Description

Technical Field

[0001] This application belongs to the field of electronic product technology, and specifically relates to an electronic device. Background Technology

[0002] With the continuous development of electronic devices, people have higher and higher requirements for the waterproof level of electronic devices, that is, higher requirements for the sealing performance of electronic devices. At the same time, in order to prevent the sealing and waterproofing of electronic devices from failing due to the pressure difference between the inside and outside of the device, it is usually necessary to add pressure balance holes to the electronic devices.

[0003] The frame and back cover of an electronic device enclose an internal space that needs to be connected to the external environment through a pressure equalization vent. This vent is typically located between the rear camera and the decorative ring. Specifically, a tiny gap is formed between the rear camera and the decorative ring, connecting the internal space of the electronic device to the external environment, thus allowing this tiny gap to function as a pressure equalization vent. However, because this tiny gap is so small, it is easily blocked by foreign objects, thus the pressure equalization vent in this technology suffers from the problem of being easily blocked by foreign objects. Utility Model Content

[0004] The purpose of this application is to provide an electronic device that can solve the problem that the air pressure balance hole in the related technology is easily blocked by foreign objects.

[0005] This application provides an electronic device, including a frame and a back cover. The frame and the back cover are connected to form a first space. The frame is provided with a functional hole for communicating with the external environment, and the frame is also provided with an air pressure balance hole. The air pressure balance hole connects the first space and the functional hole, so that the first space is connected with the external environment through the air pressure balance hole and the functional hole.

[0006] In this embodiment, the functional hole is an existing hole on the frame. Since the pressure balance hole connects the first space and the functional hole, the first space is connected to the external environment through the pressure balance hole and the functional hole. This minimizes or eliminates the pressure difference between the inside and outside of the electronic device, thus preventing any impact on its sealing and waterproofing performance. Furthermore, because the diameter of the functional hole is much larger than the tiny gap formed between the rear camera and the decorative ring, the problem of the pressure balance hole being easily blocked by foreign objects is avoided. Additionally, since this application reuses existing functional holes on the frame, the number of openings on the frame is reduced, thus preventing any impact on the waterproofing performance of the electronic device.

Detailed Implementation

[0009] The technical solutions of the embodiments of this application will be clearly described below with reference to the accompanying drawings. Obviously, the described embodiments are only some, not all, of the embodiments of this application. All other embodiments obtained by those skilled in the art based on the embodiments of this application are within the scope of protection of this application.

[0010] The terms "first," "second," etc., used in the specification and claims of this application are used to distinguish similar objects and not to describe a specific order or sequence. It should be understood that such use of data can be interchanged where appropriate so that embodiments of this application can be implemented in orders other than those illustrated or described herein, and the objects distinguished by "first," "second," etc., are generally of the same class and the number of objects is not limited; for example, a first object can be one or more. Furthermore, in the specification and claims, "and / or" indicates at least one of the connected objects, and the character " / " generally indicates that the preceding and following objects are in an "or" relationship.

[0011] The electronic devices disclosed in this application will be described in detail below with reference to the accompanying drawings, through specific embodiments and application scenarios.

[0012] Please refer to Figure 1 and Figure 2 This application discloses an electronic device, which includes a frame 100 and a back cover 200.

[0013] Both the frame 100 and the back cover 200 are basic components of the electronic device. The frame 100 and the back cover 200 are connected to form a first space 310, in which components such as circuit boards and batteries of the electronic device can be housed. Optionally, to ensure the waterproof sealing of the first space 310, the frame 100 and the back cover 200 can be bonded together using a third sealant 840.

[0014] The frame 100 is provided with a functional hole 110 for communicating with the external environment, and the frame 100 is also provided with an air pressure balancing hole 120. The air pressure balancing hole 120 connects the first space 310 and the functional hole 110. In other words, the air pressure balancing hole 120 connects the first space 310 and the functional hole 110, so that the first space 310 is connected to the external environment. That is, the first space 310 is connected to the external environment through the air pressure balancing hole 120 and the functional hole 110, so that airflow can be exchanged between the first space 310 and the external environment. This allows the electronic device to achieve a small or even no internal and external air pressure difference through the functional hole 110 and the air pressure balancing hole 120. For example, when the external atmospheric pressure changes drastically, this can easily lead to an increase in the pressure difference between the inside and outside of the electronic device. At this time, air can flow normally through the functional hole 110 and the air pressure balancing hole 120, thereby preventing the waterproof sealing of the first space 310 from failing due to a large internal and external air pressure difference.

[0015] In this embodiment, the functional hole 110 is an existing hole on the frame 100. Since the pressure balance hole 120 connects the first space 310 and the functional hole 110, the first space 310 is connected to the external environment through the pressure balance hole 120 and the functional hole 110, so that the pressure difference between the inside and outside of the electronic device is small or even non-existent, thereby avoiding affecting the sealing and waterproof performance of the electronic device. At the same time, since the diameter of the functional hole 110 is much larger than the size of the tiny gap formed between the rear camera and the decorative ring of the electronic device, this can avoid the problem of the pressure balance hole 120 being easily blocked by foreign objects. In addition, since this application reuses the existing functional hole 110 on the frame 100, this reduces the number of openings on the frame 100, thus avoiding affecting the waterproof performance of the electronic device.

[0016] Meanwhile, since this application reuses the existing functional holes 110 on the frame 100, the number of openings on the outer surface of the frame 100 is reduced, thus avoiding affecting the appearance performance of the electronic device, that is, avoiding damage to the appearance integrity of the electronic device.

[0017] In this application, when it is necessary to perform an airtightness test on the entire electronic device, please refer to... Figure 2The operator can insert the sealing plug 900 into the functional hole 110 to block the functional hole 110, thereby blocking the air pressure balance hole 120, so that the first space 310 is not connected to the external environment. At this time, an airtightness test can be performed to determine whether the first space 310 is effectively sealed.

[0018] Optionally, the aforementioned functional holes 110 may include a SIM card ejector hole, a charging hole, a handset output hole, and a microphone hole. Each functional hole 110 may be provided with a pressure balancing hole 120 in the area of ​​the frame 100 near each functional hole 110, so that the corresponding functional hole 110 is connected to the corresponding pressure balancing hole 120. That is, the number of pressure balancing holes 120 on the electronic device can be multiple, and the multiple pressure balancing holes 120 can be distributed to quickly reduce the pressure difference between the inside and outside of the electronic device during the process of balancing the pressure difference between the inside and outside of the electronic device.

[0019] In another embodiment, the pressure balancing hole 120 can be located near one of the SIM card pin hole, charging hole, earpiece sound output hole and microphone hole, and connected to that one. That is, the pressure balancing hole 120 can be provided near only one of the multiple functional holes 110 of the frame 100, so that the number of pressure balancing holes 120 on the electronic device can be reduced. This allows the internal and external air pressure of the electronic device to be balanced, while avoiding affecting the structural strength of the frame 100.

[0020] Optionally, in the direction of the central axis of the functional hole 110, the functional hole 110 and the pressure balance hole 120 are offset, that is, the central axis of the functional hole 110 does not coincide with the central axis of the pressure balance hole 120, so that a blocking structure can be formed at the connection between the functional hole 110 and the pressure balance hole 120. This blocking structure can specifically be the end structure of the functional hole 110 or the end structure of the pressure balance hole 120, and this blocking structure can directly block some impurities to prevent impurities from entering the pressure balance hole 120 and the first space 310. Of course, in other embodiments, the central axis of the functional hole 110 and the central axis of the pressure balance hole 120 can also coincide, so that in the direction of the central axis of the functional hole 110, the functional hole 110 and the pressure balance hole 120 are opposite and connected. In order to prevent impurities from entering the pressure balance hole 120 and the first space 310, the embodiments of this application can add an additional blocking structure at the connection between the functional hole 110 and the pressure balance hole 120 to block at least some impurities.

[0021] Optionally, the functional hole 110 typically extends along the length or width of the electronic device, that is, the functional hole 110 is typically a straight hole. The central axis of the functional hole 110 may intersect with the central axis of the pressure balance hole 120, so that the pressure balance hole 120 can be a hole that extends at an angle relative to the functional hole 110, so as to facilitate communication with the functional hole 110. Since the pressure balance hole 120 extends at an angle relative to the length or width of the electronic device, the sidewall of the pressure balance hole 120 has a certain effect of blocking impurities.

[0022] In another embodiment, since the pressure balancing hole 120 is relatively close to the first space 310, that is, relatively close to the interior of the electronic device, in order to facilitate the processing of the pressure balancing hole 120, the central axis of the functional hole 110 is parallel to the central axis of the pressure balancing hole 120, that is, the extension direction of the central axis of the functional hole 110 is parallel to the extension direction of the central axis of the pressure balancing hole 120, so that the pressure balancing hole 120 also extends along the length or width direction of the electronic device, that is, the pressure balancing hole 120 is a horizontally extending air hole, which can reduce the difficulty of processing the pressure balancing hole 120.

[0023] In this embodiment, since the central axis of the functional hole 110 and the central axis of the pressure balance hole 120 are staggered and parallel on the frame 100, in order to ensure that the functional hole 110 and the pressure balance hole 120 are connected, in the specific processing of the functional hole 110 and the pressure balance hole 120, the distance between the central axis of the functional hole 110 and the central axis of the pressure balance hole 120 can be slightly smaller than the sum of the radius of the functional hole 110 and the radius of the pressure balance hole 120, so that the functional hole 110 and the pressure balance hole 120 can directly penetrate each other during the processing of the functional hole 110 and the pressure balance hole 120, so as to achieve the effect of communication between the two at the sidewall of the functional hole 110 and the sidewall of the pressure balance hole 120. It should be noted that when at least one of the functional hole 110 and the pressure balance hole 120 is an irregularly shaped hole, the embodiments of this application can also use a direct contact method to connect the functional hole 110 and the pressure balance hole 120, as long as the distance between the central axis of the functional hole 110 and the central axis of the pressure balance hole 120 is controlled.

[0024] Alternatively, this application can also connect the functional hole 110 and the air pressure balance hole 120 in a non-penetrating manner. For example, when the distance between the functional hole 110 and the air pressure balance hole 120 is far, the frame 100 can also be provided with a connecting hole. One end of the connecting hole is connected to the functional hole 110, and the other end of the connecting hole is connected to the air pressure balance hole 120. That is, the connecting hole connects the functional hole 110 and the air pressure balance hole 120. At this time, the central axis of the connecting hole intersects with the central axis of both the functional hole 110 and the air pressure balance hole 120.

[0025] Optionally, in the thickness direction of the electronic device, the orthographic projection of the central axis of the functional hole 110 and the orthographic projection of the central axis of the air pressure balance hole 120 may not coincide.

[0026] In another embodiment, in the thickness direction of the electronic device, the orthographic projection of the central axis of the functional hole 110 coincides with the orthographic projection of the central axis of the pressure balance hole 120. Since the extension direction of the central axis of the functional hole 110 is parallel to the extension direction of the central axis of the pressure balance hole 120, the functional hole 110 and the pressure balance hole 120 are arranged sequentially in the thickness direction of the electronic device. This makes the distance between the functional hole 110 and the pressure balance hole 120 relatively close, so that the functional hole 110 and the pressure balance hole 120 can be set more compactly in the thickness direction of the electronic device, and thus occupy less space in the length or width direction of the electronic device, so as to facilitate the placement of other components in the electronic device.

[0027] Optionally, when the aforementioned functional hole 110 and pressure balance hole 120 are connected by a connecting hole, since the functional hole 110 and pressure balance hole 120 are arranged at intervals in the thickness direction of the electronic device, the connecting hole specifically extends along the thickness direction of the electronic device, that is, the connecting hole is a straight hole. This facilitates the processing of the connecting hole, and the sidewall of the connecting hole can directly block some impurities to prevent impurities from entering the pressure balance hole 120 and the first space 310.

[0028] Meanwhile, since the orthographic projection of the central axis of the functional hole 110 coincides with the orthographic projection of the central axis of the pressure balance hole 120 in the thickness direction of the electronic device, the distance between the functional hole 110 and the pressure balance hole 120 is relatively close. Therefore, the size of the connecting hole in the thickness direction of the electronic device is relatively small, which makes the space occupied by the connecting hole in the frame 100 smaller. That is, this arrangement is less likely to damage the structural strength of the frame 100.

[0029] Optionally, the pressure balancing hole 120 may include a first hole segment 121 and a second hole segment 122 that are coaxially arranged and connected in sequence. The first space 310, the first hole segment 121, the second hole segment 122 and the functional hole 110 are connected in sequence, and the cross-sectional area of ​​the first hole segment 121 may be equal to or less than the cross-sectional area of ​​the second hole segment 122.

[0030] In another embodiment, the cross-sectional area of ​​the first orifice 121 can be larger than the cross-sectional area of ​​the second orifice 122. When the air pressure in the first space 310 is greater than the air pressure in the external environment, that is, when the gas flows from the first orifice 121 to the second orifice 122, the gas flow rate will increase. This allows the high-pressure gas in the first space 310 to be discharged more quickly, so as to avoid the problem of the first space 310 failing to seal due to the expansion inside the electronic device.

[0031] Please refer to Figure 1 and Figure 2 The electronic device may also include a speaker assembly 400 and a display assembly 500. The speaker assembly 400 enables the electronic device to produce sound, and the display assembly 500 enables the electronic device to display. The display assembly 500 and the back cover 200 may be located on opposite sides of the frame 100, that is, the display assembly 500 is located on the side of the frame 100 away from the back cover 200, and the frame 100 and the display assembly 500 are connected to form a second space 320. The first space 310 and the second space 320 may not be connected.

[0032] The frame 100 may also be provided with mounting holes 140, and part of the speaker assembly 400 may be disposed in the mounting holes 140. The speaker assembly 400 and the frame 100 may be bonded together by the second sealant 830 so that the speaker assembly 400 is separated from the first space 310 and the second space 320. The speaker assembly 400 faces the display assembly 500. The speaker assembly 400, the display assembly 500 and the frame 100 together form a sound guiding channel 150. At least part of the sound guiding channel 150 belongs to the second space 320, and the functional hole 110 is connected to the sound guiding channel 150.

[0033] Therefore, the present application embodiment enables the sound emitted by the speaker assembly 400 to be conducted to the external environment through the sound guide channel 150 and the functional hole 110, that is, the functional hole 110 can be used as the speaker sound outlet.

[0034] Optionally, in this embodiment, the number of functional holes 110 can be at least two, and the pressure balancing hole 120 can connect the first space 310 and each functional hole 110. In this case, there can be one pressure balancing hole 120, which is simultaneously connected to multiple functional holes 110; or, there can be multiple pressure balancing holes 120, each corresponding to and connected to each functional hole 110. Because there are a large number of functional holes 110, this can quickly achieve the effect of balancing the internal and external air pressure of the electronic device and improve the sound conduction speed. Of course, in other embodiments, the number of functional holes 110 can also be one.

[0035] To prevent moisture from entering the first space 310 and corroding the electronic components within it, the electronic device may also include a waterproof and breathable membrane 600. The frame 100 has a first sidewall 160 facing the first space 310, and a pressure balance hole 120 penetrates the first sidewall 160 to connect it to the first space 310. The waterproof and breathable membrane 600 can cover the first sidewall 160 to seal the pressure balance hole 120. While blocking moisture, the waterproof and breathable membrane 600 can also prevent interference with airflow exchange between the first space 310 and the external environment. Because the waterproof and breathable membrane 600 covers the first sidewall 160, meaning the connectable area between the waterproof and breathable membrane 600 and the first sidewall 160 is relatively large, this ensures the installation stability of the waterproof and breathable membrane 600, thereby ensuring the effectiveness of sealing the pressure balance hole 120. Furthermore, this method of setting up the waterproof and breathable membrane 600 is relatively simple and easy to operate.

[0036] In this embodiment, the plane containing the waterproof and breathable membrane 600 is parallel to the thickness direction of the electronic device. That is, the waterproof and breathable membrane 600 is a planar waterproof and breathable membrane, positioned along the thickness direction of the electronic device. This results in a relatively small space occupied by the waterproof and breathable membrane 600 in the length or width direction of the electronic device. Of course, in other embodiments, the plane containing the waterproof and breathable membrane 600 may intersect with the thickness direction of the electronic device.

[0037] Furthermore, as can be seen from the foregoing, since the functional hole 110 and the air pressure balance hole 120 are misaligned in the direction of the central axis of the functional hole 110, that is, the central axis of the functional hole 110 does not coincide with the central axis of the air pressure balance hole 120, the waterproof and breathable membrane 600 is not directly facing the functional hole 110. This can effectively reduce the risk of the waterproof and breathable membrane 600 being damaged when the electronic device is subjected to external water flow impact.

[0038] Optionally, the electronic device may further include a speaker assembly 400, which may be the same as the speaker assembly 400 described above. This speaker assembly 400 is disposed in the frame 100, and a first gap 330 exists between the speaker assembly 400 and the first sidewall 160. The waterproof and breathable membrane 600 is located within the first gap 330, meaning the waterproof and breathable membrane 600 can reuse the space between the speaker assembly 400 and the first sidewall 160 for installation, thereby improving the utilization rate of this space. In other words, the waterproof and breathable membrane 600 can fully utilize the space between the speaker assembly 400 and the first sidewall 160, which improves the overall structural compactness. Furthermore, since the waterproof and breathable membrane 600 does not occupy other space, it avoids affecting the installation of other components. Of course, in other embodiments, additional space may be reserved for installing the waterproof and breathable membrane 600.

[0039] Optionally, the speaker assembly 400 may include a speaker 410 and a bracket 420. A portion of the speaker 410 may be disposed within the aforementioned mounting hole 140, and the bracket 420 and the frame 100 may be bonded together by the aforementioned second sealant 830. At least a portion of the speaker 410 is located within the space enclosed by the bracket 420 and the frame 100. The frame 100, the speaker 410, and the bracket 420 may enclose the acoustic rear cavity of the speaker 410, and the volume of the enclosed acoustic rear cavity is relatively large. Optionally, to ensure the sealing of the acoustic rear cavity of the speaker 410, a sealing foam 820 may be provided between the bracket 420 and the frame 100.

[0040] In this embodiment, the waterproof and breathable membrane 600 can be located within the first gap 330 between the first sidewall 160 and the bracket 420. The waterproof and breathable membrane 600 can connect the first space 310 with the external environment. Since the acoustic rear cavity of the speaker 410 is sealed separately within the entire electronic device, i.e., it is not connected to the first space 310, the waterproof and breathable membrane 600 will not cause leakage in the acoustic rear cavity of the speaker 410. Of course, in other embodiments, the electronic device may not include the bracket 420. In this case, the speaker 410 can have its own acoustic rear cavity.

[0041] Optionally, the first sidewall 160 may be provided with a limiting groove 170 surrounding the air pressure balance hole 120. At least a portion of the waterproof and breathable membrane 600 may be located within the limiting groove 170, that is, the waterproof and breathable membrane 600 may be confined within the limiting groove 170 to further improve the installation stability of the waterproof and breathable membrane 600. At the same time, since the waterproof and breathable membrane 600 is confined within the limiting groove 170, this can improve the structural compactness of the frame 100 and the waterproof and breathable membrane 600. Of course, in other embodiments, the first sidewall 160 may not be provided with a limiting groove 170 surrounding the air pressure balance hole 120.

[0042] Alternatively, the waterproof and breathable membrane 600 can be installed on the first sidewall 160 using ordinary adhesive.

[0043] In another embodiment, the electronic device may further include a first sealant 810, and the waterproof and breathable membrane 600 may be bonded to the first sidewall 160 by the first sealant 810. This can ensure the adhesion and sealing between the waterproof and breathable membrane 600 and the first sidewall 160, thereby further ensuring the waterproof sealing effect on the first space 310, so that the electronic device disclosed in this application can have a waterproof rating of IPX8 or higher.

[0044] Optionally, the materials used to make the first sealant 810, the second sealant 830, and the third sealant 840 may be the same or different, and this application embodiment does not impose specific limitations on this.

[0045] Optionally, the electronic device disclosed in this application can be any electronic product that requires an air pressure equalization port 120, such as a mobile phone, tablet computer, laptop computer, PDA, and wearable device.

[0046] The embodiments of this application have been described above with reference to the accompanying drawings. However, this application is not limited to the specific embodiments described above. The specific embodiments described above are merely illustrative and not restrictive. Those skilled in the art can make many other forms under the guidance of this application without departing from the spirit and scope of the claims, and all of these forms are within the protection scope of this application.
