without departing from the spirit and scope of the technical solutions of the present application.
