As shown in fig. 3-5, the present invention discloses an electronic device, which includes a housing, a lifting module 200 and a shielding member 300.

The housing includes a front case 100, and further, the housing may further include a rear case and a display module, the front case 100 and the rear case are connected to each other to form an outer case of the electronic device, and the display module may be mounted on the front case 100.

As shown in fig. 3, the front casing 100 is provided with a first sound guiding hole 110, and the first sound guiding hole 110 can communicate with the spaces inside and outside the front casing 100, so that sound can be better transmitted between the spaces. The first sound guide hole 110 may be formed by punching or the like after the front case 100 is molded, or may be integrally formed with the front case 100 during the formation of the front case 100. Accordingly, the shape and size of both the front case 100 and the first sound guide hole 110 may be determined according to actual requirements, and are not limited herein. Of course, the first sound guiding hole 110 may be generally disposed in an area without a display function on the housing, which may ensure the integrity of the area of the display module for displaying images in the housing, thereby improving the user experience of the product.

The lifting module 200 comprises a module housing 210 and an acoustic device 220, the module housing 210 is provided with a mounting cavity, the mounting cavity can provide a mounting base and a protection effect for mechanisms such as the acoustic device 220, the module housing 210 can be formed by plastic, metal or composite materials, and the specific shape and structure of the module housing can be determined according to actual requirements. The acoustic device 220 may be a receiver or a microphone, and since the acoustic device 220 is installed in the installation cavity, in order to ensure that the acoustic device 220 can transmit sound with the outside of the electronic device, as shown in fig. 3, the module housing 210 is further provided with a second sound guiding hole 213, and the second sound guiding hole 213 is communicated with the installation cavity.

Under the general condition, can also be provided with the camera subassembly in the lift module 200, through set up the camera subassembly on lift module 200 this kind of mode, can greatly promote whole electronic equipment's screen to account for than, and can protect the camera to a certain extent and receive destruction under non-operating condition. In view of the above and other reasons, during the design and use of the electronic device, as shown in fig. 3 and 4, the lifting module 200 generally has two states, namely, an extended state and a retracted state, and in detail, a power source such as a linear motor and a lifting cylinder may be configured in the electronic device to provide power for switching the lifting module 200 between the extended state and the retracted state. The extending state refers to a state that at least a part of the lifting module 200 extends out of the housing of the electronic device, and the functional device in the lifting module 200 in the extending state is located at the working position; the retracted state refers to the lifting module 200 being retracted into the housing of the electronic device, which can provide protection for the lifting module 200 in the retracted state. In order to ensure that the lifting module 200 can be switched between the extended state and the retracted state, an opening may be provided on the housing, so that the lifting module 200 can be extended out of the housing or retracted into the housing from the opening.

The shielding member 300 is located between the installation cavity and the front housing 100, specifically, the shielding member 300 can be located in a gap between the front housing 100 and the lifting module 200, the three are independent of each other, a part of the structure of the shielding member 300 is connected with the front housing 100, and the rest of the structure can be provided with a preset gap between the front housing 100 and the lifting module 200. Alternatively, the shutter 300 may be attached to a surface of the front case 100 or the lifting module 200. For another example, the shutter 300 may also be disposed inside the module housing 210 of the lift module 200. Of course, other positions between the mounting cavity and the front housing 100 can be used for disposing the shielding member 300, and the description is omitted here for brevity.

The shielding element 300 may be made of hard materials such as plastic or metal, or may be made of flexible materials such as rubber, silicon gel, or other high polymer materials, and the specific shape and size of the shielding element 300 may be determined according to actual requirements, which is not limited herein.

The shielding element 300 is connected to the front housing 100 to ensure that at least a portion of the shielding element 300 is stationary with respect to the front housing 100, and the shielding element 300 and the front housing 100 may be directly connected by clipping, inserting, or the like, or the shielding element 300 may be indirectly connected to the front housing 100 by means of screws or glue, even a connecting rod, or the like. As shown in fig. 3 and 4, the shielding member 300 is formed with a third sound guiding hole 321, and the second sound guiding hole 213 and the first sound guiding hole 110 can be communicated through the third sound guiding hole 321, so as to ensure that the acoustic device 220 located in the installation cavity can perform sound transmission with the outside of the electronic device under some conditions. Further, the size and shape of the third sound guiding hole 321 can be adaptively determined according to the respective sizes and shapes of the second sound guiding hole 213 and the first sound guiding hole 110, so as to achieve the purpose of improving the sound guiding performance.

As described above, the lifting module 200 can be switched between the extended state and the retracted state by a driving mechanism such as a linear motor during the operation of the electronic device. Since the shield 300 is connected to the front case 100, the lifting module 200 can move relative to the front case 100, and the lifting module 200 can also move relative to the shield 300. As shown in fig. 3, under the condition that the lifting module 200 is in the extended state, since the lifting module 200 generates a certain displacement relative to the front housing 100 and the shielding member 300, the third sound guiding hole 321 and the second sound guiding hole 213 are staggered, and the shielding member 300 blocks the third sound guiding hole 321, even if the lifting module 200 is in the extended state, that is, the lifting module 200 is exposed, since the shielding member 300 blocks the second sound guiding hole 213, external dust, water vapor and the like cannot enter the lifting module 200 from the second sound guiding hole 213, and then the acoustic device 220, even the electronic device, cannot be failed or damaged due to the foregoing reasons. As shown in fig. 4, when the lifting module 200 is in the retracted state, the third sound guiding hole 321 and the second sound guiding hole 213 are disposed opposite to each other, that is, the second sound guiding hole 213 disposed on the shielding member 300 can be used as a medium for communicating the second sound guiding hole 213 and the first sound guiding hole 110, so that the acoustic device 220 disposed in the mounting cavity can perform sound transmission with the outside of the electronic device.

In addition, in the process of switching the lifting module 200 between the extended state and the retracted state, the moving distance of the lifting module 200 relative to the front case 100 can be determined according to actual requirements; accordingly, the total length of the shield 300 can be determined according to practical requirements, and is not limited herein.

In order to make the shielding member 300 generate a better covering effect on the second sound guiding hole 213, as shown in fig. 5, the size of the shielding member 300 in multiple directions is increased, so that when the lifting module 200 is in the extended state, the projection of the second sound guiding hole 213 along the axial direction thereof is located in the projection of the shielding member 300 along the axial direction, which makes the shielding member 300 generate a shielding effect on the second sound guiding hole 213 more completely, so as to prevent external dust, water vapor and the like from entering the second sound guiding hole 213 from the edge of the shielding member 300 to the maximum extent.

Specifically, the size of the shutter 300 can be determined according to the size of the second sound guide hole 213, for example, the sizes of the second sound guide hole 213 in the first direction and the second direction are a and b, respectively, and the sizes of the shutter 300 in the first direction and the second direction are at least a and b. In order to further enhance the shielding effect of the shielding member 300 on the second sound guiding hole 213, during the design and production process, the dimension of the shielding member 300 in the first direction may be larger than a, and/or the dimension of the shielding member 300 in the second direction may be larger than b, so that the shielding member 300 can completely cover and shield the second sound guiding hole 213, thereby further preventing external dust and water vapor from entering the lifting module 200 through the second sound guiding hole 213. In addition, in the case where the sizes of the shutter 300 in the first direction and the second direction are larger than a and b, respectively, the size of the portion of the shutter 300 beyond the second sound guide hole 213 may be selected according to practical situations, and is not limited herein. Note that, the first direction and the second direction are both directions perpendicular to the axial direction of the second sound guide hole, and the axial direction of the second sound guide hole 213 may be a direction a in fig. 3.

Alternatively, the acoustic device 220 may be a receiver, and further, as shown in fig. 3 and 4, the receiver divides the installation cavity into a front cavity 211 and a rear cavity 212, and the front cavity 211 is communicated with the second sound guide hole 213, so as to ensure that the sound generated by the receiver can be transmitted to the outside of the electronic device by the gas in the front cavity 211; the rear cavity 212 is arranged, so that the sound quality of the whole receiver can be improved to a certain extent. Specifically, the shape of the whole installation cavity can be determined according to the space and the size in the lifting module 200, and accordingly, parameters such as the specific structure, the spatial layout, the volume ratio, and the like of the front cavity 211 and the rear cavity 212 formed by being separated by the receiver can also be flexibly determined according to the sound quality simulation process and the like, which are not limited herein.

Further, as shown in fig. 3 and 4, the shielding member 300 includes a positioning portion 310 and a blocking portion 320, and the positioning portion 310 is fixedly connected to the front shell 100, so as to ensure that the spatial position of the whole shielding member 300 is not substantially changed by the movement of the lifting module 200. The blocking part 320 is provided with a third sound guiding hole 321, and in the design and production process, the blocking part 320 can be located in the module housing 210, so that under the condition that the lifting module 200 is in the extending state, it is ensured that the blocking part 320 can extend into the third sound guiding hole 321 to generate a blocking effect on the third sound guiding hole 321. Meanwhile, the module housing 210 is further provided with a receiving cavity 214, the receiving cavity 214 is used for receiving at least a part of the blocking portion 320, as above, the positioning portion 310 is fixedly connected with the front housing 100, one end of the blocking portion 320 is connected with the positioning portion 310, and the other part of the blocking portion 320 can be in sliding fit with the receiving cavity 214, so that the blocking portion 320 does not extend out of the electronic device even if the size is larger.

When the electronic device of the present invention adopts the technical solution provided by the above embodiment, the size of the blocking portion 320 is no longer limited by the maximum displacement of the lifting module 200 and the specific parameters such as the position of the second sound guiding hole 213; in the case that the size of the blocking portion 320 is relatively long, even if the lifting module 200 moves to the maximum displacement position relative to the front case 100, it is basically ensured that no gap is generated between the blocking portion 320 and the second sound guide hole 213 in the moving direction of the lifting module 200. On the contrary, in order to ensure that the blocking portion 320 and the second sound guiding hole 213 are not shifted in the moving direction of the lifting module 200 and cannot be blocked, the blocking effect between the blocking portion 320 and the second sound guiding hole 213 can be ensured to be better by increasing the depth of the accommodating cavity 214 and the size of the blocking portion 320 in the moving direction.

Specifically, the opening of the receiving cavity 214 faces the blocking portion 320, so that in the process of switching the lifting module 200 from the extended state to the retracted state, the blocking portion 320 can extend into the receiving cavity 214 from the opening of the receiving cavity 214, and the receiving cavity 214 may be a linear structure. The positioning portion 310 and the blocking portion 320 may be formed by separate molding or integrated molding, and in the case of the integrated molding, the connection reliability between the positioning portion 310 and the blocking portion 320 may be improved to a certain extent; the shapes of the positioning portion 310 and the blocking portion 320 may be determined according to actual conditions, and the size of the blocking portion 320 may be determined according to parameters such as the size of the receiving cavity 214, the maximum displacement of the lifting module 200, and the position of the second sound guide hole 213.

A specific alternative embodiment is that, by designing the size of the blocking portion 320 in the moving direction of the lifting module 200, when the lifting module 200 is in the extended state, a part of the blocking portion 320 is still accommodated in the accommodating cavity 214, which basically ensures that the second sound guiding hole 213 can be completely blocked by the blocking portion 320, and the situation that the blocking portion 320 and the second sound guiding hole 213 are misaligned with each other does not occur.

Further, when the blocking portion 320 is disposed in the module housing 210 and the lifting module 200 is in the extended state, the blocking portion 320 may be disposed on a side of the second sound guiding hole 213 facing the mounting cavity or a side of the second sound guiding hole 213 departing from the mounting cavity, considering that the second sound guiding hole 213 has a predetermined dimension along the axial direction thereof. As shown in fig. 3 and 4, compared with the former solution, the latter solution has relatively low implementation difficulty in the design and production process, and does not have great adverse effects on the stability and reliability of the module housing 210 and the internal structure of the lifting module 200; simultaneously, lead one side that sound hole 213 deviates from the installation cavity through setting up blocking part 320 at the second, still make blocking part 320 can lead the oral area of sound hole 213 and external intercommunication from the second directly to second lead sound hole 213 production shutoff effect, perhaps say so, can prevent basically that external dust and steam from getting into second and lead sound hole 213 to external dust and steam more can not get into the installation cavity. In addition, when the blocking portion 320 is disposed on a side of the second sound guiding hole 213 departing from the installation cavity, since the distance between the blocking portion 320 and the front housing 100 is relatively short, the size of the positioning portion 310 is also relatively small, and it is not necessary to reserve a moving space for the positioning portion 310 inside the lifting module 200, which can further prevent the overall structural strength of the lifting module from being reduced due to the fact that many cavities need to be reserved inside the lifting module 200.

Alternatively, as shown in fig. 3 and 4, the module housing 210 of the lifting module 200 may adopt a semi-open structure, that is, the exposed portion of the lifting module 200 in the extended state may be set to be a closed structure, and the inside of one side of the lifting module 200 close to the front housing 100 is provided with the receiving cavity 214, and the portion of the lifting module 200 in the extended state that is not exposed may be set to be an open structure, that is, the shielding structure may not be provided on one side of the lifting module 200 facing the front housing 100, so as to enable the blocking portion 320 contained in the module housing 210 to be directly connected with the positioning portion 310 and fixed on the front housing 100 through the positioning portion 310, the connection process is simple and convenient, and materials are saved.

Further, as shown in fig. 3 and 4, the blocking portion 320 may be configured to be slidably attached to the module housing 210, in which case, the matching relationship between the blocking portion 320 and the second sound guiding hole 213 disposed on the module housing 210 is further improved, so that the blocking relationship of the blocking portion 320 to the second sound guiding hole 213 is more reliable, and external dust and water vapor are further prevented from entering the installation cavity from the second sound guiding hole 213. Specifically, the friction between the blocking part 320 and the module case 210 may be reduced by reducing the friction coefficient of the materials selected for the blocking part 320 and the module case 210, and the like; of course, in the actual operation process, because of other factors such as machining precision, cause to have the technical scheme in certain gap between stop part 320 and the module shell 210 also the utility model discloses a within the scope of protection.

In order to reduce the difficulty when the blocking portion 320 is received in the receiving cavity 214, it is preferable that a predetermined gap is formed between the receiving cavity 214 and the blocking portion 320 partially received in the receiving cavity 214 when the lifting module 200 is in the retracted state, as shown in fig. 4. Specifically, by increasing the size of the receiving cavity 214 in the corresponding direction, a preset gap can be ensured between the portion of the blocking portion 320 received in the receiving cavity 214 and the cavity wall of the receiving cavity 214. The corresponding direction may be the length, width, thickness, etc. of the barrier 320 itself.

By adopting the above technical scheme, the size of the accommodating cavity 214 in a certain direction is larger than the size of the blocking portion 320 in the corresponding direction, on one hand, in the process of retracting the lifting module 200 into the electronic device, the blocking portion 320 is more easily accommodated into the accommodating cavity 214; on the other hand, even if the lifting module 200 does not move in the preset moving direction but slightly deflects during the retraction process, the process of accommodating the blocking portion 320 into the accommodating cavity 214 is not substantially affected; in addition, in summer or under the condition that the temperature of the environment where the electronic device is located is relatively high, even if the barrier portion 320 expands to a certain extent, due to the relatively large size of the receiving cavity 214, the barrier portion 320 can still be received in the receiving cavity 214.

Furthermore, the electronic device provided by the embodiment of the present invention may further include an elastic reset element, one end of the elastic reset element may be connected to the bottom of the receiving cavity 214, the other end of the elastic reset element may be connected to the blocking portion 320, and the elastic reset element is in a stretching state when the lifting module 200 is in the stretching state, that is, the elastic reset element connected to the lifting module 200 may be stretched when the lifting module 200 is switched from the retracting state to the stretching state, so that the elastic reset element has a predetermined elastic force when the lifting module 200 is in the stretching state, and further, when the lifting module 200 is switched from the stretching state to the retracting state, the elastic reset element may provide a reset force for the blocking portion 320 under the effect of the elastic reset element, assist the blocking portion 320 to move towards the bottom of the receiving cavity 214, so as to prevent mutual interference between the cavity wall of the receiving cavity 214 and the blocking portion 320, so that the blocking portion 320 cannot be retracted into the receiving cavity 214.

Specifically, the elastic reset piece may be a rubber band or a compression spring, the elastic reset piece may be fixedly connected to the cavity bottom of the accommodating cavity 214 and the blocking portion 320 in a manner of clamping or the like, and parameters such as an elastic coefficient and a maximum elastic force of the elastic reset piece may be determined according to actual conditions such as a gap between the blocking portion 320 and the accommodating cavity 214, a roughness of the blocking portion 320, and the like.

As described above, the shielding member 300 may be made of a hard or flexible material, and considering that, during the operation of the electronic device, as the lifting module 200 switches between the extended state and the retracted state, the blocking portion 320 and the lifting module 200 may generate a relative movement process, in order to prevent the interference process such as relative sliding between the blocking portion 320 and the lifting module 200 from scratching the module housing 210, preferably, the blocking portion 320 may be a flexible structural member, so that even if the sliding fit process between the blocking portion 320 and the module housing 210 of the lifting module 200 occurs, the shielding member 300 may not scratch or even damage the lifting module 200; in addition, in the process of being stored in the storage cavity 214, even after the blocking portion 320 with certain flexibility touches the cavity wall of the storage cavity 214, the blocking portion 320 can continue to move to the deep position of the storage cavity 214 by generating elastic deformation, which basically ensures that the blocking portion 320 can be stored in the storage cavity 214 without being influenced by other conditions.

Specifically, the blocking portion 320 may be made of a flexible material such as rubber or silicone, and the positioning portion 310 and the blocking portion 320 may be formed by integral injection molding. The positioning portion 310 and the front housing 100 may be fixedly connected, or the positioning portion 310 and the front housing 100 may be in a limit fit relationship in the moving direction of the lifting module 200 by means of clamping or limiting.

As described above, the receiving cavity 214 is used for receiving at least a portion of the blocking portion 320, and the blocking portion 320 extends into the receiving cavity 214 from the opening of the receiving cavity 214 along the moving direction of the lifting module 200 as the lifting module 200 is retracted into the electronic device. In the case that the blocking portion 320 is made of a hard material, the receiving cavity 214 needs to extend along the moving direction to ensure that the blocking portion 320 can be received in the receiving cavity 214; and under the condition that the blocking part 320 is a flexible structural member, the limitation on the extending direction of the accommodating cavity 214 is relatively small, for example, the accommodating cavity 214 can be obliquely arranged relative to the moving direction of the lifting module 200, compared with the above scheme, the depth of the accommodating cavity 214 with the structure is relatively large, so that the blocking part 320 with a larger size can be accommodated, and the shielding relation between the blocking part 320 and the second sound guide hole 213 can be more stable and reliable.

Preferably, as shown in fig. 3 and 4, the receiving cavity 214 may have an arc-shaped structure, and the receiving cavity 214 may extend in a direction away from the front case 100 along a direction in which the cavity opening of the receiving cavity 214 is located toward the cavity bottom of the receiving cavity 214. The maximum depth value which can be achieved by the accommodating cavity 214 with the structure is relatively larger, so that the size limit of the blocking part 320 in the moving direction of the lifting module 200 is smaller; in addition, when the accommodating chamber 214 has an arc-shaped structure, the degree of elastic deformation generated when the blocking portion 320 moves along the chamber wall of the accommodating chamber 214 is relatively small and relatively gentle as the operation process of retracting the lifting module 200 into the electronic device proceeds, and when the blocking portion 320 is a flexible structure, the blocking portion 320 can be accommodated in the accommodating chamber 214 by generating a certain deformation.

In addition, when the containing cavity 214 adopts the above scheme, for the scheme that the containing cavity 214 extends along the moving direction of the lifting module 200 and is arranged inside the module shell 210 towards one side of the front shell 100, the structural strength of the surrounding part of the position where the containing cavity 214 is located in the module shell 210 can be improved to a certain extent due to the fact that the containing cavity extends towards the direction back to the front shell 100, and the condition that the module shell 210 is slightly collided with to cause depression when the lifting module 200 is in the extending state can be prevented. Specifically, the parameters such as the arc and the depth of the receiving cavity 214 may be determined according to actual factors such as the maximum displacement of the lifting module 200 relative to the front housing 100 and the actual position of the second sound guide hole 213, which are not limited herein.

In order to further reduce the difficulty of the blocking portion 320 being received in the receiving cavity 214 along with the retraction process of the lifting module 200, preferably, as shown in fig. 3, an end of the blocking portion 320 facing away from the positioning portion 310 may be provided as a guiding end having a chamfer or the like. Specifically, each edge and corner of the end of the blocking portion 320 can be chamfered, so that in the process of accommodating the blocking portion 320 into the accommodating cavity 214, the guiding and avoiding effects can be provided for the movement process of the blocking portion 320 relative to the lifting module 200 by using the guiding end, and the blocking portion 320 can be smoothly accommodated into the accommodating cavity 214.

Further, the inner wall of the accommodating cavity 214 may be provided with a first limiting member, the blocking portion 320 may be provided with a second limiting member, and under the condition that the lifting module is in the extended state, the first limiting member and the second limiting member are in limit fit, so as to prevent the blocking member 320 from moving in a direction away from the accommodating cavity 214 all the time, which causes a phenomenon that the blocking member 320 is disengaged from the accommodating cavity 214, which may cause the blocking member 320 to be unable to extend into the accommodating cavity 214 again, thereby causing adverse effects on normal use of the electronic device.

Specifically, the first limiting part and the second limiting part may be both of a bump type structure, and the first limiting part and the second limiting part may be arranged oppositely, so that when the lifting module is in an extended state, the first limiting part can be in limit fit with the second limiting part, and the blocking part 320 is limited from being separated from the accommodating cavity 214.
